INTERNATIONAL FLUID POWER SOCIETY

What would be your answer if you were asked: “Do you want to grow?” For most, if not all of us, I’ll bet the answer would be a resounding “Yes!” Yet many times, we choose to stay in our comfort zone because of fear. Most of us have been taught to live in our comfort zone, but if we are going to grow, we need to make some changes and stretch ourselves beyond where we are today. My son, who recently turned 16, stepped out of his comfort zone as he started looking for his first job. He struggled through the first interview and in his own words, “The interviewer really didn’t pay attention to my answers to his questions.” I reassured him that, if this was the case, he probably wouldn’t want to work there anyway. When submitting his application at the second company, he was told it would be turned in, but he probably wouldn’t get the job anyway. Shocking, right! Again, I counseled him that this was not a good place for him to work either. Finally, after applying at a local employee-owned grocery store, he landed an interview. A few days prior to the interview, I asked him two very important questions, “Why do you want to work for this company?” and “What do you know about this company?” I got a typical 16-year-old response, “I don’t know.” So I coached him on these two questions and asked him to do a little research. As he began the interview, he was nervous. But when the interviewer asked him these exact questions, the nervousness melted away and he gave an answer I’m sure the interviewer had never before heard from a shy, 16-year-old young man. After getting rejected by the first two companies, my son stretched himself a little bit and it made all the difference. He got a call the next day with the offer to start work at the grocery store. Why? Because he stepped out of his comfort zone, did his homework, and stood out in the crowd. Many people finish high school or college and look forward to never having to crack open another book or take another class. When I graduated from college, the euphoria set in that I would no longer have to enroll in classes or take tests ever again. Reality has proven me wrong and I’m glad it did. I never would have grown as much and gone as far without having stepped out of my comfort zone. Growth is essential if you want to get from where you are today to the place you want to be tomorrow. Stepping outside our comfort zone is never easy, but the rewards are countless. What you do over the next 30, 60, or 90 days could make a difference in your next job, your next promotion, or your next sale. So what’s it going to be?

Control and Diagnostic of Electro-Hydraulic Machines PRESENTED BY: ANDREA VACCA, PROJECT PI, PRESENTER AND PROFESSOR OF FLUID POWER SYSTEMS, AND ALBERTO ASCOLI, GRADUATE STUDENT INSTITUTION: PURDUE UNIVERSITY

PURPOSE Electro-hydraulics has enabled advanced control techniques to develop throughout the field of mobile hydraulic machine manufacturing. The goal of the investigation is to test how well can an electro-hydraulic machine, in this instance, the 16MO2, can adapt to a large variety of conditions and perform additional parameters. While analyzing the general applicability of mobile hydraulic machines, the researchers also sought to examine how the control parameters are related to the machine’s dependency.

PROGRESS Choosing to stay away from extremely complex operations to test the control dexterity under specific parameters, the research team focused on the independent metering valve block of the 16MO2 for their diagnostic review. The unloading valve, meter-in valve, and meter-out valve provided a closer look at the correlation between controller cost functions and faults analyzing the volumetric efficiency, meter-in friction, cylinder friction, and unloading valve friction. Next came the investigation of experimental validation to test the reproduction of faults (cylinder faults, pump faults, meter-in/meter-out valve faults, etc.) in the outerboom cylinder. In doing so, the researchers modified the cylinder fault with an adjustment to reduce leakage. This simulated the cycles of accelerated pump usage, translated as valve opening evolution, because a

pump can have different aging cycles based on a number of conditions. The tests allowed the researchers to develop a prognostic algorithm capable of estimating the remaining useful life (RUL) of the hydraulic components.

NEXT STEPS The analysis of the life of the pump did follow the research team’s algorithm, affording them the ability to correctly simulate the RUL and predict the pump’s life span under a variety of conditions, from generalized hazard functions to specialized hazard functions. The isolated fault analysis, specifically at the pump and valve faults, has provided enough information through simulation and data acquisition that the researchers are ready to explore how sensitive the control algorithm is to valve performance. After concluding the 16MO2 project, the team gathered the diagnostic algorithm with datadriven methods, the simplified open-center system, and control strategy for independent metering to create a new goal. Going forward, the research team recognizes that the critical component of mobile hydraulic machines is the meter-out valve. As it is where the algorithm is the most delicate or sensitive in the experiment, their new efforts will now focus on the experimental validation of the meter-out valve and how it affects component life distribution and concurrent component degradation.

ISO STANDARDS AWARENESS FOR FLUID POWER PROFESSIONALS

By Denise Husenica, NFPA International Standards Development Manager, Secretary, ISO/TC 131 and Administrator, U.S. Technical Advisory Groups

The International Standards Organization (ISO) began in 1946 when delegates from 25 countries met in London to create a new international organization “to facilitate the international coordination and unification of industrial standards.” Since then, ISO has published over 22,230 International Standards covering almost all aspects of technology and manufacturing. ISO members hail from 160 countries and consist of 783 technical committees, subcommittees, and working groups to take care of standards development.

Why standards matter in fluid power?

2. Design standards establish dimensions, tolerances, or other physical characteristics of products. They ensure that fluid power products meet dimensional criteria that enable interfacing and interchangeability. 3. Performance standards provide a voluntary method of rating products. Pressure rating, particle counting methods used in contamination analysis, and methods of testing for strength and volume are typical performance standards.

Why get involved in standards development?

ISO Standards, technical specifications, and technical reports One of the strengths of ISO standards is that they are created by play a key role in fluid power technology. Designing, assembling the people who need them. In the United States, 145 fluid power and maintaining a hydraulic or pneumatic system typically involves industry experts drive all aspects of the standards development putting together a variety of components, often from a variety of process, from deciding whether a new standard is needed to defining suppliers. Without standards for dimensional interchangeability, the technical content.

ISO/TC 131 Subcommittees

Standards benefit users because they: • simplify the use of fluid power; • help educate users on how to correctly size and apply products; • determine product performance and how it is measured, allowing comparison; • communicate needs in a commonly understood language; and • are written with input from users.

How modern hydraulics can contribute to greater efficiency and precision in agriculture

PRECISION FARMING By Dipl.-Ing. Matthias Müter, Dipl.-Ing. Ralf Leinenbach, and Dr.-Ing. Uwe Seel, Hydac

the turn of the year 2017-18, the world’s population was about 7.28 billion people.1 The United Nations expects this number to rise to 9.5 billion by 2050.2 The agricultural area per person dropped from 0.74 acres in 1961 to 0.49 acres in 2012.3 While mechanization, breeding, and area expansion have so far been able to produce higher harvest yields, and thus maintain growth, a different solution will be needed in the future. The amount of land available for agricultural use is, after all, not unlimited, and the current increases come at the cost of valuable untouched woodland resources. Agricultural land is also being used to grow energy crops to meet the increasing demand for energy. Agriculture, just like industry, sees the Industry 4.0 (Fourth Industrial Revolution) as the next development step that will increase the efficiency of production, with more intelligent machine control providing greater yields and reduced loss in harvest, transport, and storage. Another goal is to reduce the consumption of fertilizers and pesticides by collecting and analyzing large volumes of data (“big data”). In summary, precision farming means: greater knowledge, more intelligent control, and more efficient performance. This is precisely where intelligent mechatronic systems can help.

AWARE OF THE MACHINES DOINGS: NOW AND HOW

High-precision hydraulic controls make it possible to increase working width and speed. Intelligent systems (e.g., GPS steering, headland management) reduce the drivers’ workload, allowing them to work more effectively and with less stress, while giving them time to plan subsequent tasks. Components like the modular HY-STEER system (Figure 1) for electro-hydraulic superimposed steering systems, use GPS data or sensors (row / lane recognition) to support autonomous steering of the machine, with safety playing a crucial role. Manual steering will still be given priority so that the driver can intervene at any time. Depending on the particular safety requirements, partially or fully redundant systems can be used with duplicate sensor, control, and valve technology, with appropriate software and controllers.

The latest developments in agricultural machinery focus on increasing output per area to reduce working time and costs. This can be achieved by increasing the working width or improving the speed. However, these two factors combined with vibrations and bumps in the ground surface made it difficult for the rod system to be kept at a constant height above the crop. Deviations in height impair the efficiency of the plant protection product. To reduce the driver’s workload without compromising height consistency, components can be used to establish active rod system control. Ultrasound sensors monitor the distance between the rod system and the crop, and the controller actuates proportional valves to correct any deviations (Figure 2). The intelligence of this system is located mainly in the TTC controller, as the system needs to regulate the height with limited vibrations despite the intense motion forces involved. The proportional poppet valve series PWSM06020W, developed especially for this application, has an adjusted characteristic curve that enables sensitive turning and rapid compensation movements.

DRIVERS

ASSISTANCE To increase output per area, the working widths of tillage equipment and sowers have become increasingly larger in recent decades. The tasks performed remain the same. When sowing, the distribution, the separation, and the exact filling of the seeds are monitored and regulated. In both soil working and sowing, the working depth must be set and continuously readjusted. With working widths of 75 feet, the ground conditions can vary so much that the working depth needs to be set in individual segments distributed across the working width. This means that hydraulic oil has to be supplied to up to 40 cylinders that are working with a variety of pressures and cylinder strokes. Using central control blocks usually results in thick hydraulic hose bundles supplying the individual cylinders.

FLEXIBLE DEPTH, MINIMIZED HOSING Fig.1c

Distance Measurement

The smart cylinder (Figure 2), allows the hosing to be minimized as the cylinders are connected to a continuous pressure and tank line, much like an electronic bus system. The valves, the controller, and the pressure and position sensors used to control the cylinders

are integrated in each cylinder and are connected to a CAN bus. The optimal sowing depth can now be calculated on the basis of offline geo-reference data or online sensors. The individual sowing units are controlled via CAN bus signals, so that various sowing depths can be set to match local soil conditions (Figure 6). This results in better plant growth and increased yield. Thanks to the functionality of the smart cylinders, they are also recommended for other applications in agricultural engineering. Precision farming entails stricter demands with regard to function, precision, and processing time. This

results in a significant increase in the complexity of the machines as well as the corresponding mechatronic systems. The electronic part of these systems needs to be able to process more and more information in increasingly complex calculation algorithms. Accordingly, more and more data and data flows are transmitted between various controllers within the machine, between human and machine, or externally to other machines or communication networks. HYDAC offers a telematics module for this purpose, TT Connect Wave. Sensors are responsible for detecting what the machine is

currently doing and how. Whenever more information is required to enable particular functions, more sensors are needed. It is not only the number of sensors that must be increased, but also the number of measured variables. Thankfully, an extensive range of sensors has been developed to meet these needs (Figure 4). For applications in agricultural machines, these are mainly sensors for pressure, distance, position, angle, inclination, fluid level, temperature, and speed. To accommodate this large number of different sensors, some with different output signals, electronic controllers need

to have numerous input channels with highly flexible signal adjustment. The calculation algorithms, which are sometimes complex and often need to be run in real time, require a highly powerful computer core. The controller requires access to a large number of sufficiently powered switching and proportional outputs to control the hydraulic actuators. On the machine side, the functional units still largely communicate via the classic CAN bus. Agricultural machines in particular mainly rely on ISOBUS communication, which has become standard. These requirements can be met by controllers from the HY-TTC 500 family. A high-power 32 bit processor core forms the hub of these controls that meets the needs of the sensor system and the hydraulics with almost 100 inputs and outputs. CAN and ISOBUS interfaces enable internal and external machine communication. Modules of the HY-TTC 30 family can be added for decentralized architectures or simple I/O extensions.

To put together a complex system made up of hydraulics, sensors, controllers, and control algorithms, considering the subsystems individually is not enough. This particularly applies to highly dynamic systems such as the suspension in agricultural vehicles or position control for attachments under the influence of oscillation caused by bumps in the ground and steering movements. To allow the interactions of sensors, controllers, and hydraulics to be optimized early on, simulation tools such as AMESim, MATLAB,

or RecurDyn are recommended as needed, and even combine them for co-simulations. This makes it possible to discuss the interactions of the components with the vehicle manufacturer early on and to optimize them with regard to the mechanical conditions. Exchanging mathematical simulation models with the manufacturer simplifies the entire development process. In the further development stages, the vehicle developer faces the task of combining the domains of hydraulics, sensors, controllers, and displays as well as possible, then testing them. For this task, development-support software program like “MATCH” is well-suited. MATCH is a modular development environment that supports the designer in system development, software development, testing, initial operation, and simulation, in addition to documenting results.

DEVELOPING ELECTROHYDROSTATIC ACTUATION TO IMPROVE RING ROLLING PRODUCTION By Dr. Erkhard Siemer, General Manager for Design Hydraulics and Electrical Engineering, SMS Group GmbH, and Achim Helbig, Dr.-Ing, Innovations Projects Manager, Moog Industrial Group

Moog’s new Electrohydrostatic Actuation System was developed jointly with SMS Group GmbH. In this interview, SMS’ Erkhard Siemer explains how the project evolved, and how the system has improved the group’s production performance.

Last year, Moog launched its new Electrohydrostatic Actuation System (EAS). Moog developed the EAS in cooperation with the SMS Group, the company is a leader in manufacturing ring rolling mills. Could you tell us some of the background to this project please? A: Prior to the development of the EAS, we operated our manufacturing machinery using a central hydraulic system, which featured a large oil tank and complex piping. This set up required significant and additional internal infrastructure – such as room space that housed our central hydraulics systems – near the machine operating area. This proved very costly for us, both financially and timewise.

Can you say a little more about why this particular arrangement proved to be so expensive? A: Our previous actuation system required central hydraulics storage facilities that proved to be inefficient in terms of energy, especially

NOVEMBER/DECEMBER 2018

during part-load operation. For instance, the accumulator assisted hydraulic system made use of pumps that were constantly working against high pressure. High-resolution, dynamic servo hydraulics operated the rolling axes, and the power flow was controlled or throttled via the servo valve. As a result, some systemic throttling losses occurred, and these had a detrimental effect on the overall efficiency of the machine. Consequently, fast, rapid movements characterized our machine cycle, but these occurred without force, which resulted in slow high-resolution movements and high force levels with partially changing directions of force.

What are your expectations of the new system? Do you wish to maintain any of the previous system’s attributes? A: The previous system was robust, overload-proof, and characterized by high availability. We wanted to preserve these qualities. On the other hand, we wanted to

eliminate the complex central hydraulics and its various connected features. Our aim was to arrive at a simplified and shortened installation process, and faster commissioning of the rolling machines. The removal of the central hydraulics resulted in significantly reduced noise levels and an overall improvement in safety. Furthermore, the machine operated much more productively and with better levels of energy efficiency.

In short, it sounds like you were looking to achieve higher productivity, lower power consumption and, at the same time, simplified and cheaper installation? How did the EAS help you to achieve this? A: The Electrohydrostatic Actuation System combines two worlds. On the one hand it offers the energy saving advantages of an electromechanical actuation system based on the principle of “power on demand,” and on the other, it has the advantages offered by hydraulics in terms

WWW.FLUIDPOWERJOURNAL.COM • WWW.IFPS.ORG

of robust power transmission, low cost, high performance, and availability. Basically, the EAS design concept combines electrical and hydraulic components in one system. We were very interested in this electrohydrostatic solution because we needed to apply very high forces (> 1 MN) in the production of ring rolling machines. In addition, extreme shock loads can occur during this process, which, in essence, is the domain of hydraulic actuation. The EAS can implement these forces during its hydrostatic transmission. Together, we considered our requirements, embarked on the project and developed a new machine type.

Can you give us a brief description of how this system works? A: We positioned the Electrohydrostatic Pump Unit (EPU) directly on the machine manifold in order to save space. The manifold contains all of the required overload and logic functions. We mounted it directly on the hydraulic cylinder, and the servomotor, pump, manifold, and hydraulic cylinder form a functional unit. By doing this, we were able to reduce all piping on the cylinder to a minimum. We integrated the electrohydrostatic functional units directly with the machine axes. Since the pump is able to vary delivery volume, high-speed fast movements, and low-speed high-force working movements proved easy to implement. All servo drives are electrically connected via a common DC bus, powered by a regenerative power supply unit (PSU).

Can you tell us something more about energy efficiency? How were you able to save energy? A: The EAS offers significant energy saving possibilities. Compared to conventional ring rolling machines, the modified axes on this machine operate with up to 40% less energy consumption. The connected load is significantly reduced, and in addition, the new machine design eliminates any need for piping. The construction of the machine is so much easier. Since we were able to reduce the oil requirement from roughly 2,000 to around 200 liters, we eliminated the normal footprint generated by a large hydraulic unit. Because hardly any hydraulic oil is required, this significantly reduces the need for consumables and related equipment. In addition, the system is significantly quieter on the whole. By eliminating the flushing time of the central hydraulics and the pipelines, we were able to save between 1 and 2 days commissioning time.

How did the change in axes save energy? A: EPU/EAS technology is a power on-demand technology. You have to provide on the electric power input, the power you need on the cylinder rod only. This is the main difference compared to a classic HPU + valve driven hydraulic system and leads to energy savings. On the other hand, the technology allows energy recovery. This is an additional point to increase the energy savings further.

3 Billion

Solutions ...and expanding

Are you doing less work? Or are you doing the same amount of work more efficiently? A: We are doing the same amount of work much more efficiently without principal losses.

What is the response time of the servomotors and how does it compare to the response of the servo valves? A: To give an example: The 19cm³ EPU can provide a maximal flow of 85l/min. A step response from 0 to 85 l/min you can realize within 35ms. The -90° frequency @ 5% amplitude on such unit is 90Hz. Such a dynamic performance is comparable to proportional valves.

If you are using the same cylinders, how is that you need less hydraulic fluid? A: In EAS systems, you have to fill the hydrostatic gearbox with oil only. That implies the cylinder, hoses, pipes, and pump are filled with oil. Additionally, a certain oil volume to compensate cylinder area difference is needed. That's it. A big open tank like on classic hydraulic systems isn´t needed any longer because the losses are much smaller, therefore the oil heating up is smaller too. On the ring rolling machine, we were able to reduce the overall oil volume of the machine from 2,000 to 200 liters. This leads to a much more simplified infrastructure around the machine.

The global market leader with failure rates less than 1 PPM, SFC KOENIG is recognized for excellence in sealing and flow control. The original inventor of the pre-assembled metal-to-metal seal solution, we offer: • a variety of sizes, materials and pressures • engineering support • faster installation & fewer errors • proven effectiveness in a variety of precision high-performance applications.

Any final comments about the project experience? A: We definitely drew upon Moog’s expertise with hydraulic design, pump technology and electric drive technology. In fact, the collaborative process with Moog lasted for over eight months, beginning with the dimensioning of the axes and continuing through the machine integration process and assessments of functional safety. Then we undertook the commissioning stage and the final analyses of machine performance.

FIGURE IT OUT

NEW PROBLEM

Large Punch Press Cylinder Stutters On Downward Extension An OEM had a hydraulic distributor design an HPU for a punch press he wanted modified to punch large stainless-steel discs that were then sent to a forming press. The final product was the end caps for cylindrical air compressor tanks. After the used press was mechanically upgraded they installed the new hydraulic power unit, and during commissioning, they experienced a problem with the ram stuttering on the downward extension, but working just fine on retraction. They could get the desired tonnage at the bottom of the stroke. They also told me the reason

Solution to Previous Problem

INJECTION MOLDING MACHINE NOT UP TO SPEED

for the meter-in flow control on the rod was to slow the cylinders retraction rate due to the high flow going back to tank and that there was dwell time moving the plate stock into its next position. Another problem was the spool center position needed to be changed so the press could be stopped without the ram wanting to fall to the lower extended position.

A proportional throttle valve will pass a relatively constant flow if the differential pressure across the valve is constant. If you increase the differential pressure, the valve will pass additional flow. The load sense compensator on the pump was set too low, causing the delta “P” pressure to force additional flow across the valve to be low. Adjusting the load sense compensator higher solved the problem. VISIT FLUIDPOWERJOURNAL.COM TO VIEW PREVIOUS PROBLEMS.

COMPRESSED AIR SYSTEMS:

ARE YOU DRAINING AWAY YOUR PROFITS

By Ron Marshall

Airless drains save compressed air and reduce operating costs

Source: Compressed Air Challenge

Air compressors create water, there is no way around it, the ambient air is squeezed, like wringing a sponge, and cooled, creating a constant flow of condensed water at the discharge of the compressor, as well as at various points down the line, like at air dryers and filters. How well you remove this water affects not only the quality of the compressed air, but also your operating costs. Consider a 50 hp air compressor running fully loaded on a hot, humid summer day, just after a rainstorm, with inlet air at 80°F (26°C) and relative humidity of 70%. Under these conditions, the air compressor will produce about 34 gallons of water in a 24-hour period. Any timer style drain would have to be set to drain frequently enough to remove all the water, or the excess would flow into the air dryer, which is not designed to process free water. On the other hand, during cooler, dryer conditions, such as 70°F (21°C) ambient and 30% relative humidity, the amount of water produced would be only about 12 gallons per 24 hours, therefore the previously set timer would drain excessive compressed air to remove water that is not there. Similarly, at the air dryer drain, the amount of water being expelled under the hot conditions would be about 9 gallons per 24 hours. But under cool conditions, about 4 gallons would be condensed from the air stream. Of course, these calculations assume that the compressor is fully loaded, if it is running at partial load, the timer drain wastes even more compressed air. Best practice for compressed air condensate drainage is to have a drain style that works on demand. If the amount of water is high, the drain will operate more; if less, then the drain automatically cuts back. Drains that use level operated internals are the most suitable for this

type of operation, even better if the drain uses no compressed air at all, as are the characteristics of some of the zero-loss styles. Some tips on selecting the best drains for your system: • Place drains anywhere moisture might collect, like low spots in piping, especially after points where the compressed air undergoes a temperature change. • For gravity-fed drains, ensure the piping is routed to provide a good flow path for water (water doesn’t flow uphill) and don’t skimp on pipe size to prevent air lock. • Always place a strainer with a clean-out port (with ball valve) so that pipe scale and lubricant debris can be drained out of the water stream without clogging the drain. • Purchase drains that have an easy test method, and train your operators to regularly confirm the drain is operating. • Purchase drains that have a port where water levels can be seen so proper operation can be confirmed. • If air lock is an issue, then a small amount of air may need to be drained to promote flow. • For lubricated compressors, the condensate will contain oil. Be sure to dispose of it responsibly.

IMTS 2018

IN CHICAGO’S MCCORMICK PLACE

The International Manufacturing Technology Show (IMTS) inundated the McCormick Place convention center in downtown Chicago on September 10-15, 2018, and raised the bar not only for the IMTS conferences in the future, but for trade shows across North America. “IMTS 2018 set records because manufacturing technology has grown exponentially since [the] last show,” said Peter R. Edelman, Vice President – Exhibitions & Business Development at the Association for Manufacturing Technology. The records are indeed impressive with a reported 129,415 registered attendees interacting with 2,563 companies at 2,123 exhibition booths. To put that into perspective, the previous record for registrants was set in 1998 with 121,764 attendees. And 2016 saw the IMTS draw in 2,407 companies showcasing at 1,808 booths, holding the record until it was broken last September. If this year’s upsurge is any indication of the health of manufacturing technology across multiple industries, the future looks very bright indeed.

NOVEMBER/DECEMBER 2018

WWW.FLUIDPOWERJOURNAL.COM • WWW.IFPS.ORG

Across McCormick’s Place’s four interconnected buildings and open indoor arena, thousands of industry leaders, sales professionals, and technology innovators gathered for webinars, showcases, demonstrations, and press conferences. From robotics to data analysis to proto typing to cost justification, no topic was left unparsed and no gift tote left unfilled with brochures, business cards, and giveaways. “The rapid growth of digital technology, automation, and additive manufacturing are especially driving interest. The booming manufacturing economy means visitors have capital and are ready to invest,” said Edelman. The fluid power industry reflects Edelman’s assertion of an economic boom with an increase in IMTS participation across the scope of hydraulic and pneumatic applications. From Rheintacho to Schunk to Eurotech Elite, more than 65 fluid power innovators attended to represent the present and future of the industry. Given the remarkable growth of the event held at the largest convention center in North America, it would be no surprise if more fluid power professionals plan to join the IMTS conference in 2020.

Efficient Slip-In Check Valves Support Axial and 90 Degree Flow Paths It takes an enormous expense to support an inefficient check valve. A larger than necessary prime mover, heat exchanger capacity, and the ongoing expense (over the life of a machine) of pressurizing hydraulic fluid well beyond what is necessary to do useful work are a few of the realities of high pressure drop. Inserta® IGS (steel) Check Valves, Guided Disc, Slip-In Type, have pressure drop profiles lower than typical thread-in cartridge check valves, and may be considered in both axial and ninety degree flow path applications. Ninety degree flow path cavity examples are documented in the product literature, and may be found on the company website. No specialized cavity form tooling is required. The guided disc design (patent pending) affords improved longevity in applications prone to turbulence, as well as in higher cycling and higher flow applications.

Effective Leakage Testing with Bubble Tight Poppet Valves

Custom Industrial Control Handles, Pendants, Joysticks and Switches

Manufactured To Your Specific Requirements

BY JOHN WAYNE JENNINGS, VICE PRESIDENT OF SALES AND MARKETING, LEXAIR INC. There are many applications that require valves that do not allow leakage. For instance, there are often times when a casting, housing, or other part must be tested for structural integrity or its ability to hold a particular pressure without leaking. A bubble tight poppet valve is just the right device to be used in test circuits such as these.

The pressures required for leakage testing often exceed the normal 0.6 – 0.9 MPa (90 – 125 PSI) “shop air” range, and there is often a need for high-flow devices that can fill or exhaust the fixtures rapidly to reduce the overall time required to complete the testing. Some commercially available poppet valves possess the physical characteristics to meet all the required criteria, and they are high-flow devices by design. As an example, the application discussed below is for a test fixture that is checking for porosity in a casting using high-pressure air. A normally open poppet valve with a high ratio pilot (Lexair Inc. part number 325104) was chosen for the test due to the following: • The standard ability to handle high pressures • The standard high ratio pilot feature • The standard bubble tight construction • The standard high-flow capacity of a poppet valve The test requires the ability to withstand 2 MPa (300 PSI) (most valves by this manufacturer haves a standard rating of 3.5 MPa [500 PSI]). However, the available shop air pressure was only 0.4 MPa (60 PSI), so a pneumatic booster had to be used to create the required test pressure. To control costs, the booster is sized to create just enough high-pressure air to fill the volume of the casting being tested. There is no high-pressure air available for a pilot signal. Even if there was enough 2 MPa (300 PSI) air left over for use in piloting the poppet valve, finding a 3-way solenoid valve to control the 2 MPa (300 PSI) pilot signal would pose yet another challenge for the application. This meant finding a poppet valve with a pilot ratio that would allow the 60 PSI air supply to be used as the pilot source. With an 8:1 pilot ratio operating at 0.4 MPa (60 PSI), the chosen valve can close bubble tight on working pressures up to 3.3 MPa (480 PSI), easily meeting this criteria for the application. The poppet valve is basically piloted to the closed condition while 2 MPa (300 PSI) air is introduced to the casting from the booster. The pressure is held in the casting for a predetermined period of time, while a precision digital gauge (with outputs tied to a PLC) checks for pressure decay. The castings are also submerged in water so a visual test for bubbles is administered as well. The poppet valve must retain the air in the casting for the duration of the test without leakage. Once the testing is finalized and the casting integrity has been assured, the pilot signal is removed from the poppet valve and the normally open unit allows the high-pressure air to be quickly relieved to atmosphere from the test fixture.

THE

ROAD TO SAFETY CERTIFICATION BY CHARLES BUTCHER, JUSTIN SHELTON (HOERBIGER), AND EIKE STRATMANN (HOERBIGER)

NOVEMBER/DECEMBER 2018

HYDRAULIC LOCKING UNITS FOR PASSENGER RESTRAINT GAIN TÜV APPROVAL Ever had a bad dream involving a roller coaster? It’s reassuring to know that real-life amusement park rides are extremely safe, thanks in no small part to hydraulic passenger restraint systems. For many years, Hoerbiger has supplied ride manufacturers with hydraulic locking units (HLUs). The units are used to position the restraining device – a shoulder bar, waist bar or lap bar – and secure it in place. They have several advantages over purely mechanical systems, notably infinitely variable adjustment and a practically silent operation. More recently, the company has obtained safety certification for its HLUs from the respected German authority, TÜV SÜD. From idea to completion, the process has taken three years. With such an arduous journey to obtain certification, why decide to undergo this process, and why did it take so long? HOERBIGER sought TÜV certification to reassure its customers and ease their workload. The company has always designed and manufactured HLUs to the highest safety standards, and the new certification requirements have not changed that. For ride manufacturers, however, TÜV approval now means quicker and simpler specification, ordering, and commissioning. The products are certified to meet all the relevant standards – ISO 17842–01:2015, DIN EN 13814, prEN 13814:2016, and ASTM 2291–15 – and all the documentation is easily available. TÜV SÜD is also well respected in the amusement park industry.

Figure 1: Hydraulic locking units (HLUs) keep passengers safe by securing shoulder bars (seen here), waist bars, or lap bars. They offer a practically silent operation, infinite adjustability, and self-powered bar opening without the need for extra springs or cylinders. Figure 2: Function tests before delivery: Only 100% tested units leave the factory. Figure 3: TÜV certification for the hydraulic locking units gives customers the assurance they need – in a simple, maintenance-free package.

NOT A WALK IN THE (AMUSEMENT) PARK Scary rides test the physical limits of both passengers and machinery, so it should be no surprise that the requirements for TÜV certification in this field are extremely tough. In short, TÜV SÜD had to review the design basis of Hoerbiger’s HLUs, approve the company’s procedures for designing and testing the units, and conduct annual audits to make sure standards are maintained. The first step was to submit detailed design calculations, including finite element modeling (FEM), to show that the units can withstand any foreseen loads in both normal operation and emergencies. Next, TÜV SÜD looked at the actual materials of construction used. The company was requested to prove that it can document the source and quality of every batch of material, in terms of both the supplier’s records and its own incoming goods inspections. Material batches must also be related to production batches, and ultimately, to the unique serial number of each finished unit. WWW.IFPS.ORG • WWW.FLUIDPOWERJOURNAL.COM

Demonstrating the strength and other engineering properties of the materials to TÜV SÜD’s satisfaction required our company to develop new statistical test procedures. As a result, we are confident in the strength of the materials exceeds that required by the functional safety analysis. In production, the company had to show that the manufacturing process is carried out consistently, and that there is no possibility of contamination during assembly. The fact that Hoerbiger Micro Fluid GmbH already had ISO 9001 certification was an advantage here, so their precautions included: • strict packaging regulations for suppliers • comprehensive incoming goods inspections for oil-carrying parts using microscopy • additional cleaning of individual parts • maximum purity of compressed air, water, hydraulic oil and solvents • additional rinse cycles during manufacture Once assembly is complete, it is time to test the finished units. The company reinforced its

originally stringent test procedures by investing in new test benches and equipment. Every finished unit is inspected for dimensional tolerances, stroke length and force, leakage, and manual emergency actuation function. Finally, a burn-in test subjects each HLU to more than 1,050 cycles under a predefined load, with tight tolerances for the allowable stroke length. ENSURING MAXIMUM RELIABILITY DIN EN 13814 specifies an operating life of 35,000 hours, or in Hoerbiger terms, 5 million load cycles (the company additionally designs for a service life of 7 years). The combination of design calculations, material specifications, material testing, and finished-goods testing achieves a failure rate of less than one per billion operating hours (<10–9 /h). Each delivered unit meets the special requirements of prEN 13814:2016 for the safety NOVEMBER/DECEMBER 2018

At the heart of a hydraulic locking unit (HLU) is a bolted twin-pipe cylinder (1) that secures the restraining bar. The inner pipe guides the piston rod with the piston; the outer pipe carries oil from the rod side to the flange-mounted connection block on the cylinder base. The connection block (2) accommodates a diaphragm accumulator, a check valve, and two ports (3) used to fill and pressurize the unit at the factory. The accumulator (4) precharges the unit to a predefined pressure and accepts the oil displaced by the piston rod as it retracts. The energy stored in the accumulator during closing is also used to open the restraining bar at the end of the ride, making the HLU a self-contained system requiring no extra springs or cylinders. The poppet check valve (5) locks the piston rod in place during the ride by preventing backflow of oil. Two different configurations are available – locking in the extended and retracted rod positions, respectively – to suit different ride designs. The valve has a hardened seat for minimum leakage and maximum reliability. At the end of the ride, the check valve is actuated electromechanically to open the restraint bar. In an emergency, the check valve can also be opened manually. An optional second valve (6) increases passenger comfort by preventing the restraint bar from closing too tightly during the ride.

integrity of passenger restraint systems, and is rated to Performance Level e ready (PLe) under the prEN 13814:2016 standard. In summary, obtaining TÜV certification for these HLUs has required a great deal of work with very few changes to the physical product. For such safety-critical equipment, however, the company believes that the resulting peace of mind – and simplified business procedures for customers – has been well worth the effort.

NFPA Foundation Awards 10 Fluid Power Research Supplements

NFPA Members Invited to CCEFP Summit to Review Projects and Presentations BY ERIC LANKE, NFPA PRESIDENT/CEO

The NFPA Education and Technology Foundation is actively working to increase the number of university students educated in fluid power, and one of the ways it does that is by supporting academic researchers in fluid power. It helps to engage current and build the careers of future university faculty who are and will be in a position to teach fluid power to undergraduate engineers on their campuses. With this purpose in mind, the NFPA Foundation has just awarded ten $10,000 research supplements to ten faculty members working on fluid power research at six universities. The recipient universities, faculty members, and research projects are: • Georgia Institute of Technology: Prof. Tequila Harris – Science of Pattern Coating onto Heterogeneous Surfaces Using a Hybrid Tool • Milwaukee School of Engineering: Prof. Paul Michael – Polymer-Enhanced Fluid Effects on Mechanical Efficiency of Hydraulic Pumps (project in collaboration with UofCA-Merced) • Purdue University: Prof. Andrea Vacca – Individual Electro-Hydraulic Drives for Off-Road Vehicles

of California – Merced: Prof. Ashlie • University Martini – Polymer-Enhanced Fluid Effects on Mechanical Efficiency of Hydraulic Pumps (project in collaboration with MSOE) • University of Minnesota: Prof. Thomas Chase – High Efficiency Hydraulic Pump-Motors Employing Partial Stroke Piston Pressurization • University of Minnesota: Prof. Perry Li – Liquid Piston Gas Compressor/Expander for Compressed Air Energy Storage (CAES) and CO2 Sequestration • University of Minnesota: Prof. Kim Stelson – Understanding the Transient Nature of Wind Turbine Response to Create Advanced Controls to Improve the Efficiency of a Hydraulic Drivetrain Wind Turbine • University of Minnesota: Prof. Zongxuan Sun – Modeling and Optimization of Trajectory-Based HCCI Combustion • University of Minnesota: Prof. James Van de Ven – Efficient, Compact, and Smooth Variable Propulsion Motor • University of Wisconsin – Madison: Prof. Eric Severson – Seamless Electric to Hydraulic Conversion

These research projects independently represent more than $4.9 million in funding from a variety of organizations, including the U.S. Department of Energy, the National Science Foundation, and the Center for Compact and Efficient Fluid Power (CCEFP). They are an excellent sample of the growing body of fluid power research being funded by the federal government and other research organizations. The research supplements from the NFPA Foundation are intended to provide travel support so that each faculty member and one of their graduate students can attend and present their research at a series of designated industry conferences and research summits. This will help better connect these researchers with the fluid power industry and allow better cross-fertilization of ideas. Any funds not spent on travel will be used in general support of the research project itself. This year, the designated conferences will be the two summits of the CCEFP, scheduled for October 2018 and April 2019.

2018 IEOC & Foundation Golf Tournament Break Records A record-breaking 324 attendees from over 175 companies attended the 2018 Industry & Economic Outlook Conference (IEOC) at the Westin Chicago North Shore in August. This year’s conference attracted a number of first-time attendees and also included a number of fresh perspectives from new speakers to supplement conference favorites like Alan Beaulieu and Jim Meil. The high-level takeaway from most presentations is stagnant growth in 2019. Attendees can still review the conference presentations on the presentation library page of NFPAHub.com/events. Overall attendee feedback was positive as in previous years and illustrated the conference’s value in guiding company strategic planning and data analytics while providing opportunities to connect with professionals from across the fluid power supply chain. The NFPA Foundation Golf Tournament that officially opened the IEOC was also a record breaker with over 124 golfers from almost 70 companies braving the heat for a day of golf to benefit the NFPA Foundation. Over $10,000 was raised through sponsorships, and the 50/50 raffle hit a new high amount with $2,000 in tickets sold. That brought the money raised for the NFPA Education and Technology Foundation to $11,000 for this one-day event. Other special networking opportunities included a brand-new networking breakfast with a panel discussion, the well-attended Future Leaders lunch that featured a presentation on innovation from Andrew Johnson of ShelfAware, and the post-conference Future Leaders tour of the Dura-Bar foundry. Thank you to all our attendees for helping make this a successful event!

THE SOLUTION _ Strip and Assessment Initially, the damaged hydraulic cylinders were brought into the strip and assessment unit so that the engineers could take the cylinders apart and observe the point of failure. They observed that the cylinder’s piston rods had bent, causing cracking to the plating, as well as damage to seals, contamination of the hydraulic fluid, and entire hydraulic cylinder failure.

TELESCOPIC HANDLER DOUBLES LIFESPAN

WITH INNOVATIVE REPAIR DESIGN By Steven North, Design and Project Engineer, Apex Hydraulics, Ltd.

The construction industry is a gruelling environment for machinery. The heavy lifting, sparks, friction, and dust and debris means that all equipment has to be extremely hard wearing. Rented machinery tends to be put under further pressure, and clients want to make the most of their loaned equipment so it can regularly be worked on double or triple shifts. This machinery is also often worked right to the limit of its capacity and, in some cases, is over-stretched.

REGULAR BREAKDOWNS

A national plant hire company contacted Apex Hydraulics after experiencing an issue with its fleet of JCB 535-140 and JCB 540-170 telescopic handlers (telehandlers). Telehandlers are vehicles with a variety of uses across the construction industry. They enjoy the benefits of both a crane and a forklift truck. The vehicle can move around like a forklift, but rather than pallet arms that have limited movement, the long boom on a telehandler can be extended a great length from the body of the vehicle. The boom can be fitted with a number of different tool attachments, making it capable of lifting, moving, and carrying goods. The company was finding that the hydraulic mast cylinders of the telehandlers were all breaking down after about 1,000 hours of use—far too quickly to be considered an acceptable time for breakdown through normal machinery wear and tear. Therefore, replacing like-for-like would not be an efficient option. Unfortunately, the Original Equipment Manufacturer (OEM) had produced a standard cylinder that – while fit for purpose, was not capable of remaining intact under the extreme conditions required of it. The likelihood was that the vehicle was lifting and carrying loads when the boom was fully extended, putting excessive pressure on the neck gland of the cylinders. The cylinders needed to be repaired—but with a solution that could survive the strains of a busy construction site. The client approached our company to commission a design that would be more durable even under these extreme conditions. 46

NOVEMBER/DECEMBER 2018

_ Design Team The design team produced a new concept that would be far stronger and able to survive more extreme loads. Restricted by size limitations demanding that the finished cylinder fit into the same space as the original, the designers could not increase the size of the cylinder components. Instead the rod was made from a stronger steel, with increased resistance to bend, so that an occasional load that was in excess of its loading weight would not result in a permanently bowed cylinder rod. The steel was induction hardened with chrome plating so that pitting and galling would be reduced and nothing would scrape against the seal. The neck gland and piston were redesigned so that pressure or sideload from a temporary bend in the cylinder rod would not damage the rod coating and seals. The design was drawn up and shown to the clients to approve. _ Machine Shop and Fitting Department The parts were expertly manufactured by the engineers in the machine shop. Special seals were ordered in by the fitting department and the redesigned parts were fitted into the original cylinder. _ Inspection The parts were tested and inspected for safety and quality in-house by a dedicated inspection team. The real test, however, is out on the field as close observations are made of the longevity of the telehandlers with their newly repaired hydraulic cylinders.

RESULTING SAVINGS

The initial vehicles have already worked for over 2,000 hours and are still functioning well with no recorded machinery failures. This means that the lifespan of the telehandlers has already been increased by 100%. Thirty machines are already in service with the Apex-built repairs. With no known vehicle breakdowns due to hydraulic failure on these machines as yet, time will reveal the eventual lifespan increase. What is certain is that this repair has saved the company significant costs in replacement parts and down time.
