AS I REFLECT upon this year with Fluid Power Journal thus far, my mind travels back to last fall when we were planning for the 2019 Editorial Calendar. We set three goals—the first of which was to reach out to more of fluid power’s ever-increasing markets such as civil engineering, food processing, and the medical industry. We quickly realized that we needed to publish the Fluid Power Journal monthly in order to engage these markets. It would also guarantee that there would be no communications gap with our subscribers. We also decided to increase the frequency of our digital offerings to a monthly basis as well.

Another goal that we had was for the Journal to increase its relevance to the fluid power audience by “telling our clients’ stories.” We embarked on an aggressive Sponsored Content program with both print and digital offerings. We added new features such as the Component Showcase section that focuses on a specific product category, and the Ask The Expert section, where companies can share their expertise on a particular topic so as to help our readers solve their problems. We also rejuvenated our white paper and video programs with dedicated pages on our website, www.fluidpowerjournal.com.

Additionally, we started a very popular Targeted Display Advertising program that reaches out to the fluid power audience

COMPRESSED AIR SYSTEMS

Compressed Air Maintenance

By Ron Marshall, Marshall Compressed Air Consulting

»

LIKE ANY INDUSTRIAL equipment, the air compressors, dryers and associated components on your compressed air system need occasional attention. It is very tempting to stay out of that dark, hot and dirty compressed air room, especially if the air compressor is running trouble-free, but maintain the system you must. Maintenance intervals can be stretched for a while, but it usually comes back to haunt you in the end, like the old Fram oil filter commercial says, “Pay me now or pay me later.”

If you have compressors that run continuously, you need to be especially diligent. It is often quite easy to relate the oil changes of your compressor lubricant to the oil changes for your own personal vehicle, thinking infrequent oil changes are acceptable, but for a compressor that runs all the time, it is important to ensure the lubricant stays in good condition, requiring timely changes to

air at high pressure, exposing it to the negative effects of oxygen. The oil is also used as a coolant, carrying away the heat of compression. It captures particles of dirt that are sucked into the compressor and get past the inlet filter, reducing its quality. And it traps the condensed moisture that forms when air is compressing, contaminating it further.

Compressor lubricants have additives to prevent oxidization and to extend its life in these harsh conditions, but these measures only last for so long. Once the lubricant reaches the end of its lifetime, if pushed beyond normal, damaging deposits will start to form inside the compressor that will clog up bearing and cooling surfaces with varnish. Its only a matter of time before overheating, bearing wear, and oil carryover cause major rebuild costs, or worse, the total failure of the compressor.

A HYDRAULIC PILOT-OPERATED PRESSURE RELIEF VALVE Relief valves are used to limit maximum pressure in hydraulic systems. When system pressure begins to exceed the pressure setting of the relief valve, a controlled amount of hydraulic fluid by-passes through the relief valve to the tank port and limits the system pressure to the valve setting. The two basic types of relief valves are direct acting (simple) and pilot operated (compound).

Several important terms must be understood with respect to the operation of relief valves. These are: cracking pressure, full-flow pressure, and reseat pressure.

• Cracking pressure - pressure at which the poppet valve unseats.

• Full-flow pressure - pressure at which a relief valve diverts full flow to the reservoir.

• Reseat pressure - pressure at which a relief valve closes after being open.

In a simple relief valve, a spring holds the poppet against a seat. When system pressure is high enough to overcome the spring force, the poppet moves off the seat to allow fluid flow through the bypass. The spring compression is set so that the poppet opens to divert sufficient flow to limit the pressure to the preset value.

In a compound relief valve, a light spring holds the main stage piston so that the discharge port is normally blocked. A small amount of fluid flows past the main stage piston through an orifice in the main piston to the pilot stage of the relief valve. The pressure of the fluid on the pilot valve exerts a force on the pilot valve poppet. If the force exceeds the spring force, the poppet is unseated, allowing a small amount of fluid to flow through the drain. The vent port on a ventable pilot-operated remote control valve may be used as a remote control or plugged if not used.

The pressure drop resulting from flow past the pilot valve poppet is experienced on the back side of the main stage piston, and the piston shifts, opening the valve. In operation, the compression on the pilot stage spring is adjusted so that the main stage piston opens at a specified pressure.

As with all precision machined components, care must be exercised when assembling a pilot-operated relief valve. Cleanliness is of the utmost importance. Components, particularly the balanced piston, should be lubricated with clean oil prior to assembly. The cap or pilot section of the valve must be carefully aligned over the piston. Some relief valves use locator pins to ensure alignment.

Bolts must be torqued properly. Operation of the valve should be tested before placing the valve back in service. If the valve fails to function properly due to piston binding, the cap may be loosened and tapped gently to achieve proper alignment. Bolts must be retorqued following this adjustment. 

POSITION SENSORS

Enable Next-Gen Hydraulics and Robotics Working in Extreme Environments

By Mike Marciante, Business Development Manager, NewTek Sensor Solutions

Hydraulic and robotic systems are performing more often in areas with temperature, pressure, and radiation extremes. Withstanding these environments is the goal for the next generation of instrumentation and sensors these systems rely on. Many hydraulic and robotic systems require linear position sensors that operate reliably under continuous high pressures and temperatures while fitting into restrictive spaces.

Hydraulics with linear sensors used in oil drilling and material testing now operate in temperatures sometimes exceeding 400°F (204°C), and pressures approaching 30,000 psi (2068 bar). Robotics and automated equipment in nuclear power plants and clean-up zones operate in radiation environments now exceeding 30 MRad. For the next generation of hydraulic and robotic systems, LVDT linear position sensors offer many benefits—chief of which is excellent measurement quality—while operating reliably in high temperature, pressure, and radiation exposure.

LVDT TECHNOLOGY THAT MAKES IT POSSIBLE LVDTs are non-contact sensors, meaning that the housing containing the windings and the core never need to touch. This frictionless operation gives LVDTs infinite mechanical life, making them ideal for applications where replacement costs can be high and long-term reliability is key.

Available with a lightweight, low-mass core and a compact diameter as small as 0.188 inches (4.7 mm), LVDTs can be miniaturized, well-suited for high-response dynamic measurement required in hydraulic and material testing systems where space is at a premium.

Beneficial when compared to other linear position sensing technologies, LVDTs are AC-operated with no on-board printed circuit board (PCB) for signal processing or conditioning, allowing them to operate in very high pressures. In vented designs specialized for embedding in hydraulic systems, holes expose the coils inside the sensor to the fluid.

Since the sensor is completely immersed, even rapid spikes in pressure will not cause damage to the LVDT during operation. Any fluid to which the LVDT is exposed must be electrically non-conductive and chemically benign, which is a very common trait among hydraulic fluids and oils, so vented LVDTs are compatible for immersion into most hydraulic systems.

The absence of on-board electronics enables production of these sensors with radiation-hardened materials that will not become brittle or decay when exposed to radiation. These are able to withstand total integrated flux of 30 MRad, and even 100 MRad in some cases.

OCTOBER 2019

TAKING ROBOTICS INTO RADIATION “HOT” ZONES Renewed interest in nuclear safety and space travel for governmental and commercial purposes will send more robots to places with elevated radiation exposure.

Rovers, tools, and other robotic machinery traveling through space or in orbit may encounter direct sun exposure and radiation without the protection of the Earth’s atmosphere. When they are commissioned into service, accurate position feedback is key from robotic actuators that are controlling sensitive operations, experiments, or repairs. Radiation hardened LVDTs operating in vacuum and cryogenic conditions are rugged and dependable enough to survive the journey into space. While there, they deliver high quality position feedback with infinite resolution and fast response times, as is often required by these systems.

Radiation-hardened robots are working here on Earth too. They have been used to clean up contaminated sites all over the world, including present-day Ukraine, Japan, the U.S., and throughout Europe. Sites of nuclear incidents and retired uranium enrichment plants have all benefited from robots going in areas where humans cannot. These robots gather information to create maps of hazard zones, while also transporting or breaking up contaminated debris and fuel rods. Actuators and position sensors enable their legs, working arms, and grippers. Radiation-hardened LVDTs coupled to these actuators deliver a fast position feedback response to the robots’ controls, allowing them to move very precisely and smoothly.

Built to withstand even heavy exposures to 100 MRad, the use of these position sensors can help prolong the service life of these robots, often tasked with projects spanning years or decades.

WWW.FLUIDPOWERJOURNAL.COM • WWW.IFPS.ORG

DEEP BELOW THE SURFACE Oil reserves are now being extracted from previously inaccessible locations. Access to these reserves involved exposure to temperatures and pressures legacy machinery could not withstand. On next-generation multi-directional drills, LVDTs are being used to deliver position feedback used to accurately control the actuators setting the drill’s direction. Within existing wellbores, multi-finger calipers are used to accurately profile the walls to identify signs of fatigue or abnormalities. Multi-finger calipers extend their arms to make contact with the walls.

Within the caliper, the fingers are mechanically linked to an LVDT that measures their position as they travel through the bore. The LVDT readings are transmitted to the surface so the wellbore can be accurately profiled. Each of these critical operations employ LVDT position sensors designed to be embedded in hydraulic fluid up to 30,000 psi (2068 bar) and over 400°F (204°C). Because of the reliability of LVDT technology, the sensor itself can remain operational for the lifetime tools and equipment that use them.

The ability to remain rugged and reliable with an infinite mechanical life, as well as high temperature and pressure designs, have made LVDT position sensors the preferred selection in the most demanding and cutting-edge requirement in robotics and hydraulics. 

Sheet Metal to Egg Crate Foam –

SELECTING THE RIGHT

Vacuum

CUP

By Mike Parzych, Product Marketing Manager, IMI Norgren

Vacuum – the difference in atmospheric pressure on one side of a vacuum cup and the other – has been used in robotics and traditional manufacturing for decades to move objects and materials. Now collaborative robots (cobots) are making automation more affordable and accessible for smaller, more versatile operations like mixed product assembly or order fulfillment, creating more opportunities than ever to use vacuum. And where there is vacuum, there are vacuum cups to connect the vacuum source with the object being moved. So how does one select the right cup?

Cup size and type

Vacuum can lift all sorts of materials, even those with rough or uneven surfaces, if the right cup is used.

Force equals pressure times area To begin, there are three basic factors to consider when using vacuum: force, pressure, and area. Force is the weight of the object being moved, multiplied by a safety factor. Pressure is the expected vacuum level – the negative pressure or suction created by the pump. Area is the size of the contact between the vacuum cup and the object. This is where vacuum exists.

The basic calculation, Force = Pressure x Area, defines the starting point for choosing a cup and using vacuum to move a load.

Non−porous objects For flat non-porous surfaces like this rigid plastic bowl, a flat vacuum cup does the job.

The force generated depends on both the vacuum level and on the area. The vacuum pump generates the suction and the cup transfers that power to the object. Both vacuum level and cup configuration are variables a designer can control. The larger the cup, the lower the pressure required of the pump, meaning less energy is consumed to generate the vacuum. Conversely, increasing the pressure delivered by the vacuum pump makes it possible to use smaller cups if needed to accommodate the shape of the product being picked up.

10

OCTOBER 2019

Cups sizes are identified by cup diameter, so once the desired area is known, refer to manufacturers’ specifications for the appropriate cup size. Differences in application requirements can guide a decision between using a large diameter cup with a lower vacuum level or a smaller cup with a large vacuum pump (for example, to meet space or size limitations).

Cup types include bellows, multi-bellows, round oval, flat with or without cleats, and cups with removable fittings or permanent fittings.

To choose the right type of cup, consider the characteristics of the object being picked up.

Is it non-porous or porous? Is it flat, irregularly shaped or flexible? In general, use flat cups for flat objects and bellows cups for irregular objects. Every situation is unique, but some examples of typical materials in industrial applications serve as a starting point.

To use vacuum for picking up objects with solid, non-porous surfaces, knowing force, pressure, and area is enough. The vacuum is created and contained between the cup and the object and full force is achieved and maintained until the vacuum is released. Examples of non-porous materials include steel, glass, laminated chipboard, and rigid plastic. Flat cleated cups are widely used for non-porous applications because the rigid, low-profile design means they resist peeling away. Some non-porous objects, for example large sheets of thin metal, may bend slightly. In a case like WWW.FLUIDPOWERJOURNAL.COM • WWW.IFPS.ORG

this, using multiple pliable bellows cups ensures that all the cups make full contact with the sheet as it bends.

Porous or uneven surfaces These may include corrugate, woven materials, or objects with extremely rough or uneven surfaces. When handling porous materials, it is important that the flow path between the object and the vacuum pump is large enough to allow the pump to draw in the air that leaks through the surface (e.g., cheesecloth) or from gaps between the cup and the surface (e.g., corrugated cardboard). Because no complete seal is formed between the cup and the object, free air will continue to flow through the pump.

Different combinations of vacuum pumps and bellows cups can be used to lift porous materials like this cardboard. The pump needs to be large enough to draw in the air that continues to flow through the porous surface, but oversizing a pump wastes energy.

The balance here is generating the required vacuum force and flow, and optimizing compressed air consumption. There are a variety of pumps and cup types to help optimize flow, but in the end, it often requires trial and error to fine tune a process to the right flow.

Flexible materials When handling flexible materials, for example wraps used in packaging, it is critical that the pump cup, fitting, and vacuum line are large enough to handle the required flow. Flexible materials wrinkle, causing large, unpredictable leak paths. The cup and pump must be sized to accommodate a high leak rate.

The bore of the fitting must be close to half the diameter of the cup to allow for large flows.

The good news is that, typically, flexible materials are not heavy. Calculating cup holding force precisely may not be required. A cup with a very thin, flexible lip will more easily conform to the wrinkled material. Multi-bellows cups work well because they are so flexible.

With so many variables involved with flexible materials, consider sending a sample of the material to a cup supplier for testing so they can make pump and cup recommendations.

Versatility Vacuum cups can be made from a variety of materials. Some popular materials include vinyl, polyurethane, chloroprene, nitrile, silicone or natural rubber. Each material has different working temperatures, durometers, and resistance to oil or water.

Vacuum is extremely versatile and can be used to do things no other technology can do. It is highly controllable and since it exerts negative pressure instead of pushing WWW.IFPS.ORG • WWW.FLUIDPOWERJOURNAL.COM

Flexible materials like this plastic wrap wrinkle, allowing substantial unpredictable leakage.

A bellows cup with a thin, flexible lip will more reliably conform to the material.

Vacuum is highly controllable so it can be used to lift delicate, irregular objects as easily as large, heavy materials.

or pressing, it can be used to move delicate or irregular materials as well as large, heavy objects. Today’s wide variety of cup designs, sizes, and materials means that designers can access the advantages of vacuum for a wider variety of applications than ever before. 

M+PTE TECHNICAL MEETINGS MONDAY, OCTOBER 14 1:00 PM – 5:00 PM TECHNICAL SESSION I: APPLICATION, DESIGN, AND RATING MODERATOR: JASON DAUBERT, FLSMIDTH, INC. Electric Vehicle Transmissions with Hypoid Gearset (19FTM01) Dr. Hermann Stadtfeld, The Gleason Works This paper presents a new design concept which utilizes a super reduction hypoid with a ratio between 8 and 15.

Misalignment Compensation Splines Design (19FTM02) Davide Marano, Ferrari (Italy) Crowned spline teeth are frequently used to avoid interferences between

shaft and hub teeth. Currently, a precise determination of the misalignment and crowned teeth influence on spline load capacity can only be performed by finite element method, (FEM), or other powerful numerical simulations. This paper proposes an analytical model.

Spline Centering, Piloting, and Toggle: Torsional Stiffness, Shaft Bending, and Centering of Moment Loads (19FTM03) Steve McKenny, General Motors Company Common practice for a splined joint is to assume that the load is theoretically transmitted along the entire length of the tooth face, but several factors, including axial spline length and the ratio of hub to shaft torsional stiffness, can impact how the load is distributed along the tooth face.

Optimal Polymer Gear Design: Metal-to-Plastic Conversion (19FTM04) Dr. Alexander Kapelevich, AKGears, LLC Unlike machined metal gears, polymer

gears produced by injection molding allow for a deep optimization of gear tooth macro and microgeometry.

Design of a Double Spiral Bevel Gearset (19FTM05) Horácio Albertini, CEFET MG, Federal Center of Technological Education of Minas Gerais (Brazil) The most common bevel gear geometries are straight, spiral, and helical (skew), and all these types of gearset subject the bearings to three types of forces, namely: axial, radial, and tangential. This paper presents a double spiral bevel gear design.

Specific Dynamic Behavior of Planetary Gears (19FTM06) Burkhard Pinnekamp, RENK AG (Germany) This paper describes theory of noise generation in a gear mesh and the specific application on planetary gear systems.

The results are illustrated by an example with test bench measurements.

Idler gear sets affect gear whine by phasing the meshes. This paper shows how, by cleverly selecting the number of teeth on the idlers, their tooth thicknesses, and the idler location, the forces from transmission error force vectors that must be reacted by the idler bearings can be substantially reduced, thereby reducing the excitation on the gearbox that causes noise.

Reduction of the Tonality of Gear Noise by Application of Topography Scattering for Ground Bevel Gears (19FTM09) Marcel Kasten, Laboratory of Machine Tools and Production Engineering (WZL) of RWTH Aachen University (Germany) Computing Gear Sliding Losses (19FTM10) Caleb Gurd, Eaton Corporation *2018 recipient of an AGMA Foundation scholarship.

This paper evaluates eight different algorithms available in the literature for determining coefficient of friction and calculating gear sliding loss, and their applicability to commercial vehicle transmissions.

Opportunities of Efficiency Improvement by the Use of Hydro Lubricants (19FTM11) Matthias Pfadt, Kluber Lubrication Muchen SE & Co. KG (Germany) The majority of industrial lubricants are based on mineral oils. Hydro Lubricants, which use water either as a base oil or as an additive, offer a more sustainable solution and are potential candidates for a wide range of industrial applications.

STRATEGIC VACUUM CUP

By Dane Spivak, Davasol

The following is an opinion article written by Dane Spivak of Davasol Incorporated, an industrial brand management firm with many clients. This article is written in partnerhsip with one client, Vacuforce LLC, based in Indianapolis, Indiana, USA.

INTRODUCTION

CONTROVERSIAL CUP SELECTION Depending on the product surface to be gripped or lifted, there are many different vacuum cups that can provide a good seal. If we consider a piece of glass, for example, there are thousands of cup models that can seal against its flat smooth surface. Alternatively, creating a cup seal on a bag proves to be more challenging and limits available choice. However, there are still many models that can do the job. So how do we choose the ideal cup?

More often than not, machine builders or vacuum cup users select a particular cup simply because it was readily available in stock.

The easy choice is to use a familiar model that is on hand, and as long as it provides a decent seal, all is well. So generally speaking, not much thought is put into this process. Then, the cup is implemented into the production line, but its durability might become a liability. Since

It is widely accepted and understood that vacuum cups are a consumable product by nature. A vacuum cup may last many months or only a day or two. Although vacuum cups in general are not often seen as a substantial corporate expense, they can possibly incur a larger cost than one would expect. This article discusses the significance of vacuum cup selection and how it ties into the overall cost within a business. We will also touch on how to select an appropriate vacuum cup model based on economic and production needs.

vacuum cups may need replacement—some as often as every day—using a long-lasting cup can be crucial, especially if you are a high-volume user. The following offers recommendations in strategy for identifying the best cups for the application.

BUILDING BLOCKS TO INCREASE CUP LIFE Vacuum cups come in all shapes, sizes, and materials. These features play an important role in the performance and longevity of the cups. Let’s start by analyzing the cup style.

Figure 1 shows three styles including flat, single bellows, and multiple bellows. Intuition tells us the flat cup provides a sturdier and more secure grip on the product whereas the multiple bellows cup is not as stable. The bellows creates more stress on the cup body and lip. This concept suggests that a cup with more bellows is typically not as durable. So to increase cup life, flat cups are ideal, or if possible, reduce the number of bellows.

The cup lip thickness affects its life too – refer to Figure 2. Since this is the point of contact with the product, it is certainly a critical factor. For the most part, thicker cup lips last longer. A vacuum cup will have its lip wear away until it can no longer provide a satisfactory seal. At that point, the cup needs to be changed. Lower quality cups can crack at the lip or bellows. This is an indication that the cup is not being used to its full potential as it is prematurely breaking instead of wearing away.

This is often referred to as work hardening.

Material selection is arguably the primary characteristic in determining cup durability. Various cup materials are used, but the most commonly supplied are foam, vinyl, silicone, NBR, and polyurethane. This is in respective order of average cup life from shortest to longest; foam being the quickest to wear and polyurethane, arguably, the most durable. The cup features influence each material, though considering like-for-like models this rule of thumb applies. The product being gripped can also “fight back” against the cup material and cause it to wear quicker. For example, chemicals or high/low temperatures can reduce the cup life of NBR or polyurethane, and so silicone may offer longer life instead since it has a high chemical resistance and temperature range.

The quality of material can have a tremendous influence on cup durability. Numerous suppliers manufacture the most common industry models, however, each offers different life expectancies.

This is due to the quality of material, manufacturing techniques, and mold conditions.

A quick note about color. The color of a vacuum cup does not affect its life as it is simply a dye used in the manufacturing process. This is often misunderstood as specific materials tend to be linked to their common dye color.

COST VS DURABILITY PARADOX Everyone likes a good deal to save money.

Each purchasing decision is an investment and the price tag is usually front and center.

However, our obsession with getting the best deal can often cloud the big picture results.

Vacuum cups, being a wearable item, gives us a new perspective and approach to its investment. Table 1 compares three different cups and their yearly financial impact.

Total Yearly Cost = Cost Each x Yearly Usage Cup1 = $6.00 x 1200 = $7,200 Cup2 = $10.00 x 400 = $4,000 Cup3 = $18.00 x 300 = $5,400 Table 1 suggests that Cup2 is the best investment. Although it costs more than Cup1, it lasts longer so the overall yearly cost is lower. Cup3 offers better durability, but its increased life expectancy does not outweigh the overall yearly cost compared to Cup2. So in this closed parameter analysis, we can crown Cup2 as the winner.

However, there are other effects on vacuum cups that can come into play.

DOWNTIME IMPACT All manufacturing sectors experience downtime or scheduled maintenance, and everyone has the same interest: minimize the occurrences and time frames. Depending on the industry and manufacturing process, the impact can be drastically different. A large company that runs a three shift, 24-hour operation, with each process relying on one another for productivity, would value downtime much more.

Let’s first consider how to reduce downtime when physically replacing a vacuum cup. One key feature can make a significant difference.

Figure 3 shows two types of vacuum cups. One

with a loose fitting and the other with the cup molded to the fitting. The loose model offers a distinct advantage for replacing cups as it can be pulled off the fitting, then have a new one pushed back on—an easy, quick interchange. However, the molded cup assembly fitting needs to be unscrewed, and of course, the new cups need to be threaded in and tightened with a tool: a lengthier process by comparison, which can be quite time consuming when replacing multiple cups on a few tools. Pull-off-and-push-on cup assembly fittings are ideal for ease of maintenance and should be used if possible. However, molded cup assembly fittings are sometimes all that is available particularly for larger vacuum cups.

There are many contributing factors, but the primary costs of downtime include production loss, labor costs, and time. Table 2 uses the same data from Table 1 to compare the three cup models. In this example, we will consider all cup models to have equal time needed for interchange, and therefore the frequency of changing out the cups determines downtime cost.

Downtime Cost = (Production Loss + Labor Cost) x Interchange Time Production Loss = $1,300 per hour Labor Cost = $200 per hour Interchange Time = 1 hour Downtime Cost = ($1,300 + $200) x 1 = $1,500 per interchange Yearly Downtime = Downtime Cost x Number of Yearly Interchanges Yearly Downtime Cup1 = $1,500 x 12 = $18,000 Yearly Downtime Cup2 = $1,500 x 4 = $6,000 Yearly Downtime Cup3 = $1,500 x 3 = $4,000 Contrary to Table 1, Table 2 suggests that Cup3 is the better financial choice. Not only that, but less frequent cup changeouts create peace of mind. The human and reliability aspects can incur their own set of costs.

THE LIABILITY OF RELIABILITY Reliability of a vacuum cup is arguably the most important feature. We discussed cup life, which over time can be very predictable, but what

WWW.FLUIDPOWERJOURNAL.COM • WWW.IFPS.ORG

about instances when cups fail unexpectedly? It’s a rare occurrence, but cups can fail due to external influenced damage, cracking, falling off its fitting, and other situational anomalies. In turn, it can result in damaged product, broken machines, and even worse, injured workers. These are considered “what-if” scenarios and are generally immeasurable, but should not be overlooked.

For the most part, cups with higher durability are usually more reliable. But it is important to choose a cup that offers a confident seal, and ensure the machine is adjusted and designed to work effectively with the chosen cup. Table 3 includes a reliability cost associated with the points discussed above and demonstrates additional cost savings with Cup3. It also provides an understanding of the potential large gap in overall costs between Cup1 and Cup3.

It is difficult to designate a specific dollar value to reliability cost as it is unpredictable and can incur larger values from a single incident. Our theory is that cups with shorter life pose greater liability and therefore will result in higher costs.

The following example is a hypothetical situation for each cup model based on a five-year period.

Yearly Reliability Cost = (Total Production Loss + Total Machine Repairs)/Time Time = 5 years Cup1 Total Production Loss = $48,000 Cup1 Total Machine Repair = $12,000 Cup1 Yearly Reliability Cost = ($48,000 + $12,000) / 5 = $12,000 per year average Cup2 Total Production Loss = $16,000 Cup2 Total Machine Repair = $4,000 Cup2 Yearly Reliability Cost = ($16,000 + $4,000) / 5 = $4,000 per year average Cup3 Total Production Loss = $12,000 Cup3 Total Machine Repair = $3,000 Cup3 Yearly Reliability Cost = ($12,000 + $4,000) / 5 = $3,000 per year average

HIGH-PRODUCTIVITY MINE INVESTS IN HYDRAULIC DRIVES

By Ashok Amin, Hägglunds, Market Segment Manager, Bosch Rexroth

The air is filled with dust, and the large, heavy rocks pound the equipment hard. Only the toughest survive at the Aitik mine. Boliden therefore takes great care in selecting suppliers for its new crushing plant.

“We make sure we only use suppliers that have experience in this field. This applies to all the investments we have made in recent years, but this project has given us the best results so far,” says Jörgen Larsson, Project Manager at Boliden.

OCTOBER 2019

Visitors to Sweden’s biggest open-pit copper mine are greeted with an impressive sight in Gällivare.

The entire Empire State Building could stand on the floor of the mine without reaching above its rim. Way below, some of the largest machines in the world are crawling about: excavators with a bucket capacity of 45 cubic meters and rock trucks capable of

carrying more than 300 tons, with wheels that are a full four meters in diameter.

The ore deposits in Aitik contain a copper ore called chalcopyrite, as well as some gold and silver. The ore is refined to produce a concentrate that feeds Boliden’s own smelting works. The rock waste, or overburden, is removed from the pit and sold for road-building and concrete production, for example.

Aitik is not only the largest open-pit copper mine in Sweden, but also the most productive in the world. This is thanks to largescale production, highly efficient methods, and a high degree of automation.

“We can process more low-grade ore than many other mines because of our efficiency. We actually have lower input levels than many other mines have in waste,” says Larsson.

WWW.FLUIDPOWERJOURNAL.COM • WWW.IFPS.ORG

STRATEGIC INVESTMENTS FOR GROWTH The Aitik mine has set a long-term goal to raise production from 36 to 45 million tons of crushed ore by 2020.

To achieve this growth and improve the consistency and reliability of production at the same time, Boliden has invested in a completely new crushing plant with two spindle crushers. In its annual report, the company states that this massive investment will ensure “more reliable production planning, lower maintenance costs, better predictability and better profits.”

“Right now we are getting a good price for what we produce. That gives us the opportunity to invest.

But one big challenge is that we are greatly increasing the area of mining, which also involves high costs. We constantly have to finetune our mining operations so that we can increase production using our existing equipment. The new crushing plant will enable us to do that,” says Larsson.

Obtaining the permit to expand also placed big demands on the ecological sustainability of the Aitik mine.

“We are leading the way environmentally. This will allow us to ramp up production. The measures we have taken range from electric vehicles to energy recovery and

ecological compensation areas,” shares Larsson, who stresses that the company is constantly raising its commitment to the environment.”

a plant to be proud of Larsson has a great deal of experience in the industry. He has done everything from operating mining machinery to supervising maintenance and installation. He has supervised the crushing project and been involved in commissioning.

“It’s fantastic that we have been able to invest in a totally new plant, where everything is well-planned and we have plenty of access to the equipment.”

Larsson is especially pleased with the completely new feed system.

“We originally had inclined apron feeders. They were unreliable in every way. These are the first conveyors that are completely horizontal. And they look great!”

The feed system was designed by Metso in the U.S., and is a proven design with many systems already in use around the world. Metso Minerals adapted the system to suit the particular needs of the Aitik mine. This work was done in close collaboration with Bosch Rexroth, which supplied four CBM hydraulic Hägglunds motors.

WWW.IFPS.ORG • WWW.FLUIDPOWERJOURNAL.COM

CURIOUS ABOUT HYDRAULIC DRIVE One of the reasons why Boliden decided to invest in apron feeders with direct hydraulic drive was frequent problems with gearboxes. Another was curiosity.

“We had many gearbox breakdowns over the years and wanted to improve availability. This will be a test of hydraulic technology. I have seen Hägglunds drives in various reference installations around the world, and during my investigations, I did not hear of any negative experiences. My visit to the factory in Mellansel was also incredibly interesting. I gained a new understanding of how hydraulic systems work.”

In addition to improved availability, Boliden set high demands on the performance of the equipment.

Then, Metso drew up a specification of requirements based on two motors that share the load on each feed unit, with a capacity of 8,000 tons per hour, a variable speed of 0–7.46 rpm and a starting torque of around 1,000,000 Nm. The solution offered by the Hägglunds specialists at Bosch Rexroth was two CBM 2000–1400 motors per apron feeder. It was a welcome solution that easily met the requirements.

“We wanted to have some power in reserve, so that’s good. It gives OCTOBER 2019

SUCCESS FACTORS FOR THE PROJECT us a maximum capacity of 9,000 tons per hour. It also gives us redundancy for all the main components, so we can drive with one motor if needed,” explains Larsson.

The new plant was commissioned in June and the Aitik mine is now running at full production capacity.

“After a few weeks of testing, we went on summer vacation. I was away for five weeks and everything

worked perfectly! The plant has now processed more than six million tons of ore and there has not been a single incident. The fact that production is running so smoothly at this early stage is an excellent result. Especially when the plant was custom-built specifically for our needs.”

The drive systems take up minimal space and allow fast replacement of components, thanks to the splined couplings.

Larsson reckons they make installation incredibly easy.

“The main benefits are that we have improved availability while reducing maintenance costs. The hydraulic drives provide better access from the sides and make the plant easier to maintain. The way things are looking now, we won’t need to work on them, but

if we do have to replace anything we have really good access.

Another big advantage is that we can reverse the hydraulic drives during maintenance.”

All that remains to do now is a few small adjustments and performance tests. Boliden will take both crushers and drive systems up to maximum load and check that they produce the tonnage required. A big part of the performance testing is to ensure that the plant can meet availability targets over the course of a month.

“It all looks good so far. If this turns out well and gives us improved reliability, we will probably use hydraulic drive technology elsewhere. For our big conveyor systems in particular, the Hägglunds drives are definite contenders,” says Larsson with satisfaction. 

FIGURE IT OUT

New Problem:

Noisy Pump Causing Foam to Escape Through the Filler Breather

olution to the previous problem: Ink Mixing Machine Speed Problems

S

By Robert Sheaf, CFPAI/AJPP, CFPE, CFPS, CFPECS, CFPMT, CFPMIP, CFPMMH, CFPMIH, CFPMM, CFC Industrial Training

The source of the problem of adjusting the speed of one mixer blade and how it affects the speed of other blades turned out to be the compensator setting on the pump. It was set at 1,000 PSI and just needed to be set an additional 100 PSI to resolve the issue.

Apparently, due to the lack of good documentation, when the pump was replaced, the team set the speeds and pump pressure to what worked for the normal consistency inks and not for the occasional thicker mixtures.

»

I WAS CALLED to troubleshoot a foaming problem on a system that had the pump-motor unit mounted on top of the tank. When I got there, I was surprised that a root beer-like foam indeed was oozing from the filler breather cap and the pump was very noisy. Closer inspection showed that the foaming was worse when the pump was unloaded back to tank. I felt the pump noise was caused from the foaming problem, and the pump shaft seal showed a slight leaking problem when the unit was turned off.

Any idea what’s the cause of the problem?

By Travis H

As automation expands across a variety of industries, the performance required of actuators becomes more diverse in terms of loading and speed. In some situations, it can be difficult to determine whether pneumatic or hydraulic actuators are the optimal choice. Air/oil tandem actuators are a compromise that can provide characteristics of both pneumatic and hydraulic operation.

In cases where lighter payload capacity or force output is needed, pneumatics may be preferred due to low operational costs. Pneumatic actuators may also be able to cycle faster than hydraulic units. However, the compressible nature of air limits how well the speed of pneumatic actuators can be controlled. Additions such as flow controls can help through metering the exhausting air, but erratic motion can still result from operating pneumatic actuators at low speeds.

Since liquids are virtually incompressible, hydraulic actuators can be operated reliably at lower speeds with smooth motion. This controlled operation lends itself to better energy handling. Hydraulic actuators can also be supplied with greater pressures, producing more force than pneumatic counterparts.

In most cases, however, hydraulic operation requires greater initial and operational costs than pneumatic options.

WWW.IFPS.ORG

Some applications require a combination of pneumatic and hydraulic benefits, pointing to air/ oil tandem units as the ideal option.

These tandem units are pneumatically operated, providing modest force output at an efficient cost. The inclusion of oil results in motion resembling that of a hydraulic unit, allowing greater speed adjustability and controlled motion. By incorporating both air and oil, tandem units eliminate disadvantages that come from using purely pneumatic or hydraulic options.

For linear motion, an air/oil tandem cylinder would be used.

The construction resembles two cylinders that are joined head-tocap with a common piston rod. The bore of one cylinder is pneumatically

driven to extend and retract the piston rod. The head and cap of the other cylinder are plumbed together, and the bore is filled with oil. As the rod extends or retracts, the oil flows from one side of the piston to the other. This results in consistent linear speed and evenly applied force through the entire stroke. An air/oil tandem cylinder can be useful in vertical stroke applications where gravity could cause excessive acceleration of a load being lowered and eliminate the need for an external stopping method.

Rotational motion can also benefit from the inclusion of oil. The construction of an air/oil tandem rotary actuator is a double-rack rotary with a cap that connects the two bores on one side of the pinion. This configuration only achieves the torque of a single-rack Cylinder Air-Oil Tandem

Rotary Air-Oil Tandem

rotary as one side of each rack is used for oil communication.

As a rack is pressurized, the oil flows from one bore to the other via the shared cap. The torque is applied evenly through the rotation, resulting in consistent rotational speed. This smooth motion is ideal for rotations in the vertical plane in which the load’s center of gravity passes over the pinion. An air-only rotary used in this case could experience compression of the exhausting air when the mass descends, resulting in undesirable acceleration of the load and a high-energy impact. The introduction of oil avoids the compressibility issue and is a viable alternative to using a rotational counterweight.

Integrated flow controls and check valves provide the ability to set the speed in each direction of travel of an air/oil tandem unit.

An oil reservoir is used to ensure a constant supply of oil to the actuator. Retaining a pressure head to the oil reservoir prevents improper displacement of oil and retains the oil within the tandem unit. The oil portion of the actuator must be properly bled before use as air trapped within the oil could result in the sporadic motion that an air/ oil tandem unit is used to avoid.

The addition of oil into a pneumatically driven unit is a cost-effective option to eliminate issues that may arise from the compressible nature of air. Air/oil tandem actuators are ideal when pneumatic operation and force output must meet the speed control and steadiness of hydraulics. ď Ź OCTOBER 2019
