Whether it’s noise levels, efficiency standards, or strict limits on carbon emissions, the designers of off-highway machines must meet new requirements. In some cases, these strict regulations open the door to advances in technology, like electric solutions, as they operate quieter, with more control, and in some cases, emissions-free. While fluid power systems on these machines are still present, they’re no longer the only end-use power transformer present.

The goal here is to extend their usefulness of core products through software controls and integration. However, I believe it will be the multi-technology leaders that have the best long-term strategy to win the future. And as other companies become more targeted and niche, multi-technology businesses will also continue to drive consolidation in our industry. The different forces that are shaping our industry today are coming at a faster pace than ever before. However, this doesn’t mean that our marketplace is going to be unrecognizable in a mere 12 months.

PREPARING FOR SUCCESS
Like the Hydraulic Specialist certification, the first resource enhancement for Pneumatic Specialist certification is the creation of animated pneumatic circuits. In this offering, every circuit in the Pneumatic Specialist Study Manual is displayed in color. Each schematic is animated showing the path of fluid flow. (These aren’t narrated. They contain explicit notes or bullet points.) The schematics can be purchased as one complete package and used in conjunction with the Pneumatic Specialist Study Manual to enrich the learning experience by bringing the schematics to life.
The Pneumatic Specialist Certification Study Manual Update By Denis Poirier, Jr., CFPAI/AJPP, CFPS, CFPCC, CFPHS, CFPIHM, Vice President of Certification, The Eaton Corporation – Hydraulics Group If you received the January 2019 edition of the Fluid Power Journal, you might have read the article “Preparing for Success: The Hydraulic Specialist Certification Study Manual Update.” In that article, I explained how using a single source delivery method to prepare for certification, as an International Fluid Power Society Hydraulic Specialist, may not be the best method for everyone. Understanding that people respond differently, when using the same single source delivery method, the IFPS developed additional products to enhance the learning process for everyone. But did you know those same learning resources will be available for the IFPS Pneumatic Specialist Certification by early 2019?

The last option would be to attend an instructor-led review session. This environment appeals to the maximum number of senses and works well for the majority of all learners as it uses visual, textile and audio stimulation. Additionally, you work with an Accredited Instructor, can ask questions, work through practice exams, and interact with others who may share the same experiences and challenges that you do. This is typically the most effective method for knowledge transfer, and in many instances, this is also the most expensive option, as it can require both travel and time away from work.
If a self-paced program is more your style, then the Pneumatic Specialist Interactive Study Manual is for you. This fully interactive learning system uses audio narration in conjunction with animated schematics to walk you through the Pneumatic Specialist Study Manual one outcome at a time. Developed with the e-learner in mind, this program appeals to the multisensory learner and can be used in conjunction with a printed study manual to expand on the information provided in text. Interactive practice tests and quizzes are also included.

Kickstarting Seamless Electric to Hydraulic Conversion Presented by: James Van de Ven, Associate Professor, University of Minnesota, and Eric Severson, Research Assistant, University of Wisconsin-Madison Institutions: University of Minnesota and University of Wisconsin-Madison
»
PURPOSE Electric systems are taking over a lot of jobs that hydraulic systems have traditionally held. Despite this, the force and power density of hydraulics really make it the premier choice for energy solutions. James Van de Ven asserts that if his team analyzes both systems, they can create a strategy that will allow industries to move between electrical systems and hydraulic systems in a more compact and efficient manner than today. Additionally, Van de Ven’s team sought to reduce the number of intermittent hydraulic loads in an attempt to reduce energy loss. The primary application where the team feels their project’s success would benefit is the aerospace industry. Robotics could also use a new development in this area as Van de Ven is convinced electro-hydraulic systems are a long-neglected area of exploration for roboticists. Further in the future, the team is also convinced the push toward zero-emission vehicles creates an opportunity to develop a more efficient hydroelectric fuel cell.
»
PROGRESS With the goal of creating the linear electromagnetic piston pump, Van de Ven plans to reduce the current five-step electric to hydraulic conversion process to a three-step conversion process. His team estimates that a system of six piston pumps will effectively minimize slow ripple and improve overall efficiency. The team’s approach states that the fewer components in a conversion process will not only reduce the weight and volume, but will also
improve the control bandwidth. By seamlessly integrating in both directions, they can also cool the electric motor and electric drive. This will lead to an increased power density. The team also decided to incorporate newly developed wide band gap MOSFETS which enables them to see a faster switching frequency and higher efficiency and power density in the pump.
»
NEXT STEPS Although the project is in its infancy, the plan moving forward involves a two-year research strategy. In Year 1, the team will focus on model development and prototype design. The tasks include defining the design requirements, constructing the first-order models, increasing model details to inform that design, and selecting prototype parameters in order to optimize the design. In Year 2, the focus will shift to creating a laboratory benchtop prototype. The tasks required to make this a reality include fabricating a prototype machine, conducting experiment testing, and testing the hardware-in-the-loop. As the project develops and new findings affect changes to the research strategy, Van de Ven asserts that the team will relay their progress to the fluid power research community on a regular basis. He also invites industry researchers and fluid power SMEs with expertise in “drive cycle” data for HST charge circuits in various applications to contact him at vandeven@umn.edu if they’d like to weigh in and share their thoughts on how his team can adjust their strategy to optimize their model.

THEME PARK
THRILLS OWE MUCH TO HYDRAULICS AND ACCUMULATORS
By Jeffrey Sage, Product Sales Manager - Accumulator and Cooler Division, Parker Hannifin
Most people enjoy theme parks as a place to get away from work, but for those in the hydraulics industry, they are a place to demonstrate their expertise. Behind many of the rides that make your stomach drop or your eyes blink in amazement, accumulators are picking up the stresses and enhancing the performances of hydraulic technology. Behind the scenes, there is complex machinery that must run precisely and smoothly to ensure safe and reliable operation. Whether you are splashing through water, sailing above the tree lines, or being wowed by animations and simulations, powerful equipment that depends on the science and engineering of hydraulics is enriching your activities. And many of these large, powerful hydraulic systems rely on accumulators, hidden from the public view, but critical in their roles.

Bladder Accumulator
Piston Accumulator
THE ROLE OF ACCUMULATORS Typically, accumulators installed in hydraulic systems store energy to either provide an extra boost of power, or absorb energy to smooth out pulsations. Accumulators used in theme parks are gas-charged, and are either bladder accumulators or piston accumulators. Bladder accumulators are cylinders that contain a rubber bladder (See illustrations above). Hydraulic oil is kept under pressure when the bladder is inflated with non-flammable compressed gas, often nitrogen. When a ride needs a quick burst of power, a valve opens and releases the pressurized hydraulic fluid. A video of this process can be viewed at https://youtu.be/RMDE5v3ouN8. Piston accumulators are metal tubes with an enclosed piston. One side of the piston is charged with a pressurized gas and the other side with hydraulic oil. When the ride requires additional power, the pressurized gas pushes against the piston, which forces hydraulic oil back into the ride’s power unit. A video of this process can be viewed at https://youtu.be/1GBHtYqoznk.

Accumulators often play valuable roles in hydraulic systems that power rides for a variety of reasons. As you can imagine, moving multi-ton cars, coasters and props, often times with rapid acceleration requiring extreme bursts of force. Delivering this concentrated force is taxing on hydraulic systems and can cause jerky movements. Accumulators work to absorb these extreme pressures and movements, store energy, and keep performance consistent – delivering the extra “push” when a hydraulic system needs it. Often there are many accumulators used on each ride. For example, on motion-simulator rides, which have become quite popular since the 1980s, many accumulators are used. These are amazing rides where people feel all the shakes, rattles, and rolls depicted in a movie shown on a large screen. A big surge of energy is needed to move the platform. On one of these motion-simulator rides at a popular national theme park, there are 24 platforms, each with banks of 10-gallon bladder accumulators. Each time the platform moves, a quick burst of energy is needed. These accumulators provide the high acceleration needed to make the ride exciting and memorable.
SAFETY FACTORS
Safety, of course, must be at the forefront of manufacturing accumulators. A ride that breaks down can cause injuries or worse. Most bladder accumulator failures are from the bladder failing so many companies—like Parker Hannifin—go the extra mile to minimize that issue by making their own bladders for quality control reasons. Knowing how important the chemical process is in the making of these bladders, companies often have their own chemist, who buys the rubber and mixes the bladder compounds. With everything controlled and created in-house, this helps them produce accumulator bladders that are of the highest quality and reliability. And when a piston accumulator fails, it is typically a result of a leak in the rubber seal located on the outer circumference of the piston. A proper functioning seal separates the gas from the oil. Gas molecules are very small and can penetrate through the rubber seal. Companies, then, apply their expertise in rubber composition to develop seals that minimizes the gas permeation, thus extending the life of the piston accumulator. The next time you’re at a theme park waiting to ride, we hope that the greatest energy is the energy of the moment. However, you might take a moment to appreciate the extreme amounts of force and energy required for your favorite ride to give you a hair-raising experience.

THE IMPORTANCE OF
FLUID
By Robert Ihrig, Applications Engineer – Filter Systems, Hydac, Anthony Maiolo, Applications Engineer – Utility, and Timothy Rodman, Marketing Supervisor, Schroeder Industries
CLEANLINESS HEAVY MACHINERY? MORE LIKE HEAVYWEIGHT HYDRAULICS! In today’s modern equipment, simply maintaining fluid cleanliness in hydraulic systems can reduce the cost of operation by as much as two-thirds. This means improved uptime, higher performance levels, and reduction in cost of operation. While operators rely on modern equipment to get the job done, what does modern equipment rely on? The answer: A highly efficient, reliable, and robust fluid power (hydraulic) system.
OLD SCHOOL VS. NEW SCHOOL Fluid power, as an energy source, can produce high power and higher forces in small volumes compared to electrically driven systems. Now, an average front loader can lift upwards of 2,000 lbs. at a time.
IN TODAY’S HEAVY MACHINERY
THE TIMES HAVE CHANGED Contemporary equipment like electrical controls are widespread in automated systems. The use of measuring, sensing, and controlling devices requires that the fluid be maintained at consistent cleanliness and temperature levels. Manufacturers are keeping up with this demand by utilizing newer technology in machine parts. This technology can help reduce material waste, promote improved production times, and the overall quality of work. With the demand for higher efficiency, tolerances have become tighter, and parts have become smaller. Tolerances as tight as .0001 of an inch are more frequently used. With that tight of a tolerance, contamination in fluids (even 10x smaller than a grain of table salt) can negatively affect critical system components. Fluid power system repairs represent a significant portion of annual maintenance dollars spent
today. With electric controls and the tolerances becoming so tight, contamination becomes an enormous cause for system repairs. As a way to help combat these issues, we needed a system to measure contamination—which was universal—and readily adaptable across many industries and market sectors today. To overcome this, industries now adhere to the ISO 4406 Cleanliness Standard.

BUT MY FLUID LOOKS CLEAN
Often times, the contamination causing the most issues in your equipment is not of a size easy to view by the human eye. Most everyone’s fluid “looks clean,” but is in fact riddled with contamination. Particulate contamination of all sizes can originate from many different sources, such as: • Oil containers delivering “new” oil • Original equipment delivered by the OEM • Poor cleanliness standards maintained during equipment operation (e.g., ingression of contaminant from damaged seals or dirty breathers)
WHAT CAN I DO TO PREVENT SYSTEM SHUTDOWNS CAUSED BY CONTAMINATION? By using the ISO 4406 standard to understand fluid cleanliness for controlling contamination and wear in hydraulic systems, operators keep their systems running efficiently and operating “like-new.” In most cases, the implementation of a cleanliness standard is a huge step in the right direction. We’ve broken it down to 7 steps for adhering to this cleanliness standard on the next page.

STEP 1 Determine the operating pressures of the system you are applying the cleanliness standards to. While determining the system’s pressure, you must keep in mind these three factors:
• The environment the system is going to be operating in • Where a filtration solution will be installed • The duty cycles required
STEP 2 Determine the flow rates within the machine in question. The questions you need to ask are: • What are the max and nominal flow rates that my system sees? • Is there any type of surge or back flow present in my system? STEP 3 Define your most critical component. Identify what component is used the most, and requires the cleanest ISO code reading (refer to Fig. 3). STEP 4 Use the ISO code defined in Step 3, and match it to a micronrated filter element. There is printed literature that best recommends the micron size needed and in direct relation to the ISO code found in Step 3: • 19/17/14 = Z10 filter media • 18/16/13 = Z5 filter media • 15/13/10 = Z3 filter media STEP 5 Recognize the fluid you are using. The type and viscosity of the fluid that runs in your system will help you determine the seal
type and media type needed in a filtration solution, as well as the contamination type (i.e., metal, rust, water, etc.) you are experiencing the most problems with. STEP 6 Determine your maximum operating temperature. Temperature will affect the fluid viscosity. Viscosity will affect the differential pressure, which is important in selecting the proper filter housing size. STEP 7 Piece it all together. With all the information gathered from Steps 1-6, you can calculate the overall system differential pressure. Your solution should result in your clean element pressure drop being less than half of the overall bypass cracking pressure at normal operating temperature and flow. Today’s modern equipment sure does have a lot to worry about. It’s best that OEM hydraulic designers and MRO fleet owners do not let contamination become a problem.

Vehicle Challenge Mentors Connect with University Students and Help Them Succeed
»
THE NFPA FLUID Power Vehicle Challenge is a competition that challenges college engineering students to redesign a traditional bicycle using hydraulics as the mode of power transmission. This is NFPA’s third year of organizing this competition, and during this time we have seen students’ discovery, energy, innovation, and frustration. We have seen great advice and great connections. We have seen generosity in the middle of a highly competitive race and team spirit that never dies. All of this while supporting learning and the growth of fluid power industry knowledge. Each year we look to improve resources, so starting this year, each university Vehicle Challenge team was assigned an NFPA industry member mentor. The teams can get competition points for checking in with their mentor at least four times throughout the program and submitting a summary of their discussion. Mentors can help with things like vehicle bike design and schematics, component selection, assembly questions, and final adjustments before the competition. They can also be judges at the competition. We are seeing that this program is providing much-needed resources and advice to the teams while giving NFPA members access to very creative engineering students. One of the students participating in the Vehicle Challenge said this about the program: “All in all, we see a lot of benefit in the Mentor Program and the new thoughts it will curate for this year’s competition. We have enjoyed our experience thus far and we look forward to new ones on the horizon.” NFPA’s workforce strategy is to help increase the number of university students educated in fluid power and connect them to NFPA members and careers in the fluid power industry.

NFPA’s Robotics Challenge Scholarship Drives Students to Use Fluid Power
»
THE NFPA ROBOTICS Challenge is a scholarship program that supports of the missions of FIRST® Robotics and the National Robotics League (NRL). NFPA offers one merit-based scholarship for $40,000 ($10,000 per year for four years) to a high school senior who participates as part of a 2019 FIRST® Robotics or NRL Competition Team. This scholarship may be used to study engineering at any accredited technical college or university in the United States. The goal of this scholarship is to bring awareness of fluid power options in robotics to high school students and to stimulate increased use of fluid power products in these competitions. By getting more students working with fluid power at a young age and seeing all of its benefits, more students considering fluid power careers when they enter a tech school or university. In its third year, the NFPA Robotics Challenge Scholarship gains more notability every year. In our first year, we received 85 applications, and last year we received 105 applications. Every year the number of teams using fluid power increases! The FIRST® Robotics Competition kicked off their competition season on January 5 when they released the game/challenge information for this year. The theme, Destination: Deep Space, offers many opportunities for fluid power to be used in a winning robot! How can you help? If you mentor a FIRST® Robotics or NRL team, work with them to incorporate fluid power into their robot and encourage them to apply for the NFPA Robotics Challenge Scholarship. The application is available at http://nfpahub.com/fpc/ robotics-challenge.

1994-2019: 25 Years of Innovation By Cindy Cookson, Director, Global Product Line – Hydraulics, Gates Corporation
»
THE GATES CORPORATION was founded 108 years ago in 1911, and today, it is a global manufacturer of innovative, highly engineered power transmission and fluid power solutions. The hydraulic hose is just one product in Gates’ broad portfolio of industrial solutions, which are sold in 128 countries for diverse channels and applications. Hydraulic hoses are a critical component of machinery and equipment in industries with demanding performance requirements such as agriculture, construction, forestry, mining, and more. The G2 hose, a stalwart of the Gates Hydraulics portfolio for decades, was designed for use
in high-pressure hydraulic lines in applications across agriculture, energy, transportation, and other demanding industries, and met the historic SAE 100R2 specification. Building on the company’s expertise in materials science, the M2T hose was launched in the 1990s as a compact alternative to G2. M2T set a new standard for wire braid performance by using novel wire reinforcement designs to achieve high pressure performance in a smaller package. Since there was no formal industry standard at the time for this new compact hose construction, Gates collaborated with industry partners and the Society of Automotive Engineers to formalize
such a standard, and the SAE 100R16 specification was published in 1994. Since then, mobile fluid power applications have become more complicated as power output requirements on these systems have increased. At the same time, the available space in engine compartments has shrunk for a number of reasons: industry regulations have limited the overall space available; both environmental considerations and performance needs have driven the introduction of more systems; and added system features like emissions controls, hydrostatic drive lines, and climate control systems compete for space in the drive
We know the rigors of the hydraulics industry and have the components to work - a full range of ball valves, check valves, ow control valves, anges, adapters, bar manifolds, pressure gauges, snubbers and SSW power unit components for engineers and professionals.

compartment. These factors have led to more systems that require advanced technology, while also introducing increased complexity in a smaller space, all of which has driven Gates to further innovate its hose products throughout the last 25 years. Gates introduced its next generation of premium hydraulics in 2018 with the Gates MegaSysTM MXT™ family of hoses that set a new standard for modern fluid power systems. MXT is a shining example of Gates’ commitment to innovation, leveraging technology and materials science to push boundaries and solve problems for customers. Where M2T was a more compact version of G2, MXT is a more compact version of M2T, solving customer challenges such as space constraints, challenging hose routing issues, and system weight. The patent-pending innovations that enable MXT include breakthrough design models for the hose reinforcement that enable wire reinforcements to work more efficiently. MXT also
leverages modern materials to meet or exceed a wide range of global industry standards. It is fully compliant with SAE 100R16, and also performs at other SAE, EN, and ISO standards to cover 90% of wire braid hydraulic applications. MXT weighs up to 30% less, which improves fuel efficiency, allows for easier handling, and reduces shipping costs. MXT was also tested to exceed 600,000 impulse cycles — three times greater than industry standards. Additionally, it is 40% more flexible than legacy Gates products like G2 and M2T, which reduces the speed of installation because the hoses are easier to route — a benefit that also improves ergonomics for installation technicians.
Gates as an organization has also changed during the last 25 years. Gates’ materials science expertise has evolved its portfolio far beyond rubber compounds and have led to increased product performance. Additionally, innovations in manufacturing processes deliver reliable products that meet evolving market needs with a global manufacturing footprint. Gates continues to accelerate the next 25 years of fluid power growth with innovations that address the needs of evolving systems. From performance upgrades to operations improvements to green technologies, Gates is driven by possibility.

AIR TEASER
New Problem:
Sizing a Two-Stage Piston Air Compressor By Ernie Parker, CFPAI, CFPSD, CFPS, CFPMM, CFPMT, CFPMIP, CFPMMH, CFPMIH
S
Given: A two-stage air compressor with an intercooler System Pressure: 120 PSIG. Each stage raises the pressure 60 PSI. Initial air temperature: 70° F Entering air temperature at second stage: 90° F First stage: 3” diameter x 4” stroke Neglect the volume of the intercooler. After the first revolution, the air is just passing through. Find the required diameter for the second stage with the same 4” stroke.
olution to the Previous Problem: Car Hoist
This problem is to show the additional air consumption needed when the air over oil tank is low with oil that is used in car garages for the car hoist. Solving with a full tank of oil: Area of cylinder: 10² x .7854 = 78.54 sq. in Stroke is 8’ 8’ x 12” = 96” Volume of cylinder: 78.54 in² x 96 in = 7,539.84 in³ Cubic feet = 7,539.84 / 1728 (cu. in. / cu. ft.) = 4.36 cu. ft. Compression ratio (C.R.): 100 + 1 = 7.8 C.R. 14.7 SCF: 4.36 CF x 7.8 = 34 SCF when the tank of oil is full when starting to lift Air/Oil Tank is only half full of oil when starting. We now have to pressurize the air/oil tank before the hoist will start to lift Volume of cylinder is 4.36 CF Volume of air/oil tank is 4.36 x 1.5 (size of air/oil tank) = 6.54 CF Half full of oil means we need an additional volume of air that equals 6.54 /2 = 3.27 CF Volume of air needed is: 4.36 (cyl.) + 3.27 (tank) = 7.63 CF SCF = 7.63 x 7.8 C.R. = 59.51 SCF Note: If the tank of oil is only half full, 59.51 / 34 = 1.75 times as much air is needed every time the hoist is fully raised.
