The Path of Least Resistance I’ll bet most of us who have succeeded as engineers, technicians, or mechanics in fluid power can relate to spending the summers of our youth tearing apart bicycles and old strollers with the intent to build our next sweet ride. Possibly our dad or a retired neighbor showed us a few basics of mechanics and let us use their old tools. Or maybe a science or technology teacher, who let us get our hands dirty and build robots or tear apart small engines and refurbish them, inspired us. Encouraging young people to continue wrenching on things, to take science, technology, engineering and math (STEM) classes in high school and beyond, and eventually pursue a career in fluid power is a challenge. Your average teenager will take the path of least resistance, doing the absolute minimum to meet the requirements to get by. But instead of asking “How do we keep them from following this path?” maybe we By Marti Wendel, CFPS, CFPE, should ask “How can we make a career path in Territory Manager, The Paquin fluid power the path with the least resistance?” Company; Chair, Fluid Power Inspiring and mentoring are just parts of Educational Foundation (FPEF); the puzzle that prompts students to stay in the and VP of FPEF for the International STEM fields and possibly choose fluid power as Fluid Power Society (IFPS) their final careers. The Fluid Power Educational mwendel@paquin.com Foundation (FPEF) strives to encourage students to pursue a career in fluid power at all levels of development. Through the FPEF, scholarships are provided to high school students who have participated in FIRST, a robotics competition for grades 9-12 (www.usfirst.org). Persuading colleges and technical schools to offer classes in hydraulics and pneumatics with electrical integration in a hands-on learning atmosphere is also imperative. Through the Key School program, the FPEF has certified 18 colleges or tech schools and two high schools that meet these stringent criteria of hands-on classes within their fluid power curriculums. The FPEF also provides scholarships to Key School students who have demonstrated their dedication to fluid power and maintain the necessary GPA. In the past, grants for equipment have also been given to Key Schools. I am proud to be involved with the Fluid Power Educational Foundation as a board member for the past four years, donor, and currently as Foundation chair. The FPEF has been supporting students who are studying hydraulics and pneumatics for almost three decades. We currently have a nine-trustee board and are a standing committee of the International Fluid Power Society. The newly formed “strategic alliance” between the two organizations has already shown great promise. The FPEF is financially assisting individual students, which directly affects their potentials for success in fluid power, and we continue to look for ways to promote fluid power education to all ages, securing the future of fluid power innovation. Please join me in promoting careers in fluid power to today’s students. To learn more about FPEF or if you have interest in providing financial assistance, please visit the FPEF Web site at www.FPEF.org. We can also mentor a FIRST team, volunteer for an IFPS committee, educate people about the amazing careers where energy-efficient fluid power is used, or be the dad or neighbor who encourages the gang to include brakes on their freshly manufactured go-cart. If we hope to eventually bring well-trained employees to our personnel departments and exceptional resumes to our inboxes, those of us who have chosen this field need be advocates of our profession. We need to make sure young people of today are familiar or possibly even proficient with fluid power components and principles prior to choosing their career in fluid power, the path of least resistance. 4

For the last Air Teaser problem (Manufacturers Directory issue), you were to calculate the instantaneous SCFM needed for the valves and plumbing to handle. The answers were 14.78 SCFM for the extension and 6.42 SCFM for the retraction. This time, calculate the SCFM for the same following problem solving for what the air compressor needs to deliver: • • • • • • •

Cylinder is a 4" x 10" x 2" rod 2 second extension time 1 second retraction time 1 second dwell time Extension force is 800 lbs. Retraction force is 100 lbs. Dual regulators are used and the required pressure is 75% of regulator setting to cover inefficiency of the circuit. • The valve is mounted directly on the cylinder. The 75% regulator setting will cover for the lost of air in the air lines between the valve and cylinder.

(From Manufacturers Directory issue)

When working with pneumatic systems, it is important to know both the SCFM requirements when a cylinder is extending as well as retracting. However, the instantaneous SCFM can be much higher than the SCFM that a compressor needs to supply. Calculate the instantaneous SCFM the valve and plumbing need to handle for the following problem: • • • • • • •

Solution Extension F = PA: 800# / 12.566 in² = 63.66 PSI Calculate for inefficiency: 63.66 / .75 = 84.88 PSI Find Compression Ratio (CR): (84.88 + 14.7) / 14.7 = 6.77 CR Find volume of cylinder: V=AxL 12.566 in² x 10” stoke = 125.66 in³ / cycle X 30 cycles / min. = 3769.92 CIM / 1728 = 2.18 CFM X 6.77 (CR) = 14.78 SCFM to extend Retraction F = PA: 100# / 9.42 in² (EREA) = 10.6 PSI Calculate for inefficiency: 10.6 / .75 = 14.15 PSI Find CR: (14.18 + 14.7) / 14.7 = 1.96 CR Find volume of cylinder: V=AxL 9.42 in² x 10” stroke = 94.2 in³ / cycle X 60 cycles / min. = 5652 CIM / 1728 = 3.27 CFM X 1.96 (CR) = 6.42 SCFM to retract

ANATOMY OF A CYLINDER CUSHION

or the sake of this review, we are neither critics nor advocates but observers. A pneumatic cylinder propelled with gusto must soon stop or be stopped. The dart from a blowgun will exit the barrel and continue on a one-way flight. The piston and rod assembly in the cylinder must stop and be retracted to prepare for the next cycle. The common cylinder cushion traps compressed air and provides reduced end-ofstroke impact similar to automobile air bags. The economics of producing more with the same resources, people, equipment, floor space, etc., encourage faster cycle rates for automation and production equipment. This may require machinery and pneumatic cylinders to complete each stroke or cycle faster. Conventional flow (speed) controls for pneumatic cylinders limit the speed of travel. This also reduces the end-of-stroke impact but slows total average velocity. To cause the cylinder to go faster, simply remove the flow control or increase the flow rate through it. With “the need for speed,” any manner of decelerating or reduction of velocity adds time to the cycle. The cushion option that is available with many cylinders allows high speed for most of the stroke. The end-ofstroke impact is cushioned with trapped air. In Fig. 1 the piston and rod assembly of an air cylinder is propelled forward. The cylinder depicted has a rod end cushion. At this point, the exhausting air is unobstructed allowing high speed forward. In Fig. 2 the cushion spud [1] has entered the cushion seal [2] and blocked the main outlet flow. Exhaust flow will

divert to the small passage that may be controlled with a needle valve [3] or fixed orifice. In Fig. 3 the piston has made full travel and bottomed against the head of the cylinder. Cushioned impact deceleration avoids violent crash stops. In Fig. 4 the pressure is reversed to retract the cylinder piston and rod. Another function is the reverse flow check valve. This allows free flow to put pressure on the face of the piston quickly. Without it the cylinder may be slow getting started until the cushion spud clears. One cushion design employs a seal [2] that acts as a check valve for reverse flow as well. Cushions are available for either end or both ends of most cylinders. If you have cushions and don’t like them, take out the cushion seal. You will see the difference. Electronics can control the exhaust flow from a cylinder with greater sophistication, but the ubiquitous, venerable, mechanical cushion abides.

The Little

Leaks That Keep Men Poor By Brendan Casey, HydraulicSupermarket.com

With more storm clouds appearing on the economic horizon, it’s now more important than ever that every dollar spent on operating and maintaining fluid power equipment is a dollar well spent. Furthermore, it’s imperative that the fluid power equipment you design, repair, or maintain doesn’t leak money. Hydraulic systems are often considered perennial consumers of oil and in turn, make-up fluid is an inherent cost of operating hydraulic equipment. But to calculate the real cost of one or more “minor” leaks on a hydraulic machine, the expense associated with all of the following need to be considered: • Make-up oil • Clean-up • Disposal • Contaminant ingress • Safety

Make-Up Oil

The cost of make-up oil should be the most obvious cost of hydraulic system leaks. I say “should be” because many hydraulic equipment users fail to consider the accumulative effect on the cost of one or more slow leaks over time. Consider a piece of hydraulic equipment losing 0.5 cc of oil per minute. That’s 30cc per hour, and 720 cc over 24 hours – perhaps not a significant loss. But over a month this equates to 22 liters (263 liters over the course of a year). Assuming an oil cost of $3 per liter, the annual cost is around $800.

Clean-Up

Where there are oil leaks, there is almost always a clean-up cost to consider. Clean-up costs include • labor; • equipment required to empty sumps and drip trays, and degrease machine surfaces; and • consumables such as detergents and absorbent material. Assuming it costs $20 per week in labor, equipment, and consumables to clean up the piece of equipment discussed above, the annual clean-up bill totals more than $1,000.

Disposal

I can remember a time, not so long ago, when waste oil companies used to pay for the privilege of emptying waste oil tanks. These days they bill you to take it away. Environmentally acceptable disposal of waste oil and absorbent material containing waste oil costs money. Assuming transport and disposal cost of $1 per liter, the annual disposal costs attributable to the leakage rate discussed above amounts to $263.

Contaminant Ingress

Where oil leaks out, contaminants such as air, particles, and water can get in. Costs to consider here include:

www.fluidpowerjournal.com | www.ifps.org

• component damage and fluid degradation as a result of contaminant ingress, • downtime caused by equipment reliability problems, and • removal of ingested contaminants.

Safety

In many situations, oil leaks can pose a safety hazard. Like the costs associated with contaminant ingress, the costs associated with the hazards posed by oil leaks are difficult to quantify—short of a lost time accident actually occurring. However, active management of the safety risk posed, through for example, more frequent clean-up than may otherwise be necessary, skews this cost to a quantifiable area.

Adding It Up

The annual cost of oil leaks on the hypothetical piece of hydraulic equipment considered above amounts to over $2,000 per year in make-up fluid, clean-up, and disposal costs alone. As you can see, if multiple pieces of hydraulic equipment are involved, the accumulative cost over an extended period of time can be significant. But what about hydraulics’ fluid power cousin, pneumatics? One of the advantages that pneumatics has over hydraulics is its clean-ness. Trouble is, air leaks are much easier to ignore than oil leaks because they don’t draw attention to themselves in the same way. You don’t need to worry yourself with clean-up and disposal costs. Contaminant ingression is possible, but is generally not a major concern. And unless the leak is significant, safety is not usually a big issue either. So that leaves make-up fluid (air).

Make-Up Air

While air is free, clean and dry compressed air is not. In considering the cost of make-up air for a pneumatics system, the following need to be considered: • Depreciation (wear and tear) of the compressor • Conditioning costs: filtration, drying and lubrication • Energy cost of compression The ideal leakage rate is of course zero, but when calculating the free air delivery (FAD) required by a pneumatic system, a rule of thumb is to allow for leakage of 10% of total flow rate. Consider a 10 cubic meter/minute system leaking one cubic meter/minute. The power required to compress one cubic meter (35.3 cubic feet) of air per minute to a pressure of 6 bar (90 psi) is approximately 5.2 kW. At an electricity cost of $0.10/kWh, this leakage is costing over 50 cents per hour in energy costs alone. In a 24/7/365 operation, that amounts to $4500 per year!

Quantifying Losses

While a leakage rate of 10% of flow rate may sound high and would be unsustainable in a hydraulic system, air leakage rates as high as 25% are not unheard of, even in apparently well-maintained pneumatic systems. The actual leakage rate of a system can be calculated using the following formula:

QL = QC x t/(T + t) Where: QL = System leakage rate (cubic meters/minute) QC = Compressor FAD (cubic meters/minute) T = Time between compressor cut-out and cut-in (minutes) t = Time between compressor cut-in and cut-out (minutes) In a case study I read about recently, the pneumatic systems of two plants were surveyed for leaks using ultrasonic leak-detection equipment. In the first, a small plant, which took two hours to survey, 27 leaks were discovered. The calculated energy cost of these leaks was $9,000 per year. In the second, a much larger plant, which took two days to survey, 260 leaks where discovered. The calculated energy cost of these leaks was over $90,000 per year! This amount of waste should never be allowed to occur, especially not in the current economic climate. Don’t let it happen on your watch.

FIG. 1: Very long cylinder rod undergoing coating process

A Brief Overview Of Corrosion-Resistant Piston Rod Coating Technology

he large hydraulic cylinders used for dam gate and other valve opening and closing applications typically are expected to last from 30 to 50 years. In recent years, however, an increasing number of hydraulic cylinders are failing in the field due to piston rod corrosion. A fairly common example is the failure of plasma spray coated piston rods cited by the U.S. Army Corps of Engineers Engineering Construction bulletin on Jan 15, 2009. Unfortunately, laboratory tests do not predict the complete failure modes for these brittle mechanically bonded coatings. When rod coatings are compromised, they expose the rod substrate to corrosion attack. Corrosion can occur in a number of forms such as uniform, pitting, crevice, galvanic, stress, or other types. Piston rod coatings are difficult to repair and replace when they fail. It usually can be done, but in most cases it is an unplanned expense that requires special approval and can take months of coordination and execution. Once approved, typical times for the actual repair can be anywhere from three weeks to several months.

Piston Rod Coatings

Electroplated hard chrome coatings can be applied to the surface of piston rods in various thicknesses. Chrome acts as a wear-resistant coating with good lubricity partly because numerous micro-cracks in this coating help capture hydraulic oil, which improves rod seal lubrication. Those micro-cracks, however, also are passageways for the atmosphere to gain access to the base material. Plasma spray piston rod coatings are applied with a spray gun that impinges the powder on to the sub10

Tech Directory 2011

the substrate, and cause piston rod distortion. Fusion clad coatings generally are not as hard as plasma and thermal coatings, but when applied properly with the correct choice of coating material, they provide excellent corrosion resistance.

Other Factors

Coated piston rods need to be finished to produce a surface roughness profile that will optimize rod and seal life without compromising the coatingâ&#x20AC;&#x2122;s anti-corrosion properties. Surface finish parameters including average maximum profile height, bearing ratio, skewness, and some others need to be carefully specified and controlled to assure optimum performance in the field. Application-specific structural integrity considerations, including the diameter of the rod and the material from which it is fabricated, also influence the selection of coating technologies and materials. For example, a long-stroke piston rod can bend with its own weight due to piston rod sag creating microcracks in brittle coatings. The duty cycle also must be considered. Some applications require constant motion while others need only a few cycles a day or even less. In hydropower applications, seasonal variations typically play a role on the extent and frequency of stroke. Every application has its own set of challenges including static and fatigue generated by shock, vibration, side load, eccentric loading, torsion, and buckling. In addition, factors like rod orientation, length and diameter, temperature, geographic seismic requirements, as well as the rules of governing bodies such as the Det Norske Veritas (DNV), ABS, DV, Lloyds, and others, all have a influence on the coating choice and performance.

strate. The speed of the deposition process results in a porous, lamellar grain structure with particles being flattened at the site of impact on the piston rod surface. In most cases sealants are used to close the porosity. Plasma spray coatings are generally brittle. Since they are mechanically bonded, factors such as substrate cleanliness, kinetic energy, temperature, powder properties, cooling rates, and others all influence bond strength. Thermal spray piston rod coatings such as HVOF (High Velocity Oxy-Fuel) use an oxygen fuel mixture that is ignited in a combustion chamber and propelled with the powder on to the piston rod surface at high kinetic and thermal energy. The coatings generated are usually denser and less porous and brittle than plasma spray coatings. Although adhesion is better than plasma spray, these coatings are still mechanically bonded and typically exhibit a lamellar grain structure. Plasma transfer arc (PTA) welding and laser cladding both create a fusion weld attachment with the piston rod surface that has excellent adhesion. The deposited metallic coating is far more ductile than plasma or thermal spray coatings. This gives it an ability FIG. 2: Laser coating of a cylinder rod to absorb impact and handle abrasive scratches without adjacent cracking and bending from long piston rods. The PTA process imparts more heat to the surface than laser cladding, which can affect coating hardness, increase iron pickup from

The Coating Certification Process

Meeting the Joint Industry Project’s (JIP) “Guideline For Qualification Of Wear And Corrosion Protection Surface Materials For Piston Rods” through the joint industry standards 3247 and 3295 is the “gold standard” for Highly Corrosion-Resistant Alloys (HCRA). Eaton’s recently completed DNV certification of its Eatonite™ laser cladding as an HCRA provides an example of how the process works. Eaton started by performing extensive powder coating and application technology testing and analysis to identify the combination that optimally addressed customer requirements. Results were evaluated for robustness of cladding processes, corrosion resistance, coating hardness, ductility, process control, and metallurgical evaluation. Most of the pre-evaluation work was done in conjunction with the DNV laboratories in Høvik, Norway, and Columbus, Ohio. Through this process, Eaton developed its own exclusive powder and proprietary laser application processes to optimize cladding performance. The DNV certification was divided into three key phases. In the first phase, DNV reviewed the background documentation related to the technology and the manufacturing procedure specifications. As a part of the certification basis, a critical parameter list was developed. Typical documentation included • design basis including description of the technology, functional limitations, and main data,

• • • • • • •

reliability targets and acceptance criteria, reference of applicable codes and authority requirements; principles of storage, transportation, installation, commissioning, operation, maintenance, and abandonment; interface requirements; environment; functional loads; principles of manufacturing and quality assurance; data sheets for chemical pre-treatment products and masking material where applicable; and coating applications (including control of essential process parameters and instrument settings).

The purpose for this phase was to understand and review the documentation of the critical parameters and overall certification plan, and identify key challenges and uncertainties. The second phase of the certification process consisted of on-site audits of the coating procedure during the manufacturing and finishing process. During the onsite audits, a review of the quality control measures and acceptance criteria for the finished Eatonite clad coating was conducted. The purpose of this phase was to ensure that the coating tested during the certification was representative of the metallic cladding. The final phase confirmed that the functional requirements and target reliability/functionality as stated in the guideline can be met through the battery of prescribed tests per JIP 3247. Eatonite successfully completed all three phases and was certified as the

first, and to date the only, cylinder coating to fulfill the “Guideline For Qualification Of Wear And Corrosion Protection Surface Materials For Piston Rods.” In practical terms, that means the coated cylinder rods deliver the mechanical performance of traditional SAE 4130 steel piston rods, combined with the corrosion resistance expected for materials like Inconel 625, giving customers the best attributes of both materials. The involvement of international organizations like DNV working cooperatively with industry leaders promises a new generation of HCRA coatings. Corrosion may be an inevitable natural process, but new materials and technologies like Eatonite are giving engineers and end users improved tools for the fight to control it.

How much coal does that valve burn? Richard F. Bullers, CFPPS Senior Applications Engineer SMC Corporation of America

Back when gasoline was 35 cents a gallon, the term “environmental technology” was not well known. Engineers did not often promote the benefits of building low-energy consumption pneumatic valves among their peers. Recycling or conservation of resources was seldom discussed with any seriousness. In reality, the conversation was more likely to have turned to the muscle cars of the day and how much horsepower they would generate. This “bigger-is-better” philosophy not only produced big block engines with three carburetors, but also pneumatic valves with large direct solenoids and bulky steel construction. Then one day some of us woke up to find out the meaning of an Arab Oil Embargo. Suddenly the thought that our energy supply was cheap, plentiful, and secure evaporated. A typical pneumatic solenoid valve of that era may have consumed 6 Watts of power and lasted 10 million cycles. Today a pneumatic valve can be operated with power consumption as low as 0.1 Watt with a life of over 200 million cycles. This is an amazing 60 times less energy with 20 times the life. How is this now possible?

The Transition to Modern Valve Design

As industrial automation produces ever more sophisticated machines with the advance of robotics, benefits of weight reduction and power conservation in pneumatic valve design are beginning to find their role in a larger strategy of environmental technology. Optimizing solenoid valve design may seem a trifle affair when compared to reducing gasoline consumption for an automobile, but every unnecessary ounce of material and unit of energy expended have a collective and negative impact. The vast majority of energy used to manufacture and operate virtually every modern object we use every day is electricity generated from coal.

The Transferable Benefits of Energy Conservation There are over 600 coal-fired electricity plants operating in the United States today. A typical 500-megawatt coal plant will discharge 10,000 tons of sulfur dioxide; 10,200 tons of nitrogen oxide; 720 tons of carbon monoxide; 125, 000 tons of ash; and 3,700,000 tons of carbon dioxide in addition to tons of other disagreeable waste products.1 We don’t need an alarmist to remind us we do not want ourselves or our children breathing pollution, but this issue is often as invisible as the air. It’s not just asking about what we can change over the next decade, but how our very next decision in regards to purchasing and applying pneumatic valves can work to both our immediate and long term advantage.

Power Amplification T h e S o l e n o i d / P i l o t Va l v e

One technique that dramatically lowered the energy consumption of a pneumatic valve was using the concept of flow amplification. A very small 3-port, 2-position, direct-solenoid valve is used to operate a much larger air-operated valve. The small soleCommon Pressure Supply noid results in low power consumption (Fig. 1). To Main & Pilot Valve At the heart of this transformation is the development of advanced design direct solenoid valves that are diminutive in both size and power consumption. The solenoid pilot valves have also undergone specific design changes to improve their performance and use less energy. As valve design evolved, materials changed from zinc die cast to anodized aluminum, to engineering plastics. This has resulted A B in valves with streamlined shapes and lower mass. The internal passages, spool and sleeves, and poppet designs changed to increase flow capacity. The advent of serial communications systems that use coded signals to operate individual solenoids on banks of EA EB valves mounted together on a common manifold has elimiLarge Air Piloted Main Valve nated cumbersome wiring harnesses and improved electrical efficiency. Now entire networks of valves can be controlled, monitored, and programmed from a remote location. 14

The long-term benefits of reducing energy consumption are the short-term rewards that can be realized by machine builders, maintenance personnel, plant managers, or anyone applying pneumatic valves. The most immediate profit for end users is from a reduction in electricity consumption, but for everyone there is a strategic advantage gained from the “transferable benefit” created. Transferable benefits are gains you make that can be passed along to your customers, shareholders, employees, or anyone in general. It is a reduced cost, a “green machine,” a reputation as an environmentally conscious company that can boost a bottom line, beat a competitor machine’s operating costs, or gain business from public awareness. Imagine competing on a reduction in operating costs by positioning yourself as an energyefficiency leader in your industry. In conclusion you might wonder; how much coal does that valve burn? Twenty times, thirty times, sixty times more then it needs to? Look at the valves you have in service, compare your energy costs, and explore your alternatives. An epiphany can not only be enlightening, but also profitable.

The replacement of old energy-inefficient pneumatic valves can be done as part of a major overhaul or simply as a replace-as-needed strategy. This also provides several opportunities. One is to check the valve to ensure it is not oversized. Another is to conduct an energy audit. Energy audits are an effective tool in identifying waste and making a plan for corrective action. According to Hank van Ormer, Air Power USA, Inc., “Compressed air conservation and optimization programs in any compressed air system will generate significant energy savings opportunities, plus probable improvement in productivity and quality.”2 You’ve been changing to energy-efficient light bulbs in your house, so why wouldn’t you change the same old valves you’ve been using all these years? Check the power consumption of any valve product you have in service and ask if there is another way of doing the same job with less energy. When purchasing a valve, ensure the flow capacity and valve function are correct and make it a “trifecta” by getting the lowest wattage valve possible. for energy-efficient machines. 2 Shop What do you do when you buy a water heater, stove, refrigerator, air condi-

tioner, furnace, or virtually any other appliance? You look at the Energy Star3 rating, of course. Ask the machine builder to explain what the power consumption of their machine is and how their product was designed with energy savings in mind. If you are contracting with a machine builder, make low power consumption one of the stated design goals. Ask them for a return on investment analysis for operating costs versus machine purchase price. This will provide incentives for manufacturing a machine that will pay for itself in a reasonable amount of time and help you determine if the price is right.

How can cost savings from the application of pneumatic valves be achieved? energy-efficient pneumatic valves 1 Apply whenever possible. Where previously a valve may have used 6 Watts to operate, the same valve now could be operated for a 10th of a Watt. This is an amazing 60 times less energy use. Not all applications can reduce their energy consumption by this amount, however significant gains can be made with a modest amount of effort.

Build energy-efficient machines. the correct amount of air pressure. 3 For 4 Use a machine build, this sounds like a naïve statement, but in reality it is Pressure is energy and energy is money. Using more energy than required

simply a matter of using a straightforward approach, technical challenges notwithstanding. The lines are not always clearly drawn between practicality, manufacturing costs, or competitive advantage, however there are basic techniques that can be applied. A lwa y s c o n s i d e r a m e c h a n i c a l a d v a n t a g e . The amount of motive power necessary to do any task can be greatly reduced by the use of gears, levers, springs, and other practical mechanical devices that reduce the force required to achieve the work required. U s e p o w e r a mp l i f i c a t i o n . A low-power valve can be used to operate a larger air-operated valve to advantage in many applications.

This type of valve only requires a momentary signal to shift and can remain for very long periods of time in an actuated position. • A “UPS” system (uninterrupted power supply) may be a better alternative as part of a redundant safety system than relying on the interruption of continuous power supplied to a solenoid valve to initiate a stop sequence.

for a single actuator adds up over time. Producing more pressure in a plant than is necessary multiples the effect. • Consider “check type” regulators or using a check valve in parallel with a standard regulator to reduce pressure for the non-working stroke of an actuator that only requires high force in one direction. • Check load ratios and actuator sizing carefully to reduce unnecessary consumption. • Reduce the volume between directional control valves and actuators to eliminate waste and improve response time and control. • Reduce the compressed air pressure for the entire plant if only one or two applications are running at a higher pressure by using air intensifiers at point of use. the use of “air blow” applications.

High-Speed

Fig. 1: Appearance and structure

Linear Servo Valve

Development of the High-Speed Linear Servo Valve

Hydraulic controls are commonly used in mechanical drive systems for industrial equipment and machinery. In addition to the actuation of mechanical systems based on electric commands, they typically employ electro-hydraulic servo valves or proportional electro-hydraulic directional and flow control valves with sensors for position, speed, acceleration, pressure, and load control. The “high-speed linear servo valve” from Yuken Kogyo Co., Ltd. replaces conventional nozzle flapper-type electro-hydraulic servo valves. Incorporating a newly developed voice coil linear motor as a control actuator, the valve has been put into commercial use. The valve has been designed to provide a frequency response of 400 Hz or more, which is approximately twice that of nozzle flapper-type servo valves (100 to 200 Hz). It is intended for use in forging press machines. For commercialization, the valve has also been designed to offer long service life, high reliability (tolerance to hydraulic fluid contamination), and energy savings. It has been applied in a wide range of areas because of its performance and reliability.

Structure and Operation

The valve controls the flow and direction of hydraulic fluid by moving the spool for flow passage control. With the spool coupled directly to a compact, high-thrust voice coil linear motor, the valve operates under electrical feedback control using a dedicated high-speed amplifier. The valve structure is shown in Fig. 1. The valve comprises a body, a linear motor, and a position sensor, with a highpower neodymium-iron-boron (Nd-Fe-B) permanent magnet placed in a fixed position and a movable coil out of contact with the permanent magnet and the yoke. The position sensor is a noncontact high-response magnetic sensor. The valve has a simple structure and lightweight movable parts; it is user-friendly with high response and tolerance to hydraulic fluid contamination (allowing for a contamination level of NAS class 10).

Type

Specifications and Performance

The valve has been adopted in applications with a maximum operating pressure of 5,076 psi and a flow rate of 1 to 1,004 GPM. It supports a wide range of flow rates, performance requirements, and functions. Basically, the valve is a single-stage servo valve configured as described above and operates at a flow rate of 1 to 10.6 GPM, a frequency response of 450 Hz/-90°, and a step response (0 <=> 100 %) of 2 msec. At higher flow rates, the two-stage type of the valve is employed and operates at a frequency response of about 100 Hz/-90° and a step response (0 <=> 100 %) of 8 to 12 msec (representative performance).

Applications and Commercial Results

Because of its high response, the valve is used in injection molding machines that deliver a resin filling speed of 1,000 to 1,500 mm/sec in 8 to 12 msec and die casting machines that deliver an aluminum filling speed of 4 m/sec or a magnesium filling speed of 8 m/sec. Since the valve has excellent following capability, it is also used in various testing machines. The valve with tolerance to hydraulic fluid contamination is useful in steel-making facilities. The total sales volume of the valve since 2001 has been about 10,000 units.
