»MANY ARTICLES ABOUT certification focus on benefits to the individual, and I certainly don’t disagree with them. But I work for the International Fluid Power Society and look at it a little differently: What are certification’s benefits to an employer?
According to Phillip Barnhart’s 1997 Guide to National Professional Certification Programs, “Certifications are portable, since they do not depend on one company's definition of a certain job.” Certifications provide potential employers with “an impartial, third-party endorsement of an individual's professional knowledge and experience.”
For employers, certification is a screening tool that helps identify potential employees applying for jobs. Certification ensures that the candidate possesses at least base-level knowledge and skill.
that the company values their skills and knowledge. Another benefit to employers could be less turnover; satisfied employees usually don’t leave their employer. One concern expressed by some companies is a fear that if they train employees, those more highly valued professionals may leave to work somewhere else. There are many reasons to leave an employer, but I’ve never heard anyone say, “it was because they trained me too well.”
While trained individuals won’t necessarily increase production, they can help reduce downtime when faults in a system occur. Skilled professionals can quickly identify the fault’s cause and modify the system to ensure that it doesn’t reoccur.
Customers also benefit from well-trained and knowledgeable employees. They recognize that capable and credible professionals are serving them, and they see that a company holds its employees to the highest professional standards.
I obtained certification in 1990 because my boss at the Vickers Training Center decided that all instructors should be certified by IFPS, known at the time as the Fluid Power Society. My colleagues and I had been teaching for several years, but the explanation made sense: fluid power certification adds to our credibility, and it makes the training we offer relevant to the industry’s needs.
Some working professionals aren’t certified but possess the aptitude and attitude to obtain certification if they can get the right training. Employers should make certification a priority by providing the training employees require. Certification not only increases safety awareness, knowledge, and skills among employees, it yields benefits such as improved quality and increased productivity. Certification can result in less machine downtime.
Well-trained employees not only boost safety and productivity, they also improve engagement with the employer, as employees recognize
Companies benefit when they invest in their employees. When Vickers mandated that the sales force become certified, other manufacturers followed suit. Credentialing a sales rep as a Certified Fluid Power Specialist differentiates their company as better suited to design a hydraulic system. That doesn’t mean that noncertified professionals are not capable; many of them are. But certification assures customers that your company draws on an established foundational base of knowledge and skills.
As I reflect on my career in fluid power, I observe that my certification as a Certified Fluid Power Specialist opened many doors. It provided opportunities for professional growth that I would not have known otherwise. Over the years, I have known and worked with many of the industry’s great minds, and I am indebted to them for their mentorship and friendship.
Certification ensures that a job candidate possesses at least base-level knowledge and skill.
Employers should make certification a priority by providing the training employees require.

»THE ABOVE CIRCUIT drawing for a hydraulic press was upgraded after 10 years of continuous 24/7 operation. They replaced the main directional valve, added valve 3B unloading circuit, and installed a separate pilot pressure pump. This was all done to reduce the heat that was thought to be caused by the high flow through the directional valve when the cylinder retracted and omitted a 75 psi (0.5 MPa) back pressure check in the main pump line that supplied external pilot pressure to the valve.
The press was operational, but it still had the overheating problem that the upgrade was supposed to fix. They did find that the pilot line circuit was extremely hot going to the directional valve, and the line from check valve #2 to the tank was even hotter. The case drain line from the main pump to tank was warm like the original design.
What could be the problem?
See page 54 for the solution.

ARE WE THERE YET?
By Rance Herren, Founder, Fluid Power SME
charging electric vehicles. This is not an isolated incident domestically or globally, nor is it the only time extreme weather has affected EV drivers. It is well documented. Another concern is the availability of lithium, an essential element in rechargeable batteries.
The demand for lithium has increased at least 30 times between 2000 and 2015 and is expected to increase by another 1,000% by 2025 as compared to 2015. As of 2021, Australia accounts for 52% of global lithium production and was the number one lithium producing country in the world. Chile ranked second with its 24.5%, followed by China at 13.2%. Overall, Australia, Chile, and China have nearly 90% of lithium production in the world. The U.S. shares sixth spot with Portugal, having only 0.8% global share. The only existing lithium producer in the U.S. is in Nevada, and according to the U.S. Geological Survey, the country holds only an estimated 3.6% of global lithium reserves. China has the largest known lithium deposits in the world and will dominate the future lithium supply. Going forward, obtaining lithium may not be as easy given geopolitical concerns between China and the West. An inability to produce enough lithium would result in severe delays and disruptions to the roll out, implementation, and sustainability of electrification. Kind of rings of that whole dependence-on-foreign-oil-situation, doesn’t it? This is not to mention the environmental impact of lithium mining for batteries, the oppressively high cost to replace a battery, or the enormous cost and environmental impact of disposal. There are plenty of articles available to satisfy that curiosity should one care to know more.
So what does that have to do with fluid power systems used on industrial machinery and mobile equipment? More than one might think. From an electric grid perspective, battery-powered heavy construction, mining, and even agricultural equipment will be sharing and working in the same space as electric vehicles. That is unless diesel power generators are at hand. Yes, Rome was not built in a day, but many entities are moving full-speed ahead with their agendas, but with seemingly little attention being paid to the immediate and long-term impacts.
Among the many lessons from the COVID-19 pandemic we should have learned is how vulnerable our manufacturing base is to disruption. Another lesson is that supply chain is more than just manufactured products; it is about workers. Skilled workers. The fact is we are in a crisis. Let me say that again. We are in a crisis! Much like the hard sciences, the skilled trades are suffering an alarming drain on the talent pool. The number of individuals coming into and staying in the trades compared with those leaving or retiring is strikingly disproportionate. It has even become a matter of national security. In a September 2022 article in Foreign Affairs magazine, the authors argued, “Washington must acknowledge that education is no longer just a domestic policy issue but a national security issue on which the very future of the United States depends.” What this means is that as a country and a society, we need to put as much passion into educating those who will manufacture and maintain the equipment of the future as we do in developing and deploying the technology itself.
For the past several years, we’ve seen a regimented march to a steady drumbeat to abandon fluid power as a primary source of power transmission in many applications, and many are happy to see it relegated to a place where no other technology will suffice, regardless of efficiency, ease of application, and flexibility of installation. Many in our own industry are willing to cede the fight if they can cling to the power density argument. Unless the plan is to negotiate a peaceful surrender, it is time to ask ourselves some serious questions.
How well have we used the technologies and tools that we have available to us in the here and now? How many responsible for evaluating the various available technologies or designing fluid power systems are even aware of ISO/TR 22164, Application Notes for the Optimization of Energy Efficiency in Hydraulic Systems, or, for the pneumatically minded, ISO/TR 22165, Application Notes for the Improvement of the Energy Efficiency of Pneumatic Systems? These documents provide advice on how to design hydraulic and pneumatic systems with increased energy efficiency while maintaining the intended functionality of the machine. They are checklists of sorts to prompt the user of the many considerations for defining machine architecture, functionality, and duty cycle as well as component specification and selection, the use of software for system validation and optimization. This document does not tell one how to design a hydraulic or pneumatic system; rather it provides broad reminders of the technologies, tools, and best practices that are available to us right now.
Are we clinging to outdated technologies and rules of thumb from the past? Fluid power manufacturers are developing more energy efficient pumps, motor controls, and accessories. From energy efficient hydraulic fluids to variable frequency pump drives and electronics to manage power demands. How well are we embracing and adopting these technologies? Are reservoirs being grossly oversized based on antiquated rules of thumb or components being incorrect specified based on nominal flow rates? Are we really serious about STEM and skilled trades education for all trades, or just those that fit in the environmental box? Is skill-specific training and certification something worth investing in, or just another nuisance expense?
I will admit, I am not as hip and trendy as I would like to think I am. Somewhere I heard the phrase FOLO. Not knowing what it meant, I googled it. FOLO is an acronym for fear of losing out. It also turns out that FOLO has infested the business world too. Many leaders invest and prioritize their model based on hype, trends, and perceptions of what others are doing, rather than their own business strategy. They see a competitor going down a path, and they think they must do so too, often based on erroneous, incomplete, or biased data. They might not even fully understand or agree with what they are embarking on; nevertheless, they participate because everyone is doing it. There is also a lot of external pressure from nonfinancial factors, such as ESG – environmental, social, and governance – activism as part of their analysis and decision-making process. This is occurring posthaste, with equal intensity in consumer, commercial, and industrial markets.
None of this is to say that innovation, including electrification, is not important. But it would be ridiculous and disingenuous to claim we have made best use of all available fluid power technologies and best practices, and that, as a society, we have sufficiently invested in the infrastructure to support it. Please do not get me wrong: I do not hate electrification or any other form of alternative energy. It has many benefits that will ultimately outweigh the drawbacks, and fluid power must fight and earn the right to keep its place. But until we get where we want to go with electrification, maybe we pump the brakes a little, lest we go into an uncontrollable skid from which the industry may not recover.
We should all want to be good stewards of the planet we live on. But as noble as it may sound, at this juncture zero emissions means nothing more than transferring the source of pollution from one form of energy to another. And in many instances, we may be worse off than where we started.
Are we there yet? No. But we will be eventually. Maybe. •
Sometime ago, at CONEXPO-CON/AGG, it was possible to climb a stepladder, pass through a hatch, and sit next to the hydraulic brake motor of a large dump truck. However, just looking at the motor gives you less information about what is happening to the system than a diagnostic port.
In the last show, a vendor set up a stage with joysticks, gauges, and video screens for visitors to operate construction equipment several states away in real time. The conditions this equipment operates in could be the cold of the Arctic Circle to heat of the Sahara Desert. The equipment could be 5,000 feet under the ocean surface or in outer space. Note that the Colorado School of Mines now offers degrees in space resources (mining on asteroids). It is vital to know what is happening to the hydraulic components and fluids in this equipment. One way to do this is to extract a sample of the fluid or measure the fluid’s pressure and temperature. This article discusses the requirements of diagnostic gauge ports and explores available components to make life easier. MAIN Manufacturing Products has been putting gauge ports in flanges and making gauge port adapters for decades. MAIN has made flanges for over 65 years and participates in the SAE and ISO technical committees so we can speak of the market with confidence.
One of the first places to start is SAE J1298 Hydraulic System Diagnostic Port Sizes and Locations. This document was stabilized in 2016 by the SAE FCCTC subcommittee and is the consensus of fluid power manufacturers, OEM equipment manufacturers, and users. Stabilized means that the standard does not need regular review, as it is the best information currently available. It is not identical to ISO 8925 because SAE J1298 has additional metric and inch connections. SAE J1298 gives requirements for the manufacturers of self-propelled work machines and recommendations distilled from much discussion. Indoor equipment like presses and molding machines may not need the larger diameters of gauge ports specified, but the locational information in the standard still applies. It is a good idea to have a copy of the standard as it contains additional requirements. SAE J1298 covers only ports, not fittings, which have their own standards.
One of the first items to think about is what type of gauge port is needed. SAE J1298 requires M14 x 1.5 (ISO 6149), 3/8-18 (SAE J1926/ISO 11926 (SAE straight thread)), or SAE J518 flange ports for larger sizes. The “/” represents that SAE J1926 and ISO 11926 are generally technically identical. At MAIN, we see, in order of market preference:
MAIN manufactures flanges with gauge ports daily. The industry is trying to move to using elastomeric sealing specified in the SAE straight thread (SAE J1926) and ISO 6149. Metal-to-metal sealing, like the NPTF and some BSP threads, is discouraged because of its tendency to leak, although usage is very common.
Next is the size of the port. At MAIN, the 1/4 inch (#4) size is the most common, with 3/8 (#6) next. ISO 6149 ports are not common but MAIN does machine these in. The 9/16-18 thread corresponds to the #6 SAE straight thread size. SAE J1298 says for temperature, pressure, and sampling, the size should be the M14 X 1.5 ISO 6149 or the #6 SAE straight thread. It uses the larger size to improve fluid flow in colder situations. MAIN was involved with a distributor that was reconfiguring equipment that was transferred from oil fields in Alaska to oil fields in Saudi Arabia. When designing equipment, it is important to consider the life of the equipment and all possible environments in which the equipment could be used. Appropriately larger sized ports can also be used to measure flow. Ports should be located in places to get the most accurate readings. This is generally in the fluid stream. A requirement of SAE J1298 is to have at least one port at the main system relief valve. Other suggested places are the inlet and outlet ports of the following locations:
It is a good idea to consider the requirements of OSHA, or other nations’ equivalent organization, of assuring that the system is de-energized before working on it. Although gauges can malfunction or break, showing zero pressure on each side of a hydraulic component is a first step to assuring no hydraulic pressure in the component.
Finally, around the diagnostic port make sure that there is at least a 3 inches (75 mm) diameter and a 8 inches (200 mm) high area of no interference to allow for clearance for the connection to be made. This space allows the gauge or coupling to be installed. A type of fitting to consider is the push-to-connect under pressure fittings. These are hydraulic fittings designed to allow coupling and decoupling under pressure. With this fitting, gauge or sampling equipment does not have to be attached to the system at all times, or even most of the time. Many companies manufacture push-to-connect under pressure fittings, and they are available from many sources and can make the determination of location easier.
gauge port adapter plates discussed below, the reducing run tees are blocks with #12 or #16 SAE straight threads or other ports. They are regularly 2 inches or more thick. While the run of the tee can be made in any port style, most are straight threads, flanged (having a flange port), then NPTF.
Another convenient way to add a gauge port to hose or pipe with flange ports is with gauge port adapters. Gauge port adapters are plates between 1 and 1.5 inches
thick, ground on one side and O-ringed on the other. A gauge port is put in the side of the long way of the bolt pattern. Some manufacturers put an NPTF on one side and an SAE straight thread on the other side.
BOOTH #S84057
Gauge port adapters have the appropriate bolt pattern for the size of the flange. These parts get sandwiched in between the flange fitting and the component using longer screws. No machining is required and the port can be added very quickly in retrofit situations. The thickness of the plate is determined by the size of the gauge port. Many manufacturers offer these from stock in popular sizes and ports. MAIN has gauge port adapter plates stocked in all popular sizes, such as 1/4-inch and 3/8-inch NPTF, and #4 and #6 SAE straight thread. BSP (T or P) in 1/4 or 3/8 inch are manufactured regularly with very quick delivery times. The ISO 6149 ports are not as common in the U.S. MAIN has quick delivery times on them but many manufacturers and distributors do not stock them or have even offer the plates with ISO 6149 ports.
For system maintenance and troubleshooting, not all the systems have gauge ports where needed. The gauge port adapters lend themselves for use by maintenance workers and distributors trying to troubleshoot a system. They organize sets of adapters with longer screws and a gauge and putting this group into a pelican type case. When the troubleshooter arrives, they sandwich the gauge port adapters in-line with the gauge installed and get the information or sample they need to quickly and precisely analyze the system. •

Electronic control on hydraulic equipment has been exponentially increasing over the past two decades. Previously electronic control has primarily focused on increasing the fuel efficiency while maintaining the same level of performance. As machine controllers become more powerful and new sensor technologies emerge, the focus is now switching to operator efficiency. Automation has already become part of our daily lives by having thermostats that can automatically adjust the temperature and devices that can order supplies when low. This automation is expanding into hydraulic machines by simplifying repetitive tasks, assisting when navigating crowded work spaces, and helping less experienced operators
perform better and faster. This presentation will cover some of the latest technologies that are helping operators get more work done quicker and present what is coming in regard to fully automated machines.
2:15 – 3 p.m.
Presenter: Jon Jensen, SMC Corporation

Presenters: Andrea Vacca, Zifan Liu
This research demonstrates a novel design for an electrohydraulic unit made in collaboration between the Maha Fluid Power Research Center of Purdue University and Bosch Rexroth. In this unit, a permanent magnet (PM) electric motor with an internal gear pump are integrated in one housing, eliminating the shaft connection of traditional electric motor and hydraulic pump. When the unit is operating in pumping mode, the stator with electric windings is electrically inverted thus the rotor with permanent magnet is properly actuated and rotate at desired speed or torque). Therefore, the press-fit pump's ring gear is driven, causing the meshing pinion gear to rotate. That provides pressurized fluid to the actuators. For cooling of the stator windings, a small portion of fluid is circulated around the stator windings, through a cartridge orifice between hydraulic pump and electric motor chambers. This electro-hydraulic unit can also operate in motoring quadrant during braking and unloading of actuators for energy recuperation, improving system efficiency.

Fluid Power Forum Presents: Contamination Standards Prevent Machine Failure and Boost Cost Savings
Presenters: Barry Verdegan, Eric Lanke, Ivan Sheffield
Machine failures are costly. Contamination is the root cause of 80% of hydraulic failures, and 90% of these failures are preventable. Standards, such as those created by ISO or national standards bodies, establish a level playing field to allow manufacturers, suppliers, and users to speak a common language and use best practices to develop and implement contamination control programs. Standards developed by ISO
TC131/SC6 and other technical committees allow you to measure particulate contamination in fluids, set required cleanliness levels, choose appropriate filters for your application, compare products and identify false claims, and monitor the success of contamination control efforts. The speakers use real world examples to demonstrate the financial benefits of standard based contamination control programs. Brought to you by Fluid Power Forum, a podcast that features interesting and innovative applications of fluid power (hydraulics and pneumatics).

Cybersecurity
Presenter: John McDonald, TUV Rheinland
Smart devices have infiltrated every aspect of our lives, and equipment, vehicle, and manufacturing environments aren't exempt from the onslaught. Customers that used be worried only about price
and capabilities are now questioning manufacturers on the quality of the cybersecurity in their devices, since a single hacker can take control of a vehicle and run rampant, resulting in significant vulnerability for the manufacturer. The industry has started to address these issues with standards such as IEC 62443, but many manufacturers are just starting to wonder how they can implement a cybersecurity program. This session will review the relevant cybersecurity standards in this space, the elements you need to consider when implementing a product cybersecurity program and suggest an approach to help you get started.

Often fluid power is overlooked when it comes to machinery safety. This presentation will provide attendees with an understanding of the requirements for the control of hazardous energy using lockout, tagout, or alternative methods as they relate to fluid power. We will share the requirements from OSHA 29 CFR 1910.147 and ANSI/ASSP Z244.1 and the B11 series of standards for machinery safety.
Presenter: Dan Helgerson, Fluid Power Journal Technical Editor
While a great deal of effort is being made to produce more efficient compressors, pumps, and motors, there has not been enough attention given to providing more efficient systems. The new floating cup pumps developed by INNAS DV have overall efficiencies of better than 95%, but when dumping flow across a relief valve, the system is 100% inefficient. Efficient components do not guarantee an efficient system.
There are a number of reasons why a bladder or diaphragm in an accumulator typically fails.
The most common reason is that the compression ratio is exceeded. The compression ratio is determined by dividing the maximum system pressure by the precharge pressure. Typically, a compression ratio of less than 4:1 is acceptable for a bladder-type accumulator and 6:1 for a diaphragm accumulator. Maintaining a proper compression ratio is necessary to ensure that excessive flexing of the bladder or diaphragm doesn’t occur.
Another common failure is due to incorrect precharge pressure. It is necessary that the precharge pressure be less than the system minimum operating pressure. If the bladder-style accumulator was precharged to a higher pressure than manufacturer specifications, the bladder may fail. Under normal operation, the bladder is compressed in the shell by hydraulic oil and only expands to rest against the anti-extrusion poppet valve in the bottom of the accumulator when the system is off. Higher-than-specified precharge pressures can cause the bladder to pound against the poppet valve in the bottom of the accumulator when system pressure drops but is still within the operating range of the machine. This makes the bladder fail where it is pushed against the anti-extrusion poppet valve. Hydraulic fluid leaking into the gas side of an accumulator effectively reduces the working volume of the accumulator.
Another possible failure with rapid cycling that fully discharges the accumulator is that the bladder can get pinched under the poppet valve as shown in figure 1. This may also occur if the precharge occurs too rapidly.
High oil temperature may also cause the bladder or diaphragm to prematurely fail, as the polymers used in the construction of a bladder or diaphragm have reduced life expectancy at elevated temperatures. It is also important to understand that when precharging the bladder or diaphragm, it is necessary to perform this slowly, as rapidly expanding gas will cause the temperature to decrease rapidly and may subject the polymers to brittle fracture due to the extreme cold.
A leak in the bladder will cause the gas precharge to escape into the hydraulic system. This may result in a sponginess in the actuators. It can also allow hydraulic fluid to enter the bladder. A pinhole leak on the side of the bladder is difficult to diagnose. The bladder may effectively seal the hole when the hydraulic side pressure is low but expose the hole when the hydraulic pressure is increased and the gas compresses, moving the bladder away from the accumulator wall.
In a piston-style accumulator, the dynamic seal wear allows the gas to escape and permits hydraulic fluid to migrate into the gas chamber. As shown in figure 2, the hydraulic fluid in the gas chamber reduces the effective working volume of the accumulator. •
A higher-than-specified precharge pressure in a bladder-style accumulator:
a. is recommended so it doesn’t have to be checked as often.
b. can cause the bladder to be damaged by pounding against the poppet valve.
c. drops as the fluid heats up.
d. results in greater fluid storage during operation.
e. seals any pinhole leaks on the side of the bladder.
See page 54 for the solutions.
Forthousands of years, quarrying has supplied building materials, often carried out under arduous conditions far from home by simple, hard-working folk who measured daily output in baskets of rocks. Over the years, what was accomplished with a pickaxe and a shovel evolved into highly automated, mobile production lines that are thousands of times more productive than manual labor. Today, modern workers require rugged solutions that are simple to use and maintain, and in which problems are easily resolved by operators with minimum delay.
Crushing and screening in modern quarries involves crushing large pieces of material into smaller ones and sorting into similar-sized fragments. The starting material is typically freshly quarried or excavated rock or demolition material. Crushing machinery uses different crushing mechanisms, depending on the material. Where a considerable size reduction is required, the output of one crusher can feed a second one, and in some cases, a third may be necessary. Traditionally, material crushing has occurred in permanent locations where heavy-duty tipping trucks transport material to the plant. Recently, mobile crushing plant has proved practical and cost effective. Such equipment moves with wheels or caterpillar tracks to a convenient position. The same principles used in crushing and screening are now also applied to shredding, washing, and recycling machines that shred and sort waste for recycling.
The Webtec VFC Series of pressure compensated flow control valves ensure that actuator speeds remain virtually constant over all load conditions. When controlling the speed of a hydraulic motor powering a conveyor, for example, the motor rotates at the same speed, regardless of the amount of material on the conveyor belt. This ensures a consistent delivery position of the material. Once set, the weatherproof adjusting knob can be locked in position to avoid any inadvertent adjustment.
If a two-port flow control valve is used with a fixed displacement pump, then the excess pump flow has to pass across the system relief valve at full pressure. The excess pump flow is the flow the pump creates above the flow control valve’s setting. If the hydraulic motor (or other controlled actuator) is operating lightly loaded, then a large pressure difference across the flow control valve occurs. Flow passing across the relief valve and the large pressure drop across the flow control valve create inefficiency that results in heat.
When used with a pressure-limiting variable displacement pump, the pump flow rate automatically reduces to the rate determined by the flow control valve’s setting. But if the motor is lightly loaded, the pump outlet pressure remains at its maximum, i.e., the set pressure of the pump compensator. Since power in a hydraulic system is a product of flow multiplied by pressure, the output of a variable displacement pump only partially matches the power requirements of the actuator. Varying the pump displacement matches the flow requirement, but the pressure at the pump outlet can still be higher than what’s required by the actuator’s load. A lightly loaded actuator is still likely to cause a large pressure drop across the flow control valve, causing inefficiency and consequent heat generation. Two-port flow control valves are therefore best suited to variable pump systems in which the actuator only operates lightly loaded for short periods of its duty cycle. They can, of course, be used outside of these parameters by making provision for adequate fluid cooling.
A mobile crushing plant uses either an electromechanical or a hydraulic drive for the main crushing mechanism. Auxiliary functions are most often carried out by hydraulic cylinders and motors (actuators), which are ideally suited to operation in harsh working environments. Auxiliary functions on mobile crushers include track and conveyor drives, conveyor folding and positioning, and screen and deflector plate operation.
For over 40 years, Webtec has supported crushing-and-screening OEMs with rugged and reliable hydraulic valves that control the speed of actuators with varying loads, such as conveyor drive motors. The nature of the job means that motors can see rapidly varying loads, but ensuring that all machines work together requires continuous steady throughput. Machine designers, therefore, use pressure-compensated flow controls, including those made by Webtec, such as its conventional flow control valves, including three-port priority flow dividers and mono-block directional, flow, and pressure control valves.
A three-port flow control valve, also known as a priority flow divider, provides a pressure-compensated flow output from its priority port in a similar way to the two-port valve. So as before, this can be used to maintain a virtually constant speed of an actuator regardless of its load. Any excess flow directs to the valve’s bypass port. When used with a fixed displacement pump, therefore, the excess pump flow can be directed back to tank via the bypass port, rather than across the system relief valve. This means that the pump outlet pressure will only be slightly higher than the load pressure (typically 1-1.5 MPa [145-217 psi]) rather than the full relief valve pressure, thus reducing heat generation when the actuator is lightly loaded. So depending on the application, a simple, fixed displacement pump combined with a three-port flow control valve may be as efficient as a more complex and costly variable displacement pump and a two-port valve. U.S. research suggests that the average power transmission efficiency of current mobile hydraulic systems is around 21%. Both fuel prices and global emission targets demand improvement in that figure. An emphasis on control valve efficiencies is becoming increasingly important.
Rather than directing the bypass outlet flow to tank, it can also be used to power another function on the machine. In this case the priority port flow remains virtually constant, and the available bypass flow is the difference between the inlet and priority flows. In some applications this may negate the need for a dual pump to power both functions.
If remote speed adjustment is required, a proportional version of the priority flow divider enables an electronic signal to be used to vary the priority flow. All the necessary electronics are incorporated within the valve so it only requires an input signal that can be provided by a simple toggle or rocker switch to increase or decrease the priority flow setting. The hydraulic function of the valve is the same as for the manually adjusted version.
A priority flow divider can also be combined with a manually operated directional valve to enable the priority flow to be switched between two machine functions such as conveyor drives. A two-stage relief valve is also included to limit the maximum pressure in the priority outlet port. So the Webtec CV120 combination valve combines a single directional, flow, and pressure control in one compact, simple-to-install unit, with the opportunity for multiple valves to be connected in series using a high-pressure carry-over port. When connecting valves in series, a second pressure relief valve is incorporated in order to limit the carry-over port pressure. Combining functions in this way reduces both the cost and size of the installation by reducing the number of hoses and fittings required. Despite its compact design the CV120 combination valve doesn’t compromise on functionality, using the same pressure compensated flow control technology as used in the VFD range.
When the movement of two actuators needs to be synchronized, for example with track drives or conveyor positioning mechanisms, the FDC Series flow divider/combiner can be used to ensure equal flows to or from each actuator, irrespective of load. In one direction the flow dividing function will split the single flow input into two outputs, either equally or in a pre-defined ratio. In the opposite direction the two flow inputs will be combined into one, either equally or in the same predefined ratio as before. For cylinder applications, a levelling-up function may also be required to ensure that both cylinders fully reach their end strokes.
Certain functions on mobile crushers need to be interlocked to prevent dangerous or damaging situations. For example, operation of the track drive may need to be prevented unless a conveyor is moved to a transport position. The Webtec SV/DV 80 diverter valve can be used in such situations to prevent flow to a certain function unless mechanically actuated by the appropriate section of the machine.
For pumps and motors that operate for long periods of time, continuously monitoring their performance can provide an early warning of a potentially costly failure. Webtec’s new CTA flow monitor has been designed for this purpose and can be installed either in the pump outlet line to monitor pump flow rate or in the supply line to a conveyor motor for example.
For short-term tasks such as demolition work, where the task involved does not warrant the use of a dedicated machine, crushing attachments are often used that can be mounted onto an excavator boom and used to process smaller quantities of material.
By comparing the pump or motor flow rate with its rotational speed, a rapid assessment can be made of the component’s state of wear and action can be taken before a catastrophic failure occurs. A particularly useful feature of the CTA flow monitor is that its output can be observed remotely via a machine’s telematic system. For autonomous vehicles or machinery that is not constantly supervised by operators, a data link can be established via the cloud to provide an early warning of an impending component failure, thus saving the potential cost and time wastage of a catastrophic failure.
Webtec’s DHM Series hydraulic multimeter can be an invaluable tool for system troubleshooting and optimizing the setup of attachments such as crusher buckets. An integral part of the installation of this equipment is making sure the excavator is setup correctly for the bucket to do its work. If the excavator isn’t set properly, then the bucket won’t function to specification. The hydraulic multimeter enables the measurement of flow, pressure, peak pressure, temperature, hydraulic power, and pump volumetric efficiency. As part of a predictive maintenance program, measuring a pump’s volumetric efficiency by determining its loss of flow with increasing pressure is one of the best ways of assessing the pump’s condition. The in-built loading valve of the hydraulic multimeter means that this measurement can be simply carried out independently of the machine operation. The unit can then transfer data wirelessly for further analysis or the recording of performance history.
Also useful for system troubleshooting is the versatile HPM7000 Series portable data logger, which, by connecting to suitable sensors, can monitor such properties as pressure, flow, temperature, frequencies, speeds, and fluid contamination. This base model can be extended by the use of plug-in input modules to extend the number of CAN bus channels that can be monitored or for interfacing with analogue sensors using voltage or current outputs. The unit has a variety of different modes with the ability to data log 16 million measured values per test at a variable interval sample rate as short as 1ms and with a total possible storage size of 12GB.
Many leading OEMs in the crushing and screening industry have come to rely on Webtec’s wellproven products owing to their performance and reliability while operating under the harshest of conditions found in this industry. •
A total pump failure, for example, not only results in lost production while the pump is being replaced, it may require a considerable amount of time and effort to flush the system of contamination to avoid subsequent failures.
The RFS 200 flow hours counter is another new device used with a preventive maintenance program. Installed in the input or output line of critical hydraulic components, it monitors their actual usage time, thus enabling routine maintenance to take place when the component is approaching the end of its useful life. Compared to monitoring engine run time, the flow monitor can record individual component usage in applications where not all machine functions operate continuously.
Worksite safety – protecting operators and equipment from collision and damage – has always been a high priority for the off-highway industry. Whether at construction sites, agricultural fields, or road-building locations, keeping personnel safe from dangerous accidents and reducing machine damage from collisions has been the focus of many different kinds of efforts and investments.
Worker safety training and well-established, properly followed worksite safety procedures will always have an important role in these efforts. However, there is a significant opportunity for mobile machine builders to design features and capabilities into their machines that can enhance their safe operation.
To satisfy these goals, mobile machine builders are beginning to incorporate a range of new surround sensor technologies designed specifically to improve collision avoidance capabilities and enhance operator focus and situation awareness. This technology is being made available in modular, integrated platforms that include radar, ultrasonic, and camera components that can be software-integrated, making it easier for machine builders to integrate within their existing machine platforms.
Until recently, there had been limited investment by machine builders in the use of available surround sensing technology to improve the level of “situational awareness” crucial to improve jobsite safety. In agricultural applications, machine builders have been adding backup cameras to allow them to reverse a tractor more easily or combine and hitch to a piece of equipment.
In general the kinds of sensing technology now widely used in passenger and commercial on-road vehicles to provide driver alerts and collision avoidance capabilities have not been extensively exploited. This is, in part, due to the need to “ruggedize” these electronics for use in machines operating in more demanding environments and in equipment that typically generates higher levels of vibration that can rapidly degrade electronics.
The value of surround sensing is providing operators with a new array of sensory information about the risks and obstacles, both fixed and moving, that they could encounter operating their equipment. One
of the challenges associated with introducing vision systems, radar, and ultrasonics into mobile machines is the greater complexity of their operating environments, relative to commercial and passenger vehicles.
Compared to straightforward roads, driveways, and parking lots, risk conditions on a construction site or vegetable field can pop up randomly, which makes seeing the next risk more difficult.
The new surround sensing technologies need to be carefully selected and integrated into a given machine, based on that machine’s functions and the characteristics of its operating environment. So while each off-highway application is unique, there are three common principles that can be used to guide which types of sensory systems to use and how to integrate them into the machine.
Collision avoidance. Collision avoidance is the most easily recognized surround sensing capability. To varying degrees, cameras, ultrasonic sensors, and radar can all contribute to warning an operator of the imminent risk of collision and either alert them quickly enough to stop or change course, or automatically halt the vehicle.
Accomplishing some of these goals, including automatic stopping, will require integrating the surround sensing inputs into the overall vehicle operation; it may also call for more sophisticated controller hardware and software, as well as making sure that an off-highway vehicle’s CANbus network can support the added data from the sensors.
Focus on the job. Experienced equipment operators are typically well-trained in situational awareness. But it does demand, to a certain extent, that their attention be somewhat divided. A forklift operator pulling skids of material from shelves in a large warehouse has to simultaneously manage the skid removal task and constantly double-check that the backup space is safe and unimpeded.
Self-explanatory operator assistance. One of the advantages of this new generation of mobile machine sensors is that, combined with the more advanced controllers and software now routinely used on off-highway equipment, operators can be supplied with information that is literally self-explanatory. For example, video combined with ultrasonic sensors can be utilized with specialized operator cab displays to indicate which obstacles in the path of travel have a lower or higher risk of collision.
Leading technology suppliers like Bosch Rexroth are now offering these sensor portfolios in modular packages. They can also supply key insights into the right sensors, or combination of sensors, and will provide the greatest enhancement to operator safety and reduction of worksite accidents and collisions.
Each mobile machine, and the operating environment it is engineered for, presents unique working conditions and application requirements that can help determine the appropriate surround sensing technologies for a given application.
As noted earlier, camera systems are not yet widespread options for off-highway equipment. There is a new range of camera systems now available that have been adapted from passenger and commercial vehicles, and improved to provide long-term performance in the more demanding off-highway applications.
There are now multicamera systems that provide high-quality imaging with other features that make them a powerful tool to keep operators fully aware of surrounding conditions. After all, our strongest and most fast-acting sense is our vision.
These multicamera systems have high-resolution imaging of 1200 x 800 pixels. They also come with a specialized controller/CPU that provides best-in-class stitching together of the images, as well as zoom functions and the ability to add graphical overlays.
These more advanced features make multicamera systems, with their ability to provide a 360-degree view of conditions, a more effective tool for improving safety. The new systems take into account operating characteristics such as vehicle speed, steering angle, and drive direction to continuously stitch together a coherent image. They also feature detailed guidance on where to position the cameras on each vehicle’s exterior for the most effective coverage.
Ultrasonics can provide highly valuable short-range operating conditions. These sensors have been adapted from the latest generation of automotive sensors, with configurations that can range from one to 12 sensors, depending on the size of the machine and its typical operating environment.
The software has been created to achieve measurement rates of up to 120 milliseconds. In the kinds of sensors now available, ultrasonics provide an accurate description of static or moving objects and obstacles as close as 15 centimeters to 5 meters away, depending on the signal resolution.
Applications in which ultrasonics makes the most sense are those with tighter operating environments and many static and moving obstacles, like skid steer loaders on construction sites. A key aspect to assess of these ultrasonic platforms is how they generate and process signals from multiple sensors.
Some systems will actuate all the ultrasonic sensors at the same time. But this runs the risk of generating false positives or negatives and other noise that can impact the quality of the sensing. More advanced systems trigger the sensors in precisely controlled sequences and process the ultrasonic echoes rapidly to capture a much more accurate portrait of the surrounding system.
In some more advanced applications, the ultrasonic data can be overlaid on the 360-degree video inputs, with colored graphics indicating which obstacles are closer and of higher risk.
While ultrasonics can provide obstacle data from close-at-hand objects, there is a significant role that radar can supply for situational awareness and surround sensing. Radar is most useful for detecting objects farther off than ultrasonics, and it can detect risks while a vehicle is in rapid movement.
There is a wide range of construction and agricultural equipment that also has to travel significant distances on roads at speeds up to 40 kilometers per hour. Radar-based collision avoidance systems offer the highest degree of safety for these vehicles when they need to operate on the roads.
The radar systems being offered by leading suppliers feature both near- and far-range integrated antennas and ground-detection filters, and can detect and track up to 40 objects simultaneously.
Since each mobile machine has unique operating characteristics, there may not be a need to have all three kinds of surround sensing technology – cameras, ultrasonics, and radar – incorporated into one piece of equipment. However, many widely used machines could benefit from all three.
Wheel loaders used on construction sites often drive at high speeds from one part of a site to another or to another. At the same time, a wheel loader’s work often involves them in tight situations where ultrasonics play a more valuable role.
And in these wheel loaders, the operator cab is typically mounted high on the machine because the operator needs a 360-degree view of the surroundings. Additional multicamera displays augment the view. Combined with the potential for graphic overlays of the ultrasonic sensors, their ability to focus on the job and have self-explanatory data on risks can improve safety and reduce the risk of accident.
To make the best use of this technology, mobile machine builders who consider the potential advantages of the new generation of surround sensors will need to assess how to modify the design and engineering of their systems.
First they’ll need an intelligent assessment of which of sensor packages make the most effective contribution to safety, based on a machine’s dimensions, operating conditions, and demands on the operator.
Machine designs may need to be modified with expert guidance. Mounting brackets and wiring harnesses must be carefully selected, with particular care about exactly where cameras or ultrasonic sensors are placed to provide the most effective system performance.
Modifications to HMI displays may also be needed so video can be easily integrated. There will also need to be an assessment of controller capabilities and communications backbone. In the case of high-quality video, Ethernet-based connectivity may be needed on the machine.
The right high-performance surround sensing technology offers the potential to significantly enhance safety on the jobsite and out in the field. It can reduce operator stress with assistance systems that make it easier to keep them situationally aware of risks around them.
The systems have now been optimized and ruggedized for the off-highway machine environment, offering a new suite of tools to improve safety, reduce the risk of accidents and equipment damage and ultimately help off-highway operations run more smoothly. •
