Keep optimism through IFPE and beyond Each week, we see more news of the dip occurring in the industrial market here in the U.S. Markets and shipments are down and have been across the board, particularly in the fluid power space. The NFPA has indicated mobile hydraulic, industrial hydraulic and pneumatic shipments decreased when compared to last year and decreased when compared to last month. And, U.S. manufacturing technology orders fell 15% in November from the previous month to $320 million, according to a report published by The Association for Manufacturing Technology. But these despite indicators manufacturers and users are optimistic about the industry. Alan Beaulieu of ITR Economics echoed these sentiments at the A3 Conference last month, where he said he expects industrial declines to continue until mid-2020, but we’ll see a pick-up in Q3 and Q4. And, notably, he pointed out that currently, there is tough competition for employees. This is reflected in our market, too, as Fluid Power World’s Ken Korane pointed out last month. Demand for fluid power specialists is still high, with opportunities for better jobs and better pay a strong possibility in the current market, Korane said.

Add all this news into the fact that it’s an IFPE year, and we’re bullish on fluid power. Things may be trending downward but with registrations trending at a record pace for CONEXPO-CON/AGG and IFPE next month, and an overall positive mindset, things are continuing to look up for fluid power. It will be particularly interesting to hit the ground at IFPE and learn what manufacturers and users are saying about the industry and where it’s headed for the second half of this year and into 2021. Stay tuned for reports from the show, where our editorial team will be highlighting industry news with show daily newsletters, daily blogs, videos and more. Our post-show coverage will continue for months to come. In the meantime, turn to page 37 for our record coverage of IFPE, with in-depth looks at the many education offerings, a full exhibitor list, show maps, technical component briefs and a round-up on mobile machine electrification highlights.

FROM THE FIELD Paul J. Heney • VP, Editorial Director

Fluid power manufacturers make the LEAP Winners of the second annual LEAP Awards were announced in December 2019, and competition was fierce in the two fluid power categories. This year, judges awarded a Gold, Silver and Bronze in each of the categories, which stretched across mechanical and electrical engineering disciplines. In Pneumatics, Festo was awarded the gold for its DHEF adaptive shape gripper, which adapts to workpiece size and shape and picks up, gathers, and sets down single or multiple objects without manual adjustment. The gripper offers maximum gripping flexibility with minimal engineering. The adaptive shape gripper automatically grips mixed objects with multiple shapes, unaligned objects, and numerous objects at once. It gently forms around an object and is suitable for gripping fragile items and human/machine interaction. Taking Silver was Emerson Aventics’ Smart Pneumatics Analyzer (SPA). This product enhances preventative maintenance and energy optimization by analyzing and visualizing pneumatic systems. By digitizing the pneumatic environment, the SPA helps pneumatic system users quickly and easily see the potential benefits of integrating IIoT in their machine with a few simple steps. The monitor initially detects the system operating state, analyzes data, and provides this processed information to users for status-oriented maintenance. Finally, Parker Hannifin took the Bronze for its P2M Industrial Ethernet Node, which is optimized to be cost effective with the intention of providing the opportunity for customers with traditionally hardwired networks to migrate to an Ethernet solution that is intuitive, easy to use, install and maintain; all while reducing overall costs. In Hydraulics, Husco was awarded the Gold award for its Exacto Pilot Interrupter System, which enables digital control of any 4

pilot operated mobile machine. This product was conceived to be fitted to current market machines either as a factory fit or in the field to give safe, autonomous, augmented, or remote digital control of the machine. It uses pressure transducers, solenoid valves, a wiring harness, and a precision controller with electrohydraulic control algorithms and software. All of this is combined into a single subsystem allowing for ease of installation and integration with current production systems and other systems such as machine control or remote operation. The Silver award went to Bosch Rexroth for its CytroBox — The Hydraulic Power Unit of the Future. With a compact and energyefficient design, the intelligent CytroBox is suited for a variety of hydraulic power applications, and comes fully equipped with a variable speed drive, electronic controller, sensor package, and its own IoT solution. Finally, the Bronze award was awarded to Linde Hydraulics Corp. for its Fast Stroking Concrete Pump HPV135-02T. The company developed a new faster stroking variable axial-piston pump for use in concrete pump applications. Constructive changes with the variable axial-piston pump’s internal design have allowed Linde to offer a pump with a significantly faster response time.

KORANE’S OUTLOOK Ken Korane • Contributing Editor

Embrace hydraulics, or call it quits

It’s

It’s barely February and we already know the ﬂuid-power industry’s news of the year: Danfoss is acquiring Eaton Hydraulics for $3.3 billion. It paints a stark contrast between two corporations’ view of the future of hydraulics.

Eaton’s CEO Craig Arnold said the sale “is part of the ongoing transformation of Eaton into a higher growth company with better earnings consistency.” One might say, in less polite terms, they’re happy to unload this cyclical laggard that’s been a drain on profits and, instead, focus on selling electrical motors, switches and power supplies. On the other hand, said Eric Alström, President of Danfoss Power Solutions, “Hydraulics is our core, and we have for years strengthened our business through high customer focus, as well as through significant investments in technology leadership. I believe our customers will benefit from combining these two businesses into a full-line hydraulics player dedicated to innovation and with a broad offering of products, robust distribution channels and tremendous geographic reach.” His comments are in line with a presentation on the company’s R&D efforts at the recent Fluid Power Technical Conference hosted by Fluid Power World in Cleveland. Senior Systems Engineer Simon Nielsen said, “It’s part of our Danfoss DNA that as the times change we invest and innovate to remain successful. And that’s what we have especially been doing the last few years.” He cited electrification as a global megatrend that holds strong potential in fighting pollution and climate change. In the mobileequipment arena that means intelligently melding hydraulics and electric drives, and Danfoss intends to be a key player in that transformation. “It will create new opportunities in our markets, even though hydraulics market share will undoubtedly decline over time,” he said. Recent moves back that up. They’ve acquired Ducato and Axco Motors out of Finland and UQM in Colorado that bring years of experience in mobile electrification; and formed a strategic partnership with Autonomous Solutions Inc. to tap expertise in driverless machines. On the hydraulics side, they purchased Artemis Intelligent Power, whose digital-displacement pumps (DDPs) are fast, accurate and extremely efficient, even at low flows and partial loads. Experts say the technology, which minimizes power losses in hydraulic circuits, could be a “game-changer” for electrification.

| Danfoss

The main concerns with battery electric vehicles are range, battery size and cost. There is an ongoing effort among OEMs to increase efficiency and downsize the batteries, and the DDP is a tool to do just that, said Nielsen. Tests show that battery-powered excavators that use digital displacement pumps and improved control-valve architecture could achieve the same working capability with 20% to 25% less battery capacity. And on diesel-powered excavators, changing to a DDP results in double-digit percent increases in productivity and fuel economy. “Any improvements in drivetrain efficiency, especially hydraulic system efficiency, will continue to have merit, not only for battery electric vehicles where it translates directly into range and battery size, but on any system that is seeking to minimize fuel consumption and reduce emissions,” he said. Many companies are joining the electric revolution, ranging from traditional engine manufacturers to producers of gearboxes and axles. Astute hydraulic suppliers hold some key advantages, given decades of experience working with continuously variable transmissions, hybrid designs, vehicle power management systems and customized application software. Danfoss aims to combine the most modern hydraulic technology with the best in electric powertrain technology, he continued. “My point is that we don’t see this as an either/or situation. We have taken the role of becoming a multi-technology specialist, we think it’s an inevitable symbiotic meshing of technology that is taking place over time.”

ASSOCIATION WATCH Edited by Mike Santora • Associate Editor

IFPS opens Fluid Power Hall of Fame 2020 nominations In its call of nominations, the International Fluid Power Society said that the success of the fluid power industry is not in its hardware, pumps, valves, cylinders, and hoses — but rather the success is through the efforts of its dedicated individuals — innovators, researchers, application engineers, educators, as well as sales and service personnel. These people are the reasons that the industry continues to thrive.

This special award has been established to acknowledge those individuals who have dedicated their careers, and have made significant contributions, to fluid power technology. In 2019, 11 individuals were inducted into the Hall of Fame, with six of them being posthumous.

2020 nominations will be accepted through April 15. Any person can nominate an individual, living or deceased, who demonstrated excellence within their 25-plus year fluid power career. Their career must be verifiable. The nomination form is simple and other than contact information, only requires a brief description of why the person is being nominated. Those nominated are asked to complete a 13-question application. A panel of judges review the applications and select the class of Inductees. Inductees will be honored at a special dinner later this year. Nominations can be submitted at www.fluidpowerhalloffame.org. FPW

University Fluid Power Clubs bring interest to industry The NFPA Technology and Education Foundation launched a new program last year to support Fluid Power Clubs at the college level. The goal of the clubs is to get engineering students introduced to and interested in fluid power, support club activities, and connect students to industry professionals to learn about careers in fluid power.

Four-year colleges or universities that offer a Bachelor of Science degree are eligible to apply. Clubs must have at least three student members with one at or below the junior level. The college must also provide a faculty advisor who oversees fluid power club activities and must offer at least one course that has fluid power content (hydraulics or pneumatics). Students will learn about fluid power while working on educational and technical projects, and other fun activities, including the NFPA Vehicle Challenge, access to guest speakers and mentors, job opportunities and leadership experience and professional development.

The Colorado State University created a club last year. According to Riley Abbott, President of the Colorado State University Fluid Power Club, membership has been growing, from three to 11 members. “The club hopes to build on its momentum to make sure that Colorado State University has a place for students to learn about hydraulics and pneumatics,” Abbot said. “The group decided on focusing on three different aspects of the club: knowledge through application, guidance through networking, and giving back through service. One of the ideas for this semester that has drawn the most support has been a competition between two teams to see who can make a device to lift the most weight! “The club has found a great home at Colorado State University where it can nurture interested minds on fluid power and will continue to do so!” FPW

Redesigned hydraulic system speeds loading on new excavator

With its PC2000-11 hydraulic excavator, Komatsu America, has created a machine that is designed to load 70- to 200-ton rigid frame haul trucks faster. Equipped with an EPA Tier 4 Final certified engine, the PC2000-11 has more horsepower and a new engine-pump control for faster cycle times and improved multifunction performance. Redesigned hydraulics and cylinder seals contribute to higher productivity and performance. 14

“The PC2000-11 is designed to load 70- to 200-ton rigid frame haul trucks and is an excellent tool for stripping overburden, loading coal, and loading shot rock,” said Robert Hussey, product marketing manager, Komatsu America. “The PC2000-11 has a simplified power module (cooling package, engine, PTO, and hydraulic pumps) which provides excellent accessibility to major components, low noise levels in the cab, and reduces labor hours when it comes time for planned overhaul.” The PC2000-11 offers improved multifunction performance, and a productivity increase up to 12%, and can therefore load more

trucks per shift. The redesigned hydraulic system monitors work equipment loads and optimizes hydraulic flow based on operating conditions. The PC2000-11 is equipped with selectable working modes to tailor machine performance to application requirements, including the all new “Power Plus” mode. Increased engine power and new engine pump control logic give the PC2000-11 faster cycle times. According to Hussey, “Improvements were made to the hydraulic system of the PC2000-11 with three main objectives: improve multifunction performance, increase pump absorption from the 12% increase in engine net horsepower, and increase fuel efficiency.” New for the PC2000-11 are electronic proportional control (EPC) valves which have greatly improved multifunction performance, Hussey added. The machine controller calculates engine power and pump absorbing torque based on selectable working modes (Power Plus, Power, Economy, Economy 1) resulting

in greater hydraulic power at maximum pressure, faster hydraulic speed/cycle times across the flow pressure curve from greater available engine torque, and up to 12% additional machine productivity. To increase efficiency and reduce hydraulic loss, a swing priority circuit was added to the machine to remove the need for an independent swing pump. A hydraulic filter bypass detection system was added to alert the operator if the return filter is clogged — this system also transmits an alert via KOMTRAX, Komatsu’s remote monitoring telematics system. The PC2000-11 has an electronically controlled hydraulic variable-speed fan which provides cooling to the machine based on application demand, reducing fuel consumption. Finally, the return piping diameter was increased to keep hydraulic oil temperatures cool and increase hydraulic efficiency. In addition, extended component life comes with thicker, stronger boom plates and castings; strengthened track and center www.fluidpowerworld.com

frames; larger diameter carrier rollers and improved hydraulic cylinder seals. The new seals on work equipment cylinders enable the PC2000-11 to withstand the most abrasive applications. “Heat resistant hydrogenated nitrile butadiene rubber (HNBR) is used in hydraulic component seals, rod and piston seals in cylinders, and in hydraulic hoses. HNBR is known for its strength and retention properties after long term exposure to heat, oil, and chemicals,” Hussey said. “Hydraulic hoses are estimated to last 1.5 – 2.0 times longer than conventional hoses. All hoses and seals of the PC2000-11 are heat resistant, improving hydraulic circuit life and reliability.” In addition, a scraper and sub dust seal have been added to the hydraulic cylinders to prevent dust entry. Total sealing of the cylinder (including the piston portion) contributes to a clean and reliable hydraulic circuit. “These improvements were made to 2 • 2020

Hydraulic cylinders help revolutionize oilfield pipe cleaning

A machine that’s been 10 years in the making is now seeing success, thanks to hydraulic cylinders from Yates Industries. When Thomas Services La LLC of New Iberia, La. decided to develop a completely new concept and class of machine for oilfield pipe cleaning, they committed to creating a new higher standard for the definition of ‘clean pipe.’ Early on during the conceptual design phase, they determined that hydraulic cylinders were the best solution for many of the operations the machine would complete. “Working with Yates Industries was a very clear decision,” said William Thomas, P.E. of Thomas Services. “Their products are just far superior.” The Scorpion Tubular Maintenance System (TMS) cleans the internal and external surfaces of any steel tubulars. The Scorpion defines cleaning to include removal of mud, oils, rust, scale, coatings, liners, cement and other matter from internal and external surface of tubulars. The requirement to clean tubulars is a fundamental step in the process of maintaining, inspecting, prepping, and/or salvaging tubulars for a variety of needs in the oil and gas industry.

The Scorpion TMS’ patented designs are based around versatility and capability. It allows users to accommodate any type of tubulars covering outer diameter size ranges of 1 to 48 in. OD and tubular lengths per user specifications ranging anywhere from 1 to 100 ft long. It also allows users to choose from an array of cleaning techniques, processes, and cleaning media methods including high volume water blasting and jetting at variable pressures typically ranging from 3,000 to 20,000 psi, with the option to increase pressure ratings across the system for ultrahigh pressure (40,000 psi) water blasting for special applications requiring extreme pressures. The Scorpion TMS also includes a patented and powerful hydraulic powered wire wheel brusher with an automated and mechanical floating feature for brushing external surface of tubulars. Airpowered cleaning devices can also be used with the 2 • 2020

Scorpion IDS cleaning system instead of water powered devices if preferred. “The Scorpion TMS is a state-ofthe-art pipe cleaning machine with revolutionary patented technology, which allows it to redefine pipe cleaning,” Thomas said. The Scorpion was developed to effectively, efficiently and safely handle any condition of Scorpion TMS (Gen. II) tubulars that may arise. Other pipe cleaning systems are limited. The Scorpion TMS is engineered to transfer user desired minimum or maximum amount of cleaning power to the tubular with attention to fluid mechanics, horsepower, and precision controls. The Scorpion maintains a minimal footprint, about 50% shorter than other systems thanks to its ID cleaning system and compact OD cleaning system. Enhanced with its pipe rotation system, the Scorpion TMS cleans the internal and external of each stationary and/

or spinning tubular with lateral flow of tubulars incoming to and outgoing from the system. Pipe cleaning machines are used in the oil and gas industry for systematic maintenance of valuable tubular assets such as drill pipe and work string tubulars. Clean drilling and exploration tubulars are imperative to maintain healthy assets. Such tubulars are expensive and often used in critical, high-profile applications. They are exposed to some of the most extreme stresses and harshest elements and environments. These tubulars are used for drilling and prducing oil and gas wells, then returned for cleaning, careful inspection for damages, and re-prepped for continued use. Other tubulars may be for pipelines in which the tubular may have coatings that need to be stripped and base steel prepared for use. Some applications also need to decommission old tubulars and remove contamination prior to recycling or disposing. The machines rely heavily on hydraulic cylinders from Yates. “Yates cylinders are superior in quality. They are manufactured with precision and constructed for durability. Yates also maintains a very user friendly and useful website, which allows users to custom specify and quickly obtain reliably accurate CAD models and drawings of

www.fluidpowerworld.com

any user-customized cylinders. This is a valuable tool during the design modeling and throughout the procurement process,” Thomas said. “Yates’ support and service go well with their product. You have access to expertise needed and service that you know is the best in the industry for hydraulic cylinders.” Within the Scorpion TMS, hydraulic cylinders are used to laterally load incoming dirty tubulars into the system and laterally unload the cleaned tubular out of the system usually in a production type of scale with hundreds even thousands of tubulars for certain jobs. The hydraulic cylinders are also used to actuate muffler devices, which enclose the ends of the tubulars to contain noise and flying debris during the internal/ ID cleaning process. Hydraulic cylinders are also used to precisely position the Scorpion machinery per job or application needs, as tubulars may have a variety of geometry features to accommodate. The Scorpion PRS (Pipe Rotation System) is hydraulically adjusted via hydraulic cylinders. These rollers allow for stable support of tubular as needed. Support is requires while spinning of the stationary tubular is done, often at remarkably high pipe spin speeds, from less than 1 to 1,000 rpm. This is done for cleaning the outer surface and sometimes during internal cleaning as well. When needed for bent pipe, the Scorpion TMS’ pipe clamp rollers use Yates’ hydraulic cylinders to apply clamp rollers at user-specified pressure and force onto the pipe during cleaning in order to hydraulically straighten bent pipe during spinning. This ensures smooth cleaning and is also used as needed to prevent axial walking of the tubular during some ID and some OD cleaning work. The positioning of the ID, OD, and PRS machinery for a certain job is set via hydraulic cylinders in general. “This adjustability allows

for precise, dominant and stable control of tubulars enabling Scorpion machinery to maximize effectiveness and consistency of cleaning results,” Thomas said. The system performs so well, that a major company in the industry — NOV Wellbore Technologies – Tuboscope-West Texas Div., recently purchased and commissioned into service a new Scorpion TMS at its state of the art new Tuboscope pipe inspection facility located in Odessa, Texas. The Tuboscope Scorpion TMS (Gen II) is refined and more sophisticated than its predecessor prototype in New Iberia. This second-generation Scorpion TMS is a cleaner, more compact, and safer system overall. With its significant design improvements, advanced controls and proven features incorporated througout, NOV Tuboscope’s Scorpion TMS has proven itself to be a superior new class of pipe cleaning systems and has surpassed expectations as expected, Thomas said. The NOV-Tuboscope West Texas facility is a state-of-the-art facility for cleaning, inspection, machining, and processing tubulars for the oil and gas industry. Their West Texas Facility and Scorpion TMS, gives NOV-Tuboscope unmatched superior pipe cleaning and service capabilities. FPW

DESIGN NOTES

Offline filtration loop adapters ensure clean reservoir fluids When hydraulic systems need to be cleaned, there’s no easy way to access the fluid inside reservoirs. As any user of fluid power knows, new and used hydraulic fluids typically are not pre-filtered and can be highly contaminated. One-pass filtration systems aren’t enough. Opening the filler breather cap while filling the reservoir allows airborne particles and moisture to enter. Overfilling and spills are common practice, increasing environmental pollution and the risk of personal injury. Finally, draining an overfilled reservoir is problematic and hydraulic components can be damaged by over filled reservoirs. Filtering and transferring fluid to hydraulic and lube systems is typically done by inserting tube wands through the filterbreather twist cap or threaded opening on top of the tank and the oil drum or tote bungs. This method leaves reservoirs and drums open to contaminates and spills. The (RAM) Reservoir Access Manifold from c-change offers a different, safer and cleaner solution. The RAM is an offline filtration loop adapter that allows simple access to fluids inside closed reservoirs, drums and gearboxes. With the addition of one or two internal tubes, users can add and remove fluid using the existing filter breather opening, reservoir cap, or pipe thread reservoir breather opening. Two models are available. The BD (Bolt Down) uses the standard 6-hole reservoir mount and is made of a single piece of aluminum. The DT and ST models are made of two pieces, a body and cartridge. Both have tubes that enter the interior of the reservoir and terminate below the fluid level. Both models have interconnecting passages in their bodies connecting the interior tubes to the exterior. Each has threaded ports for fitting connections “I’ve been in the fluid power industry for 40-plus years and I’ve seen firsthand how destructive dirty oil is to component life,” said Marc Watson, Founder of c-change Inc. “The Reservoir Access Manifold, or RAM, is a new hydraulic component that mounts to your reservoir, oil drums, totes and gearboxes and will save oil, components and your money.

Two models of Reservoir Access Manifolds are available, including a bolt down design and ones made of two pieces including a body and cartridge. 20

The RAM Manifold from c-change is a safe, clean offline filtration loop adapter that allows easy access to fluids inside closed reservoirs, drums and gearboxes.

“The RAM gives users easy access to the oil in reservoirs, drums and totes with no fabrication,” Watson continued. “They only take minutes to install because they use the existing reservoir breather or cap. This gives you control over what enters and leaves your system. Proactive fluid management just got easier. The RAM lets you easily use a filter cart when transferring oil from drums to reservoirs. It also allows offline filtration with your system on or off while keeping systems closed to contaminants.” The BD RAM (Bolt Down) can replace the standard filler breather and mount directly in its place. Users can remount the original bayonet cap on top of the BD or upgrade to a more efficient filter. The BD comes standard with a 1 in. female pipe thread top breather port. BD RAMs 22

incorporate five functions in one body. Features include: • Reservoir filler/ breather • 1-in. positional suction tube • ¾ in. positional return tube • Overflow port • Oil sampling port The suction and return down tubes are inserted into the bottom of the BD and can be rotated 360°. Both tubes terminate below the reservoir fluid level. They can be straight or bent and positioned in the reservoir for maximum efficiency. An overflow passage communicates with the reservoir air gap in the event of overfilling the tank. This gives the potentially over-pressurized fluid an exhaust route, without causing damage, all while minimizing spills. Oil sampling is

accomplished by using an internal flexible tube within the air breather passage which can be attached to either down tube terminating below the fluid level. Because of the stationary position, reliable oil samples may be taken with the system on or offline. Models DT and ST accomplish the same functions as the BD model, but without a separate sampling port, and attach to the reservoir differently. DT and ST use a male pipe thread or straight thread mounting connection and offer one or two internal down tubes. Overflow protection and a breather port is provided. The DT and ST models are designed to maximize the internal area by minimizing the internal male thread wall thickness. This reduces the choking effect of having down tubes inside the male attachment thread. The down tube sizes have been selected to maximize air flow while keeping the largest possible suction tube diameter. A final benefit, said Watson, is reduced oil usage. RAM users can delay oil change outs and reduce system component replacements. “You will now be able to obtain and keep those ISO cleanliness codes. RAMs facilitate the greening of our industry — finally,” Watson concluded.

Hydraulic symbology 202 — stacked and piloted industrial valves In Hydraulic Symbology 201, I discussed directional valve symbols from basic construction to valve transitions. For the most part, these symbols pertain to industrial stack valves, although cartridge valve symbology is similar. When the stack valve — aka CETOP, ISO or “D-something” valve — is drawn in a circuit, however, it looks much different. Shown below in Figure 1 is a simple circuit employing two cylinders assisted by various accessory valves. I haven’t covered the design and function of pressure, flow or check valves, so ignore them for now. What’s important to observe is the relatively linear method of drawing each subcircuit, with the pump pushing through all the valves and then eventually onto the cylinder.

no way to know, and from a design standpoint, how it is plumbed is irrelevant to the circuit drawing. A circuit made from stack valves, Figure 2, is a different animal, and you can be sure they will be plumbed as you imagine it should be. Each component of the valve stack is sandwiched together and bolted tightly into the manifold with Figure 2. tie-rods or socket head cap screws. The Stack valves manifold is always on the bottom, and the | Hengli America directional valve is nearly always fixed atop. The drawing below shows the stacked valves interfacing and separated by a boundary line, which you’ll remember is the brokendash line I explained way back in Symbology 101. Image 3 shows the same 2-position valve on the left with the 4/3 valve again on the right. Fluid enters the left side of the manifold at the P port and feeds oil equally to each valve station. This manifold has two stations, but I’ve seen up to as many as 16 stations machined into a single bar.

Figure 1. Standard circuit

The valves of this hydraulic system are plumbed together individually with hose, tube and fittings, but their physical relationship is not defined. The relief valve could be attached to the pump or it could be a room away. The directional valves could be at opposite ends of the machine and both lead to cylinders that work in tandem. There’s 24

Figure 3. Stack valve circuit

Figure 4. Hengli NG32 Valve | Hengli America

The valves are plumbed in parallel, so either sub-circuit has equal access to flow. The left-side stack uses a method of drawing the directional valve with the pressure and tank lines running through the center, with pressure on the left-center and tank on the right-center. In the neutral position, fluid travels up through the reducing valve, through a hole in the pilot-operated check valve and up through the directional valve.

Because the valve is at the top and is a 2-position valve, fluid goes straight through and back down again, where it passes through the PO check itself, down through a drilling in the reducing valve, through the manifold and out work port A. It sounds like a lot going on when you spell it out, but it’s really quite simple. Each and every component in a stack will flow fluid through one or more ports so long as the directional valve is actuated. Stack valve circuits can also be drawn as is shown in Figure 3. Here I show the pressure and tank lines side-by-side on the left with the work ports in parallel on the right. This is my preference as I find it represents the workport valves more cleanly. You can see here the flow control and dual PO check valves closely situated, where pilot lines are easily drawn. With P and T on the left, fluid travels from the manifold up through all four valves

and back down again. It can take some getting used to when valves are referenced both upwards and downwards. Any valve situated in the P or T lines will be directed upwards, but valves in the A and B work lines are drawn upside down. When stack valves are made to flow more than a D05 (NG10) is capable, a pilot operated valve must be employed. An electrical solenoid’s power isn’t enough to overcome the flow forces inside a large valve, so the spool must be moved by hydraulic energy, like a small steel cylinder rod. The pilot valve is mounted atop the mainstage spool as shown in Figure 4, but the symbol can be drawn in two ways. The first is the simplified version, Figure 5, the compound operator symbols show both pilot and solenoid operation, while the rest of the valve remains standard in its description of a 4/3 spring-centered valve. When you look at the expanded symbol below it, two valves are

more accurately describing what is seen inside the valve. A single pressure line enters the valve where it feeds both the pilot and the mainstage valve. Because this example has an internal pilot supply, it also has an orifice to limit flow entering the pilot valve. Without an orifice, the valve would be exposed to potentially hundreds of gpm when it was designed to handle just a few. The pilot valve is solenoid operated, and when shifted, sends pressurized fluid to the main stage spool, shifting it easily. In this case, both the main stage and pilot valve drain through a common tank line. However, just as pilot energy can be via external supply, so too can the pilot valve drain externally. This is always a good

TRAINING Carl Dyke • Lunchbox Sessions

Learning hydraulics on a tablet

Traditional on-site fluid power training is always a compromise. Shifts have to be scheduled around, an instructor found and brought to the site, and the class needs to learn and move forward together. If the abilities of the students in that class are badly mismatched, some students will spend most of their training time bored, wading through beginner material, while others might be overwhelmed by material that is too advanced. Even skilled instructors have to compromise, and teach towards the middle of the class’ ability. At the end of the class, the instructor vanishes, and the students resume regular work. Whatever was not absorbed in that short visit is lost.

Some businesses look to computer-based training, or e-Learning, to address these training deﬁcits, but traditional e-Learning comes up short in the ﬂuid power world as well. Many, if not most technicians, mechanics and millwrights are not thrilled at passively 28

Customer turns it off — and saves!

A leakage assessment was done at a small industrial shop and a constant flow was found in a CNC machine. This machine was very rarely used, perhaps running less than 1% of the time — however, it was consuming a significant flow for internal purging. While testing this flow, a duty cycle test was done using the compressor. During this test, the loaded versus running time was measured with a stopwatch to estimate flow. (The test is done both with and without the potential inappropriate use of compressed air to estimate the flow.) This helps estimate the flow of the usage — which might be called an “abandoned use,” because air flow is only necessary when the machine is actually operating. When this test was done, the CNC flow was determined to be only 3 cfm, enough to cost about $650 in energy per year. However, a strange thing was noticed. When this flow was “on,” the 10-hp compressor ran constantly loaded at about 10%, but running unloaded the remaining 90% of the time. When the flow was turned “off,” the compressor load reduced by about 8%, but the compressor turned fully off between load cycles. This compressor consumes about 3.5 kW while running unloaded — but produces no air and the estimated annual hours in this condition is about 7,845 in wasted operation. The loaded power consumption of this compressor cost about $745 per year, but the unloaded power consumption was costing $2,760 per year. Turning off the CNC flow saves significantly more than expected, due to the reduction in compressor run time. An automatic valve was installed on the machine to turn off the purge flow when there is no production. This is expected to save much more annually than the $300 cost of the shutoff valve. Even more savings would be gained if system storage was increased to slow down the compressor cycles. This is another example of what can be gained by simply turning off the flow of compressed air when not required!

This valve turns oﬀ a constant compressed air ﬂow when not required.

Research symposium The NFPA will present its IFPE Research Symposium March 11-13 during lunch presentations. This program showcases the latest fluid power research being performed at U.S. universities with funding provided by a new program within the U.S. Department of Energy to improve the energy efficiency of hydraulic systems on off-road vehicles. The Symposium will be held from 11:30 a.m. to 12:30 p.m. each day in room S231. Presentations include: Individual Electrohydraulic Actuators for Off Road Machines, presented by Andrea Vacca, Purdue University. The objective of the project is to propose a new technology for electrohydraulic drives for machines. The project sub-goals are to develop and test a novel electrohydraulic pump/motor, to develop a layout architecture for electrohydraulic actuators, and to demonstrate the technology on offroad construction equipment. The target is to achieve improvements in fuel economy up to 70%, depending on the drive cycle. Efficient, Compact, and Smooth Variable Propulsion Motor, presented by James Van de Ven, University of Minnesota. This work will develop a revolutionary variable displacement hydraulic motor for the propulsion drive of off-highway vehicles. The motor combines unmatched efficiency at all displacements, high displacement density, and low torque ripple. The high efficiency is a result of the mechanism using all rolling element bearings, low piston side-loads, and minimal unswept cylinder volume. The high displacement density is achieved through the radial piston packaging and a multi-lobe cam, creating multiple piston strokes per revolution. This talk will present the model driven design, optimization, and experimental testing of a prototype motor. Hybrid Hydraulic-Electric Architecture for Mobile Machines, presented by Perry Li, University of Minnesota. The project will develop a system architecture for off-road mobile machines that marries the benefits of hydraulic actuation and electric actuation to achieve both energy-saving and control performance. The proposed approach is especially useful for high power/high force machines that would be difficult to electrify directly with conventional ElectroHydraulic Actuation (EHA) technologies. The project will also investigate how best to integrate electric and hydraulic machines to achieve efficient and power energy conversion devices. AEM members interested in research and development projects of importance to the fluid power and off-road machine industries are welcome to attend. For more information, visit ifpe.com/education. Pre-registration is required to reserve one of the complimentary lunches each day.

FLUID POWER WORLD

Designing with hydraulic cylinders on mobile machinery Mobile machinery is rife with hydraulic cylinders, particularly for use on buckets, shovels, booms and other tools and attachments on machines like backhoes, excavators, telehandlers, cranes, balers, skid steer loaders, dump trucks and more. These machines and attachments use hydraulic cylinders to push, pull, lift and lower loads that other might otherwise be impossible to move with lesser force technologies. Cylinders are responsible for converting hydraulic power into linear motion to do work or move a load by applying pressure to the cylinder’s piston. These somewhat simple devices usually feature a basic construction, including the aforementioned piston inside a cylindrical or rectangular tube or body, end caps and housings, as well as necessary bolts, nuts, plugs, bearings, rod seals and wipers, and more. The two most common designs used on mobile equipment are welded-tube and tie-rod cylinders. Welded cylinders are constructed of a heavy-duty tube that is closed oﬀ with a welded-on cap. Mounting anchors, including trunnion, side lug and side tapped, clevis, bolt, and ﬂange types, are usually attached to the welded cap. A threaded gland on the rod end allows these cylinder types to be easily repaired. The simpler, but less durable tie-rod cylinder is designed with bolts and tie rods that hold two castings on each end of the barrel together. Also easy-repairable, this cylinder design is common on agriculture equipment and is often used on NFPA or ISO cylinders. To determine a cylinder’s mechanical force, one must know the diameter of the piston and use the following formula to give you the linear force of a cylinder. First, convert the piston diameter into area by using πr2 then multiply area by your chosen pressure unit.

Differential cylinders are the most common hydraulic cylinder design. Because they feature a rod in just one end, the force created when retracting is not equal to that created when extending. In retraction, a differential cylinder has less area for pressure to work upon because of the space taken up by the rod. Consequently, a differential cylinder will retract with more velocity than it extends, given equal flow at either service port. Once again, this effect is a result of the space taken up by the rod—in this case, filling up the reduced volume more quickly. The force reduction resulting from the rod location is inversely proportional to the flow increase from the same cause. For example, if the area of the cap side of the piston is twice that of the area from the rod side of the piston, it is referred to as a “two-to-one” cylinder. This cylinder will extend with twice the force than in retraction, and retract in half the time as extension. Differential cylinders are normally double-acting, i.e., they are powered in retraction as well as extension. A differential cylinder can be powered in just one direction, if required, which is called single-acting. A single-acting cylinder is manufactured in various forms, and normally when a differential cylinder is used as single acting, it will have a breather at the non-powered port to avoid trapped air. Single-acting cylinders are sometimes spring

TOUGH SWIVELS loaded, and are important if the mass of the load isn’t enough to push the ﬂuid back through valves alone. Springs can be added to either the cap or rod end of a cylinder, enabling spring-extend or spring-retract functions respectively. Single-acting cylinders can also be rams, which are cylinders consisting of just a rod in a tube. Pressure pushes the ram up or out, but often requires energy to retract. This energy can come from the mass of the load, but sometimes is generated from springs or other devices that are part of the machine itself, rather than inside the cylinder. Another common cylinder species is the telescopic variety. These cylinders use multiple-sections that are both bodies and rods, and can extend far longer than their retracted length would suggest. They are relatively compact and can usually extend twice their retracted length. Telescopic cylinders have as many as seven stages or more, providing a compact footprint with a surprisingly long stroke length. A cylinder with 120 in. of stroke only needs 50 in. of retracted space, while a traditional cylinder will always be longer than whatever its stroke length is.

Designing with fittings and couplings on mobile machinery Hydraulic fittings and couplings get taken for granted, especially with mobile machinery, where profit margin can overshadow design. The reality is that fittings and couplers are as crucial to the design of a machine as are the pumps, valves and actuators. Let’s consider what makes a hydraulic fitting functional: it must fit into the port of the component it was selected for, it must withstand system pressure without fail, and it must flow well with little pressure drop. I believe the first two factors are adhered to uniformly, but consideration to flow is sometimes ignored. Calculating pressure drop through fittings — all of them — is an essential element of fluid power machine design. Although the math may be complicated, online calculators allow you to enter

the fitting size, type and quantity to see actual pressure drop. Knowing the pressure drop is critical to design because it allows you to find the sweet spot between price and performance. If the fittings are undersized, you must subtract the energy required to overcome flow from the energy available for work. Hundreds of psi of pressure drop could reduce machine performance due to undersized fittings or excessive connections and elbows. Should fittings be oversized to prevent flow restriction, you may be increasing cost and bulk. As fittings increase in size, their price may rise exponentially, so forethought results in the correct size, price and flow rate for your design. Myriad options are available for thread and sealing types. Let’s start by dismissing NPT thread altogether. NPT fittings require so much extra work and effort to install, and when you factor their inferior performance, there is no excuse to use them. Fittings, whenever possible, should only use soft-sealing technology, like O-ring boss (in the form of SAE, BSPP or metric straight thread) fittings. O-rings provide a positive seal with little chance for leakage and are easy to ensure a tight, leak-free connection. For hose connections, JIC fittings have suited the world well up to this point but are now supplanted by O-ring face fittings, which provide a superior connection. Of course, the price also plays a part in fitting design, and O-ring fittings do cost more, so one must balance price with performance once again when designing with fittings and couplings. FPW

Designing with hydraulic hose on mobile machinery Because it is impossible to physically stack every component of a hydraulic system like a Jenga tower, plumbing is required to direct hydraulic energy through the circuit. Pipe, tube and hose are required to channel fluid through the system, and the requirements of the system must be reflected in the choice of conduit. Hydraulic hose is the most commonly used conduit, especially on mobile machinery, and is mandatory should any bending or movement in the mechanism require it. Hoses feature a multi-layer construction, most often with synthetic rubber such as Nitrile and strengthened with braided steel, although synthetic and textile braids are used as well. The pressure rating of hydraulic hose is a result of the number of braid layers and the nature of their construction. The SAE has created standards for hose construction, which dictate specifications for pressure, temperature and type of fluid being used. As you would imagine, the more layers of braided material used, the higher the pressure the hose can

withstand. Consequently, hose with four or six layers of steel braiding is quite stiff, so consideration should be taken for bendradius requirements when choosing hose. Consideration should be taken for diameter when selecting hose to ensure pressure drop remains in check; pressure drop is so often overlooked in a hydraulic system, and the energy wasted can be extensive. However, just as the layering of braids can affect the rigidity of hose, so too can its diameter. Hose manufacturers publish the bend-radius of their hose, and most manufacturers carry a short bendradius hose in their product line, although it is often more expensive. Specialty hose is available for demanding applications, such as for use in high heat or with exotic fluids. Steel braiding in a hose transmitting high water-based fluid is bad news, as internal corrosion will occur and will go unnoticed. Hose can also be had with non-conductive construction, to ensure the hose does not transmit electricity when installed on a machine working on electrical utility jobs. The most common hydraulic hose is the 100R1 and 100R2 construction types, with one or two layers of braided steel respectively. These hose types are not suitable for every application, so consult with industry professionals when choosing your hydraulic hose. FPW

Designing with filters on mobile machinery Contamination often enters a machine during startup, when particles from machine operations — be they metal shavings or sawdust or plastic bits — enter hoses, actuators, reservoirs and manifold ports. These particles can also flood a system during maintenance, if proper preventions aren’t taken, or during a complete machine failure. To prevent them from entering a system, use one of three main types of filters. The first, the suction filter, is mounted in the reservoir and attached to the suction line to protect downstream components, such as the pump. They are meant to catch coarse, large particles, so are not effective in trapping the major culprits of wear — fine particles. These mesh steel filters are often not included in a system’s filtration design, as they can cause clogging and pump cavitation. Next up is the pressure filter, which is installed in the pressure line, downstream of pumps and system circuits when fine filtration is required. This traps particles in fluid as it flows from the pump, so protects components downstream of the pump. You must select a pressure filter that matches the system pressure you’ll be operating in, but they are generally available in wide ranges up to and higher than 10,000 psi. The most common type of filter is the return line filter, which traps very fine particles before the fluid reenters the reservoir. Spin-on filter and in-tank drop-in assemblies are the most popular. Spin-on filters are used heavily on mobile equipment. They are rated for most fluid types and a range of pressures and temperatures. They are available in glass, cellulose fibers and paper media. Water-absorbing medias also remove freestanding water from oil. Growing in use in the mobile market are in-tank return filters. They use stronger filter media, such as synthetic and natural fibers and stainless steel wire mesh. Constructed of steel, 58

A reliable and efficient hydraulic system starts with the fluid. Keeping hydraulic oil conditioned and free of contaminants, air, water and heat is critical to ensuring that all system components run as they are meant to. To ensure this dependability, proper fluid filtration is required and should be taken with great care.

aluminum or plastic, they are suitable for heavy-duty applications. And because they are located in the filter stream, they can remove most fine particles throughout the rest of the system, ensuring clean fluid enters the reservoir. When selecting a filter you need to know what size particles it is rated to remove in one pass through. You must also know its efficiency or Beta ratio (the ratio of particles upstream of the filter to downstream of the filter during standardized testing). For example, we know how efficient a filter was at removing 10-micron particles in a single pass, such as 99%. In this case, “10 micron at Beta 200,” means the filter is 99.5% efficient at removing 10-micron particles in one pass. The lower the micron rating and higher the efficiency rating the better. Other considerations include pressure drop, flow rate and size, and obviously, price. If sized improperly, filters can break, releasing all the collected contaminants back into the system.

Designing with hydraulic pumps on mobile machinery Hydraulic systems are made of many components, but you couldn’t get very far without a pump to achieve the work. The hydraulic pump is the heart of any mobile machine, converting mechanical energy to hydraulic energy, and then pumping it out into the system. Pump design and construction can vary vastly. The choice in pump construction can often be decided by the operating pressure, as a piston pump will be more reliable at 5,000 psi than, say, a vane pump. Once pump design is ﬁnalized, you will need to choose the physical displacement of the pump, which is the ﬂuid volume it can pump in a single rotation, normally expressed in cm3/min or in.3/min.

Some pump designs are better suited for certain applications more than others. The three main types of pump are gear, vane and piston. The gear pump family has two siblings; the outside and | Courtesy of inside type. The outside gear pump Parker Hannifin is most used, because it is effective, reliable and extremely inexpensive. It uses meshed spur gears, with one driven and one idle, and is as basic as a pump can get. Gear pumps are used in every conceivable application, especially where price is a concern. Inside gear pumps use an inside gear arrangement, with more complicated construction and tighter tolerances. They are highly efficient and quiet, but can cost ten times as much as outside gear types. Regardless, they are the number one choice for some fixed-pump applications, such as servomotor driven closed-loop pump systems. Vane pumps, once one of the most popular choices, use a rotating group with rectangular vanes pushed out via springs, centrifugal force or hydraulic pressure. The offset between the vanes and cam ring allows the pump to create flow, and in variable displacement vane pumps, the offset distance is what dictates volume. Vane pumps are quiet, reliable and easy to repair. They are most popular in industrial applications, especially those running lower pressure. Piston pumps are used in most high-pressure applications. The lion’s share of the market is the variable-displacement, axialpiston pump, with the remaining piston designs claiming a small slice of the pie. This pump is highly efficient, reliable and relatively easy to rebuild although not very inexpensive. They are available with countless control options, such as pressure-compensated, load sensing, remote pressure control, proportional control, etc. The vast majority of closed loop pumps are axial piston type because it offers versatility and robust construction.

Designing with HPUs for mobile machinery Mobile machinery design has its challenges, but it has many benefits as well. A hydraulic pump need not mount near a hydraulic reservoir, and in fact, could be many feet away. A pump may be near the transmission of the vehicle or at a PTO shaft near the truck’s front bumper. As well, valves and components often find themselves mounted where it most makes sense for performance and function. These freedoms are rarely enjoyed with industrial hydraulics, where the power unit and major components are centralized. Hydraulic power units are used in mobile machinery, of course, and are not limited to industrial environments. A mobile hydraulic power unit is very similar to its industrial kin, but with various unique design considerations. Often mounted to the bed of a heavy vehicle (or trailer), it’s obvious a mobile hydraulic power unit is mounted out in free air and exposed to the worst of the outdoor environment. A power unit design must encompass corrosion resistance first and foremost, using a combination of stainless steel, composites and rust-resistant paints.

A corollary to rust resistance is the water-resistant nature of the electrical components, such as valve coils, sensors and engine control components. Electrical connections and interfaces must resist water-related damage, so, typically, advanced connection technology is used, such as Deutsch or Metri-Pak connections. These connection styles are available in a wide range of sizes and pin-counts while allowing for up to IP69K water protection, which can resist high-pressure hot water spray. Just as the outdoors can be wet, the subjection to temperature extremes requires thought as well. A diesel engine has its own heat dissipation requirements, so care must be taken to prevent exhaust heat from contaminating hydraulic oil (yes, heat is a form of contamination). Mounting a hydraulic reservoir near the diesel exhaust is a recipe for disaster, especially when the summer heat is already straining the hydraulic power unit. Very few mobile machines make do with no hydraulic cooler. Hydraulic liquid-to-air coolers for mobile hydraulic power units are some of the largest available. Having to deal with ambient heat on top of everyday ineﬃciencies and pressure drop necessitates high-power cooling. 12-volt fans are sometimes unable to keep up, so occasionally hydraulic motors are used to power fans, yielding tornado-like air power to help dissipate heat. Mobile equipment must be powerful, reliable and economical, but often only two of those criteria are considered. Although any hydraulic power unit exists to transmit hydraulic energy to perform work, the unique mobile operating environment makes designing for mobile hydraulic power units a challenge. FPW

Designing with hydraulic valves on mobile machinery

Hydraulic valves govern direction, pressure and flow of hydraulic fluid, enabling smooth, safe and controlled use of actuators. They can be as simple as a relief valve to protect your pump and actuator. Or, their use can be complex, like when using a dozen valves in manifolds, such as a pilot operated valve with dual counterbalance valves, dual flow controls, dual postcompensation and load sensing checks. The directional control valve’s function is to control the path of fluid flow. The most basic design is the check valve; it allows flow into one work port, and blocks flow from coming back through the opposite work port. They can also be as advanced as pilot operated proportional valves with internal pilots, drains and load sense check valves. Directional valves are often described as the number of “ways” fluid can travel through itself, and also by the positions available to be shifted into. The ways are equal to the number of work ports, so a 4-way valve will have pressure, tank, and A and B work ports. Positions are equal to the number of positional envelopes. For example, one would describe a double acting single-monoblock valve as “4-way, 3-position,” or simply a “4/3 valve.” 64

Monoblock or sectional directional valves are common to the mobile-hydraulic industry, as well as subplate mounted industrial type valves such as ISO style D03s, D05s, et al. Also common to mobile and industrial markets are cartridge valves installed into manifold blocks. Cartridge valve manufacturers offer many unique products, and allow high levels of creativity with limitless available valve combinations. Pressure valves are designed to in some way limit pressure. Most designs are based on a poppet being pushed against a seat with an adjustable spring. A relief valve controls maximum pressure for the entire system or a sub-circuit of it, the lowest spring pressure being the first to open up. Other pressure valves are based on the relief valve’s simple spring-loaded ball or poppet. Sequence valves, counterbalance valves, and brake valves offer added utility or functionality, such as reverse flow checks or pilot operation built in. Pressure-reducing valves differ from other pressure valves because they limit pressure downstream, rather than upstream. They are used where sub-circuit pressures need to be lower, without sacrificing performance in the rest of the system. Flow control valves are designed to control or limit flow in one way or another. Often simply a needle valve — which is just a variable restriction — it is adjusted by a screw or knob to limit energy potential to create flow. When installed with reverse flow check valves, we change the name to flow control. Flow control valves can have multiple ports, such as with a priority flow control. They can provide controlled, fixed flow to one part of the circuit, sometimes at the sacrifice of another part, and as long as input flow is high enough for its priority demand. Flow controls are ideally pressure compensated, which allows them to maintain set flow regardless of load-induced pressure variances. Pressure compensators are a type of flow control valve available as a single item, often added to other valves in a circuit to provide the same flow setting load-independent accuracy, such as with a proportional valve, for example.

Designing with manifolds on mobile machinery When designing manifolds for mobile machinery, one can quickly become overwhelmed with the volume of cartridge valve options available for installation into machined aluminum or steel blocks. Valve manufacturers offer hundreds of directional, pressure and flow control valves, often only separated by slight differences, such as an orifice. Partnering with a local fluid power company is your best bet to take advantage of a cartridge valve manufacturer’s components library. These companies are trained and have appropriate resources to help them bring your manifold to life. Many manufacturers have proprietary design software that includes their entire valve library in a light-CAD format. The highly-trained distributor drags symbols into the digital workspace, arranges them to match the desired function and then uses that design as the basis for the physical manifold. Designing manifold circuits for mobile machinery is quite rewarding. The level of creativity and ingenuity possible when creating circuits is highly satisfying. Unique valves such as a load-sensing logic element bring distinct performance options ordinarily tricky in the industrial realm. Imagine monitoring downstream pressure via a load-sense network to feed pressure to an automatically regulating logic element. This type of unique valve enables a fixed flow system to operate as if it was powered by a load-sensing pump, providing on-demand flow and pressure matching what the actuators require. Aside from the infinite combination of valves to produce any imaginable hydraulic function, manifolds provide creative spacesaving solutions. Compared to stacked valve systems, which are bulky and limiting, you design manifolds with only the material required for the job. Reduced plumbing is especially important. Rather than the pressure and tank end ports and single plane work ports of a bar manifold, you can mount the valves and ports of a custom manifold nearly anywhere you wish, as best suits the design. Although single manifold prices can be rather expensive – much engineering time goes into these after all – a custom hydraulic manifold when produced in the hundreds is the least expensive method of circuit creation. Cartridge valves are inexpensive by their nature, and when design and setup costs spread across hundreds of blocks, these manifolds are shockingly cheap. FPW

operating pressure. Additionally, a hydraulic motor’s horsepower output is a factor of torque and speed (generally described in rpm). Each motor type excels in a few applications, but could function as a compromise in others. Orbital motors go by such monikers as lowspeed/high-torque (LSHT), gerotor, geroller, and disc valve, to name a few. The last three are different configurations of the same type of motor — however, their general function is the same, by using an offset shaft inside-gear arrangement, with either a spool or disc valve. Orbital motors are the least efficient type, but excel at low-speed, high-torque applications, and are also economical. They are found on the majority of farm-duty applications, such as conveyors or spreaders, and every application where price is the major consideration. Gear motors are simple, using the same drive- and idle-gear layout as gear pumps, and although they are not any more efficient than orbital motors for the most part, they are inexpensive and work well at higher speeds. They are most often used when such a combination is required, such as cooling fan drives or pump drives. Vane motors are the least common of the major types, but are respectable in their efficiency and speed output. They can also be had in large displacements, making them a good choice for high torque applications. They use a rotor with fixed vanes, just as vane pumps, although some manufacturers use a more complicated design with vanes on the housing as well. They can be seen in winches or drill rigs. Piston motors are hard to beat in their output and efficiency. The bent-axis piston motor is the champion of high-speed operation, and can do so with huge amounts of pressure and torque. Their bent-axis design also makes them reliable, able to handle 5,000-6,000 psi long term. They’re used in any application where ultra-high speed and torque are required, such as grinders or vacuum pump drives. They’re not cheap, but they are unmatched in their power density. The radial piston motor is the torque king of the hydraulic motor empire, not only available in gigantic displacements, but also extremely efficient in creating that torque. They’re not as fast as bent-axis motors, but are the top choice for wheel drives or other direct-drive high torque applications. It should be noted that while no piston-type motor can be called inexpensive, they at least provide unparalleled performance at any price. FPW

Designing with pressure transducers on mobile machinery

Pressure measurement used to be done primarily with Bourdon tube pressure gauges, and if you wanted to check the pressure at any location in a fluid power circuit, you had to go right to the source to install a pressure gauge at the location you wished to measure. The invention of test points and micro-bore hoses allowed for some distance between point of measure and point of reading, but reliable and accurate readings were still limited. The proliferation of electronics into fluid power has changed the way we can measure pressure, and has enabled versatility not enjoyed previously. Pressure transducers are solid state, meaning there are no mechanical moving parts, instead using something called a strain gauge which changes in resistance when warped out of shape by pressure. Their solid-state nature means they are very reliable, often lasting millions of cycles. Pressure transducers require a power source to give their output signal, usually a 24-V input. Their outputs are typically one of the standard control signals, such as 0-10 V or 4-20 mA, et al. This signal can be fed into a PLC for feedback of closed-loop control, such as servo-pump pressure control, or the transducer signal can simply plug into a digital display. Transducers are typically male-threaded and plumbed into any location where you wish to measure pressure. When used in conjunction with a PLC, the basic plug-in type with a M12 or DIN connector is all that is needed. The transducer must be chosen for the appropriate pressure range it will measure, especially if you wish it to be accurate. For example, if you are measuring around 100 psi with a 0-10 V transducer, using a 1,000-psi transducer will only ever read 1 V, leaving the rest of the pressure range unused. Pressure transducers are also available with on-board electronics, including displays and switches. One device, for example, can display the pressure, provide a handful of switch’s outputs with configurable switch-back points, and also provide its analog output for a PLC to use as well. With the cost of electronics at an all-time low, they’re not as expensive as you would think, either. FPW

seals and piston seals. They are most often cup-shaped to take advantage of pressure to increase sealing. Static seals, such as O-rings or gaskets, are used to separate two areas of a component, such as a reservoir lid or spool valve end covers. Seal construction has come a long way, the majority of which is now of synthetic construction — Viton, Buna N or Teflon, to name a few. Seal composition needs to reflect the fluid used. Buna is fine for mineral oil, but Viton is required for exotic fluids such as glycols or esters. The shape of the seal is usually dictated by the location of its use. A piston seal typically has the cross-section appearance of a “U.” As you can imagine, pressure inside the middle of the U pushes the edges outward, with extra pressure creating extra sealing. The traditional O-ring is still very common. Although less common these days in dynamic or high-pressure applications, it can still be found in countless applications, such as pump rear-covers or ISO valve mounting. Most high pressure O-ring applications used for static pressure holding require a back-up washer, typically made of Teflon, which prevents the O-ring from being extruded out the lower pressure side. Nearly every cartridge valve, for example, uses the O-ring/back-up washer configuration. Seals are typically measured by their cross section width, their ID and their OD. Metric and SAE sizes are both common, and although component manufacturers offer rebuild kits with a complete set of seals (for cylinders, pumps, etc.), any competent technician can quickly measure up seals to be purchased through third-party sources.

The machine’s batteries store enough energy to power the ECR25 and L25 for eight-hour shifts in common applications, such as utility work and light infrastructure and agriculture tasks. Onboard chargers enable overnight charging via a regular household plug socket. A fast-charging option, requiring more powerful grid access, will also be offered.

Combining zero emissions, low noise and a width of just 28 in., the battery-powered, zero tail swing (ZTS) E10e can easily pass through standard doors and in and out of lifts. The E10e is based on the dieselpowered E10 ZTS mini-excavator, with the same profile, identical external dimensions, and equal or better performance. The electrohydraulic powertrain system fully uses the electric motor capabilities. It is equipped with auxiliary lines and an efficient oil cooler system for continuous hydraulic breaker operation. The machine also accommodates hydraulic pilot-pressure controlled joysticks. And it offers extremely quiet operation on site at only 71 dBA vs. 80 dBA for the standard E10.

The electric drive powers a load-sensing hydraulic system (LUVD) that oﬀers smooth operation and excellent performance

when using multiple functions at operating pressure to about 3,500 psi. Its lithium-ion battery can be charged at a household socket or at a mains power connection (express charging process), which increases the machine’s running time over an entire workday. The machine also maintains its weight class, inclusive of the battery, and can thus be transported on a car trailer. Production of the EZ17e began in late 2019.

This improves operating performance and reduces energy consumption. The hydraulic system is electrically driven using standard components.

The BEVs reportedly have peak power output double that of a conventional machine. This lets the electric earthmovers accelerate and work faster, and increase productivity by 10% compared to that of diesel versions. Batteries are designed to last the life of the machine and the electric systems eliminate daily maintenance and regular service of the engine, saving time, materials and money. The first-generation BEV batteries are equipped with fast-charging technology, which need only one hour to charge the battery to 80% full and maintain uptime. All three models are designed based on a common platform among parts and systems. This simplification will help lower the total cost of ownership. Officials said total operating cost of a battery-powered earthmover is, or soon will be, lower than that of a dieselpowered machine, depending on the customer application.

Kubota’s KC70-4e electric mini-crawler dumper features an electric transmission and has a 1,550 lb load capacity.

Mecalac’s e12 is the electric version of the company’s 12MTX excavator. With diesels slated to be banned from certain construction zones, it’s designed for urban building sites that are ever-more compact, high-performance and environmentally friendly. An articulated chassis lets it move easily around obstacles and terrain. The e12 incorporates iron-phosphate (LiFePO4) battery technology that offers three times as many lifetime charge cycles as classic batteries, reportedly with complete safety — the components pose no risk of fires or fluid leaks. Moreover, the batteries offer a capacity of 146 kWh, which results in an unrivalled range of eight hours even in demanding conditions, and eight hours to recharge. It has two independent electric motors powering the two main hydraulic circuits, one for operating excavation functions and one for travel. The electric transmission is said to offer best-in-class tractive force and brake-energy regeneration.

diesel counterpart. Eliminating the engine also substantially reduces vibration, improving the operator environment. The 19C-1E includes a Bosch Rexroth loadsensing hydraulic system for excellent digging performance and bucket tear-out. The high efficiency electric-hydraulic system also lowers cooling requirements — only a small hydraulic cooler with a thermostatic electric fan and no engine radiator are needed — and contributes to longer battery life and less noise. Three lithium-ion batteries store 15 kWh of capacity, enough to power through a typical workday on a single charge. An optional fourbattery pack increases capacity to 20 kWh and delivers an additional two hours of continuous use. Recharge time with standard 110 V input is 12 hr; available 230-V option is 8 hr; and the fast-charge option gives a 2-hr recharge. JCB research indicates that electric charging costs for the 19C-1E will be 50% lower than fuel costs for a comparable diesel-powered machine over a five-year ownership period. Similarly, with fewer consumable spare parts and fluids, servicing costs could be 70% lower.

Hyundai/Cummins

The 19C-1E is JCB’s first fully electric miniexcavator offered in North America. It is part of the company’s E-TEC family, a new generation of electric products with zero exhaust emissions, greatly reduced noise and no compromise on performance. The 2-ton model offers the same power and more torque versus comparable diesel-powered machines. And at 7 dBA lower, it generates one-fifth the noise of its

Cummins and Hyundai Construction Equipment have jointly developed an electric-powered mini-excavator. The collaboration reportedly combines the strengths of Hyundai CE’s versatile excavator design with Cummins’ lithium-ion battery technology and machine integration expertise. Powered by Cummins BM4.4E flexible battery modules (4.4 kWh each), the 3.5-ton excavator is designed to operate for a full

eight-hour shift and charge in under three hours. The machine eliminates all gaseous and particulate emissions and substantially reduces noise, making it ideal for use in urban and suburban construction. The excavator contains eight BM4.4E modules connected in series to provide a total storage capacity of 35.2 kWh. Mounted in the base of the excavator, the modules combine high energy density and proprietary control technology to maintain the battery state-of-charge for a longer operating range. A modular design lets the system be built up and aligned to the duty cycle of the excavator. The goal is to design electrified products that match or exceed the reliability and performance of their diesel counterparts. The prototype machine is being tested to optimize performance, prove the structural integrity and enhance marketability. Kobelco

Kobelco displayed a 1.7-ton electric miniexcavator concept at last year’s bauma exhibition. The unit builds on previous developments in hybrid and electric technologies, such as the iNDr (Integrated Noise and Dust Reduction Cooling System) and innovative high-efficiency hydraulic systems. The 17SR unit reportedly combines Kobelco’s expertise in developing efficient construction machinery for urban jobsites with Deutz’s electric-drive technology. The objective is to manufacture a fully-electric mini excavator that will perform at the top of its class and deliver zero emissions, extremely low noise operation, reduced lifecycle costs and long battery life. Kobelco expects to launch the 17SR in 2021. The company’s long-term objective is to further expand its machinery line-up to include more electric-driven excavators and help promote a sustainable society. Komatsu

Komatsu fork-lift and hybrid technology, the only difference is that the hydraulics are driven by electric motors. The circuits include two variable-displacement piston pumps producing 18.3 gpm for boom, arm, bucket and travel operations; and two gear pumps for swing and blade functions with flows up to 5 gpm. The systems are rated in the 3,000 psi range. Variable-displacement piston motors are integral for the hydrostatic travel drive, and fixed-displacement piston motors for swing. With a power rating of 18.5 kW, the machine has the same rating as the diesel version. Performance is the same in terms of digging power and speed, and it operates virtually without discernable noise. However, it does have better stability as it weighs a bit more. In light to medium-duty application conditions it will work for up to six hours. In extreme conditions, it may need recharging in as little as 2.5 hours. With standard power, it recharges overnight; a fast-charging system permits recharging in an hour. The prototype machine is currently on test at customer sites in Japan.

DMIC DMIC is a Buffalo, NY based company that provides Hydraulic components such as Ball Valves, Flow Controls, and SSW components to a variety of industries that include, but not limited to, Petrochemical, Mining, Marine, Industrial, and Aerospace applications. Since the early 80’s, DMIC has consistently valued Punctuality, Consistency, Stability, and Continuous Improvements.

The DMIC Engineering team is a dynamic powerhouse, a group assembled to enhance and support the needs of our customers. The DMIC Engineering team works with customers to help identify the needs, review the requirements, sure up the documentation, verify the fitment and deliver the product. A DMIC Engineer is not just a person with a degree, but a full project manager with skills that cover all aspects from design and development, time management to manufacturing support. Sometimes, it’s the details that go unnoticed – designs with a level of refinement only expected from a master machinist, to improve throughput and reduce the cost; but still verified with Finite Element Analysis (FEA) and Computational Fluid Dynamics (CFD) to ensure functionality and ultimately, customer satisfaction. Easy to talk to, understanding and technical, from your first dealing you will notice the difference compared to the impersonal, uninformed ‘big box store’ hydraulics manufacturer.

DMIC is a privately owned corporation that is proud to be a family oriented work force with very low turnover. With our proud work force, we have grown to creating original, stable, superior products, and manufacturing those products in a mindset that eschews cost-cutting compromises, low performance and cheapness. For more information on DMIC, please call 1-800-248-3642 or visit www.DMIC.com

With these traits, DMIC Engineering is a leader in hydraulic component design, a delicate balance of “right parts for the job” with “when I need it”. Building off our culture of high quality and proven product lines, the DMIC Engineering team is always willing to go above and beyond, at the desk or onsite delivering the solutions that make industry work.

AVENTICS Sentronic PLUS and Sentronic LP Proportional Valves with IO-Link capabilities

The Sentronic Plus and Sentronic Low Power (LP) ranges of proportional valves enable process optimization, regardless of application requirements. Sentronic Plus digitally operated pressure regulator valves accurately adjust pressure, ﬂow, force, speed and linear or angular positions. They regulate pressure up to 174 psi (12 bar). The Sentronic LP valves are a highly efﬁcient option for pressure regulation requirements, offering a small footprint, an easyto-use and modular design, and advanced software capabilities. Their lowpower consumption of less than four watts supports applications where power is limited. IO-Link is applied to a range of automation applications, providing a cost-effective digital communication interface for sensors, actuators and controllers via unshielded, industry-standard M12 I/O cables. Adding IO-Link capability to these proportional valves not only makes the devices easier to control and operate, but also prepares them for future integration with IIoT applications, enabling improvements in plant reliability and availability.

Zoned safety helps to improve productivity and machine availability because users no longer have to shut down the entire machine when safety circuits are enabled. The AVENTICS Series 500 valve systems can integrate multiple safety zones within a single valve system. Emerson´s Zoned Safety solution goes beyond the standard release of energy, or “dumping of air” practice by proving that predictable motion can be safe. It allows isolation of the air supply to keep operators safe without unnecessary disruption to production. This simple, user-friendly solution helps the design engineer satisfy the Machinery Directive 2006/42/EC and comply with ISO 13849-1 while eliminating the components and complexity commonly found in existing safety circuits.

What makes mobile hydraulics different from industrial?

The need for lower weight, size and costs mean that mobile machinery often sets the stage for power density improvements in fluid power. Josh Cosford • Contributing Editor

All hydraulic machinery should be similar in scope and design, one would think. After all, the point of fluid power is to transmit force. Why should any given mobile machine be vastly different in its execution

force, can’t this be achieved with the same pumps, the same valves and the same actuators?

My question is naïve, of course. Machinery is different for many reasons, not the least of which are the preferences of the engineer(s) designing them. Mobile machinery works within broad environmental conditions and with specific design limitations, both of which are not handicaps for industrial machinery, which is freer to “be itself” as it were. Mobile demands lower costs

The industrial hydraulic environment enjoys liberties not available to the mobile machinery camp. The most obvious of which are space and budget. Although not necessarily unlimited, hydraulic power units are bespoke designs naturally requiring individual attention for each build, so we understand the cost is often high. The same, too, with available real estate; both the power unit and actuators often have no dimensional limitations with floor or installation space. Mass, of course, is entirely irrelevant on industrial hydraulic machinery, as is evident if you’ve ever seen an automotive stamping press. The mobile hydraulic machinery industry is a shallow-margin, competitive business with strict cost control, even though some individual machines may cost more than entire industrial manufacturing plants. High volume machinery, such as excavators, loaders and aerial lifts, etc. are manufactured in the thousands. Because dozens of companies make these machines in volume, the cost of every component from hex nut to closedloop pump is at the low end for its segment. It’s not to say manufacturers choose economy grade hydraulic components across the board, because some applications absolutely require highly engineered, robust and reliable pumps, valves and actuators. It’s that component suppliers live with slim profit margins as a penalty for being the supplier of choice for the application. If a skid steel loader manufacturer is shipping a thousand units a quarter, all using the same spin-on filter assembly, you can bet they’re paying a fraction of the retail price an end-user would. However, industrial hydraulics do not operate in a cost-is-no-object environment, but the industrial customer prizes reliability, quietness and efficiency more often than does the mobile domain. So even if the closed-loop drive on a front-end loader uses the most advanced hydraulics on the planet, it doesn’t mean your 110

logsplitter manufacturer is subject to the same requirements. The logsplitter is a mobile hydraulic example where cost is absolutely the most critical factor in the purchasing decision, so long as the part does its job. Weight, size limitations

Mass is a paramount concern for most mobile machinery, and often concomitantly considered alongside cost. Counterintuitively, reduction in mass is more expensive, not less. The easy solution to machine design is to throw thick plates of steel everywhere you can to ensure your machine is strong enough to handle its functional purpose reliably. Compared to the alternative, steel is cheap. The alternatives are expensive: advanced computer design with models and simulations, exotic and lightweight materials, and electrification to replace mechanical or hydraulic components. Weight reduced from the components of a machine can be added to maximum load capacity, especially if Gross Vehicle Weight regulations are part of the equation. Consider power density and its relationship with hydraulic machines. Herein lies what is the primary differentiating factor in setting mobile

hydraulics apart from its industrial cousin. Power density is why hydraulics remain relevant to mobile machinery. Power density is defined as the power output capacity as a ratio of actuator size. Nothing can touch the power density of hydraulic actuators, and it’s likely nothing ever will. The wheel drive motors on a modern bulldozer, for example, operate at more than 6,000 psi – double the standard for industrial hydraulics. Imagine a 300 hp (220 kW) drive motor weighing only 260 lb (120 kg). If you think 260 lb seems like much mass, consider that a 300-hp, 1,800 rpm industrial electric motor weighs … 3,000 lbs (1,360 kg). Mind you, that same hydraulic motor exists for industrial hydraulic applications, like the screw motor on an injection molding machine. However, that screw motor is unlikely to run at greater than 6,000 psi. While we’re on power density and hydraulic motors, I like to throw in a shameless plug whenever I can. If you think the above radial piston drive motor example is impressive, let me introduce you to bent-axis piston motors. This motor has a unique fixed swashplate angle and heavyduty bearing combination that facilitates high speed operation at close to 6,000 psi, in many examples. The tiny Bosch Rexroth

A2F5 motor (just 5 cc of displacement) spins dizzyingly to the tune of 35 hp (26 kW), weighing only 5.5 lb (2.5 kg) and fitting into your venti blonde espresso cup. So, the power density of hydraulics frees up mass in mobile machinery, whether that mass supplants load carrying capacity or not. In this era, likely the mass reduction helps the machine meet strict emissions standards and to downside the power unit, which is, at times, the most expensive single purchase for the machine. Making do with less than 175 hp (130 Kw) when the earlier machine required 200 hp or more, means the diesel engine and all its cumbersome emissions-related components enjoy downsizing. Controls are night and day

Where mobile and industrial hydraulics differ nearly without exception is on the control side. Both are regulated using entirely different components, circuits and logic. It starts with the basic through-center directional control valve used with fixed displacement pumps. Through-center is similar to a tandem center industrial valve, where pressure can flow from inlet to tank when the valve is unshifted in neutral. Industrial tandem center valves are limited in their flow capacity because fluid

travels through the spool itself in neutral with high pressure drop. Through-center valves have an entirely separate core, called the through-center core, in addition to the power core and tank core. The throughcenter core for a single spool valve simply exits to the tank. However, if you add a power beyond adapter, the through-center core separates from the tank core, and all fluid passes downstream when the valve is in neutral. This allows auxiliary downstream functions. Large, multi-spool sectional and monoblock valves also use this construction, but share passageways within their very construction, omitting the requirement for a power beyond adapter. Industrial applications use mostly stacked valves or custom integrated manifold circuits. However, although mobile applications commonly use integrated circuits as well, advanced sectional valves with custom functionality are standard practice for heavy-duty machinery. They are optioned for either fixed or variable displacement pumps and come prepped with drillings and ports for accessory valves. Port relief or counterbalance valves are frequent additions, and if unused, you close off the passages with a cavity plug. A control tactic common in mobile hydraulics I’ve never seen in the industrial market is load sensing. Load sensing is a control concept that measures downstream pressure close to the actuator to compare load pressure and flow-induced pressure drop. This load sense signal feeds back to the pump, which interprets the signal and provides only enough flow and pressure to satisfy the demand of any currently operating valve. The load sense pressure drop is typically only a few hundred psi, providing efficient operation for applications using a diverse set of actuators. I believe as technology advances, mobile and industrial hydraulic design trends will continue to evolve separately, but in parallel. Power density in mobile applications continues to rise, and efficiency placed at the forefront will ensure reduced carbon footprint and increased productivity. FPW

A disruptive sensor for

intelligent hydraulics The LiView is an innovative position transducer for hydraulic cylinders that uses the piston itself as a sensing element. Alexander Bertsch • Head of Product Line Sensor Technology Liebherr Elektronik GmbH | Lindau, Germany The adoption of electronic controls into mobile equipment has led to game-changing productivity enhancements — precision excavating and grading, remote maintenance capabilities and autonomous machine operation, just to name a few. But for such systems to operate seamlessly, the sensors in components like hydraulic cylinders must supply data that are precise and reliable. Modern measurement systems in mobile machinery face daunting challenges like severe vibration and extreme temperatures. Based on extensive know-how with demanding operating conditions, Liebherr has developed LiView, an innovative stroke transducer for hydraulic cylinders that uses the piston itself as a robust sensing element. The new measurement concept can be easily integrated into cylinders large and small, is universally applicable and rugged and reliable. It is particularly advantageous in heavy-duty applications because no moving parts that serve as sensing elements are installed inside or outside the cylinder. System basics

LiView technology measures the physical state of a hydraulic cylinder by making real-time electrical measurements of its mechanical structure to determine cylinder position and velocity. The basic conﬁguration involves two probes mounted in the piston rod bearing that are connected to an electronics module via a 114

conventional coaxial cable. Each measuring cycle, the electronics generates a predefined high-frequency electromagnetic signal that the probe at one port injects into the cylinder structure. The transmitted signal propagates to the piston, where it is reflected back and intercepted at the second probe port. This analog signal is digitized in the electronics and processed to calculate position. The working principle is based on viewing the cylinder as a multi-port electrical system that can be thoroughly characterized by means of its of scattering parameters — a technique that is used in high-frequency electronics for circuit characterization. The two probes, termed port 1 and 2, are used for injecting a stimulus at a given frequency and simultaneously receiving the cylinder response. From an electrical point of view, the system is fully described by a 3 × 3 scattering matrix, which defines the relationship between injected and reflected electromagnetic waves at either of the two ports. The transmission factor between port 1 and port 2 relates to the impedance of the cylinder tube that can be modelled as a transmission line. Piston position defines the length of this transmission line, producing a direct relationship between the phase of the electrical signal and position information. Liebherr engineers have developed a mathematical model that precisely describes the electrical response of the hydraulic cylinder.

It’s used to transform the measured scattering parameters and calculate absolute piston position. This makes LiView an absolute stroke transducer, allowing the calculation of position at each new measurement cycle and without requiring starting-position information. LiView components

As mentioned above, LiView constituent parts include the electronics unit and two probes. It also has a high-frequency passive element that operates as a guard ring isolating the cylinder cavity from the external environment. The guard ring ensures a stable boundary condition for electrical measurements. The LiView Electronics Module (LEM) mounts either on the cylinder or on the surrounding structure, depending on application constraints. The only caveat is that cable length should be limited to not degrade signal characteristics by attenuation. Typical maximum suggested length for optimal performance is 2 m, although longer cables are possible if proper attenuation characteristics are specified. Two different sections make up the LEM. A high-frequency front-end generates the signals used for cylinder measurement, acquires the cylinder response and digitizes it. The digital backend applies algorithms to calculate position and velocity, and runs safety surveillance functions. Each single measurement from signal generation to processing takes approximately 300 µsec. This allows real-time position measurements in high-dynamics applications with very low latencies compared to most other established measuring devices. Each measuring cycle is repeated at different frequencies based on specific cylinder characteristics, thus providing redundant position information that can be used to compensate for instabilities and other effects. The LEM is considered a universal measuring device. Calibration parameters for different cylinder types are generated offline and downloaded during initial set-up. Cylinder length has no impact on system calibration; parameterization mainly depends on the ratio between piston and rod diameters.

Guard ring

LiView involves making real-time electrical measurements of a cylinder’s mechanical structure to determine piston position and velocity.

The LiView probes ensure capacitive coupling between electronics and piston rod. They are integrated in the high-pressure side of the hydraulic cylinder rod bearing, behind the primary seal. The probe’s contact element rides on a ﬂoating bearing. It ensures a stable electrical connection in a dynamic system, permits relative displacements along all three main axes and prevents wear to both the contact element and piston rod. The probes handle multiple functions. They permit a sealed highpressure cable feedthrough for routing a coaxial cable inside the cylinder structure. They couple the signal into the cylinder inner cavity. And they compensate for relative displacement between piston rod and rod bearing, thus ensuring optimal signal transmission during cylinder operation even in harsh environments. This is essential for heavy-duty applications, where strong lateral forces can continuously stress a cylinder. Real-world considerations

An important factor is sensitivity to oil instabilities. Measurement accuracy is influenced by the dielectric characteristics of the cylinder subsystem. Any change in oil permittivity (ε) due to temperature, pressure and aging effects on the oil or its constituents will affect dielectric characteristics. Pressure variations inside the cylinder will produce position-dependent changes within a few msec, while aging might impact measurements over weeks or months. That’s important because any parameter influencing the oil dielectric constant influences the propagation speed of electric signals inside the cylinder cavity. A change in signal speed generates a phase error of the measured signal, thus producing a systematic error on the calculated position. This error depends on the length of the travel path inside the dielectric. Techniques that counteract this behavior are essential for acceptable performance in real applications. Correction algorithms that run in real time during every measurement cycle compensate for temperature, pressure and aging effects of the hydraulic The system includes an electronics unit, two probes and a guard ring. Each measuring cycle, a signal generated at one port reflects off the piston and is intercepted at the second probe port. This analog signal is digitized in the electronics and processed to calculate position.

fluid. As a result, LiView has a total absolute accuracy specification of 0.6% FS (peak-to-peak) or ±0.3% FS, which represents the maximum expected absolute accuracy error. These values confirm the suitability of the stroke transducer for mobile machine applications. Repeatability of the measured position is another important performance parameter in real applications. Repeatability, often referred to as precision, is evaluated as the total deviation (minimum vs. maximum) recorded at each position during dynamic cylinder operation. For conventional stroke transducers the stated performance typically refers to ideal testing conditions in a laboratory. This is not possible with the LiView system, because measurements require the presence of the cylinder structure, which represents the major source of inaccuracies. These include both dielectric constant changes of the fluid and from displacements and deformations induced by forces and temperature gradients acting on the cylinder during operation. We performed field tests on various types of mobile machines in different environments, to evaluate overall system performance. We tracked the precision on a plunger cylinder of a mobile machine where working conditions included varying temperatures and loads. Data on dynamic cylinder performance were compared to a wire potentiometer (including its inaccuracy). Results confirm signal precision well below 2 mm peak-to-peak over the major part of the cylinder stroke. Functional Safety

LiView also meets demanding functional safety requirements. It has been developed to fulfill Performance Level d (DIN EN ISO 13849) and SIL 2 (DIN EN ISO 61508) requirements. The main difficulty with our approach relates to the intrinsic different nature of the LiView sensor concept compared to conventional transducers. The latter are based on a well-defined measuring path. (For example, in magnetostrictive transducers the measuring path is encapsulated within a predefined

The LiView system, shown here on an excavator arm cylinder, is available to both cylinder manufacturers and OEMs. It’s currently being tested in various applications, including shredders, agricultural equipment and material-handling machines. Series production of LiView-equipped crawler tractors and loaders is set to begin shortly.

LiView as a disruptive technology Liebherr engineers have noted the main error sources caused by changing oil dielectric properties and developed suitable compensation strategies. However, cavitation is also frequently encountered in real applications. In a bucket cylinder for instance, an abrupt variation of the mechanical load produces a fast piston-rod displacement that the hydraulic system cannot follow with sufficient oil flow. As a consequence, fluid pressure suddenly drops and bubbles or voids form in the fluid. LiView is able to detect this condition because it is extremely sensitive to changes in fluid electrical properties that affect measuring accuracy. The presence of air in fluid impacts the dielectric constant of oil and would result in an undetected position error. Surveillance algorithms identify this in real-time. The system notes a difference between measured and

metal bar that can be precisely manufactured and controlled by the sensor provider.) In contrast, LiView performs electric measurement of an external cylinder structure, not typically under control of Liebherr. While this set-up offers advantages in terms of robustness and serviceability in the field, compared to other options, it introduces additional complexity for safety. The main objective of the safety function is to ensure the measured position is correct. It is addressed by introducing surveillance functions operating at the component and system levels. At the component level, the LEM verifies signal characteristics that are produced and measured. That includes hardware and software monitoring functions. Hardware tasks range from tracking circuit-board temperature to monitoring all power supplies and core hardware elements through a complex surveillance circuit that includes a watchdog. Software monitors analyze both the generated and acquired signal characteristics. The firmware and all data-processing algorithms run on a lockstep processor with two independent computational cores that are continuously compared through the hardware surveillance function. This identifies and compensates for most possible errors, or notes that they require countermeasures. 118

predicted positions and generates a signal that correlates to the presence of air inside the cylinder chamber. The LEM generates a warning signal and provides important information to the machine controller, and thus supports more-stable hydraulics control. This capability can also be exploited to generate state information on the component and hydraulic system that includes the cylinder, which would not be possible using conventional technologies where the sensor is a well-conﬁned subsystem. In this context, LiView can be understood as a technology platform allowing real-time monitoring of the cylinder system state. The technology is based on complex measuring hardware, on which software functions can be added to implement new functions and provide further insight on the cylinder health.

System-level safety is implemented as a surveillance algorithm running in the LEM. It checks cylinder response to a known stimulus and compares the measured scattering parameters to the expected ones. Cylinder behavior can be predicted with a high degree of accuracy — on the order of 1%. Measurements at different frequencies produce intrinsic redundant information. The scattering parameter measuring technique continuously monitors the probe cables’ state and compensates for drifts due to mechanical, temperature and aging effects. This is performed every cycle. In case of anomalies, position information is flagged as potentially dangerous but is still broadcasted on the bus. Condition monitoring

Other important features of LiView include condition monitoring capabilities and reliable fault diagnosis. Thanks to its permanent selfmonitoring, LiView identifies any deviation between its current and optimum state. Thus, the system reliably detects faults such as undervoltage or defective probes. It also has an internal memory that saves previously diagnosed faults. The content of this memory is transmitted via the standardized diagnostic communication protocol UDS (Unified Diagnostic Services) as specified in automotive standard ISO 14229. The fault www.fluidpowerworld.com

memory is easily read out with a standard off-board diagnostic tool, or downloaded with software Liebherr can supply to OEMs. For users, LiView allows a detailed diagnosis of system faults — for the first time at the sensor level. Because LiView already detects the cause of the fault, the OEM does not have to conduct a complex and expensive fault analysis. This simplifies and accelerates appropriate repairs, avoids extended downtime and increases efficiency. Cylinder manufacturers also benefit. As soon as the intelligent position transducer is integrated into the cylinder, condition monitoring can check for proper functioning. The basic idea of using the cylinder as sensor is a promising approach for many heavy-duty applications, where both sensor performance and robustness are critical and for which conventional sensors are not a viable option. The limited envelope required for the integration of the probes in the piston rod bearing makes LiView suitable for smalldiameter cylinders. Moreover, this innovation opens a new approach to system-level state monitoring. by providing important cylinder state information to higher-level controls. FPW

Fred Babson, Business Development Manager, Delta Computer Systems Inc. Powder compacting presses are typically used to form complex shapes from

Compression cycle challenges

metallic, ceramic or other powdered materials that are hardened after compression via a high-temperature sintering process. In order to evenly distribute and compact the powder throughout a complex part die, multiple motion axes operating hydraulic rams, working together, may be required. This in turn requires coordinated multi-axis motion control. A case in point involves a new powder compacting press manufactured by Gasbarre Products Inc. of Dubois, Penn. Gasbarre makes presses in a variety of sizes, capable of exerting compaction forces from 1 to 750 tons. Most of the company’s customers are suppliers to the auto, lawn and garden, hand tool, and recreational vehicle industries.

During a compression cycle the axes (Figure 5) will typically switch between geared, synchronized and independent motion control at various times. This is done to smoothly and uniformly move the powder material into the die and then compact it, so that the density of each level of the molded part stays within design specifications. When decompressing the part, deflection compensation must be done on the various tool members because, depending upon the surface area of the punches, they will deflect differently.

Gasbarre’s new press (Figure 1) employs seven hydraulic cylinders operating concentric punches (Figure 2), and a linear servo actuator, to load a die with powdered material. The disk shown in Figure 3 is a simple example part produced by the press. Though it requires multi-axis compression to form, it is not as complex as parts which could be produced by the machine. 120

Without deflection compensation, as the tooling decompresses, the punches could spring back at varying rates, causing cracks in the part. The next challenge is to extract the part from the die. The machine must have enough flexibility in speed, position control and sequencing to eject the part from the die without creating any stress on the part which would result in cracks. Gasbarre engineers designed the hydraulic circuits to provide high flow to the cylinders for speed of operation, but they augmented the main proportional valves with smaller valves to be used for extremely accurate positioning. The main upper cylinder is able to achieve speeds of up to 14 in./sec during a rapid move and still position within 0.0002 in. Controlling the hydraulic circuits on this machine requires 15 separate tasks running simultaneously to smoothly handle the throttling of the various hydraulic valves.

When selecting a motion control solution to perform these functions, Gasbarre’s management wanted to use just one multi-axis controller. “Using a single motion controller makes system development and troubleshooting much easier,” said Larry Shindledecker, Gasbarre Electrical Design Engineer. In addition, Gasbarre needed a controller with high performance and high precision operation. “We are traveling at 10 in./sec and we need to establish our target position to ±0.0005 in.,” said Shindledecker. He selected the RMC200 electrohydraulic controller from Delta Computer Systems Inc. of Battle Ground, Washington (see Figure 6). “We started using Delta controllers ﬁfteen years ago with the RMC100 and then migrated to the RMC150,” said Shindledecker. “When we needed more axes than we could ﬁt into the eight-axis RMC150, we switched to the RMC200, which can handle up to 32 axes.” Good connections

A strength of the RMC200 is the ability to connect to a large number of input transducers. In the case of the new Gasbarre

press design, the motion controller connects directly to seven linear position transducers with SSI (synchronous serial interfaces) and 0.5 micron resolution. Figure 4 is an example of how one of the transducers mounts outside one of the lower cylinders. The motion controller also connects to 17 highprecision pressure transducers, one rotary SSI transducer and one load cell. Ten of the pressure transducers are paired, one on each end of five of the cylinders to measure the force that is being applied (the difference between the pressure readings corresponds to that cylinder’s applied force or load). “In addition to measuring force, we are monitoring pressures for diagnostics,” said Shindledecker. “The Delta controller makes a great tool for troubleshooting when transducer data can be recorded and graphed together.” “With the monitoring capability of the motion controller we will have more data available to assist in future upgrades and better utilization,” added Heath Jenkins, President of Press and Automation Business at Gasbarre. Besides the pressure transducers, the main upper cylinder is fitted with a load cell for the purpose of reading the compaction force that it delivers. Gasbarre’s experience is that the load cell provides more accurate force readings than using pressure transducers in cylinders, without needing to worry about external influences like seal friction. Programming the motion

The motion programming and tuning was done using Delta’s RMCTools software. The software uses drop-down menus and ﬁll-in boxes on screen to program the motion sequence for each axis. “Delta’s synchronization commands are straightforward and easy to work with,” said Shindledecker. “Most of the other motion controllers I have used are less intuitive.” For example, RMCTools developers can work directly with gear ratios, timing, and rates of acceleration and jerk (i.e, the rate of change in acceleration) without needing to do low-level machine programming.

“Initially, I had some concerns with utilizing the more complex features of the RMC like camming and advanced gearing,” said Shindledecker. “But I made a trip to the Delta factory and worked with a Delta engineer for a week on this project. This was very helpful.” The same RMCTools environment supports all of Delta’s current RMC motion controllers. “The software compatibility between the RMC150 and the RMC200 works out very well,” said Shindledecker. “It helped us reduce the programming time required for this product by letting us re-use motion steps in newer machines that we’ve used before.” RMCTools is also useful for troubleshooting, with a key component of the package being the Plot Manager. This is a tool that allows various motion parameters such as axis position, velocity, and hydraulic pressure to be plotted in real time and compared with target values produced by the control algorithm. The output is displayed on the screen of an attached PC or saved in a ﬁle for later review or archiving purposes. To aid in tuning the motion axes for optimal operation, Delta’s RMCTools software also contains a Tuning Wizard, which builds a mathematical model of the system being controlled and suggests what gains should be applied to the control loop parameters to minimize the error between actual and target motion. “I use the tuning wizard for RHAM-MKT QRAM PRINT Ad #1 2018-11-21 v1-0.pdf

the initial tuning on the different axes,” said Shindledecker. “After that I go in and modify them manually to optimize them for our process.” Besides actively controlling motion axes, Delta motion controllers can connect to additional transducers for the purpose of monitoring other status points on the machine. “The RMC200 has now given us what we have been asking for,” said Jenkins. “With up to 32 axes available we can now control all of our hydraulic axes plus gather diagnostic information.” “The functionality of this machine would be extremely difficult to accomplish without the use of the Delta RMC200,” concluded Shindledecker. And Jenkins added, “Now we offer a fully hydraulic technology, pressing with counterforce from below instead of hard stops (like most of our competitors). This means that everything is very precisely set based on a reference point that is easily controlled – unlike manual adjustments which other presses require.

Removing water from factory air and lowering the dew point protects automation equipment. Edited by Mary C. Gannon, Editor

One of the foremost causes of costly downtime and emergency maintenance in industrial automation systems is not oil or contaminants, which are easily removed with proper filtration, but water vapor and the resulting condensed water that is trapped in factory compressed air. Water in facility airlines can cause corrosion, rust and pipe scale which can break loose to block or adhere to air passageways that can lead to increased pressure drop and loss in machine performance. These machine components will suffer premature wear and parts deterioration from water: • • • •

pneumatic cylinders will have their pre-lubricants washed away, corrode and respond slower solenoid valves’ rubber seals will stiffen, become more susceptible to rupturing and leaking instrumentation can malfunction even with the presence of a small amount of moisture/water air powered tools will likely stick, jam and perform less efficiently

Recognize water entry points

All atmospheric air contains various contaminants and water vapor which is concentrated during the compression process. The heat generated during compression increases the capacity of the compressed air to hold moisture, thus avoiding condensation inside the compressor. Lubricants used to improve the efficiency and life of the compressor also become part of the contaminant load as do wear particles. A compressor with a 100-hp capacity, operating at 86° F ambient temperature, a relative humidity of 80%, compressing air to 100 psi, can produce approximately 30 gallons of condensate during an eight hour shift. Removing liquefied water from compressed air

Aftercoolers — The compressed air exiting the compressor can reach temperatures as high as 300° F, which is unusable for industrial applications. This hot, saturated air will release 70-80% of its excess water vapor if simply cooled to near room temperatures. To achieve this type of cooling and bulk moisture removal, air or water cooled aftercoolers are often employed. Condensed liquid is removed from the aftercooler via automatic condensate drains and disposed. The air exiting the aftercooler will still be saturated but at a much more manageable temperature. Because the air is at a dew 128

FLUID POWER WORLD

point of 100° F or more, it is still vulnerable to further condensation into liquid water should it be exposed to temperatures lower than this dew point. The piping in most industrial facilities would provide such temperatures and opportunities for condensation as the air moves throughout the plant. Drip legs — The next line of defense for removing the water vapor saturated compressed air is a drip leg. A drip leg is a vertical pipe plumbed at the air drop line (below the horizontal header pipe) to allow for water to be easily and efficiently drained away using the principle of rapid air expansion, or adiabatic expansion, to condensate water vapor into liquefied water. To broadly summarize adiabatic expansion, temperature is the average heat or kinetic energy of all the particles divided by a given volume of air; if the volume of air is increased through expansion, the heat is divided by a larger volume number, therefore decreasing the air temperature. If the drop in air temperature falls below its dew point, then a condensate will form. The condensate is then removed by a drain at the bottom of the drip leg which can be automatically or manually drained to avoid overflow of contaminants. Water separators — Water separators will use mechanical separation techniques to remove condensed water in bulk from factory air either by directing inlet air into a spiral and using centrifugal force to separate the water out from the compressed air or by passing the inlet air through a special resin filter element with large meshes to trap water particles that will drop down to a collection bowl, allowing the compressed air to pass through. SMC’s AMG series water separator is capable of removing water droplets up to a 99% water removal rate, using a special resin filter to trap water droplets. The AMG is easy to install and requires no electrical power and can be either a standalone unit or integrated in to a modular air prep system. However, the AMG water separator is not designed to remove water vapor or lower dew point which will require a refrigerated air dryer or desiccant dryer.

Heatless air dryers like SMC’s ID heatless air dryer can lower dewpoint to –30° C.

SMC’s AFF main line filter has a water droplet removal of 99% and particle filtration down to 1μm.

Lowering dew point

Failure to remove water vapor from factory air can quickly become a costly maintenance headache. Aftercoolers, drip legs and water separators are used to remove water condensate from factory compressed air. However, this air is still at 100% relative humidity and is still at risk of condensing into water should the surrounding temperatures drop to its dew point. In order to increase protection of expensive automation equipment, factory compressed air must remove as much water vapor as possible to avoid any condensation further downstream. This is done by lowering its dew point. Drying compressed air at the highest pressure consistent with the facility’s demands will result in the most economical dryer operation. For most industrial applications, the rule is to ﬁrst set the pressure dew point to meet general requirements, then adjust it 20° F lower than the facility’s lowest ambient temperature. Hence, factory air dryness or dew point is relative to the application’s speciﬁc requirements. Refrigerated dryers are the most common measure to lower dew point. A refrigerated dryer will further cool the compressed

The dryer will then reheat the dried compressed air back to ambient temperature by recycling the previously removed heat using a heat exchange process. This reheating of the compressed air to ambient temperature will eliminate “sweating” cold pipes when working in humid factory conditions. It is recommended that a coalescing filter be installed upstream from the refrigerated dryer to remove any compressor oil and other contaminants that may still be trapped in the compressed air to ensure the dryer’s proper functioning. Oil coating the cooling surfaces decreases efficiency while coalescing filters

saturated with liquid water will reduce its drying capacity. In circumstances where factory piping is exposed to ambient temperatures lower than the dew point achievable by refrigerated drying, alternate methods of drying must be considered. Membrane dryers use hollow fibers composed of a macro molecular membrane through which water vapor passes easily, but is difficult for air (oxygen and nitrogen) to pass through. When humid, compressed air is supplied to the inside of the hollow fibers, only the water vapor permeates the membrane and is drawn to the outside due to the pressure differential between the moisture inside and outside the hollow fibers. The compressed air becomes dry air and continues to flow unimpeded out of the membrane dryer.

A portion of the dry air from the outlet side is passed through a very small orifice to reduce the pressure and purge the outside of the hollow fibers. The moisture that permeated to the outside of the hollow fibers is discharged to atmosphere by the purge air which in turn creates a low partial pressure allowing the dehumidification process to continuously perform. By altering the air flow rate and membrane configurations, pressure dew points from 55° to –44° F can be achieved. Membrane air dryers are a cost effective solution for point-of-use applications for pharmaceutical manufacturing, packaging, laboratory environments and other applications. Desiccant dryers pass air through beds of desiccant, an absorbent material such as silica

gel or activated alumina, which adsorb water vapor to its surface to effectively lower dew points to temperatures well below that which a refrigerated dryer can achieve. Heatless regenerative models use a pair of desiccant beds which alternate in service while the off-line bed is regenerated via a pressure swing adsorption process. Pressure dew points from 16° to –40° F and beyond can be achieved with a desiccant dryer. Both membrane and desiccant dryers are adversely affected by the presence of oils or liquid water and must be protected with a quality coalescing filter. What is the appropriate dew point?

Over specifying an application’s or a facility’s dew point can be very costly due to exorbitant energy bills just as the maintenance costs for water vapor damage to product lines can be for an under specified dew point. Drying the entire factory compressed air supply to –10° F dew point is unnecessary and extremely wasteful. It is a sensible practice to dry the compressed air to a dew point 20° F lower than the factory’s lowest ambient temperature then subdivide each compressed air supply by application using zone or point-of-use membrane or desiccant dryers to provide the appropriate level of dryness. The costs of energy, downtime, replacing production components, end product defects or even loss of brand value are just a few factors to consider when determining an appropriate dew point. FPW

Hydraulic hose for drop-in replacement

QualiďŹ ed to one million impulse cycles, the MegaSys MXG 4K hydraulic hose is a lightweight, compact, highly ďŹ&#x201A;exible, drop-in replacement for conventional spiral hoses. Gates XtraTuďŹ&#x20AC; Plus cover, a standard upgrade on MXG 4K, oďŹ&#x20AC;ers improved abrasion and ozone resistance, providing improved durability when powering the most demanding ďŹ&#x201A;uid power applications. Tested under the same conditions as Gatesâ&#x20AC;&#x2122; EFG4K MegaSpiral hose, MXG 4K oďŹ&#x20AC;ers: â&#x20AC;˘

â&#x20AC;˘ â&#x20AC;˘ â&#x20AC;˘ â&#x20AC;˘ â&#x20AC;˘

Expanded I/O options for RMC200 The new U14 module combines several diďŹ&#x20AC;erent input and output types in a single module, increasing conďŹ guration ďŹ&#x201A;exibility and enabling RMC200 conďŹ gurations from 2-axis to 32-axis, in 2-axis increments. The U14 complements the family of other high-density RMC200 I/O modules with a smaller number of a wide variety of I/O types. With the U14, users can add up to two extra control axes, bring in a variety of diďŹ&#x20AC;erent reference input signals, or simply add additional analog and discrete I/O, all within a single module. The U14 analog I/O features four 18-bit resolution analog inputs and two analog drive outputs that are software selectable between Âą10 V, 4-20mA, or Âą20mA. Two high-speed channels are software selectable as Serial Synchronous Interface (SSI), Magnetostrictive Start/ Stop or Pulse-Width Modulated (PWM), or Quadrature Encoder inputs. Two high-speed discrete inputs provide homing or registration for the high-speed channels. Finally, there are four conďŹ gurable, individually isolated discrete 24 Vdc I/O points.

Ultimate ďŹ&#x201A;exibility: MXG 4K is 40% more ďŹ&#x201A;exible than conventional spiral hoses, reducing the amount of force needed to route, allowing for faster and more ergonomic installation. Unrivaled weight reduction: At 30% lighter weight, MXG 4K improves equipment performance, material handling, installation and ergonomics. Compact design: MXG 4K is, on average, 8% more compact, providing an easier ďŹ t that also enables upsizing hose selection for increased power. Leak-free: <0.05 sccm Excellent Linearity: <4% of full-scale Repeatability: <0.5% of full travel

Wire-actuated encoder for 12 m measuring The new SG121 wire-actuated encoder is suitable for measuring lengths up to 12 m and is both resilient and ďŹ&#x201A;exible. Long measuring lengths and a compact housing are requirements not only common in intralogistics and with manufacturers of mobile machines but in stationary machine construction as well. It is an important factor in the choice of sensors for new machine concepts. The new SG121 wireactuated encoder is unique on the market with its installation depth of just 70 x 85 x 105 mm. But the space-saving wire-actuated encoder makes no compromises when it comes to sturdiness. The robust aluminum housing, coupled with impact-resistant plastic, survives even the harshest of operating conditions. Temperatures between â&#x20AC;&#x201C;40 and 80Â°C, high shock and vibration loads, dirt, dust, and water make no impression on the wire-actuated encoder. For outdoor applications in low temperature ranges, a version with integrated water drain holes is also available. This prevents water that has penetrated the sensor from freezing at below-zero temperatures and thus increases the service life. 132

New liquid level transducer with temperature

Added strength for visual pop-up indicators Schroeder Industries has released a protective shroud for the D5 series visual pop-up indicators. This shroud protects D5 indicators against harsh environments and inadvertent impacts that cause indicator cracking/breakage. Visual pop-up indicators provide an economical way to know (at a glance) when a ďŹ lter element needs to be replaced. With the variance of operating conditions for hydraulic ďŹ ltration, the number of end-user-replaced indicators is at an all-time high. The D5S ďŹ ts onto the hex of the aluminum D5 Indicator body to provide additional strength in both the axial and lateral directions. Made with durable PA66 Nylon material, the D5S is lightweight (100 grams) and corrosion-resistant. In addition to the D5S package, the shroud will also be available separately to retroďŹ t any existing D5 indicators (SAP #7642053).

5 common failures of hydraulic cylinder seals

Piston Seal

It can happen at anytime, most often without notice — your

cylinder has failed. More often than not the failure can be attributed to a seal or seals used inside of the cylinder. Let’s take a look at the types of

Piston Seal

O-Ring

Wear ear Band

O-Ring

seals typically found inside a hydraulic cylinder.

• • • • •

Piston seals — Used to keep oil onto the work side of the piston. Rod seals — The most important seal type used to prevent leakage from inside the cylinder to the outside. Buﬀer seals — Absorb changes in pressure when working with high-load conditions. Typically placed in front of rod seal. Wiper seals — Prevent outside contaminants from entering the cylinder assembly/system. Wear bands — Guides the piston and rod of a hydraulic cylinder and absorbs transverse forces. Also, prevents metal on metal contact.

Wiper Seal Rod Seal O-Ring

The most common reasons for seal failure and some possible causes include the following: •

• •

Hardening — Too much heat being generated from a high-speed application or environmental conditions surrounding the cylinder. This can be avoided by using the proper materials for hightemperatures, or using shielding, insulation and cylinder cooling. Wear — Excessive wear due to not enough lubrication. Excessive lateral load results in worn bearing/wear ring. Scarring/Contamination — It can be easy for contaminates such as shop debris, wood splinters or improperly filtered oil to impact the cylinder operation. Once contaminates are inside the cylinder, it can lead to scars or imperfections on the rod or bore that will scar the seals. Fracture — Resulting from excessive back pressure, high pressure spikes/shocks and a loss of material/fluid over time. Improper Installation — Not using the proper tools to install seals can lead to damage and leaks. Most manufacturers offer installation tips, including surface specs and groove dimensions. In addition, inspecting tools for nicks or cuts can prevent seal damage. Finally, avoid twisting seals during installation.

Cartridge

Backup

on repeatability, whereas an engineer would requires the pertinent information disclosed to ensure the design is the best it can be. For instance, while there is an ideal working pressure, there can be spikes throughout the system that occur when a direction change happens. Additional or different seal designs can be implemented to control and handle the variations in pressure. This application data is critical when determining the seal types. Most manufacturers have this data readily available. An electronic application data sheet from Peninsular (peninsularcylinders.com/application-datasheet/) is used to determine a recommended cylinder design. The data sheet collects such information as working pressure, fluid pressure, temperature range, fluid type and more. General maintenance should also be conducted. For example, having a seal kit replacement on hand can extend the overall life of the cylinder. In some circumstances it may also make sense to have a backup or spare cylinder available to avoid costly downtime. Using the aforementioned application data and close relationships with design engineers can ensure the right cylinder and seal package for all demanding applications. FPW

The end user is most concerned with the cylinder being able to handle the required payload at a certain speed. They are also focused
