B

efore I purchased Ace Hydraulic, I was hired to set up two warehouses for a large farming company in the southern San Joaquin Valley in California. An outside salesman from Ace Hydraulic stopped by to make a sales call as I was setting up. He made recommendations to stock bulk hydraulic hose and fittings and a crimping machine, which we purchased, considering the farming had well over 150 pieces of mobile equipment. As the almond, wine grape, and pistachio harvests were coming near, the mechanical harvesters needed servicing. The salesman suggested that, once a week, he would pick up cylinders, valves, pumps, and motors for repair and bring back those repaired components the following week. How ironic that I was a customer of the same hydraulic business I eventually purchased!

Today, we continue to field two outside salesmen. One salesman exclusively calls on the oil production area, which keeps him busy because our county is the nation’s number one oil-producing county in the lower 48 states. The other salesman calls on the agriculture and trucking industries. Trucking includes construction, municipalities, waste disposal, and bulk carriers. One of our salesmen has been with us for 22 years and the other for 15 years.

Over the years we tried virtually every combination of financial compensation for two salesmen. We tried salary, which didn’t work. Then we tried salary plus commission. We had manipulated those commissions every which way possible. Today the pay structure is straight commission. The more the salesman sells, the more he makes. Commission is calculated by taking the gross profit earned from assigned accounts and paying 15% of that gross profit figure as commission. These salaries fluctuate based on the peaks and valleys of the different industrial business cycles. We supply each salesman with Ford F-150 pickups with maintenance and fuel.

To put all of this into perspective, our company is structured with two distinct profit centers. A portion of profit is derived from front counter sales. The other portion of profit is derived from our repair shop

activities. The sales split is approximately one-third from the shop and two-third from the counter sales.

Our two salesmen concentrate on placing hose crimp machines, which generate long-term repeat business.

They introduce new products to their customers and assist the customers with new applications or specifying different options to solve a nagging problem. On occasion they bring in a pump or cylinder for repair.

As the salesmen acquire new accounts, we will put the new accounts under their assigned accounts. If they lose an account or stop calling on it, we put that account under the house account category. The salesmen structure their sales call pattern on time and territory management. They first classify each and every account according to their annual gross sales potential. They then call on their highest potential accounts once a week. They call on their accounts with less potential twice a month and the accounts with the least potential once a month. This is called “fishing where the fish are.” We do not allow them to call on small accounts. Fielding salesmen is an expensive proposition. Their time is valuable.

Inherently, managing outside salesmen is like herding cats. Good salesmen must be disciplined, self involved, greedy, have product knowledge, and be structured. So often I’ve heard it said that, “He would make a good salesman because he sure can talk.” From my perspective, a good salesman must be a good listener. He must wait for the customer to completely finish his opposition or comment, and then must have a well-prepared response. He has to always ask for the sale. Once you get good salesmen, hold onto them. They are like gold. They can bring sales from places you would never have expected. I’ve also heard, “Too often we have found that we are training salesmen for our competition.”

Is it worth having outside salesmen calling on accounts? Absolutely, yes. They obviously bring in new business, keep our name in front of our customers, and inform our customers of new products. They are spies for us by seeing what the competition is doing, and they service accounts on a regular basis.

Orifice Flow

This will be a slightly different approach to our familiar column.

The orifice flow approximation program allows you to enter inlet pressure, outlet pressure, and orifice diameter. From this data, the program will provide the following: • Flow in SCFM at those conditions • PSIA equivalent absolute pressure Please visit www.fluidpowerjournal.com • Diameter squared to get a direct link to the program.

• Area • Cv • Flow in SCFM • P2/P1 Ratio (The flow is sonic when this ratio is 0.528 or less.)

Cv = 1 when the orifice diameter is 0.1833. Then with the flow for a Cv or 1 for any pressure ratio, you may multiply this flow by the Cv of any valve or device and get the flow of that unit. With the pressures set to your condition of interest and the diameter set at 0.1833, the Cv = 1.

If, for example, the flow was 26.7 scfm and your valve had a Cv of 2.75, then 26.7 scfm x 2.75 = 73.4 scfm. You have a complete Cv to SCFM table at your fingertips.

To do this in reverse, change the orifice diameter (trial and error) until the Cv is equal to whatever Cv you are interested in. Now with any pressure changes, the flow will be approximately equivalent to the flow with the Cv that you selected.

To debunk the myth that flow will not change when the orifice flow is sonic or choked, set the pressure ratio P2/P1 to conditions that show 0.528. If you decrease P2, the flow won’t change. If you decrease P1, the flow will decrease. If you increase P1, the flow will increase.

The Future of

Braking Is Here

It’s typical to hear talk of the future being “here” or “now” when assessing the future of a given industry, particularly one where technology plays a key role. Setting aside all metaphysical discussion about what constitutes a changeover from the present to whatever comes next, these conversations tend to take place in the context of what’s currently possible. Sure, some ideas may be legitimately futuristic, but most are firmly rooted in present-day knowledge and capabilities.

With this in mind, it would be incredibly underwhelming to simply say that the future of off-highway vehicle braking technology has arrived. It’s more apt to say the present is always evolving, with new advancements constantly being developed.

Ultimately, however, the changing world of braking has far less to do with when, and everything to do with what. That is because the braking industry has actually moved beyond the niche of brakes and related components, and is now focused on how brakes can become more integrally connected with the operation of a vehicle as a whole.

Getting Brakes Connected In the past decade, electrohydraulic braking systems —including ABS and traction control — have grown increasingly popular, due largely to the vehicle design flexibility and performance advantages they offer. The industry has seen several other instances of intelligent machine controls unrelated to braking over the years as well.

But what all of these technologies have typically had in common is that they’ve existed as standalone, point-to-point functions that have not been integrated together. The present and future of braking are all about taking the next logical step — getting fully connected and finding ways to embed intelligence throughout a machine so that vehicle systems are totally integrated and optimized.

ABS is a good example to examine. Historically, ABS has worked through a relatively simple form of connectivity. An ABS fault might send a message through a CAN bus, perhaps activating an ABS fault light on the vehicle dashboard. No interaction with other vehicle functions would take place. Everything occurring with the ABS would basically be self-contained.

Now, ABS can be programmed to exchange information with other vehicle systems, such as a hydro-

static drive. If one or more wheels start to lock up, the brake system can tell the hydrostat that an ABS event is occurring by delivering a message for the transmission to disengage, thereby increasing ABS performance and preventing the engine from stalling. The vehicle controllers can also use other status information like vehicle speed for interlocking and other safety features.

There are multiple benefits to machine integration. The first and most obvious is improved vehicle performance. Lower cost is another. Although it is unusual for a technology improvement to result in a cost reduction, using just one electronic system — instead of several — to collect and share all vehicle function information often results in cost savings. Fewer components and reduced weight also provide a tangible benefit.

Innovate to Integrate In addition to enhancing integration for existing brake system technologies, engineers are branching out from their traditional areas of expertise. For example, rather than focusing solely on brake systems and components, manufacturers are expanding their services to cover the full gamut of vehicle stability control in order to better support their OEM customers.

The basic goal of designing a brake system is to achieve a specific stopping distance based on vehicle weight and other parameters. When looking at electronic stability control, more factors have to be taken into account. Stability control may be utilized to help a driver keep a vehicle under control in extreme driving situations like over- and under-steering. This requires an evaluation of a vehicle’s dynamic capabilities through the use of accelerometers, gyroscopes, and other sensors that aren’t typically found on an offhighway vehicle. Manufacturers also prefer to perform a vehicle computer simulation to evaluate stability control performance prior to deploying the technology to a vehicle.

From there, integration can occur just as it does with technologies that are related strictly to braking.

An electronic stability control system may communicate with a vehicle’s electronic suspension system. It might apply a single brake or multiple brakes depending on whether the machine is following the driver’s intention to move in a certain direction. Many other systems and information can also be utilized to assist with stability control.

Regenerative braking is another popular technology that is helping to make vehicles more energy- and fuel-efficient by storing energy generated during the braking process and later re-using the stored energy for driving. The technology is an additional example of the need for vehicle integration and system communication, as regenerative brakes will encounter situations where standard service brakes must take over.

More Involvement One side effect of the proliferation of total machine integration is that brake manufacturers must be willing and able to become involved earlier in the overall vehicle development, rather than entering the picture at a later point to implement a standalone braking system.

Even for independently operating functions, controls and components usually need some degree of tuning along the way. Those tweaks can be related to actual performance or simply be a packaging modification to ensure that a component physically fits where it belongs. When these same components are required in an integrated scenario, it is clearly a more efficient design process to figure out how every vehicle system will work together from the start and then engineer those systems accordingly.

The move toward integration also means that in many cases, an “off-the-shelf ” braking component will not be a viable solution for an intended application. For companies that have spent decades providing specialized, custom braking components, the learning curve promises to be much shorter than for manufacturers who have historically delivered high-volume, generic options.

Rooted In Safety Braking is inherently all about safety — mitigating risk to primarily prevent accidents, loss of life and injury, and to help avoid damage to expensive vehicles and equipment. Safety has been and always will be of the utmost importance, but for decades most off-highway vehicle industries were exempt from a large

number of vehicle safety standards because machines simply didn’t move quickly enough for certain braking guidelines to apply.

With new technology advancements, off-highway vehicles are becoming faster. Clearly this fact has the attention of braking component providers, as increased speeds are creating new challenges for vehicle design. Faster vehicles must conform to certain Safety Integrity Levels (SIL) and other safety standards that are not new, but are more critical for faster equipment.

Because such standards didn’t previously apply when off-highway vehicles were FIG. 3: Great Lakes Power's ST35 slower, braking manufacturers actually have to educate their OEM customers about straddle carrier features a MICO certain requirements. Things get even more interesting when factoring in the high electrohydraulic brake degree of integrated software and other electronic capability built into an optimized system, among other vehicle. In essence, integrated vehicle design has created a two-way street where sophisticated functions. both braking and equipment manufacturers need to become schooled in the other’s traditional area of expertise.

Tomorrow Keeps Arriving The off-highway equipment industry is extremely dynamic. Environmental pressures like Tier 4 requirements and wildly fluctuating markets can create daily challenges. Given the degree of difficulty in many cases, it’s quite simple to see how decisions might be made because a particular solution is the easiest or cheapest available.

Fortunately it is also an industry that is full of problem-solvers — engineers and other leaders who are driven to deliver a new wave of technology to improve vehicle safety and performance. Braking manufacturers are very much at the forefront of the current wave and will play a big role in the evolving future. Upon seeing how far technology has come with electrohydraulics and other advances, it’s ironic that even braking experts might have to admit that there’s just no stopping what’s coming next.

Changing a Vacuum

Cup

By Daniel Pascoe

acuum cups are used throughout industry for so many applications that the list would take up most of this page. Fundamentally, vacuum cups are used to grip a product while it is lifted, clamped, or conveyed from one place to another. There are many different designs and styles available from numerous manufacturers in various materials and compounds. This article explains what basic criteria should be understood to successfully change a vacuum cup for an alternative model.

One of the biggest mistakes made by a salesman in selecting a vacuum cup for a customer is trying to find or apply an exact replica of the one that is already in use. Just because the cup is working does not mean you can’t offer a better alternative based on type, size, or even cup material. Basically there are three types of vacuum cups: flat, bellows, and multiple bellows, which are usually round in shape. Of course there is sometimes the need to use specific shapes determined by the item being picked up. Fig. 1 shows a doorframe blank where oval cups are used to grip the window frame. This oval cup choice maximizes surface area compared to numerous round cups. However on the larger surface, round cups are an easier choice, and round cups are by far the most popular in use today.

The dimensions and features of the internal neck (illustrated in Fig. 3) of the vacuum cup is the most important dimensional information to be aware of when offering an alternative cup. If the new cup fits the existing fitting, then all is well. If it does not, however, the next most important feature is the fitting thread. Fitting threads are normally standard, being male or female NPT or BSPP. If the alternative manufacturer can offer a similar cup with a fitting thread that is the same as the competitors, then the complete assembly can be changed out.

12

off-highway directory 2012

Fig. 2 shows a typical bellows cup. The images show the cup by itself, its intended fitting, and the complete assembly. This fitting is suitable for a variety of different cups, but if the salesman is representing a different manufacturer, the chances are that the fitting will not be suitable for the new cup brand.

Of course there are cost limitations to this, as you would have to supply new fittings, whereas the competitor, of course, only needs to supply a rubber cup.

Consideration of the project should be made in this situation. If the customer is going through nearly 1,000 cups a year, for example, it’s an attractive opportunity to sell your brand of vacuum cups. If there are 80 cups in place (each cup being replaced 12 times per year or every month), then you will need to supply and probably cover the cost of 80 fittings. The cost of the fittings versus the profit on 1,000 cups will determine if this is viable.

Overall cup height (Fig. 3) is also an important dimension. The machine is probably set up accurately based on the approach distance to the product being lifted. If the new cup choice is 1/2-in. (12-mm) longer, can the machine operator change the approach distance, or indeed do they want to be bothered with a machine setup change? If the financial savings are there, more likely the user will make the one-time machine set up.

This exercise is purely commercial and certainly commonplace in vacuum cup sales activity. However, a

lot of applications may warrant different vacuum cups purely because the ones currently in use are not the most suitable for the application. When handling cardboard boxes, a very common vacuum cup application, different machine builders select different materials.

This is normally based upon an historical purchasing habit or simply availability from their chosen supplier.

However, just because the user has been using a particular vacuum cup for many years does not mean an improvement cannot be made. When handling cardboard boxes, for example, consideration should be made to the cup material. Silicone vacuum cups are a good choice due to the low Durometer (hardness), which allows them to seal very well against the uneven cardboard surface. This allows a higher vacuum level, and therefore a smaller vacuum pump or generator can be used, as leakage between the cup and product is much less. That said, silicone has a lower wear resistance than a Nitrile-based compound, so the cup replacement will be more frequent.

Some cups are made from a PVC compound, which is a plastic-based material. Although they are hard wearing, they work harder instead, which means life is shortened, particularly in a compressing cup such as bellows model. Because of this, this type of material has a low initial cost for the machine builder, but user ownership could be a lot higher than a rubber compound model due to frequent cup changes.

Cup diameter is often the first cup feature to be referenced when selecting a cup from a manufacturer’s catalogue. However, the cup diameter is rarely critical in most applications. Cup diameter and vacuum level determine the lifting capacity of the vacuum-lifting system. A small vacuum cup has a tremendous holding force, which very rarely relates to the weight of the product being handled. For example, a 2-in. (50-mm) diameter vacuum cup has a theoretical holding force in excess of 25 lbs at 20"Hg. If this was used to hold a 20-lb box, the theory works. Of course the problem would be that the box deforms when picked up in the center by a single cup. Therefore, numerous cups offering support across the top of the box will be a successful system. If six Ø50mm cups were used, the

holding force at 20"Hg would be in excess of 150 lbs.

The point is that the cup diameter is rarely the defining feature of a successful lifting system. If the sales person offered 40-mm diameter cups to replace the existing 50-mm cups, the holding force would still be in excess of 100 lbs, and the customer would probably save money in the process.

The style of vacuum cup is also not that important, in respect to being exactly the same. A 1½ bellows cup as shown in Fig. 3 can most likely replace a 2½ bellows as shown in Fig. 4, unless the application has definitely determined that a longer bellows is more suitable such as it requires a longer independent cup “lift” when vacuum is applied. Understanding the application is very important when changing the cup style. If a test is required, then this should be done, of course. A sales person that has different cup samples with them when looking at a cup application is certainly ahead of the game.

The most important part of a vacuum cup when offering a different model, as explained at the beginning of this article, is the neck diameter or mounting feature. Will the cup fit on the cup fitting? If not, can you use a different size cup that will fit, or can you, based on initial cost, offer a new fitting suitable for your cup choice? Is the customer using the correct material for the application? Is the cup wearing quickly or splitting where it connects to the fitting? Is the cup applied correctly or was it a choice made purely on initial cost?

More often than not, a selection of less than 20 cups in your complete portfolio is more than enough for most applications. The reason for there being so many cups in existence is the same as most simple technologies: independent, international, creative R&D departments and the ever-present re-invention of the wheel.

This article is intended as a general guide and as with any industrial application involving machinery choice, independent professional advice should be sought to ensure correct selection and installation.

Pneumatic Technician (PT) The International Fluid Power Society is the only organization that provides comprehensive technical certification offerings for all professionals in the fluid power and motion control industry.

IFPS certifications are portable and are recognized industry wide. IFPS certification tests provide an objective, third-party assessment of an individual’s skill level. Individuals who successfully master the Pneumatic Technician’s level of competency are issued the credential CFPPT signifying an elevated status in the workforce.

IFPS defines a Pneumatic Technician as an individual that fabricates, assembles, services, maintains, and tests pneumatic equipment. The Pneumatic Technician can calculate force and motion control systems and is able to follow blueprints and schematics with ISO standard pneumatic symbols. All Technician certifications require a three (3)-hour written and a three (3)-hour Job Performance (hands-on) test. If you’re interested in testing for the PT level certification, registration information can be found at www.ifps.org.

IFPS – International Fluid Power Society

IFPS Chapter 49 Now Offering Fluid Power Certification Review Sessions The Central Florida chapter of the International Fluid Power Society (IFPS) invested in an IFPS Job Performance kit enabling the chapter to offer Mechanic and Technician review courses and test dates for the IFPS Job Performance Test.

Gwyn O’Kane, CPFCC, CFPMHM, chapter secretary, along with Greg George, CFPAI, who is responsible for training, felt is was important that the chapter get behind certification as this is of value to members, the chapter, the IFPS, vendors, customers, and for the industry as a whole. “We presented a proposal for the purchase of the job performance kit at our last meeting and the members of the chapter voted unanimously that this would be a great asset,” said O’Kane.

Scott Gower, CFPS, chapter president, said, “This is the next level of purpose for the chapter. It shows a commitment to the IFPS certification program and it provides another tool for chapter members to use to promote certification with the industry.”

Greg George, CFPAI, chapter trainer, is a Fluid Power Specialist and Accredited IFPS Instructor, and with the help of other chapter members, Chapter 49 hopes to offer, promote, and provide 2-3 dates each year for a maximum of 12 (twelve) students in each course. “We will be offering a 16-hour review course followed by a test date. For locals we will offer a review course over eight weeks with two-hour evenings, and in order to reach a larger audience, we will offer a two-day review course followed by a test date,” said O’Kane. “In addition, we want to make it easier for members to get certified, and the great thing about the Job Performance Test is it then enables you to go on and do six (6) different certification written tests, which can be provided at many local community colleges around the U.S.”

For details on the 2012 dates being offered by Chapter 49, check out the IFPS website at www.ifps.org. You can contact Chapter 49 and subscribe to their newsletter by e-mailing Jamie Vokes, CPFCC, at florida49er@ifps.org.

FPEF – Fluid power educational foundation

Fluid Power Educational Foundation Key School Students Chosen for Pilot Internship Program Two students from the Fluid Power Educational Foundation’s (FPEF) Key School at Northwest State Community College in Archbold, Ohio, have been chosen for the pilot student internship program at Perfection Servo of Batavia, Ill. Bradley Wagner and John Weaver, both studying Mechatronics at Northwest, were selected from five applicants representing two different Key Schools to fulfill the internship program this coming summer in Illinois.

“The FPEF hopes to have glowing reports of a successful internship program, both from Perfection Servo and the two students,” said Liz Rehfus, CFPE, CFPS, FPEF chair.

Perfection Servo decided to initiate this pilot internship program when they found that finding students with a background in fluid power led them directly to FPEF Key Schools. Interns will serve at the company for nine weeks, including four different work rotations. Each intern will spend four days per week for three weeks in prep, teardown, or test areas. In addition, each will spend one day per week paired with an experienced hydraulic repair technician. Perfection Servo is generously providing a rooming stipend for each student, as well as paying them for 40-50 hours of work each week.

“A successful program this summer will allow us to provide additional internships in the future,” said Karen M. Hossfeld, HR manager, Perfection Servo.

Perfection Servo has over 30 years’ experience in the remanufacturing and repair of both hydraulic and electronic components for many OEMs that use fluid power products in their businesses. Perfection Servo has developed an in-depth series of procedures to catalog, evaluate, estimate, repair, test, and return-ship the customer’s equipment with the highest quality craftsmanship.

In recent years, the rising demand for energy and the increasing concerns of the environmental impact have triggered more strict governmental regulations on fuel economy and emissions for personal and commercial transportations, as well as other mobile applications. The new CAFE (corporate average fuel economy) standard in the U.S. almost doubles the fuel economy by year 2025. Similarly, the fuel consumption of the heavy-duty vehicles is required to reduce 20% by year 2018. Obviously, significant technical innovations are required to achieve these ambitious goals.

Contamination nightmare... or... and complex design of both the ICE and the hydraulic pumping system due to the dynamic operating requirements. An alternative approach is to supply fluid power using a free piston engine (FPE) with a linear hydraulic pump. As shown in Fig. 1, combustion in the right cylinder will push the inner piston to the left and outer piston to the right, which will compress the gas in the left cylinder and generate high-pressure fluid in the inner hydraulic chamber.

Similarly, combustion in the left cylinder will return the inner piston to the right and outer piston to the left. This configuration has the potential to significantly increase the ICE and pump efficiency while increasing system modularity. Specifically, the ICE efficiency can be improved with the variable compression ratio, advanced combustion such as homogeneous charge compression ignition (HCCI), and less friction due to a simpler design. The dynamic and modular nature of the free piston engine-driven hydraulic pump makes it very attractive for mobile applications by converting liquid fuel to fluid power on demand without a large energy storage device.

The proposed technology will not only revolutionize the automotive propulsion system, but can also be transitioned into different classes of on-road and off-road vehicles, heavy machinery, and power generation equipment. Given that hydraulic hybrid systems are well suited for heavy commercial vehicles, the technology could in the future be incorporated into commercial vehicle fleets. At the same time, retrofitting existing vehicles with the hybrid systems will allow for additional reduction in fuel consumption and emissions.

So far we have developed detailed models for the system, including the hydraulic model, the gas

can compromise hydromechanical efficiency. A seminal moment in the development of energy-efficient hydraulic fluids occurred in 1999, when Steve Herzog of RohMaz, Thelma Marougy of Eaton, and I drafted the NFPA Recommended Practice T2.13.13 – Viscosity Selection for Hydraulic Motors and Pumps under the guidance of Fluids Committee Chair Paul Schact of Bosch-Rexroth. This document provides a means of selecting the right viscosity fluid to assure hydraulic system reliability. From that moment, with the noteworthy leadership of Mr. Herzog and his colleagues of RohMax, energy-efficient hydraulic fluid technology

was launched. These products, many of which incorporate shear-stable viscosity index improvers, have been found to yield significant efficiency improvement in pump tests and field trials. Today, CCEFP members ExxonMobil and Shell are marketing energy-efficient fluids formulated with additives produced by CCEFP members RohMax, Afton Chemical, and Lubrizol.

While viscosity is certainly a key factor in hydraulic system efficiency, Project 1.G.1’s investigations with hydraulic motors from Eaton, Poclain, Parker Hannifin, and Sauer-Danfoss have shown that viscosity doesn’t tell the whole story. All of the oils in Fig. 1

have the same kinematic viscosity at 40°C, yet motor efficiency varies significantly from fluid to fluid.

When examining fluid-efficiency interactions in hydraulic motors, one soon realizes that multiple lubrication regimes are present. A handful of researchers in the CCEFP have teamed-up to unravel these interactions: • Boundary Lubrication: Mark Devlin and Jeff Guevremont, Afton Chemical • Elastohydrodynamic Lubrication: Scott Bair, Georgia Tech • Hydrodynamic Lubrication: Steve Herzog, RohMax • Static Friction: Ashlie Martini and Daniel Brant, Purdue University • Surface Texture: Bill King, University of Illinois at Urbana-Champaign (UIUC) These investigators found that improved motor performance at start-up may be obtained by formulating a fluid with low static and boundary friction coefficients while minimizing viscosity change at increased temperature and pressure. Bill King of UIUC is a relatively recent addition to the research team. We anticipate that his surface texture modifications to the geroler will uncover a whole new approach to improving starting efficiency.

Project 1G.1 is currently investigating tribofilm structure and chemistry in motors by comparing the tribochemical films formed in a reciprocating tribometer to those formed in an operating hydraulic system.

Hydrostatic Transmission Use in Wind Power Applications

By Brad Bohlmann, University of Minnesota

Wind power research is ongoing at the University of Minnesota to investigate and answer three questions: 1. Can wind turbine reliability be improved by replacing the conventional drivetrain with a hydrostatic transmission (HST)?

2. Is it possible to extract more energy from a given wind profile through the use of a variable HST? 3. Can a wind turbine with an HST drivetrain have a lower life cycle cost of ownership than a conventional wind turbine?

The work includes modeling and simulation and lab-scale testing of systems. The goals for the testing include validation of the modeling results and optimization of the system components and control systems.

The drivetrain technology under investigation is called a hydrostatic transmission (HST). HSTs

have been the dominant choice for off-highway propulsion systems for more than 50 years. In fact, they are installed in the vast majority of agricultural, construction, and forestry vehicles in use today. There are literally millions of HSTs currently in use worldwide in very demanding commercial applications where performance, durability, and reliability are critical.

Thus, the core technology of the system has a long and successful track record, and the wind turbine drivetrain technology proposed herein builds on that legacy of success.

Fig. 1 shows the main components of an HST. In the case of a wind turbine, a fixed-displacement pump converts the rotational motions of the wind turbine’s blades into fluid flow. This fluid flow is converted back to rotary motion by a variable displacement hydraulic motor that is attached to the wind turbine’s generator.

This type of HST is one embodiment of a continuously variable transmission (CVT). In a CVT, the ratio of the rotational speeds of the input (wind turbine blades) and output (wind turbine generator) components in the transmission can vary over a broad RPM range in a continuous manner without discrete gear steps. This allows the transmission to be used at speed ratios that can optimize system efficiency. In a wind turbine, this generally means allowing the wind turbine’s blades to rotate and their optimum tip speed ratio.

Several other unique features are enabled by the “fluid link” between the input and output components of the

HST. One is the ability to physically separate the input and output, such has having the hydraulic pump in the wind turbine nacelle, and the hydraulic motor and generator on the ground. Another advantage is that the fluid link provides more compliance, which reduces the shock loading and associated fatigue failures that occur in mechanically linked wind turbine systems.

Replacing the conventional, gearbox-driven drivetrain in a wind turbine with a hydrostatic transmission has the potential to simultaneously improve reliability and increase system efficiency. The result should be a lower cost of electricity. * Reprinted with permission from the CCEFP Newsletter, Issue 17, Winter 2012

The Real Value Of Hydraulic

Circuit Diagrams Like many readers of this Journal, I’m regularly involved in troubleshooting problems with hydraulic equipment. When in these situations, there are two things I always do before reaching for any of my diagnostic tools. The first is to conduct a visual inspection of the hydraulic system, checking all the obvious things that could cause the problem in question (always check the easy things first). The second is to request a circuit diagram.

There are four main types of diagrams that may be used to describe all or part of a hydraulic system: block, cutaway, pictorial, and graphical.

• Block Diagrams show the components of a circuit as blocks joined by lines, which indicate connections and/or interactions.

• Cutaway Diagrams show the internal construction of the components and flow paths. Because these diagrams typically use colors, shades, or patterns in the lines and passages, they are very effective at illustrating dif-

Circle 129

ferent flow and pressure conditions. This makes them ideal for training purposes.

• Pictorial Diagrams are often used to show a system’s piping arrangement. The components are seen externally and are usually in a close reproduction of their actual shapes in scaled sizes. This aids in component recognition and identification.

• Graphical Diagrams, a.k.a. schematics, are the shorthand system of the fluid power industry (Fig. 1). They comprise simple, geometric symbols, drawn to ANSI or ISO standards, that represent the components, their controls and connections.

Graphical diagrams are preferred for troubleshooting purposes. A graphical circuit diagram or schematic is a “road map” of the hydraulic system, and to a technician skilled in reading and interpreting them, is a valuable aid in identifying possible causes of a problem. And this can save a lot of time and money in a troubleshooting situation.

If a schematic diagram is not available, the technician must physically trace the hydraulic circuit and identify its components in order to isolate possible causes of the problem. This can be a time-consuming process, depending on the complexity of the system.

Worse still, if the circuit contains a valve manifold, the manifold may have to be removed and dismantled—just to establish what it’s supposed to do. Reason being, if the function of a component within a system is not known, it can be difficult to discount it as a possible cause of the problem. Schematic diagrams eliminate the need to reverse engineer the hydraulic system.

Where Are All The Hydraulic Circuit Diagrams?

As most experienced hydraulic technicians know, there’s usually a better than even chance that a schematic diagram will not be available for the machine they’ve been called in to troubleshoot. This is unlikely to bother the technician, though, because it is the machine owner who usually pays for its absence through prolonged service calls and increased downtime.

Where do all the hydraulic schematic diagrams go?

They get lost or misplaced, they don’t get transferred to the new owner when a used machine is traded, and in some cases, they may not be issued to the machine owner at all. Why? Because generally speaking, hydraulic equipment owners don’t place a lot of value on them.

So if you’re responsible for the maintenance of hydraulic equipment and you don’t have schematic diagrams for all your existing machines, try to obtain them before you need them. The nominal cost involved could save you a lot of money in the long run. In the case of a mass-produced machine, the hydraulic circuit diagram should be available from the equipment manufacturer on request.

If the machine is custom-built and the designer unknown, it may be necessary to have the circuit drawn from scratch. A fluid power engineer or your preferred hydraulics supplier could provide this service. When

procuring schematic diagrams, request both electronic (.dwg or .dxf preferably) and hard copy. Having an electronic copy makes it easier to update the drawing if the circuit is modified at any time. And always ensure that you are issued schematic diagrams for any additional hydraulic machines you acquire.

And if you design and build hydraulic machines, do your customers a big favor and make sure you give them an accurate schematic diagram with every machine they buy. While this may be viewed by some as making life easier for a competitor down the track, such narrow-minded thinking only serves to diminish the overall professionalism of our industry.

Fluid Power New Technology Focus

China-based SANY Heavy Industry Co. Ltd., a manufacturer of engineering machinery, is conducting a field test with a new fluid formulated with DYNAVIS速 technology developed by Evonik Oil Additives to validate performance in fuel savings and productivity improvements.

Fig. 1

Energy-Saving technology Offers Efficient Hydraulic Operation in Engineering Machinery

(Left) Fig. 2: Internal leakage of a monograde hydraulic fluid: hot, thin, hydraulic fluid backwashes through the vanes of a hydraulic pump, contrary to the direction of pumping.

This recirculation results in additional friction, which further heats the fluid, rendering it even thinner.

Fluids formulated with DYNAVIS® technology operate at higher temperatures with less internal leakage, maintaining equipment performance and saving fuel.

In Search of More Efficient Hydraulic Systems The hydraulic system is a key factor in determining fluid consumption in engineering machinery. Most motions are performed hydraulically with the power derived from a hydraulic pump. All pumps, however, are vulnerable to a power-sapping phenomenon known as "internal leakage," which occurs to a greater or lesser extent depending on working conditions. As hydraulic oils formulated with the DYNAVIS® technology reduce the loss of power in all temperature ranges, considerable fuel savings are possible (Fig. 1).

A hydraulic fluid will work optimally only within a defined temperature range. Simple “monograde” fluids are quite limited in their temperature operating range. As operating temperatures increase, their performance can weaken significantly, resulting in sluggish equipment performance.

In contrast, high-quality, multi-grade hydraulic fluids formulated with DYNAVIS® technology enjoy a broader temperature operating range and thereby improved equipment productivity and fuel efficiency.

At higher temperatures, hydraulic fluids formulated with the technology help reduce the pump's internal leakage, and the hydraulic fluid's ability to lubricate is retained. As a result, power output is higher, fuel consumption goes down, and the equipment is more responsive to operator controls. Even the normal wear and tear of seals and other hydraulic components is diminished.

Made for High Temperatures Long-working shifts for equipment running at high operating temperatures will cause monograde hydraulic fluids to gradually become thinner.

This results in internal leakage, a loss of efficiency as more and more thin heated oil backwashes through the pump vanes or pistons of the hydraulic pump, contrary to the intended pumping direction. Power is wasted as the pump keeps on running while the equipment response to the operator’s commands becomes sluggish and delayed. This unwanted recirculation also increases friction and further heats up already hot fluid (Fig. 2).

DYNAVIS® technology in fluid formulation reduces the loss of power due to internal leakage and puts the brakes on the resulting vicious cycle of hydraulic fluid becoming hot, thin, and then again hotter and thinner. The formulated fluids work to maintain the stability of power output of the hydraulic pump, even after many hours of work under maximum load. With better agility and performance, the equipment completes more load cycles and/or realizes fuel savings of 5% and above.

Fig. 3: Following the input of some basic data, the DYNAVIS® calculator estimates fuel savings, return on investment, and significant environmental benefits. Preliminary results from field tests have now validated these estimates.
