inspiring the Next Generation of Engineers

By Eric Alström, President, Danfoss Power Solutions

»AS UNIVERSITY STUDENTS

near graduation, their thoughts turn from coursework to career. With various occupations and industries to consider, engineering graduates are often excited about solving complex electrical or mechanical challenges and having a positive impact on the planet. Many look to the automotive, aerospace, and other industries that have a technology-forward image and align with their ambitions to contribute to a better world. Often, the company names are well-known consumer product manufacturers.

Rarely, however, do graduates discover the hydraulics industry and the many opportunities it offers. Fluid power companies need to work hard to attract engineers, usually because of the old-fashioned image that oil hydraulic products represent. However, that image couldn’t be further from reality. We need to both familiarize and excite aspiring engineers with the cool things that characterize our products today.

We also need to raise awareness of the substantial technical developments required to serve the next generation of sustainable development in our industry. As president of one of the world’s leading hydraulics suppliers, I call this “opening the Danfoss box.” Virtually no hydraulic applications can run today without software, microcontrollers, sensors, and electrically actuated hydraulic pumps, motors, and valves. This presents a fascinating multidisciplinary mechatronics problem that should excite the most technically interested engineers. In fact, electronics and software are so important that about half of our 1,800 engineers are developing software and connected products.

The potential to lower emissions and improve productivity through better technology is significant. Hydraulic systems generate many of the energy losses that occur in a diesel-powered machine. The more efficient we make the hydraulic system, the greater the overall machine efficiency. But for many customers, that isn’t enough. Productivity is

just as or perhaps more important than efficiency. This is where control systems, software, and intelligent products come into play. They are tools to solve the challenging design problems of machines. Once engineers understand the contribution of these technologies to optimizing fuel efficiency, productivity, and even the circularity of products – particularly as the ESG (environmental, social, and governance) movement rapidly grows in importance – they tend to raise hydraulics on their list of potential industries in which to work.

When engineers learn they can develop green solutions that enable us to produce more with less, they quickly become interested in working for us.

Electrification also increases the attractiveness of our industry to young engineers. Many of our solutions today are electrohydraulic, meaning electronic controls and/or electric motive power driving hydraulic systems. Their positive impact on productivity and efficiency is significant. Some cases have shown over 30% improvement in productivity while operating emission free and using less energy. The benefit to society is tangible and exciting. When engineers learn they can develop green solutions that enable us to produce more with less, they quickly become interested in working for us.

Solutions is another keyword that attracts engineers to our business. Many OEMs are outsourcing hydraulic and system design to suppliers like Danfoss. Our impact on overall machine performance grows as we are given more of the system to control. In fact, from a hydraulics standpoint, we sometimes understand the applications better than our customers, as we interact directly with end users to better understand their needs. Gaining this in-depth application know-how and experience in systems engineering appeals to young engineers. For many people in the field, engineering an entire system is a dream; in hydraulics, it is often reality. However, all of these fascinating facets of hydraulics only become interesting to a young engineer when we “open the box.” It is no small challenge, and we need to be close to the emerging technical talent at universities to make it happen. As an industry, we need to commit to supporting education by investing time and money. We can offer internships and provide equipment for labs and classrooms. Equally important, we can be present in classrooms and cocurricular activities, serving as role models for tomorrow’s engineers. After all, collaboration moves us all forward together.

How Fast Can a pig Travel?

By Ernie Parker, CFPAI, CFPSD, CFPS, CFPMM, CFPMT, CFPMIP, CFPMMH, CFPMIH, CFPE

»A GAS PIPELINE was updated in my home area. The work included installing a line under the Minnesota River that runs to the residental area. In the final stages of the work, after checking for leaks or other problems, they ran a “pig” through the entire line to clean it before running natural gas through it. A pig is a plug that rubs the edges for cleaning. Normally a pig goes through at 0.2 MPa (30 psi) but may take as high as 0.55 MPa (80 psi). The pressure in the pipeline will be 1.724 MPa (250 psi) but proof tested to 2.75 MPa (400 psi). Using the followings specifications, how long would it take for the pig to travel the total distance at 0.2 MPa (30 psi ) and at 0.55 MPa (80 psi)?

CHOOSING THE RIGHT PNEUMATICCYLINDER PNEUMATIC PNEUMATICCYLINDER CYLINDER

Todaythere are more sizes, styles, and shapes of pneumatic cylinders than ever, which complicates the task of choosing the right one for your application. Of the various decisions to make, specifying the right size cylinder is especially critical. An undersized cylinder could mean you won’t be able to perform the required task, while oversizing a cylinder wastes resources by using more air than is necessary and costs more for additional capacity that is not required.

Other considerations affecting size and model selected

Beyond calculating how much force you’ll need for your operation, other considerations when sizing a pneumatic cylinder include:

Stroke length. The length of your stroke could be as short as 1/16 of an inch to 100 or more inches. Many cylinders can be ordered in exactly the stroke needed for a particular application. Some cylinder offerings are produced in finite stroke lengths that are sometimes stocked by the manufacturer for immediate delivery.

Space limitations. The physical space available for the cylinder in the application is an important consideration. Cylinders are offered in various industry standard envelope sizes defining the physical size and shape of the cylinder. ISO and NFPA publish standards that manufacturers follow. Some cylinder lines are unique to a manufacturer and not defined by a standards organization.

There are multiple considerations when determining the best cylinder size. The most critical is the force required to perform the task. The cylinder extension force can be calculated by multiplying the effective surface area of the cylinder’s piston by the air pressure supplied to the cylinder. When retracting a double-acting cylinder, the piston rod takes a portion of the effective surface area, and you need to subtract the area of the piston rod from the area of the piston. After determining the amount of force needed, it’s important to add in a safety factor. With a plant full of machines running at the same time, total air pressure demands in the plant may exceed availability, creating an occasional drop in air pressure. That’s one of the reasons why a safety factor is suggested, typically about 25% above the amount of force you anticipate needing. This ensures you have the force you need even if air pressure fluctuates within the plant. The additional capacity also allows for changes in the application.

Speed. How fast does your cylinder need to extend or retract? At high speeds, choosing a cylinder with adjustable end-of-stroke cushioning allows for higher speeds than without cushioning. Cylinders are limited in their kinetic energy absorption ability. A cylinder used beyond those sustainable limits will likely lead to premature failure of the cylinder. That’s why many cylinder manufacturers, like Parker, publish kinetic energy rating charts to allow machine designers to confirm this important aspect of cylinder selection. The greater the moving mass and speed, the more energy absorption capability that is necessary. The mass includes not only the piston rod assembly but anything attached to the end of the piston rod.

Noise. Cylinders with end-of-stroke bumpers are quieter. Many cylinder manufacturers offer bumpers for the extend and retract strokes. Bumpers are generally in the form of a rubber stop. Principally they reduce noise and offer end-of-stroke cushioning. Government agencies and other groups routinely express concerns over hearing loss in plant operators from exposure to industrial noise. Bumpers may help reduce noise levels in the plant in compliance with local regulations.

Available air pressure. Most plants typically have between 80 and 120 psi (5 and 8 bar) air pressure available. It’s important to match the rating of the

cylinder with the amount of air pressure available. Typically, cylinders are rated for use up to 150 psi (10 bar), although some standard cylinders are rated to 250 psi (17 bar).

Considerations beyond size

Once you’ve chosen the right cylinder size, you can turn your attention to the myriad options available today. Most cylinders on the market today are aluminum with chromeplated steel piston rods that resist corrosion. There are also heavy-duty steel cylinders appropriate for applications that may require additional durability, like for use in steel manufacturing and other harsh environments. Here are a few other choices:

Compact cylinders. These are ideal for applications that require less force and have limited space available. Parker recently introduced its P1P Series, a complete range of compact cylinders for these types of applications.

Single-acting cylinders. Although most cylinders are double-acting, meaning the power stroke is in both directions, single-acting cylinders are ideal when thrust is needed in only one direction. The inactive end is vented to the atmosphere through a breather or filter. Spring force or gravity returns the cylinder. This can simplify and lower the cost and complexity of control valves and logic. Cylinders can be ordered with spring extend or spring retract depending on the application requirement. The spring is internal to the cylinder and will require additional cylinder body length to accommodate the spring components. The spring component design and configuration generally limits stroke length to about 6 inches.

Double-rod cylinders. Double-rod cylinders are used when equal displacement is needed on both sides of the piston or when it is mechanically beneficial to couple a load to each end. The extra end can be used to mount cams for operating limit switches, and so forth.

Guided cylinders. Tools that need a specific orientation require a cylinder that prevents rotation. Guided cylinders are mounted in a housing that has guide rods and a tool plate. They are in widespread use in applications involving lifting, pressing, pulling, separating, controlling product flow, and many other applications. Guided cylinders can tolerate the catalog-defined side load rating, whereas a standard cylinder, not mounted in a guide unit, can withstand little to no side load.

Rod locking cylinders. Safety is always a priority. Rod locking cylinders can be used to increase safety in the case of compressed air supply failure. For static applications, they can activate to provide emergency holding strength during a power outage or accidental disconnection of the air supply. These cylinders lock in place when air pressure drops, minimizing potential injury to operators and possible harm

to equipment. Some manufacturers also offer dynamic rod locks that slow and stop the piston rod when a safety interlock is triggered. Due to their unique design, these types of cylinders require additional pneumatic controls, and more space and length.

Rodless cylinders. Designed to maximize stroke length in relation to overall cylinder length, rodless cylinders are compact to effectively save space. Instead of using

an extending piston rod to move loads, they have a carriage directly coupled to the piston. The carriage moves in parallel with the piston and the same force is generated in both directions. Without a piston rod there is no subtraction of the piston area due to the piston rod diameter. It has the same effective piston working area in both directions. Benefits of rodless cylinders include:

• High load and moment capability.

• Load and moment capability that can be easily increased with guides on the cylinder.

• Various integrated brake options.

• Ability to be used for multi-axis pick and place.

• Smooth operation with low noise levels.

Sizing other components

Size matters when optimizing the performance of a pneumatic system. Valve sizing, for example, is greatly influenced by the flow requirement. How quickly the cylinder extends and retracts greatly influences the flow requirement. A larger cylinder with a longer stroke requires more air flow, which means a larger valve with a greater flow rating will be necessary. The number of cycles per minute (determined by output rate) also affects air flow which, in turn, affects hose and valve selection, and air preparation requirements for filters and point-of-use regulators. Proper air filtration will ensure a longer, more efficient life of the pneumatic cylinders.

Since the sizing of multiple components within a standard pneumatic system is so critical and complex, Parker created its Virtual Engineer online tool, which aids in the selection of the right products. As previously mentioned, the correct component size impacts the overall performance

and cost of a pneumatic system. While sizing is often a consideration when building a new line, many plants could benefit from an audit that could determine, among other things, if downsizing is an option when components need to be replaced. Don’t simply assume you need the same size cylinder, valve, or filter, especially after changes in the line. •

Cool Applications Need

Lubricating oil must deliver effective wear protection for compressors in food and beverage plants, cold storage facilities, chemical mills, and ice arenas.

By Eric M. Rud, Global Product Manager, Filtration Division, Eaton

Properlubrication of refrigeration compressors is critical, making effective filtration vital to smooth-running systems. The lubricating oil must deliver effective wear protection for reciprocating, vane, and screw compressors in industrial refrigeration systems. These systems are commonly found in food and beverage plants, cold storage facilities, chemical mills, and ice arenas.

Particles in the lubricant increase compressor wear and reduce the life of mechanical components. Excellent filtration systems are therefore necessary to maximize compressor life and prevent costly downtime. Oil degeneration or aging causes the buildup of damaging compounds leading to premature wear of moving parts. This reduces compressor efficiency and reliability, resulting in higher energy and maintenance costs.

The life of a lubricant is not easy

Many circulating oils developed for industrial refrigeration compressors are designed to operate in ammonia refrigeration systems. Ammonia refrigeration compressors tend to be highly efficient and reliable with proper care. The oil must be able to lubricate surfaces under demanding conditions without carrying the ammonia with it or permitting wear.

There are two main types of filters in refrigeration compressor lube systems. The first provides particulate screening in the oil; the second separates ammonia from the oil. To ensure maximum efficiency, the amount of ammonia that dissolves in the oil must be minimized.

It is imperative to consider the quality of the filtration solution as commercial refrigeration applications face different challenges compared to standard industrial filtration needs. The element must filter oil slightly contaminated with refrigerant. The filter housing meanwhile must be durable for the often-demanding conditions of the environment in which it is installed.

Filter efficiency is expressed as a beta ratio (ẞ) produced by the multipass filter performance test (ISO 16889). Results are reported as a ratio comparing the number of particles greater than a designated size (ẞx) upstream versus downstream of the filter during testing.

When selecting a filter for use in a refrigeration compressor lubrication system, a minimum beta ratio of ẞx>= 200 (99.5% of contaminant particles size “x” or larger are filtered) should be selected. Filter fineness recommendations vary by compressor manufacturer but generally fall within the 3µm to 10µm range.

Also critical is the dirt-holding capacity, pressure drop characteristics (delta p) and beta stability of the filter. Beta stability is the ability of a filter element to perform well in a dynamic refrigeration compressor system and not simply in a laboratory.

Today’s most innovative filter elements use multiple layers of synthetic media to maximize performance in all areas. Each filter layer provides a certain function that supports filtration performance, dirt-holding capacity, or beta stability.

Filters for cooling applications

Eaton has developed a standard approach to industrial compressor filtration using special NH3-resistant filter elements protected by carbon steel or stainless steel housings. These filter elements are specifically designed for compressors working with oil and ammonia mixtures (the most used refrigerant) or with other common refrigerants (typically CO2, N2 or halogenated hydrocarbons).

The combination of high-integrity pressure containment vessels and NH3-resistant filter elements effectively cleans lubricating oils and guards against the ingress of environmental contaminants. These filter elements are specifically suitable because they are resistant to ammonia that is often contained in compressor lubricating oils (NH3 up to 10% gases). These filters are equipped with ammonia-resistant support fleece and adhesives that withstand a maximum temperature of 194°F (90°C) to help ensure refrigerant compressors can continue to operate reliably.

The combination of industrial pressure filters and special NH3-resistant filter elements helps to ensure oil integrity and protects downstream components from contamination levels per the recommended cleanliness target. Most low-pressure filter arrangements (simplex or duplex) are suitable for working pressures up to 913 psi (63 bar). Associated filter elements having

A NEW GENERATION OF DOUBLE PUMPS DOUBLE PUMPS

By Catherine Zhuang, Product Manager, Hengli America

Hengli’s HP21VG series of axial piston variable double pumps boast high performance, compact design, and high power density that can meet a customer’s application requirements of high pressure, high speed, frequent shock, and other harsh working conditions.

Overall, these pumps feature a concise, high-performance design that uses fewer parts than previous hydrostatic products. The more compact design gives design engineers more freedom and flexibility in system design.

The HP21VG’s variable pump working circuit is closed circuit with pressure of 42-45 MPa (6,091-6,526 psi). Hydraulic, electric, and mechanical servo controls can be developed according to customers’ needs, and DA or emergency brake valves can be integrated as well. The pump is spline shaft driven, with working oil port A/B on the same side of the casing, with direct acting high pressure relief valve, without bypass and charge pump.

Features and advantages

High efficiency. Control of hydraulic flow rate and direction by an electrohydraulic integrated servo system ensures extremely low servo pressure and superior high power density. The extremely high operating efficiency allows the HP21VG series pumps to reduce the total cost of ownership.

Compactness. The low number of total components and the compact arrangement of the oil ports and control valves substantially shorten the overall pump length and facilitate installation in tight spaces. The compact design coupled with the high-pressure and speed ratings gives it a higher power density ratio.

Better design. Using a low-noise casing while optimizing the structure of the flow distribution plate helps meet the low noise requirements of the whole machine for hydraulic components. Strengthened shaft and bearing parts ensure the rotary accuracy of the pump and make it operate reliably ultrahigh pressure.

Control options

Hydraulic control, electric proportional control (voltage 12V DC and 24V DC), mechanical servo control, and other control options are available to meet the needs of multi-industry applications.

Multifunctional combination. The pump can be integrated with DA or emergency brake valve to obtain newer and better functions. For example, when the DA valve is integrated, the HP21VG closed double pump can be given a special control method to achieve stepless adjustment of hydraulic pump displacement.

In practical applications, the HP21VG series closed double pump can be used with any existing Hengli motor to form a hydraulic drive system to realize fluid transmission and control. As described above, it can also be used with DA valve to realize functions such as automatic driving and hydraulic DA of the vehicle, which is a good helper for hydrostatic travel system.

For example, in the actual application of skid steer loader, the main pump uses the HP21VG45 axial piston variable closed double pump, and HRP series radial piston motor to form a strong, efficient, automated, low fuel-consumption hydrostatic closed travel system that can meet the traveling condition under full load and the traction condition when shoveling. Moreover, smooth transitions while starting, stopping, or turning results in a more comfortable driving experience.

Based on the development of electrification, the HP21VG closed double pump is easily compatible with Hengli’s HLEC6448A series or HL-C series controller to enhance the functional adaptability of the whole machine. •

PUSHING HYDRAULIC FLUIDS FORWARD

By Blayne McKenzie, Technology Manager, Industrial Oils, The Lubrizol Corporation

Today’s hydraulic machines have undergone significant design modifications in recent years, but their importance in modern industry is unchanged. The overall growth of the global hydraulic equipment market, including in Asia Pacific, Europe, and the Americas, shows no signs of slowing. It is expected to continue expanding at a compound annual growth rate of 4.13% through 2024.

Indeed, hydraulic systems are responsible for reliable operation in countless critical applications, and it’s important that they perform to the best of their abilities throughout their lifetimes. And as hydraulic systems themselves continue to evolve, so too must one of their most essential components for optimal operation: hydraulic fluids. This article walks through the necessary performance characteristics required in modern hydraulic fluids, and it explores the greater potential for new improvements that can be made with advanced performance polymer technology.

Operational conditions

Today’s hydraulic fluids must contend with increasingly harsh operating conditions, as OEMs continue to iterate system designs to maximize machine efficiency while controlling costs. Achieving both goals simultaneously can create new challenges for fluids to contend with. For example, hydraulic fluid sumps have been a primary target of downsizing, which has been an effective weight-and-materials reduction strategy for OEMs. But it necessitates that smaller volumes of hydraulic fluids perform the same amount of work throughout the hydraulic system. As a result, the fluid necessarily operates at higher temperatures and, because there is less time for fluid to cool within the sump between work cycles, it remains at elevated temperatures for extended periods of time. These conditions have detrimental results on a hydraulic fluid’s ability to provide its essential functionality. Consider that one of the most important characteristics of a high-performing fluid is its ability to retain its designed viscosity throughout use. Sustained higher temperatures elevate a fluid’s potential to lose viscosity and become thinner and thinner. As the fluid loses viscosity, its protective film layers are compromised.

Those layers are critical, particularly in strenuous high-speed applications in which maintaining film thickness is critical. If a fluid loses its film thickness at such speeds, the fluid will not be able to deliver the expected protection, and parts can become worn prematurely throughout operation. For end-user operators, worn parts can lead to compromised machine performance and even machine failure. Either situation can become detrimental to an organization’s bottom line, as the resulting repair costs and production losses due to downtime add up.

This all makes viscosity retention a critical performance characteristic in modern hydraulic fluid formulations. The deployment of high-performance additives and performance polymers in the contemporary formulations can help significantly. To demonstrate these capabilities, Lubrizol’s testing team recently compared several experimental ISO 46 hydraulic fluid formulations to validate the potential of a new ethylene-propylene copolymer (OCP) that can enhance viscosity retention. The testing compared a multigrade fluid formulated with OCP (PP1) and versions of a multigrade fluid with a more conventional polymer, poly alkyl methacrylate (PP2).

First, both formulations were subjected to OEM pump testing. The data was clear: PP1, containing the new technology, exhibited low viscosity loss and retained viscosity well across many hours of service. This leads, of course, to greater retention of protective film thickness.

Second, in order to demonstrate the polymer’s applicability to realworld environments, we subjected each formulation to many hours of testing in tough field environments. The application was a hydraulic telehandler. Depending on the attachment mounted to the end of its boom, a telehandler can be used as an all-terrain forklift, crane, aerial work platform, or even an excavator – each of which represents a challenging duty cycle with high shear potential for an applicable hydraulic fluid.

In our testing, we found that PP1 once again delivered exceptional viscosity retention across thousands of hours of work. While PP2 also demonstrated strong shear stability, the elevated performance of PP1 can make a significant difference for end users over time. A fluid’s ability

to maintain its viscosity over extended periods of time can allow end users to extend a hydraulic drain interval, lessening maintenance burdens and allowing operations to continue uninterrupted.

Advancements in efficiency

Viscosity retention was not the only performance characteristic Lubrizol’s testing team sought to validate in evaluating OCP’s potential impact on modern hydraulic fluid formulations. Because the need for greater energy efficiency has been the primary driver of design changes we have seen in hydraulic systems, we sought to demonstrate a performance polymer’s ability to contribute directly to new efficiency gains that can improve an end user’s bottom line.

To evaluate potential efficiency gains, we introduced a conventional monograde fluid with no performance polymer as a baseline to our testing. The three experimental formulations were tested via controlled experiments within Lubrizol facilities and in off-site, climate-controlled laboratory settings, across a range of common hydraulic work cycles.

In each, PP1 demonstrated clear efficiency gains versus PP2 and the conventional monograde fluid. Testing was performed at consistent flows and pressures, and across numerous different pressure and flow combinations, in order to validate efficiency gains in a range of applications.

The OCP technology used in our PP1 fluid improves the fluid’s secondary flow properties, which helps create efficiency gains that are realized throughout the hydraulic system, outside of the pump. Secondary flow is where the hydraulic fluid is moving in a different direction to primary flow within an application. Secondary flow typically occurs when flow is constricted or changes direction within the hydraulic system. Secondary flow can thereby prevent the fluid from moving as effectively and efficiently as possible— OCP helps to mitigate this issue, thus directly contributing to improved efficiency. The efficiency benefits of the OCP polymer only grow in more complex systems, where more secondary flow events are likely to occur.

High-performance fluids matter

Modern hydraulic equipment has created new demands of hydraulic fluids, and it’s critical that such fluids remain up to the task. As demonstrated by Lubrizol’s testing, new additive and polymer chemistry has the potential to improve the essential protective characteristics of today’s fluids while providing new efficiency benefits.

For fluid formulators, it is worth exploring ways these technologies can improve formulations to best protect hydraulic equipment. For end users, selecting high-performance hydraulic fluids can deliver real-world benefits, helping to maximize the useful life of hydraulic equipment while minimizing maintenance requirements when such equipment is in service. Hydraulic equipment continues to play a critical role in the modern world, and maximizing its potential with the right fluids stands to benefit everyone. •

Hydraulic Components in Circuits Mobile Valves

Load-sensing

valves are designed to be used with a load-sensing pump.

The valves typically have spools with metering notches allowing proportional control of the affective orifice caused by the spool movement, both to the A and B ports. A shuttle valve usually allows the signal from the port with the higher pressure to be sensed by the pump control. Bernoulli taught us that there would be a discrete flow rate for a given pressure drop across an orifice. If the load-sensing compensator at the pump is set for a 17 bar (246 psi) differential, then any spool position will have a constant flow rate, regardless of variations in load pressure. This is particularly useful in mobile equipment when the valve is manually operated, and the only feedback is from the operator. However, if more than one function is being operated, the function with the greatest pressure-demand will be load-sensing. Other functions will no longer have a steady flow for a given spool position.

can be added to the circuit, usually within the main valve body of each valve section. There are two types of these compensator arrangements: precompensation, in which the additional valve element is placed in the fluid stream before it has passed by the control orifice (usually the main valve spool); and postcompensation, in which the additional valve element is placed in the fluid stream after it has passed by the control orifice. Both types of compensators sense core pressure and when required add restrictions to ensure a constant pressure drop across each control orifice regardless of load pressure differences.

In the first arrangement, the normally open precompensator valve element senses the load pressure, and if the pressure from the pump is higher than the compensator spring setting, nominally 17 bar (246 psi) above the load pressure, the compensator valve element restricts the flow and reduces the pressure across the control orifice to 17 bar (246 psi) above load pressure. The compensator is similar to a pressure reducing valve set at 17 bar (246 psi) with its spring chamber vented to the working port. The working port pressure is added to the spring setting of the valve. The result is a relatively consistent pressure drop related to the spring force and consequent flow rate for a given spool position, regardless of pump pressure or working port load pressure changes. This mitigates against the interaction of functions as long as there is enough pump flow to satisfy all activated work functions. The precompensator arrangement is best suited for accurate flow regulation circuits.

For example, in the precompensation circuit shown in figure 2a, pump flow maximum is 45 lpm (11.9 gpm). Note: The load-sense differential setting of the pump is 20 bar (290 psi). Function 1 maximum is 30 lpm (7.9 gpm), 100 bar (1,450 psi). Function 2 maximum is 25 lpm (6.6 gpm), 210 bar (3,045 psi).

Load-sensing valves with compensation. A load-sensing system that operates only one actuator at a time will supply the proper flow and pressure to that function because there is a consistent pressure drop across the control orifice. However, when there are multiple functions that need to be controlled at the same time, the function with the highest pressure requirement determines the core system pressure. Circuit sections that need lower pressure will receive an increase in flow due to this increase in core pressure. To overcome this problem, flow control compensators

Figure 1: Load sense schematic.

Figure 2a: Precompensation, one valve actuated.

Figure 2a shows the operation of one function. If function 1 is operating at 1/2 flow, 15 lpm (4 gpm), and maximum pressure, the load-sense pressure signal to the pump will be the load pressure. The pump outlet pressure will be the differential setting plus the load pressure: 100 + 20 = 120 bar (1,450 + 290 = 1,740 psi). The valve compensator will maintain a 17 bar (246 psi) pressure drop across the spool valve, and the remaining 3 bar (44 psi) pressure drop will be across the compensator.

As shown in figure 2b, if function 2 is actuated and operates at full load pressure while function 1 is still at 50%, the load-sense pressure signal to the pump will now be 210 bar (3,045 psi). The pressure at the inlet of the function 1 compensator will increase by 110 bar (1,595 psi); 230-120 bar (3,335-1,740 psi). The higher pressure will result in an increased pressure drop across the function 1 compensator, but the flow will remain essentially the same. The pressure drop across the valve 2 compensator will be 3 bar (44 psi), and the pressure drop across the valve 2 spool will be 17 bar (246 psi).

As long as demand does not exceed the pump supply, both functions operate at their desired speeds, and the load-sense signal will be the highest load pressure value. Each valve section compensator will continually adjust to maintain a constant pressure drop across the spool it is sensing.

Figure 2c shows excessive flow demand. Hypothetically, if both functions are commanded to 100% simultaneously, both functions 1 and 2 require more flow than the pump can supply. As long as it has a lower load pressure, function 1 will get the full required 30 lpm (7.9 gpm), and function 2 will get the remaining 15 lpm (4 gpm). If function 1 flow command is reduced, function 2 will increase in speed. If function 1 is commanded to less than 20 lpm (5.3 gpm), function 2 will operate at full speed. In practice, since the function pressure may change based on the supplied flow, the function speeds may not be consistent at full command.

Continued on page 18

Figure 2b: Precompensation, both valves actuated.

Figure 2c: Precompensation, both valves actuated, but inadequate flow.

In postcompensation, the compensator is a normally closed valve that opens when the pressurized fluid coming from the main spool pilots it open against a spring. The spring chamber is vented to the load-sensing line, which sees the highest load pressure. The pressure to open the compensator equals the spring pressure plus the highest load pressure. The net result is a consistent pressure drop across the main spool. Because the valve spool pressure drops are all the same, this arrangement has the advantage of restricting the flow to all work ports if the flow demand exceeds the capacity of the pump. All functions will slow down proportionally. The postcompensator arrangement is best suited for multiple working function applications requiring limited pump flow. It is not capable of accurate flow regulation due to the dependency on the pump's load-sense differential pressure setting, also commonly referred to as margin pressure.

In the postcompensation circuit shown in figure 2d, using the same values as the precompensator examples: pump flow maximum is 45 lpm (11.9 gpm). Note: The load-sense differential setting of the pump is 20 bar (290 psi). Function 1 maximum is 30 lpm (7.9 gpm), 100 bar (1,450 psi). Function 2 maximum is 25 lpm (6.6 gpm), 210 bar (3,045 psi). Function 1 is commanded to 50% flow, which is 15 lpm (4.0 gpm). Since the pump can provide more flow than needed, both valve sections will receive the correct flow. The compensator sections are sensing pressure upstream

and downstream of the spool valve. The pressure drop across each valve spool is the same. The load pressure does not affect the compensator modulation. The highest load pressure is being sensed at the pump. As long as the valves do not require more flow than the pump can provide, the performance will be the same as the pre-compensated valve.

Figure 2d: Postcompensation, example 1.

In the postcompensation circuit shown in figure 2e, if both valves are commanded to 100%, the flow demand exceeds the pump output. Because the individual compensator sections maintain the same pressure drop across the valve spools, the flow will be proportionally reduced, so the functions of both sections will have reduced speed. When using

compensated valves with load-sense pumps, it is recommended to set the pump load-sense differential pressure setting higher than the valve compensator setting. In the examples shown, load-sense differential pressure setting was 20 bar (290 psi), and the valve compensator was 17 bar (246 psi). •

Membership vs. Certification FAQs

»MANY PEOPLE ASK about the difference between certification and IFPS membership. Here are answers to that question and others we are frequently asked.

Q: What is the difference between renewing my membership and my certification?

A: Membership and certification are two different entities. When you renew your membership, you are not renewing your certification. Recertification requires an online application. IFPS membership is not mandatory, but it is highly encouraged.

Q: I took my certification test. Why do I need to recertify?

A: Because technology changes all the time and IFPS wants to make sure you are up to date with industry information. You wouldn’t want your doctor operating or making a diagnosis if they didn’t continue to stay current in their fields, would you? Therefore, the Fluid Power Certification Board requires ongoing experience, education, and training in the fluid power industry. The recertification process works on a system of professional development points, which can be earned in a number of ways:

• Work in fluid power field a minimum of three years.

• IFPS membership.

• Participate in fluid power committees/subcommittees.

• Participate in other fluid power organizations, such as FPDA, NFPA, NAHAD, SAE, and NAFA.

• Hold volunteer positions in fluid power organizations.

• Attend industry-related meetings.

• Attend vendor workshops, seminars, webinars, and in-house training.

• Present at a vendor workshop, seminar, webinar, or in-house training.

• Earn or teach industry-related college credits.

• Submit articles or technical papers to Fluid Power Journal.

• Submit a sample test question with required references and appropriate graphics and/or schematics to IFPS headquarters.

Q: How do I recertify?

A: Log in to your IFPS account, visit https://www.ifps.org/certifications and follow the instructions.

Q: What if I forget to recertify?

A: An IFPS certification is valid for five years, then it must be renewed. IFPS sends recertification reminders in emails, letters, and postcards; however, it is your responsibility to submit the required paperwork by the deadline. Please be sure to update your contact information by updating your account on our website. If you do not submit the paperwork by the expiration date, you may be required to retake the test, and you may no longer use the certification designation after your name. If you’re not sure if your certification has expired, check your profile on the IFPS website or email info@ifps.org.

The Certification Committee chair is James O'Halek, CFPAI/ AJPP, CFPMM, CFPMIP, CFPCC, of The Boeing Company. Vice chair is Steve Bogush, CFPAI/AJPP, CFPHS, CFPIHM, of Poclain Hydraulics. For more information, visit www.ifps.org.

Here is the solution to Air Teaser on page 5.

»

METRIC

1. Find area of pipe: 609.6²x 0.7854 = 291,864.19 mm² = 0.29 m²

2. Find volume of pipe: 0.29 m² x 2,134 m = 618.86 m3 x 1,000 = 622,840 liters

3. Calculate lpm: Find compression ratio: (0.2 MPa + 0.101) / 0.1 = 3:1 C.R. 45,312 Nlpm / 3 C.R. = 15,104 lpm

4. Volume of pipe/lpm = 622,840/15,104 = 41.24 minutes

5. Calculate for 0.55 MPa:

C.R. = (0.55 + 0.101) /0 .1 = 6.51:1 C.R.

45,312 Nlpm / 6.51 = 6,960.37 lpm.

622,840 / 6,960.37 minutes = 89.5 minutes

» IMPERIAL

1. Find area of pipe: 24² x .7854 = 452 square inches. Divide by 144 = 3.14 square feet.

2. Find the volume of air required to move the pig 7,000 feet: 3.14 x 7,000 = 21,991.2 cubic feet.

3. Calculate cfm: Find compression ratio (C.R.): (30 psi + 14.7) / 14.7 = 3:1 C.R. 1,600 scfm / 3 = 533.33 cfm

4. Volume of pipe/cfm = time in minutes 21,991.2 / 533.33 = 41.23 minutes

5. Calculate for 80 psi: C.R. = (80 + 14.7)/14.7 = 6.44 C.R. 1,600/6.44 = 248.36 cfm 21,991.2 / 248.36 = 88.54 minutes

» FINAL ANSWERS = 41.23 minutes at 0.2 MPa (30 psi) and 89 minutes at 0.55 MPa (80 psi).

The correct answer to Test Your Skills on page 19 is b.

Some Shipments Dropped in December

The latest shipments data from the National Fluid Power Association shows decreases in pneumatic and mobile hydraulic shipments while industrial hydraulic shipments slightly increased in December when compared to November, according to raw index data. The year-to-date % change for total fluid power shipments in December was 16.6%, down from 16.9% in November. The data shows the 12-month moving average of shipments for pneumatics, hydraulics, and total fluid power continues to grow. Mobile hydraulic orders received from January to December 2022 are currently 103.4% of the orders received from January to December 2021. The charts are drawn from NFPA’s Confidential Shipment Statistics (CSS) program.

Hydraulic and Pneumatic Shipments

Raw Index Data, Index: 2018=100

Shipments – Cumulative year‐to‐date % change (2022 vs. 2021)

This graph of raw index data is generated by the total dollar volume reported to NFPA by CSS participants and compared to the average monthly dollar volume in 2018. For example, the December 2022 total dollar volume for pneumatic shipments is 106.7% of the average monthly dollar volume in 2018. (Base Year 2018 = 100)

The table above is expressed in terms of cumulative percent changes. These changes refer to the percent difference between the relevant cumulative total for 2022 and the total for the same months in 2021. For example, December 2022 pneumatic shipments figure of 8.5 means that for the calendar year through December 2022, pneumatic shipments increased 8.5% compared to the same time-period in 2021.

Pneumatic, Mobile, and Industrial Hydraulic Orders 12/12 Ratio

Each point on this graph represents the most recent 12 months of orders compared to the previous 12 months of orders. Each point can be read as a percentage. For example, 117.3 (the December 2022 level of the industrial hydraulic series) indicates that industrial hydraulic orders received from January 2022 to December 2022 were 117.3% of the orders received from January 2021 to December 2021. (Base Year 2018 = 100)

Total - Hydraulic and Pneumatic Shipments 12 Month Moving Average

This graph of 12-month moving averages shows that in December 2022, total fluid power, total pneumatic, and total hydraulic all increased. (Base Year 2018 = 100)
