Forged Strong to LaSt Long. From continuous casters and melt shops to hot and cold mills to galvanizing lines and coke plants, Yates Cylinders are working hard in all areas of the steel industry— designed and manufactured to stand up to the rigorous environment these cylinders must endure every day.

Yates works closely with many companies to help solve their cylinder failures, first determining the cause and in many cases recommending upgrades for a rebuilt cylinder. This process not only eliminates the original problem, it also offers an extended life for the cylinder at a fraction of the cost of a new one.

High heat, debris and dirt are some of the factors our series of Mill Duty, Tie Rod and Round Body Welded cylinders overpower daily in a steel mill.

With three regional locations offering full service capabilities (engineering, welding machining, grinding and assembly) and around-the-clock service, Yates is one of the largest and most complete cylinder manufacturing and repair companies in the country.

Notable Words

IFPS Membership -What Do You Make of It? I am sometimes questioned about the IFPS logo on my shirt. Once I was asked if it was a symbol for some type of “secret society.” This gave me a chuckle and the opportunity for a short elevator speech, but it also gave me pause for thought. I happily explained that the International Fluid Power Society is a non-profit organization that works to promote education, training, and professionalism in fluid power through certification. I also explained that I am a member and chair the committee for membership and chapters. This prompted a quizzical look from the other person and the question, “Fluid power?” I went on to say “hydraulics and pneumatics,” and while doing so, in the back of my mind I was thinking…maybe we really are a secret society. When you use the IFPS logos, stickers, lapel pins, lanyards, and other membership emblems, you are inviting questions and creating the possibility of helping someone advance in this industry. It is good to explain that IFPS benefits include discounts for training, certification, test fees, and even discounts for drug prescriptions and rental cars. It doesn’t hurt to talk about the Fluid Power Journal, professional networking, professional development points, and the free study manuals and web seminars, but of even greater value is explaining how your membership affords you the opportunity to help others. Maybe the curious person asking these questions is also involved in fluid power, but not certified. You can help them. Perhaps their teenage child is involved in a FIRST robotics program, or perhaps their recent graduate is struggling to find a career path. Volunteering to help a FIRST team or educate the younger graduate about careers in fluid power gives you other opportunities to “pass it forward” and realize great personal rewards. We are here to help you with these initiatives. The IFPS board meetings are held twice a year, and during these meetings, the Membership and Chapters committee, along with our other committees, work with ideas to help improve the membership experience, create useful tools, recognize our members, and expand our presence. Some of our recent accomplishments include the following creations: ƒƒ A discounted membership rate for active military – reduced annual and two-year membership renewal fees. It’s our way of saying “thank you” to those who serve. ƒƒ Individual membership brochure – a handy overview of IFPS and membership form that explains what we do. This is a great tool to have. (Please contact IFPS staff and ask for some.) ƒƒ Fluid Power Professionals Day – a day to thank you for all you do as a fluid power professional. Lots of details in this Journal (page 6) or at ƒƒ Chapter start-up guide – a step-by-step instruction manual for community-service-minded individuals to start up an IFPS chapter. Chapters have additional financial benefits and serve as an outreach to the community through schools, other service organizations, and local industry. ƒƒ Chapter operations manual – an organizational aid and guide to running your chapter. We have more plans for the future, but it is you—the individual IFPS member— who can really make a positive difference in the lives of others. IFPS membership…what do you make of it?

henever the term “mechatronics” is discussed among fluid power professionals, it seems that each person has a different opinion as to its meaning. These opinions stem from the varied interests of those who use them, and it makes a single, clear definition difficult to obtain. The intent of this article is to develop a clearer definition of the term and then to see where fluid power training and certification fit in. The term “mechatronics” originated at the Yasakawa Electric Company in the 1960s. The name comes from combining the terms “mecha” from mechanics and “tronic” from electronics. It was used to describe the necessary integration of electrical control with mechanical systems when accuracy and repeatability were needed. Over time, the term came to include the five most recognized areas of engineering: mechanical, electrical, telecommunication, control, and computer. Mechatronics is still an emerging “concept” of engineering concerned with the design of complex systems for sustainable manufacturing.

We will define a mechatronics system as a multi-disciplinary engineered process for sustainable manufacturing. You may have noticed that fluid power engineering is not included in the common understanding of mechatronics. This is because, for the most part, fluid power systems are considered part of mechanical engineering and so are relegated to a sub-heading. This is unfortunate. It diminishes the awareness of the need for training in fluid power as part of any career path toward mechatronics. The fact is that, for many sustainable manufacturing processes, fluid power is the best method for energy transfer. A mechatronics engineer without proper fluid power knowledge may not have the necessary tools to design the best system, and the mechatronics technician without fluid power education will be ill equipped to maintain, trouble-shoot, or repair even a well-designed system.

12 • March/April 2015 •

So, 1) what does mechatronics have to do with fluid power, and 2) what does it have to do with fluid power technicians, the people who service these systems? Before attempting to answer either question, it is necessary to examine what constitutes a mechatronics system. As used here, the term “system” will generally include some kind of mechanical process, sensors for signaling and conditioning operations, adjoining circuitry, a controller, some kind of input from an operator, and all with a view to sustainable manufacturing. The diagram in Fig. 1 represents a large automated assembly line. The chart is read in a clockwise direction. The process begins at the point of input, which may be some form of human machine interface (HMI). This interface could range from a simple start switch to a touch screen. The input signal is then transmitted to a controller, which could be a personal computer or a programmable logic controller (PLC). There are other types of controllers, such as a proportional-integral-derivative (PID) controller, which could serve as the brain of the system. The controller sends out command signals. If the system has what is referred to as an “open loop,” there will be no feedback of information as to what is actually happening during the manufacturing process. In closed-loop systems, sensors and switches provide feedback information. Feedback is used by the controller to determine the state of the system—whether or not the various functions are operating according to specifications. Feedback can also be used to measure proximity, temperature, and velocity. Feedback can make machinery safer and more efficient because it allows the controller to compare what is actually happening to what is supposed to be happening. Therefore, many, if not most, systems are closed loop. The command and feedback information is generated in two forms: digital and analog. A digital signal is a physical signal that is a representation of a sequence of discrete values. In an analog electrical signal, the voltage, current, or frequency of the signal may be varied to convey the information. Commands from the controller are usually in digital form and must be converted to analog in order to be understood by the devices they are meant to control. Likewise, the analog information coming back from the sensors will need conditioning before it can be understood by the controller. The mechanical system includes the mechanism that physically contacts the workload and may include belts, chains, pulleys, etc. The mechanical system pushes and pulls or turns a movable load, and this is where the “actuator” comes into play.

The actuator does the work by pushing, pulling, or turning, and is often a fluid power cylinder, rotary actuator, or motor. These are not the only kinds of actuators used. Some designers are specifying electric devices, such as electric cylinders, to do the job. These electric actuators (sometimes the combination of a ball-screw driving mechanism and servomotor) are capable of generating large amounts of thrusting force with precise control of speed and movement. Electric actuators may have advantages over fluid power actuators in certain circumstances, but fluid power actuators, with greater power density, speed, and flexibility, are still widely preferred.


What does mechatronics have to do with fluid power?

Obviously those servicing these systems must have broad knowledge, covering multiple disciplines, including fluid power.


What does mechatronics have to do with the fluid power technicians?

Fluid power technicians need to include mechatronics in their training if they are to service machinery whose maintenance and upkeep are determined by uptime. By referring back to the chart in Fig. 1, it is easy to see that a technician needs basic electrical skills, knowledge of electronics, programming, as well as other skills taught

for machine maintenance. These are the minimum skill sets needed to service this equipment efficiently. Since engineering and modern machine maintenance are both involved, two approaches to education and accreditation are needed. One should be based on a specialized mechatronics curriculum for fluid power engineers and another for fluid power technicians. There is a great degree of crossover between the two disciplines, but the technician does not need all the knowledge of an engineer to be successful working on such systems. Likewise, an engineer does not necessarily need to know a great deal about the performance of machine maintenance. Engineers and technicians both need special skill sets that match education to job requirements. Therefore, two distinct career paths should be recognized by two-year and four-year institutions. Since mechatronics is still developing, there will continue to be attempts to define and apply it across multiple disciplines. It is necessary that the fluid power industry continues to grow with this emerging technology.

Product Review







Designed for use in a broad range of applications, including those in wash down and caustic environments, these cylinders are constructed of 303 and 304 stainless steel. They include a Nitrile rod wiper to keep potential contaminants from penetrating inside the cylinder and are available with bore sizes from 3/4" to 2". Standard stroke lengths are from 1" up to 32" on some models. Other features include precision-rolled construction for a solid, leak-proof cylinder and an interchangeable design.

The company’s family of variable-speed fan controllers has been expanded with the addition of CE and CSA-certified EMC and EMC-6 controllers, which are fully potted, flame proof, and rated from -40 to +85°C. The EMC is an affordable drop-in solution for the mobile market that controls a single EFAN bank (multiple fans if connected in parallel) with fan diagnostic inputs, customizable J1939 CAN messages, bi-directional fan control, additional thermistor inputs, mini USB to PC communication, and free customizable GUI software. The EMC-6 hybrid controller allows independent control of five EFAN banks and one hydraulic fan, or six EFAN banks with fan diagnostic inputs.

The DS2R electro-hydraulic controller features proportional valve technology and replaces the DS1 model. It is fitted directly to the secondary control unit—axial piston equipment that can serve as both a pump or motor to manage variations in torque on winch drives in rotary AHC systems. The controller offers ƒƒ high dynamic response; ƒƒ precise, accurate motion so the loaded winch cable remains continuously “idle”—moving up and down only according to the winch, not the surface wave motion; ƒƒ energy efficiency through better control of hydraulic components, including the ability to use hydraulic accumulators to recover and reuse up to 70% of the secondary control unit’s installed power; and ƒƒ more reliability and easier maintenance, with a simpler design that eliminates a sandwich filter and is less prone to contamination.

PRIMING SYSTEMS BY DANIEL PASCOE, DAVASOL INC. alk into just about any private or government-run water pumping station where there is a need to pump water vertically from a lower level to a higher level, and seek out the most neglected and rust-covered piece of the equipment in the plant. You’ve just found a typical vacuum priming system as shown in Fig. 1. The rest of the equipment, including centrifugal pumps and a myriad of brightly colored valves, will gleam in comparison to this monster in the corner.


18 • March/April 2015 •

So what do we usually see when we look closely at one of these systems? They normally consist of one or two liquid ring vacuum pumps mounted on the top plate of a horizontal vacuum receiver tank, such as the one shown in Fig. 1. A simple control panel will be mounted on or close by this assembly, which offers a selector switch with basic on/off control buttons for pump “A” or “B.” As can be seen from Fig. 1, which has two liquid ring pumps side by side, there are pipes for feeding make-up water to the pumps. Usually the complete system has been leaking both sealing water and vacuum for years. Due to vacuum leaks, the system has usually been running almost continually, attempting to keep up with the required vacuum level set point. This is why it is severely corroded. Fortunately, technology has moved on, and water pumping stations no longer have to rely on water-sealed vacuum pumps (liquid ring pumps) for this type of application. The disadvantages of water-sealed vacuum pump systems include high maintenance costs, as well as excessive use of motive energy. In addition, the vacuum level can fluctuate considerably as the seasons change and the sealing water temperature rises and falls, directly affecting the vacuum level. With this type of variable, it takes a very specialized maintenance team to set up these systems and keep them operating with peak performance. So with that all said, what does a vacuum priming system actually do? Those great big gleaming water impeller pumps (as shown in Fig. 2) are great for moving high volumes of water from one place to another, but—and this is the thing—they are unable to pump or move air. When the pump is running and pumping water at tremendous volume, everything is working as it should. However, when the pumps are taken offline and stop, the water drains from the pumps by gravity. Consequently, they need to be filled with water (or other liquids) before they can be started again. This is where the vacuum priming system is used to “pull” water into the water pump to allow it to start. Fig. 3 shows a basic circuit with a duplex vacuum priming pump station connected in this particular case to two water pumps. The vacuum priming system creates a vacuum from the highest point in the impeller pump, right down to the level of the water reservoir (lake, catch basin, ocean water inlet, etc.) that needs to be pumped. The vacuum pump system removes the air from the water pump suction line, as well as from inside the water pump chamber. As the air molecules are removed, the water from the reservoir is pushed up through the piping and replaces the void (lower pressure area) that this air previously occupied. A priming valve, which is mounted at the highest point on the water pump, is the connection point for the vacuum line that is running from the vacuum system to each of the water pumps. There are several types of priming valves, but the most common contains a float that automatically shuts off the vacuum suction line as soon as the water raises the float. This prevents water from reaching the vacuum pumps. Either a separate sensor or a connection from the priming valve indicates to the pump station operator that the pump is primed and therefore safe to start the water pump drive motor. All of this sounds simple enough, but there are limitations to the height that a vacuum system can raise water, and that is usually regarded as a maximum of 10 meters. This distance is one of the principles of vacuum theory. The atmospheric pressure on our planet is 1,013 mbar (or 1 bar or 14.7 psi). For every 1 m of water depth, a pressure of 100 mbar is generated. Therefore, at a depth of 10 meters, the pressure is 1,000 mbar (or 1 bar or 14.7 psi). That’s a fact no matter where you are. At sea level, which is the lowest point on our planet, a full 1,000 mbar of atmospheric pressure is available. Therefore, a pump station at sea level can pull water up a distance of 10 meters (or 32.8 ft). If the pumps are higher than that, the water will not reach the pumps.

As a result, pumping stations in cities such as Denver, Co., a city known for being high above sea level, must be closer to the water source, as the atmospheric pressure is lower and less “vacuum” is available. The vertical distance from the top of the water priming valve (and/or the vacuum pump) to the lowest level of the water to be raised must be known in order to select a vacuum pump with sufficient vacuum depth capabilities. This important factor should be taken into account when calculating the vacuum depth requirement in a pumping station that is required to raise water from a reservoir with fluctuating water levels or when pumping seawater from a tidal basin to a desalination plant. When selecting a suitable vacuum priming system, it is necessary to consider not only the height that you wish to raise the water, but also the speed that you wish to accomplish the task. In an emergency, it is quite usual for several suction lines to be evacuated in quick succession. Therefore, not only is the maximum vacuum depth capability of your vacuum pump system important, but you must also calculate the speed of evacuation. This is normally determined by the pumping speed of the vacuum pumps selected for each individual system, and in North America, pumps are selected according to their cubic feet capacity per minute (cfm). Your vacuum pump specialist would need to advise you regarding this, as the capacity of evacuation reduces in direct proportion to the vacuum depth. Every vacuum pump is supplied with operating curves that will show you the pumping speed at various vacuum depths. For general purposes, to calculate the evacuation of a vessel (suction pipe and water pump) within a given amount of time, we use the following formula:

Vessel Volume = V ft3 Time = T (minutes) Pressure = P2 (in Torr) Starting Pressure = P1 (In Torr) Pump Capacity = C (cfm) C = (V/T) In (P1/P2)

In this formula, vacuum is shown in Torr, which represents mm of mercury (mmHg). Torr is used because it is an absolute pressure scale in vacuum measurement. Today’s vacuum priming system looks nothing like the old rusting liquid ring systems of old. A modern vacuum priming system will still contain two vacuum pumps mounted on a vacuum receiver vessel, but this is where the similarity stops.

As shown in Fig. 4, the modern vacuum priming system typically uses an oil-lubricated rotary vane vacuum pump. This pump will have an operating vacuum level in excess of 29"Hg for evacuating water suction pipes to significant vertical depths. In addition, the capacity of the pump selection can be varied according to how fast you need to accomplish the task. The benefit of the oil-lubricated pump is the reduced motive power. Reduced motor hp = less energy costs. As sealing water is no longer required, leaks are a thing of the past. There is no water wastage and no more external rusting of the system. A modern electronic control panel complete with a graphical touch screen enables the operator to select the desired operating mode to suit his anticipated needs. The system will automatically lead/lag or cascade the pumps on and off to offer equal operating hours, and minimum run timers will prevent the motors from overheating. Purge cycles will pump out vapor trapped in the system and prevent rusting of internal components and contamination of the lubricating oil. Visual and remote alarm systems are normally included within a basic system. A frequent option is an auto-drain system that will automatically evacuate any moisture that may find its way back to the vacuum receiver vessel, even when the system is in full operation. In the event of a catastrophic failure of one of the vacuum priming float valves, an electro-pneumatic valve will automatically isolate the vacuum circuit, preventing the vacuum priming system from flooding. In today’s energy-conscious world and in industrial facilities where unplanned maintenance calls costs thousands of dollars an hour in lost production, key steps for ensuring a reliable and cost-effective solution include making sure the vacuum pump priming system does exactly what it should and understanding what the user expects.

NEW INSTALLATION VIDEO SHOWS PROPER MOUNTING OF ELECTRIC CLUTCH TO HYDRAULIC PUMP Ogura Industrial has created installation videos to help customers who may have questions regarding proper installation and mounting of electric clutches used on hydraulic pumps. The first video covers the installation of smaller torque clutches that are typically mounted to an L-shaped bracket with a hydraulic pump mounted onto one side of the bracket. The videos show the proper installation of the clutch field assembly to the bracket and the mounting of the clutch rotor/pulley along with the correct bolt tightening torques. The second video covers the installation for the higher-torque hydraulic pumps that can be found on fishing vessels, heavy-duty mobile applications, and marine generator sets. Most of these large clutches also require a universal joint attachment, and this video shows the proper mounting of the u-joint flange to the Ogura clutch. The videos are available at www. and on YouTube.

TEST METHOD Raises Performance Standard for Rod Wipers in Hydraulic Systems


irt ingression is a major cause of hydraulic system inefficiency, degradation, and failure. Although superior filtration systems exist and are used to limit exposure to contaminants, there are a number of locations in a typical hydraulic system that remain vulnerable. Breather ports, external couplers, and power shaft systems that drive hydraulic pumps, external motors, and cylinders are included among areas that may be compromised. This article describes a new, innovative test method developed by Hallite in cooperation with Milwaukee School of Engineering (MSOE) to assess the amount of dirt entering a simulated hydraulic system through the rod wiper located on the hydraulic cylinder. It will discuss why and how such a test method (or specification) for rod wipers was developed, as well as the test procedure and conclusion derived from putting four different wiper products to the test, setting a new standard for the future of testing rod wipers in hydraulic systems.

34 • March/April 2015 •



The Quest for Standardization The International Organization for Standardization (ISO) ISO 4406 provides a standard for rating contamination in hydraulic fluids. The standard establishes criteria that codes the amount of contamination for particles that are >4, >6, and >14 microns in size. Manufacturers of filtration systems and products use these codes to identify the level of protection that is provided by their products. The manufacturers of hydraulic components (valves, cylinders, pumps, etc.) use these codes to establish operational limits of contamination. However, hydraulic cylinder manufacturers struggle to define operational limits and deploy repeatable methods to prevent contamination ingression with any level of confidence. This is due to the axial movement of the rod, which plunges contamination into the cylinder and consequently into the hydraulic system. The key component that minimizes this from happening is the rod wiper. Prior to this project, the only standardized test to assess contaminant exclusion of rod wipers was SAE J1195. Though some of the elements of SAE J1195 were valid to replicate hydraulic cylinders, key components were missing that provided valid conditions to assess the effectiveness of a rod wiper. Since most hydraulic systems utilize multiple hydraulic cylinders to support linear actuation functions in the equipment, the potential for dirt ingression into the system increases exponentially. This fact makes a standard test method for dirt ingression prevention very important.

Specification MSOE utilized SAE J1195 as a baseline to begin development of a test procedure. This included the application of industry best practices compiled from the input and feedback of hydraulic cylinder manufacturers. After numerous trials and adjustments were conducted over an eight-month period to best simulate actual field conditions, a repeatable, verifiable test standard was established.

MSOE’s Fluid Power Institute™ built a test rig with the following rod wiper ingression test parameters: ƒƒ Test duration: 24,000 cycles (80,000 linear feet travel) ƒƒ Cycle rate: 0.25 Hz (10 to 10.5 inches per second) ƒƒ Stroke length: 40 inches total ƒƒ Test pressure: atmospheric ƒƒ Test temperature: 150°F +/-2°F ƒƒ Test oil: MIL-PRF-46170 ƒƒ ISO 12103-1-A4 coarse test dust

Procedure The test rod wiper was installed in the rod end of the cylinder housing along with a TPE-faced, two-piece rod seal (Hallite Type 16 profile) to simulate typical boundary lubrication that is found on the rod in standard cylinder applications. The hydraulic circulation fluid was heated to 150°F by heaters located in the reservoir, and the hydraulic fluid was circulated with the cylinder rod fully retracted (not cycling) until the temperature was achieved. The rod was then cycled through the dust chamber for the duration of 80,000 linear feet, and dirt content was measured in the oil reservoir via the particle counter (Fig. 1).

Test Results

The 520 wipers also provided a high level of protection against contamination when compared to similar competitor wipes. Review of the data shows the wipers (520 and 820) performed better during the entire test, allowing for less contaminant ingression than competitors. Both competitor wipers showed a higher degree of ingression as the test proceeded. Data suggests that the design and material combination for the wipers promotes best ingression protection with improved wear characteristics.

Conclusion The hydraulic cylinder manufacturing industry now has a valid test procedure for rod wipers. Developed through Hallite’s cooperation with MSOE, this new test procedure enables the highest level of accurately assessing and measuring dry dirt ingression available. It is a major leap forward, establishing a repeatable pattern for the industry’s innovation of future test methods focused on wiper technologies used in a wide variety of real-world operating environments. And it demonstrates the value of continued commitment to understanding and developing technologies to improve the effectiveness of hydraulic seals and how they interact. Test results are based on the conditions and methods as described in this article. Testing was completed by MSOE in cooperation with Hallite.

MSOE tested the Hallite 520 and 820 wipers against two competitors. Based on these results, the 820 wipers provided the most protection, allowing the least amount of contamination into the test fixture. Note: the 820 wipers utilize a secondary protective structure outboard of the primary wiper lip (referred to as “Umbrella Wiper Technology”), which accounts for the better ingression protection.

NFPA Updates

The NFPA Fluid Power Challenge Makes Some Very Successful “Firsts” Firsts: the first time you rode your bike without training wheels, the first time you spoke in front of a large audience, or your first year away from home at college. Many times, these firsts are not completely successful. That is not the case with the inaugural NFPA Fluid Power Challenge hosted at Joliet Junior College by Caterpillar Inc. and Industrial Hard Chrome on November 14, 2014. This event had 17 teams competing, which is impressive for an inaugural event. Teachers said that this event was “inspiring” and “the best way for them (students) to learn.” The Fluid Power Challenge is a skillsbased competition. Teams consisted of four students that were challenged to solve a re-

al-life engineering problem using fluid power. Awards were given to the winning teams in five categories: Best Portfolio, Teamwork, Best Design, Best Machine Performance, and Overall Champion. But in the end, all the students who participated were winners. They learned how to problem solve, work in a team, and solve a real-world-type problem. And for many of the students, this was a “first” for them, as well.

Phil McCluskey, Randy Peterson, Ron Shinogle, Mark Landers, and Patrick Crayhon of Caterpillar and Industrial Hard Chrome, and everyone at Joliet Junior College, worked to make this event a reality.

iment, and multivariate technique was used to investigate efficiency of the sensor. The result showed that the dielectric sensor was able to detect different levels of iron and ISO test dust contamination in hydraulic fluid. The dielectric sensor will benefit the fluid power industry by ƒƒ providing a low-cost means for detecting fluid contaminants on vehicles during operations,

ƒƒ eliminating the need for fluid sampling until a problem is detected, ƒƒ detecting potential problems early before catastrophic failure, and ƒƒ lowering maintenance cost and reducing downtime.

Figure It Out

New Problem

Excessive Pressure Drop on a Test Stand A hydraulic distributor designed and built a test stand with various sizes of sub-plates for mounting and testing pressure and directional valves. There were 10 sub-plates in all. They had a piston pump with a pressure compensator set at 4,000 psi and a volume adjustment with a range of 2 to 10 gpm of flow. A safety relief was used and set at 4,200 psi, as well as a kidney loop/cooling unit. The unit also had a flow meter on the main tank return line. The pump pressure and return connections were two-bar type manifolds with ½" SAE #8 quick disconnects, and each sub-plate also had ½" quick disconnects (QD) for hose connections. Sub-plates needing a drain and/or pilot pressure connections used ¼" QDs and hoses. They had a nicely designed hose rack for unused hose to drain. The QDs were the flat-face type to reduce the spillage typical of connecting and removing hose on a test stand. With this arrangement, they intended to plumb up the valve to be tested to an actuator. There was a motor and a single rod cylinder for completing the setup. In general, it was a fairly nice valve test stand. To test out the stand for performance, they mounted a new ISO-3 (D02) directional valve rated at 14 gpm with a 72-psi pressure drop. It


was mounted, and the hoses with the QDs were attached to the pressure and tank manifolds and to the motor. The valve was a blocked-centered, 3-position, 4-way with solenoids on both ends. With the directional valve in the blocked center position, they set the safety relief valve and adjusted the compensator. Next, they wanted to set the flow on the pump to its full flow of 10 gpm. They connected an electrical cord to one of the solenoids, shifting it so the motor would run freely and they would see the return flow through the flow meter. As they were increasing the flow, the pump pressure started climbing beyond the 72-psi pressure drop expected for 14 gpm, and once they had all 10-gpm pump flow going back to the tank, the pump pressure was 600 psi. They rightfully determined that there must be a restriction somewhere or that the motor required a much higher-pressure drop than expected. To check this, they disconnected the motor and looped one of the hoses to connect the A and B ports on the ISO-3 sub-plate. They still had the high-pressure drop. They tried another new valve off the shelf, and it didn’t help. They inspected the sub-plate to find all the drilled holes and fittings were drilled properly. They thought that may-

When outriggers fail to retract, not only can pressure spikes cause the problem, but temperature changes can also affect the pressure in trapped fluids. For every 10°F change in temperature, common hydraulic oil will expand approximately 0.5%. If it is trapped in a confined area like outriggers that are bottomed out, its pressure will increase approximately 1,000 psi per 10°F of temperature change. The ambient temperature (air temperature) changed 50°, increasing the trapped pressure an additional 4,000 to 5,000 psi. The mechanic brought four bags of ice from their ice-making machine, layed them on the outrigger cylinder tubes, and in no time, the oil cooled down, lowering the trapped pressure to a point where the system pressure would now open the locking pilot to open checks.


be a QD was malfunctioning, so they replaced all the QDs and at the same time checked all the ½" hoses for obstructions. None were found. They did notice that one end of all the ½" hoses had a male SAE O-ring thread, and the other end used a 37° tube union with an O-ring to connect to the QD. The hose had a female 37° that the other end of the union fit into. The 37° tube threads are identical to the SAE O-ring, and a lot of shops (including ours) just add the #908 O-ring to convert it to a SAE #8 connection. They had a hose with female 37° ends on both ends, so they looped the pressure and tank manifold connections together, and the pressure was less than 20 psi. They eliminated the pump outlet to the manifold plumbing.

GARY GOTTING moved from Sussex, England, to the United States 15 years ago and has more than 30 years of experience in the fluid power industry and electro-hydraulics international arena, holding roles of increasing responsibility in various design, manufacturing, sales, and marketing positions. In 2013, Mr. Gotting moved to Sun Hydraulics Corp. in Sarasota, Fla. to take up a senior position in the marketing area promoting all aspects of the company’s cartridge valves, controllers, and integrated package products.

DAVE STAGG graduated from the University of New Mexico with a degree in economics. He started working in the fluid power industry in 1976 purely by accident. Mr. Stagg has spent the majority of his career involved in mobile hydraulic sales through distribution, and he currently works for HAWE Hydraulics as the western regional sales manager.

JEFF FINCH is senior vice president and general manager for Eaton Hydraulics Products and Markets. He leads a high-performance global team of product management, engineering, business development, program management, and other professionals responsible for profitably growing the hydraulics business. Mr. Finch is an active participant in the Association for Hose and Accessories Distribution and the National Fluid Power Association.

RICK SPORRER, CFPHS, is vice president of sales (Americas) for Danfoss Power Solutions. He is responsible for the sales organization in North and South America, including account management, order management, systems and application engineering, and warranty administration. Mr. Sporrer has held positions in design engineering, applications engineering, account management, warranty administration, quality, and continuous improvement during his 24 years with the company.

THE QUESTIONS What areas of growth or opportunity do you see developing in 2015 for the domestic/international mobile market? GOTTING: Following and supporting OEM customers that expand to other countries, and offering new products that allow opening new markets in different global arenas. STAGG: In 2015, there are opportunities in agricultural equipment.

There is an increasing demand for more mechanized fruit harvesting equipment due to the rising labor rates and lack of workers available to do the work. FINCH: Many are still struggling with how to view the markets since

the great recession. We’ve seen more volatility and more of a mixed bag globally. However, amidst all that volatility, the macro trends favor our industry—from rising food production needs, to efficiency increases and carbon footprint reductions, and increased needs for intelligent machines to make job sites more productive and safe. Coming down from the macro to the street level, that same volatility and uncertainty is driving our customers to look for innovative solutions and move beyond the status quo. One direction the market has followed is the development of more intelligent systems, and that is certainly the case for Eaton products, as well. The concept of electro-hydraulics, instead of purely hydraulic or mechanical hydraulic solutions, is developing across the industry. For example, advanced mobile valves with built-in electronics allow for onboard pressure sensing and internal position sensing. These electronic technologies have built-in software for pre-loaded functions, which are built into valves to control specific machine functions. Another opportunity lies in complete hydraulic system solutions, which are becoming more popular with original equipment manufacturers (OEMs) who today want an entire system that works seamlessly together. SPORRER: Most economists are expecting the U.S. economy to expand about 3% in 2015. If accurate, it would be the first year of 3% growth since 2005. Economic growth and the production and consumption of goods are a positive indicator for the material handling equipment market. The continued steady increase in single-family housing starts, coupled with the recent lowering of mortgage interest rates, are positive indicators for the construction equipment business in North America. In 2014, the U.S. government announced an initiative to increase investment in ports, roads, bridges, broadband networks, and drinking water and sewer systems by facilitating partnerships between federal, state, and local governments and private sector investors. More recently, the government announced a new set of infrastructure tax proposals that will improve the ability to combine public and private investment so that local and state governments can more easily work with the private sector to advance the public interest. This effort is a positive indicator for the construction, road building, and material handling markets. Mobile equipment manufacturers will continue to invest in technologies that provide differentiation and increase the value to the end customer. One such solution is telematics, and we anticipate

that smaller OEMs will continue to follow the lead of larger OEMs in telematics-enabled machinery this year. Internationally, safety regulations in Europe have driven and will continue to drive development of solutions to help customers meet the safety requirements.

What challenges (in terms of technology, regulations, efficiency, productivity, etc.) will the mobile market face in the upcoming year, and what does the industry need to do to handle these challenges? GOTTING: Simplified but smart products; an increase in bundled technology; simpler-to-apply integrated solutions that are more compact, lighter, and easier to integrate; dock-to-stock requirements from customers to provide better inventory control; and lead times that are less than four weeks. STAGG: The Tier 4 engine regulations and talk of a potential Tier 5

requirement are a large source of concern for mobile OEMs. These regulations require extensive machine redesign and add significant cost to the machines. I am not sure that the industry can impact these new regulations. FINCH: Regulations have had a tremendous impact on the industry for the past decade. Tier 4 requirements drove a tremendous amount of cost, but also drove (and is still driving) innovation. From a mobile machine standpoint, it’s very interesting to participate in the evolution of the technology. We are making a rapid leap toward more advanced machines, and that’s just the start. From purely mechanical, to a mix of central and distributed intelligence, to fully intelligent components that are plug and play, the most exciting aspect as we move up that technology curve is that we are closing in on fluid power technologies and intelligence that is much easier for the designer to apply, invisible to the operators, and easier for the technicians who work on them. With connected machinery, productivity is beginning to take off. Another challenge of interest is the productivity of our customers. When discussing productivity, our industry tends to focus on the productivity of the machine end user, but we must also be aware of the productivity of OEMs who are designing, building, and servicing machines. Easier-to-use software, built-in function blocks, on-board sensing and diagnostics, and self-calibrating plug-and-play components for easy replacement are all examples that are helping make their selection, design, prototyping, and production processes much faster and more efficient. Safety requirements have also risen to the forefront, as Safety Integrity Level (SIL) mandates require components and system design to have certain capabilities to provide adequate machine safeguards. Customers are now looking to OEMs and component suppliers to help meet SIL capabilities. Finally, across many types of equipment, customers are looking for increased hose performance. Pressures are going higher (500-bar pressure is not uncommon for closed-loop transmissions), and reliable hoses can be key to equipment uptime. To extend hose life and meet these pressure challenges, we’re working to improve abrasion resistance and provide better flexibility for ease of installation. • March/April 2015 •


MOBILE MARKET SPORRER: For years, mobile equipment man-

ufacturers have been devoting the majority of their engineering resources to Tier 4 engine integration. Engineering organizations are now being challenged to bring on a new wave of innovation and offset cost increases associated with Tier 4. To accomplish this more quickly

and efficiently, equipment manufacturers and suppliers must identify ways to work together. Another challenge that exists in the industry is the overall experience level of engineering groups. Many equipment manufacturers do not have the engineering capacity for specialization in hydraulics and electronic controls.

LifeSense® stands guard.

Finally, attracting and retaining experienced manufacturing support personnel is stretching our supply base resources. Improvements in manufacturing productivity and the implementation of new manufacturing technologies are typically paced by the availability of supplier resources and/ or our own experienced team members. Improving our ability to share best practices globally will help us leverage the experience of our teams.

Eaton LifeSense Hydraulic Hose Condition Monitoring System

How can the mobile market ensure the longevity of its workforce and attract young people into the field?

When hose failure is not an option,

When your operations are critical, hydraulic hose failure can be catastrophic. Beyond idled assets, a failed hydraulic hose can damage equipment, harm the environment and pose personal safety issues. That’s why Eaton’s LifeSense technology continually monitors the condition of your hoses and issues an alert when a hose is near the end of its useful life.

GOTTING: More colleges offering mechatron-

ics courses, re-training, and the introduction of smart products that combine hydraulics with electronic controllers that are interesting, captivating, and familiar to many young people who use high-tech and visual indicators in their daily lives with ease. STAGG: The mobile market can attract young

people by supporting existing schools that offer degrees in fluid power, visit and recruit from these schools, and offer apprenticeship programs to students. Keeping pay rates in line with other professions in competitive markets will also contribute to longevity in the workforce.

FINCH: The convergence of electronics and hydraulics is continually reinventing the industry, leveraging new innovations to change the dynamics of fluid power technology— which is, in turn, creating a more innovative and thus more attractive field. Promoting this evolving industry will help build a better perception of fluid power—from leaky and noisy machines of old to the mechatronics and complete machine design we work on today. Another step is catching students in K-12 to promote our evolving field and to get young people excited before they reach the university level. • March/April 2015 •

THE QUESTIONS sector. In the U.S., we need to find ways to encourage younger individuals preparing to enter the workforce to strive for longer-term careers in the field. The mobile market can improve in this area by teaming with and supporting educational partners. By working with schools and universities, we can point out the types of career potential and technology available in the industry. Providing support for organizations like Project Lead the Way (https://www.pltw. org) and First Lego League (http://www. are excellent ways that our industry can help attract the next generation of talent to our industry.

How can the mobile market remain competitive in 2015 and in the future? GOTTING: Design smarter products that interface directly with vehicle infrastructures, wireless configuration, access via smart devices to allow in-field set-up, configuration, test, and diagnostics. Look to add prognostics for preventive maintenance, and start to fall in line with expectations set by the automotive industry for interconnectivity. STAGG: The mobile market can remain com-

petitive by continuing to invest in the latest manufacturing technology, thus maintaining a competitive price in the marketplace. These technologies will also allow us to offer high-quality products that are superior to those coming out of China. development around complete machine solutions is one of the best ways to take advantage of the benefits and capabilities of fluid power. Mobile equipment users across industries are looking for larger, faster, more powerful machines across the board, with increasing pressure and flow rates, as well as power density. As engine efficiency grows, hydraulics can help maximize machine power. At the same time, customers are looking for ease of maintenance to help keep these big investments up and running. Integrating electronics with traditional hydraulic solutions— from valves to hoses and more—provides much needed monitoring and reporting. When customers can easily determine when preventive maintenance is needed before a machine breaks down, they are getting the most out of their machines. These and other creative and intelligent ways to manage power can help the industry thrive. By focusing on the needs of everyone in the value chain, the market can continue to innovate and grow.

SPORRER: Companies in the mobile market segment can compete and endure by understanding and adapting to the interests and needs of the different generations that exist in our business. I have observed a number of companies adjusting their work environments so that communication tools and learning op-

portunities are targeted for each generation. In today’s global market, regulatory challenges and easy access to information require even small companies to think globally. Companies can stay viable in their competitive climate with commitment to innovative technologies and responsiveness to customer needs.
