How Technology Will Help Global Agriculture Feed A Hungry World

W

e will need to increase agricultural production 100% by 2050 just to feed the growing population of developing countries. That may sound a bit worrisome, but 2050 is a long way off, so it will be someone else’s problem. Right?

Well, in just 15 years, it’s possible that 9 billion people will go to bed each night either hungry or well-fed depending largely on how well the global agriculture industry responds to the unprecedented challenges it faces today.

Both facts are consequences of the same three simple drivers: 1. Land. As Will Rogers said, nobody is making any more of it. There is only so much arable land, we know where it is, and we’re using most of it today.

2. People. Our population is globally growing.

Growth is accelerating, and many are going to be comparatively affluent urban dwellers with a taste for meat, dairy, eggs, and other forms of animal proteins.

3. Consumption Patterns. Moreover, crops aren’t just for feeding people anymore. Biofuels are another megatrend that will impact the use of plants as a primary human food source, but not the only one by a long shot.

If you put those three drivers together, you inevitably arrive at two fundamental conclusions: *Farmers everywhere are going to have to become a whole lot more productive. *They won’t be able to do it without a lot of help from innovative new technologies.

Meeting these challenges will require farmers across the globe to become more productive. Everything from tractors, combines, and planters to all of the specialized equipment that supports dairy and livestock operations, orchards, vineyards, and the production of vegetables will have to be re-examined, re-purposed, and re-designed to make them more efficient.

Many of the solutions will be familiar because they are extensions of technologies we use today. Genetically modified plants and animals, computers, wireless communication, global positioning systems, clean diesel power, autonomous vehicles, precision agriculture, robotics—and, of course, hydraulics.

Hydraulics—and especially the marriage of hydraulics and electronics we call electrohydraulics—will play a key role in many solutions. Electrohydraulic technology combines the power density of hydraulics with the intelligence of electronics to deliver real muscle in a small, efficient package with

the kind of control that used to be available only from electric servos.

Put that together with a GPS receiver and onboard computer on a tractor, and you have something that can minimize the inputs of time, fuel, fertilizer, and everything else required to produce a crop. With a human being driving the tractor, a significant portion of the inputs applied to a field are wasted because a person just can’t make perfectly touching passes hour after hour, day after day.

But with electrohydraulics doing the heavy lifting, a tractor guided by GPS technology can. In a world that needs more food from less land every year, that’s very big news.

The same sort of intelligent systems can improve the efficiency of animal-feeding systems, orchards, and vegetable-growing operations. Electrohydraulics is equally applicable to irrigation valves, gates, sprayers, and other equipment. The days of simply dumping water on the ground and hoping for the best are over.

It all boils down to doing more with less through the efficient, intelligent management of power, something for which electrohydraulics is very well suited.

And make no mistake; doing more with less is the name of the game in agriculture from here on out.

Quick Check of Accumulator Precharge Watch the gauge showing pressure at the hydraulic side of the accumulator. Start the pump.

The gauge will "jump" to the accumulator precharge pressure then slowly climb to full system pressure.

Again, watch the gauge. When the pump is powered down, the accumulator precharge will slowly bleed off until the precharge pressure is reached then "drop" to zero.

This is not an accurate check of the precharge, but instead only a quick method to determine the precharge is about where it should be. There are several assumptions here: the gauge is showing accumulator pressure on the hydraulic side, there is a restriction to control the discharge rate at shutdown, and the system is designed to discharge the accumulator at shutdown.

Monitor Equipment Performance PLCs with PID loops can often be used to monitor equipment performance, sometimes even without adding dedicated sensors. For example, consider a simple hydraulic press where each cylinder is equipped with an LDT and is actuated by a proportional flow control valve with voice coil actuator and integral pressure transducer. The signals from the LDTs and pressure transducers coincide to input to the PLC PID, and the output from the PLC manipulates the valves.

Many modern PLCs offer data-logging capabilities that would allow us to review trends in the control signals for analysis, as well as the PID loop error signals, without adding additional, dedicated sensors. As seals wear out and leakage accumulates, these control signal quantities will increase over time. If we added a case drain flow meter input to the PLC, we could also monitor pump efficiency trends.

Not every hydraulic press application is suitable for this sort of integration; however, many products and processes do benefit from the precision controls and proactive maintenance that are made practical by these technologies.

Fluid Power Case Study

Reducing Hydraulic Noise:

An Elephant’s Tale

ecently some new tenants arrived at Reid Park Zoo in Tucson, Ariz.—a group of elephants from the San Diego Safari Park. When zoo consultants A thru Z Consulting and Distributing built a new addition for the elephants at their new home, they wanted to make it as animalfriendly as possible. One of their objectives was to reduce the noise of the hydraulically controlled gates on the elephant holding areas, which are used when these animals are transferred between their holding areas to the exhibits and back again.

Why is this important? When the gates open and close, the elephants (and visitors) could hear the pump working, which was causing anxiety in the elephants. Because the elephants were still adjusting to their new environment, it was creating a potentially dangerous situation for their handlers. After installation of the Wilkes & McLean WM-3138-16 suppressor on the FluiDyne piston pump, the noise was virtually eliminated. The 25-hp pump is providing 33 gpm at 1,400 psi through one-inch lines.

The visitors of the zoo also appreciate the reduction of hydraulic noise as Reid Park Zoo is known for its relaxed, natural setting that offers a welcome escape from the hustle and bustle of the surrounding city.

Bill Shields of OTP Cleveland guided the sales and implementation of the HPU system and Wilkes and McLean suppressor. John Balliett of Fluid Systems Service in Cleveland coordinated the design of the motor, pump, suppressor, and accessories for the zoo application.

he purpose of an assessment of an existing compressed air system or the design of a new one is to establish sustainable best practices for maximizing the reliability and performance of the system and to minimize life-cycle costs. The desired outcome is to reduce operating costs, product contamination and scrap, and the possibility of environmental damage from the risk of poorly designed systems.

Any new design or recommended improvement should provide direction for the design, installation, operation, and maintenance of compressed air systems. Energy costs alone will generally exceed the purchase price of a compressor in the first year of operation.

Less than 20% of the input power to the electric motor is converted to compressed air, and the balance is rejected as heat. Often the highest savings are achieved by addressing the inappropriate application of compressed air and the proper control of the compressed air system.

Compressed air plays a critical role in a very high percentage of industrial applications. Minimum compressed air pressure and quality levels must be established and maintained for specific uses.

Obviously, breathing air requires higher quality than compressed air for most packaging operations.

Are there guidelines for use by project managers, facility managers, technicians, and consulting engineers who design, specify, or operate compressed air systems? Will new systems require a different approach than a proposed expansion?

Defining the Requirements – What’s the Use? Each industry is different, and each plant within any given industry is unique. A new plant will have specific initial requirements, but these will change over time, and anticipated growth should be considered in the initial design.

• Identify and tabulate anticipated end-uses and quantify pressure, rate of flow, compressed air requirements, and air quality.

• Machinery and processes requiring compressed air should be identified by type and the manufacturer’s specified requirements for pressure and flow.

• Plant air for general use also should be identified, quantified, and possibly considered as a separate system from process.

Breathing air requires special considerations.

End-Uses – How Much Air is Needed?

Industry end-uses and compressed air requirements should be quantified. Using manufacturers’ specifications, begin with a “demand profile,” which is a form to list each steady demand, including the required pressure and operating flow rates at minimum, average, and peak conditions. Identify and separately list all intermittent demands with compressed air “on/off” cycle times in seconds or minutes.

Include the number of shifts and resulting variations and potential future additions.

The type and size of compressor required and the quality of the air necessary for the applications are very important factors. The air quality requirement for the applications must be considered

as part of the selection of the compressors and the air treatment. An oil-free air compressor may be the specific process or plant standard. Some plants, however, have successfully installed lubricated compressors with proper filtration and excellent maintenance to provide oil-free air. In other cases, plants with almost equal requirements for oil-free air and a tolerance for an acceptable level of lubricant have two separate systems. ISO standards classify the level of particulates, degree of dryness, and amount of lubricant in the air.

Operating at the lowest possible system pressure allows for the most efficient operation. For example, in many compressors, lowering the compressor discharge pressure by 10 psi can reduce specific power (cfm/kW or kW/100 ft3) by 5%.

Many plants supply compressed air to the main distribution system at a pressure that is 5-psi above the required minimum, which is determined by either the most significant uses or the one most sensitive to lower pressure.

Fig. 1 shows that leaks are typically 10-20% of total demand. Original recommendations were to maintain the leakage rate below 10%; however, compressed air has been recognized as a very expensive utility, and many plants have a standard stating that “leaks should be maintained at less than 5% of peak flow.”

• Artificial demand: increased air consumption required by any unregulated uses due to system pressure in excess of what is actually required.

• “Potentially” inappropriate uses: any application that can be done more effectively, or more efficiently, by a method other than compressed air.

• Leaks: an unintended loss of compressed air to the ambient.

A corollary is to provide automated equipment to shut off air to applications when not in use.

A few end-uses requiring higher pressure can result in the entire system pressure being maintained at an “artificially” elevated level, producing an increased energy consumption. In some plants, end-uses were modified to operate at a lower pressure.

In other cases, a motor-driven booster was used for continuous demands or an air amplifier for intermittent uses at higher pressures.

Determining the minimum practical pressure required for an application has brought about the use of low-pressure blowers rather than system-compressed air.

There are many examples in plants where a "sparging" process, using compressed air for aerating or agitating liquid, has been replaced with an industrial blower.

Depending on the height of column and specific gravity of the liquid, the discharge of the blower was designed to be 4 psig to 15 psig. Assuming 15-psig blower discharge pressure, the energy saved is approximately 60%. In these applications, attention was devoted to determining the possibility of any adverse effects on the process and also the changes to the distribution piping.

Air motors can often be replaced with electric motors, reducing energy consumption by 80%. Similarly, where applicable, replace double-diaphragm pumps with electric motor-driven pumps.

Applying a vacuum pump for continuous-demand applications rather than creating the vacuum with compressed air-venturi methods has been very successful in many industrial applications.

The Quality of Compressed Air Clean, dry air is defined by the application in which it is used; therefore, compressed air requirements in various industries and laboratories will significantly vary. For most industrial applications, ISO 8573.1:2009 is the international standard for compressed air quality and defines the level of contamination permissible in compressed air (Table 1). The standard identifies three primary forms of contamination in industrial compressed air systems: solid particles, water (vapor), and oil. Contaminants are classified and assigned a quality level, ranging from class 1 (recently class 0), the highest purity level, to class 9.

There are also possible gaseous contaminants. The acceptable level depends on the application, and the purification methods will depend on the specific requirements. It is very important for compressed air users to be aware of what is considered a potential contaminant in their applications, the effects of these contaminants, and the methods to achieve successful and sustainable contamination control.

Process and Laboratory Air Process air is sometimes defined as air that comes in contact with the product or has incidental product contact. Compressed air must meet minimum requirements of the process equipment that it serves. A minimum pressure dew point of 35ºF to 39ºF supplied by a refrigerated air dryer may not always be suitable. A regenerative desiccant dryer to provide a substantially lower dew point may be necessary, but will consume more energy. Additional filtration may be required depending on the requirements of the air consumer. The additional filters can be located centrally at the compressor or at points of use.

Packaging and Instrument Quality Air Depending on the end product, packaging air in most plants is defined as air that is used in packaging lines that does not come in contact with the product in any way.

Instrument air is defined as air that is used for instrumentation and controls. Most instrumentation engineers specify oil-free air compressors. Some specifications state that “the compressed air supply shall be oil-free”; this may often be achieved with proper filtration. The pressure dew point of compressed air used within the plant should be at least 18ºF below the factory’s minimum temperature. For instruments used outside the plant, the pressure dew point should be at least 18ºF below the lowest ambient temperatures to which any part of the instrument air is exposed. To monitor these dew points, an alarm is installed to alert operators of a possible problem.

Where instrument, process, and packaging air are all required from one system, use the highest-quality air required for the system. In many process plants, two systems have been designed: one for "plant" air, which may not be dried, and one that is generally at a much higher quality for instrument air or some processes.

Because of its importance to control processes, many plants will use dry nitrogen as a backup to support the instrument air system. This is especially important when short-duration power interruptions occur and minimum pressures must be maintained for all instruments and valve actuators.

Breathing Air In industrial plants, air may be supplied to respirators, hoods, and helmets for various applications, and special breathing air systems are installed. Occupational Safety and Heath Administration (OSHA) standard OSHA: 1910:13d applies and requires drying, filtration, and treatment to meet specific levels, including carbon monoxide, with an alarm system.

The Compressed Gas Association (CGA) Standard Commodity Specification G-7.1, Grade D commonly is specified for plant breathing-air systems.

A minimum requirement shall conform to USA OSHA standard 1910.134 (revision effective April 1998). The CSA (Canadian Standards Association) standard CAN3-Z180.1-M85 is also listed.

Check to ensure compliance with all local standards.

• Compressed Breathing Air shall meet at least the requirements for Type 1 – Grade D breathing air as described in ANSI Compressed Gas Association Commodity Specification for Air ANSI/ CGA-G7.1. The OSHA standard references this specification and is essentially consistent with ANSI. • Breathing air must also be tested for additional contaminants such as methane, nitrogen oxide, nitrous oxide, halogenated hydrocarbons, and other hydrocarbons. Air that is grossly contaminated or oxygen deficient may lack the ability to be purified to levels that are acceptable for breathing.

location, such as outdoors or from conditioned plant air, increase the intake pipe one size per every ten feet of length. Do not install compressed inlet piping near cooling tower or exhaust fan discharge, as this could contaminate the inlet air to the compressor. Install an inlet vacuum gauge to monitor the condition of the intake filter if one is not supplied within the compressor.

Adequate compressor room ventilation is essential for heat rejection, but it is not usually cost effective to air-condition the air compressor area. If the compressor ventilation air is ducted out of the compressor room, the total static pressure of the combined inlet and outlet ductwork generally should not exceed 0.12 inches (30.5 cm) of H2O. A ventilation fan installed in the ducting may be required for heat recovery or to address large ducting losses.

Environmental Design Considerations — Air Quality The inlet air to the compressor should be as cool, dry, and as clean as possible.

Clean is defined as a minimum amount of dust and foreign matter. The air cannot contain other contaminating gases such as ammonia, chlorine, sulfur, carbon monoxide, etc., which can affect the compressor, piping processes, and pneumatic system components. Compressed air must be free of corrosive contaminants and hazardous gases.

For lubricant-free positive-displacement-type compressors (screw and reciprocating), lowering the inlet air temperature by 5ºF will improve compressor performance approximately 1%. Where practical, outside air should be considered for many applications. If the inlet compressed air piping is taken from a remote

of compressors and ancillary equipment. The data forms could include the following information: package power (kW), pressure, flow (cfm), inlet conditions, dew point for dryers, cooling water or ventilating requirements, service life, and maintenance requirements.

Optimization and Control Strategies The objective of an effective automatic system control strategy is to match system demand with compressors operated at or near their maximum efficiency levels. The result should be to operate compressors at the lowest possible input power and total energy consumption for all demand conditions. Excessive partload or no-load operation is wasteful and should be avoided where practical.

Variable speed compressor controls are available to minimize wasteful part-load and inefficient operation.

Some examples of multiple compressor sequencing are cascading systems and rate-of-change systems. A cascading system overlaps the pressure setting in the compressors installed so that as the pressure increases or decreases, the appropriate compressor is started or stopped, loaded or unloaded. This type of system generally requires a large pressure band and considerable storage volume.

Today, modern multiple-compressor systems can benefit from sophisticated controls like Smart Sequencers to efficiently match compressor operation and air delivery to the system requirements at the lowest energy consumption. This type of sequencer can be used with any combination of compressor type and manufacturer.

Reducing compressor discharge pressure by 2 psi will reduce input power by 1% for many types of compressors. Proper sequencing controls should consider fluctuations in demand, available storage, and the characteristics of the equipment supplying and treating the compressed air.

Effective control strategies require documented data to monitor: • Flow measurement (CFM) using mass flow meters that compensate for pressure and temperature variables • Power and energy consumption, kW and kWh • Pressure and pressure drop (∆P) before and after major components such as dryers, filters, etc.

• Temperatures. These are often supplied with the equipment.

• Pressure dew point of the system Another optimization strategy is pressure/flow controllers. A pressure/flow controller is a device that serves to separate the supply side of a compressor system from the demand side of a compressed air distribution system. This controller maintains a constant demand-side pressure with varying demand loads. For this controller to be installed in a system, the supply-side pressure is generally higher (minimum 10 psi) than the demand-side requirement for the controller to work properly. This requires the compressors to operate at an elevated pressure and increase horsepower, but pressure on the demand side can be maintained at a lower stable level to minimize actual compressed air consumption.

Storage, sized to meet anticipated fluctuations in demand, is an essential part of the control strategy. Pressure/flow controllers are an optional system and may not be applicable in many cases. Each compressed air system differs in supply, distribution, and demand aspects that require proper evaluation of the benefits to the system of a pressure/flow controller. Additional primary and secondary air receivers may often be used as an alternative to, or in conjunction with, pressure/flow controllers. Compressed air is a very expensive utility, and the system must be managed to reduce costs.

The electric motor, or any prime mover, inputs power into the compressor shaft, and through the compression process, heat is developed in the air stream.

Heat and work are two different methods of transferring energy. It is possible to extract, by heat transfer, an amount of energy from the compressed air that is equivalent to the amount of energy that the electric motor placed into the compressed air. It may be possible to recover almost all the heat generated by the air compressors to significantly reduce a plant’s total energy consumption.

The same strategies and techniques to optimize the operation of the compressed air system can be applied to both new and existing plants. It begins and continues with analyzing the demands.

Company Profile

Panagon Systems

T

he global hydraulic requirements for industrial and mobile applications are immense. The United States is currently the largest GDP country in the world, and due to massive industrialization, most of the hydraulic product usage is here. Industrial growth depends on maintaining a high degree of productivity, and better productivity usually decreases the end product price.

Achieving the highest productivity requires industrial machinery and mobile equipment to operate at its maximum intended purpose for the longest period of time. This requires regular preventative maintenance of the mechanical and hydraulic systems to prevent breakdowns and loss. Regardless of how well the product is made or maintained, at some point a mechanical or hydraulic system failure can occur. When equipment is not regularly maintained, it causes unexpected failures that always seem to happen when the equipment is needed the most. When that happens, replacement parts are quickly required.

Panagon Systems plays a role in providing hydraulic replacement pumps, motors, and transmissions for various applications. Based in Macomb, Mich., this manufacturer of aftermarket hydraulic piston pumps and parts provides a large variety of current and obsolete components. The company has the ability to produce a product from the raw materials to a finished pump, assembled, tested, painted, and shipped from its facility.

Over the last 50 years, fluid power applications have become necessary for various machines

18

July/august 2012

and equipment. Fluid power systems have been widely used from circus Ferris wheels to NASA space applications. Each one of these systems is ultimately equipped with various pumps, valves, motors, and other accessories. Failure of any one of the hydraulic products can put a piece of equipment into breakdown, causing a monumental loss in productivity. A specific machine breakdown somewhere can cause a shock wave of idle machines or equipment somewhere else. In reality, a breakdown could be felt internationally. There are literally thousands of piston pumps and motors from different manufacturers that are in the field providing power to every conceivable hydraulic system in every global industry. If one of these crucial pieces of machinery or equipment breaks down due to a faulty hydraulic pump, there is sometimes no quick replacement answer. Panagon rescues the broken-down machine or the system by supplying the specific piston pump or motor, therefore reducing the machinery downtime and helping to restore the industrial productivity.

Original product manufacturers occasionally phase out certain product lines based on application needs, customer demands, and just a general need to keep pace with the worldwide competition on product variety. When this happens, there remains a

huge amount of machines and equipment still in operation with these phased-out hydraulic products, which need to be serviced for many years to come.

Most OEM manufacturers can support a breakdown situation through their distributor networks for their current production product lines, but due to phasing out of their old products, the customer soon finds out the parts are not available, or if they are, the delivery time could be months or the cost is sky high because it has to be produced out of the normal production schedule. Under those circumstances, the customers are sometimes required to look at other suppliers for the replacement parts. Panagon Systems attempts to fill this void by manufacturing the phased-out, expensive, and unavailable pumps, motors, and transmissions.

Founded by Karl Toth nearly 25 years ago, Panagon Systems has remained a low-profile organization producing hydraulic parts on demand. The company has expanded manufacturing capabilities in China to support the needs for the Asian, Asian Pacific, and Middle Eastern hydraulic user markets. The goal is to make sure that the pumps, motors, and parts produced meet or exceed the original component specification in every way so the end machinery efficiency remains the same and everything is completely interchangeable. In 2009, the company won a Best of Business award, which recognizes the top 5% of small businesses throughout the country, in the hydraulic systems and equipment category. The selection committee chooses the award winners from using statistical research, consumer feedback, monthly surveys, a review of consumer rankings, and other consumer reports.

From a humble beginning, Panagon Systems has moved into a unique category of manufacturers that can support the industries dependent on fluid power.

PIRTEK Sky Harbor, Phoenix, Ariz., owned by Stewart Bartlett, received a job from Case Foundation Company with a short lead-time on a 28-metric-ton drill rig. Case Foundation Company, a full-service and deep foundation specialist, focuses on drill shaft foundations for major projects such as highways, bridges, and airports.

Before sending the drill to the next job site, there was a need for some quick hose work. The drill was scheduled to go to another job in one week, just before the New Year’s holiday.

The drill had many large hoses that needed replaced, and a large amount of 6,000-psi, 1.5" hose, and metric fittings were needed. PIRTEK corporate headquarters in Rockledge, Fla., and PIRTEK Madison Heights, owned by Eli Dorfman in Detroit, Mich., supplied all the required hose. Tony Stevens, PIRTEK Sky Harbor mobile service and sales technician, worked with Case employees to identify, rebuild, and replace the hoses on the drill. He assembled 16 hoses ranging from 6-ft. to 24-ft. in length and two 20-ft. steel lines. The job was completed ahead of schedule.

NFPA – National Fluid Power Association

NFPA Membership is the Right Choice for Fluid Power Distributors

N

FPA is committed to its mission to serve as a forum for all fluid power channel partners, and as a result, NFPA distributor members now have the right to be full voting members of the Association. As of July 1, 2011, distributor members are eligible to serve on the NFPA Board of Directors and the NFPA Executive Committee. NFPA believes that this is the path to strengthening the fluid power industry and its members’ successes.

Using NFPA services, such as the product and distributor locator, member directory, and distributor council, and displaying the NFPA logo on all company materials, have given distributor members a powerful opportunity to gain visibility for their companies, bringing more customers to their doorsteps.

NFPA activities, such as the acclaimed Industry and Economic Outlook Conference, the members-only annual conference, two free regional meetings each year (Chicago and Detroit), and IFPE (the premier fluid power show in North America), have created new and exciting connections to people, resources, and business opportunities.

NFPA’s membership also brings a large menu of fluid power market information to its distributor members: • Monthly confidential shipment statistics summary • Annual current industrial report • Quarterly market outlook report • Free quarterly economic update Webinars featuring noted economists To learn more about the NFPA distributor membership, contact Leslie Miller, NFPA’s membership manager, at 414-778-3369 or lmiller@nfpa.com.

Experts from the offshore energy industry around the world came together April 30 to May 3 for the 2012 Offshore Technology Conference at Reliant Park in Houston, Tex. Attendance at the conference reached a 30-year high of 89,400, the third highest in show history and up 14% from last year.

Attendance surpassed the 2011 total of 78,645, and the sold-out exhibition was the largest in event history at 641,350 ft² with the addition of the outdoor pavilion, up from 603,000 ft² in 2011. The

exhibition had 2,500 companies representing 46 countries, including 200 new exhibitors that included exhibitors from Bahrain, Hungary, Israel, Lithuania, New Zealand, and Taiwan.

“OTC 2012 was the most successful event we have had since the early 1980s,” said Steve Balint, chairman of OTC. “In terms of strength of the technical sessions and technology on display, OTC reached a record-breaking number of people and offered the most ways to connect, educate, and conduct business.

The industry is on the rise and challenges are ahead, making it more important than ever to collaborate and share best practices with colleagues all over the world. OTC is the place to do that.”

This year’s event featured eight panel sessions, 29 executive keynote presentations at luncheons and breakfasts, and 300 technical papers. Speakers from major, independent, and national operators; global government officials; and academia presented their views on the current challenges and future directions of the industry.

Technology is always at the forefront of OTC and was evident by the 13 technologies winning OTC Spotlight on New Technology awards. The recipients were recognized for innovation in allowing the industry to produce offshore resources.

OTC also introduced new technical topics and ways to connect through two focused networking events-one on health, safety, and environment professionals and the other on women working in the industry.

“Our objective was to bring women together to hear from several inspirational leaders, discuss our experiences in the industry, and collect feedback on how OTC and our member societies can help support women in the industry,” said Cindy Yeilding, a member of the OTC Board of Directors.

Attendees in both sessions may continue the conversation on LinkedIn subgroups under the Offshore Technology Conference 2012 group.

The annual dinner was attended by approximately 900 industry leaders and conference attendees, and raised $225,000 for Engineers Without Borders USA.

Because if there's ONE, single hydraulics skill, above all others, you can take to the bank, that skill is: TROUBLESHOOTING. That’s right, the hot-shot troubleshooter, the man who can cast his eye over a hydraulic system and quickly zero-in on the fault, without breaking sweat, is 'Top-Gun' in the hydraulics world.

He's a soldier of fortune. Admired by some; envied by many.

And the good news is, it's just become a LOT easier to join the ranks of this elite and highly sought after group of hydraulics professionals.

The Definitive Guide to Hydraulic Troubleshooting is a NEW, training program developed by regular FPJ columnist Brendan Casey, which is focussed entirely on the skill of troubleshooting (it is a skill all on its own; and a skill ANYONE can master).

Vacuum

Measurement:

A Basic Guide

T

here is often much confusion with regards to the units used to measure the level of vacuum being generated in an industrial application. This article explains which ones are the most common, their origins, when one should be used instead of another, and how to convert between them.

The most common unit of vacuum measurement used in North America for general vacuum is inches of mercury denoted by "Hg, where (") refers to linear inches and Hg is the chemical symbol for mercury.

The most important point to understand about "Hg is that it is a measurement of differential pressure. In vacuum terms, this means that "Hg is the difference between the ambient atmospheric pressure and the vacuum that has been created in an application. Fig. 1 shows this graphically.

Inches of mercury refers to just that--a linear measurement of mercury. Fig. 2 illustrates a glass tube that is some 3-ft high. Mercury is poured into this tube and settles at the same height on both sides of the apparatus because the atmospheric pressure is the same on each column. When a vacuum is applied to one side of the tube, the higher atmospheric pressure pushes the mercury down, in this case, by 27 inches. Therefore, the vacuum being created is 27"Hg or 27 inches of mercury.

30"Hg is regarded as the maximum vacuum level available at sea level, and because the oceans are the same height across the planet, this is a good datum point for reference. This number is actually rounded up from 29.92"Hg. 29.92"Hg is the maximum difference in pressure based upon a known atmospheric pressure condition that is internationally agreed upon as 1,013 mbar or 14.7 psi at sea level. This atmospheric pressure continuously changes across the globe. In fact, the highest atmospheric condition ever recorded at sea level was 15.6 psi and the lowest about 12.5 psi, which was taken from within a hurricane. As the atmospheric pressure changes, the maximum differential available changes with it.

If, for example, the machinery was at a very high altitude, such as in Denver, Co., the atmospheric pressure is reduced and therefore, the possible DIFFERENTIAL pressure that can be created also is reduced. The average atmospheric pressure in Denver is about 12.1 psi, and the pressure differential that can be created is only 24.63"Hg. Therefore, vacuum-lifting apparatus would be less effective by this lower pressure differential or vacuum level.

Because of this forever-changing atmospheric condition, "Hg should only be used as a guide and in applications where accurate vacuum levels are not required, such as a process-type application. Inches of mercury is ideal for vacuum lifting with vacuum cups, as the amount of vacuum required is rarely high. Typical vacuum handling utilizes anything between 15"Hg and 25"Hg. Therefore, "Hg is suitable as a measurement of system performance in this type of operation.

For more accurate vacuum applications where the user must have a known vacuum level, an absolute vacuum unit should be used. Absolute pressure is the relevant factor here, and an absolute measurement takes its reading based on a datum point of zero. Zero is always zero and never changes. In North America, "torr" [a unit of measurement devised by Italian scientist Evangelista Torricelli

LO CA L SE DIS RV TR DIRECTIONAL CONTROL E BE IBU ST TOR VALVES !!! S

Circle 248

July/august 2012

(b.1608)] is very popular. Torricelli simply measured linear mercury movement using millimeters and based zero on a zero atmospheric condition. Therefore, 29.92 inches converted to millimeters is 760 (759.97). A system running at 50% vacuum is either 380 Torr or 15"Hg. However, the torr measurement scale is more accurate as it has with a datum point of zero atmospheric pressure. 15"Hg is a guide as it’s taken from a varying atmospheric pressure. This conversion is simple using 50%, but if the torr reading were 200, then the equivalent in "Hg would be 21.75. Refer to Fig. 3 for this comparative scale.

Outside of North America, the mbar(a) unit of vacuum measurement is used.

Like torr, this is an absolute pressure scale where 0 is zero atmospheric pressure and 1,013 mbar(a) is the standard for atmospheric pressure. This unit is easily converted to torr simply by multiplying by 0.760. Therefore, 500 mbar equates to 380 Torr.

Refer to Fig. 4 for the comparative scale.

Often used on a vacuum gauge is –kPa. This is a useful unit of measurement as it represents the percentage of vacuum and is widely used when discussing a general vacuum system. The user could, for example, explain to an engineer that they require “about 80% vacuum,” which is -80kPa from atmospheric pressure. Regardless of the location of these two people and what unit of measurement they are more familiar with, percentage vacuum is easy to understand and verbally communicate.

Fig. 5 compares all these measurement scales for easy reference.

Vacuum is the removal or reduction of atmospheric pressure. Depending on the application, the vacuum level may require a high accuracy, which means an absolute measurement unit such as torr or mbar(a) should be used, but in general vacuum applications, "Hg offers an easy guide to achieving a basic vacuum condition.

Control Unit HAWE Hydraulics

CAN-1014 control unit has four proportional outputs and four pulse-width modulation (PWM) out The puts, all of which can also be configured as inputs. These output ports combined with six analog inputs, which

have ranges between 0-10 V and 4-20 mA, mean the unit is flexible enough for the mobile construction equipment market. When used as a slave to enhance the company’s programmable logic valve control PLVC, functioning as both peripheral input and output nodes, it receives commands from the controller via the CAN-bus and sends back real-time data. This reduces the wiring necessary to control distributed valve banks. If all the outputs are configured as inputs, the unit becomes a dedicated input node. The unit measures 60 mm x 60 mm x 30 mm and is IP67 rated.

Temperature range is from 40ºF to 185ºF.

Considerations for a More Efficient Power Unit Circuit

By Tom Shickel, Manager, Marine & Offshore, Bosch Rexroth Corporation

ou’ve determined the power requirement for the next generation of your machine, and you’re ready to size the cooling circuit to achieve optimum energy efficiency. We all know the general rule of thumb: take the product of your pump flow and your operating pressure, and then divide by 1,714. Then, divide by 0.9 to account for the efficiency of the electric motor. Now, you assume 1/3 of the installed horsepower removal for cooling, and you are good to go, right? Well, maybe. Did you consider the full extent of your cooling needs? If the operation cycle has extended lulls, then this is likely sufficient. But what if you are running a constant repetitive cycle?

Heat loads can vary, from such small loads as the excessive warm ambient temperatures on piping and the reservoir to larger heat loads of servo systems, which may double the aforementioned rule of thumb from 1/3 to 2/3 of the installed system horsepower. An ideally sized cooling circuit can adequately cool new machines, but are you sure that all conditions will remain constant years down the road? Heat exchanger fouling factors, component retrofits, cycle-time changes, variations in water temperature, or ambient air temperature swings will all contribute to a skewed range of the original design. In addition, individual component degradation of the pump, motors, and valves will lead to compounding effects requiring greater cooling capacity. So what steps can be taken to ensure that your main drive unit and heat exchanger circuit are properly sized? With the right combination of component selection and circuit design, much of the heat load removal taxing the heat exchanger can be reduced through more efficient components, circuit configuration, and operating modes.

On the next page are five quick pointers for more efficient hydraulic power unit performance.

Fig. 1: Hydrostatic regenerative braking system makes commercial vehicles up to 25% more economical.

1

Don’t oversize the electric motor.

Over the past decade, manufacturers have standardized on premium efficient motors. Depending on the motor size, this premium efficient design upgrade generally improves efficiency by 5% when compared with its standard efficiency predecessor. This represents a significant energy savings over the course of a year. Yet, conservative designers may choose to over-size the motor in favor of superfluous safety margins. Ironically, the power-generation market tends to be the biggest culprit of this practice. In some cases, we’ve seen motors sized by as much as 20% over the maximum power requirement of the machine cycle. Running with an unloaded pump, a motor will still draw about 1/3 of the nameplate full-load current. This means that during cycle dwell times, an oversized motor could waste up to twice the energy that was saved with the efficiency improvements of the NEMA premium efficiency standards.

2

Select a variable displacement pump instead of fixed displacement, and be mindful of the compensator set point.

Most hydraulic design articles on energy efficiency describe a fixed-displacement gear pump blowing over a direct-operated relief valve as the benchmark for comparison.

While seldom put into practice these days, this circuit is analogous to having a variable displacement pump with a compensator set at a value too similar to that of the system relief valve.

If the pump compensator is set just over the system relief valve cracking pressure set point, tandem combination inadvertently performs as a very effective hydraulic heater. This oversight may go undetected; if the system pressure is only slightly

above the relief valve’s cracking pressure, only a marginal flow passes over the valve.

The actuators will not display any velocity reduction as long as the pump does not reach the compensator setting. The setting inefficiency is only revealed during operation points where the cycle is in a dead head mode. If the hydraulic system has a cooling circuit designed to remove 1/3 of the installed horsepower, you may be masking this inefficiency by simply running the cooling loop continuously.

For optimal efficiency in high-pressure circuits, make sure the system relief valve has the cracking pressure set at least 200 psi above the pump compensator or 10% higher than the pump compensator setting, whichever is higher. For lower-pressure circuits such as kidney loops, check valves should be used for the bypass safety instead of low-pressure relief valves to reduce set-up time and cost of material.

3

Optimize the pump controller for your application.

Over the years, variable displacement pumps have diversified their controller options to better match particular modes of operation. These options range from the general pressure controller to the most efficient electronic controllers, which closely match the load and speed requirements of the machine cycle.

July/august 2012

51

design considerations for a more efficient power unit circuit

A. Constant pressure control (Rexroth’s DR controller) is for pressure regulation. The pump compensator is set so the pump’s swash plate angle is de-stroked to zero-degree displacement once the working pressure reaches the regulating pressure setting. The pump supplies the flow necessary to maintain the pressure setting with a small amount of flow lost to pump leakage for lubrication and cooling.

B. Load-sensing (Rexroth’s DFR controller) is of similar design to the DR controller, but also includes a flow control regulator along with an orifice for a pressure and flow arrangement that will match the speed requirements of the system.

C. Horsepower control (Rexroth’s DFLR controller) further optimizes energy efficiency for applications such as presses or excavators where high-flow, low-pressure traversing ends with low-flow and high-pressure transitions. The flow and pressure profile always follows a constant horsepower curve.

D. Integrated electronics control (Rexroth’s DFEE controller) is a sophisticated controller for achieving energy efficiency with variable-displacement axial piston pumps. A closed-loop feedback command utilizes a proportional valve and onboard electronics to swivel the pump’s swash plate angle for optimum following error and accurate response to match the machine cycle needs. This solution offers easy control of speed, pressure, and power control.

4

Use a rear mount heat exchanger for cooling the leakage line.

All of the previous pump controllers have one common inescapable consequence of physics. In order to lubricate and cool the pump's internals, a portion of the pump’s flow efficiency is sacrificed as leakage. This small flow will frequently be the highest temperature fluid source in your whole circuit. Many people tend to overlook this heat source. A preliminary assumption would be that when the system is dead-headed, there is no heat generation. It is tempting to believe that, with no flow to actuators, there should be no pressure drop loss over valves and thus no need to cool through a return line heat exchanger. However, it generally takes less than a couple of hours of idle operation to discover that the high-temperature switch in the system has tripped.

This problem can be avoided with a separate filter kidney loop. But adding either a piggyback pump or a separate motor pump group will increase the energy consumption by a few horsepower. As an alternative, consider taking advantage of a rear-mount heat exchanger. This unit is a small air-oil cooler that mounts to the back of the main electric motor. It is designed for only small flows of 1 to 2 gpm. The air generated by the electric motor fan of the electric motor is enough to cool the leakage line of a variable displacement pump and thus prevent overheat52

July/august 2012

ing during long deadhead operations. As a result, you have additional cooling without the expense or power draw from an auxiliary pump.

5

Don’t set the thermostat too low.

All hydraulic fluids will have a temperature range that is ideal for operation. The viscosity grade of a fluid will determine where this should be maintained for your system-cooling parameters. Too often, operators assume that the lower the temperature of fluid, the better. But if you have filled your system with a high-quality VG 68 fluid and have the thermostat set at 100ºF, you miss the most efficient range of your cooling loop.

For example, let’s assume we have a separate filter cooler circuit with a water-oil heat exchanger with 80-degree cooling water maintaining a 100-degree reservoir temperature. In this case, our approach temperature is a mere 20 degrees. The electric motor and pump will therefore operate three times as long as a conditioning system set to maintain a reservoir temperature of 140ºF. This will lead to three times the electric energy usage and three times the cooling water required for system cooling.

y utilizing these design guidelines, it is possible to optimize not only the main system drive power efficiency, but also your cooling circuit efficiency so it performs at its peak levels. So is this the best we can hope for in fluid power efficiency?

Is there nothing more we can do to approach an ideal system where we may seem to ask the laws of physics to look the other way during certain modes of operation? Unfortunately, any power input in excess of the work output inevitably must be addressed by an adequate heat removal process. We can’t design a perfectly efficient system, but there are three application areas that are taking energy efficiency in fluid power to a new level.

Hydraulic regenerative braking (HRB) has been a recent development to establish energy savings on refuse service trucks for New York City. The frequent stop-and-go motion of the vehicle is assisted by a hydraulic circuit, which converts kinetic energy into potential energy and allows for energy savings of up to 20%. When the truck is braking, a hydraulic motor turns backward to act as a pump that stores hydraulic fluid as potential energy in an accumulator bank.

When the truck starts to accelerate, the motor operates in the forward direction and utilizes the accumulator volume for this power assistance with the engine.

Rotary active heave system (RAHS) operates on a similar energy-recycling concept. This system is most frequently used on large winch or crane functions on heavy lift rigs for the offshore market. As applications

continue to expand into deeper waters, more submersible structures are required that must be positioned on the ocean floor. This is accomplished while compensating for the wave heave motions of the craft on the water’s surface. This constant pay-in, pay-out cycle consumes a lot of energy. The winch pulls in the line on the ship’s descent from the crest of the wave to the trough to keep the load in a uniform motion. This step is followed by large energy dissipation from the subsequent braking function to govern the payout speed and acceleration when ascending to the subsequent wave crest. Without implementing a regenerative control circuit, the total energy input requirements and cooling requirements would be massive. Through Rexroth’s secondary control motor circuit and controls, we are able to reduce the input power requirements by up to 65%. Similarly, the cooling circuit is also 65% of the size that would be required on a system without secondary control.

Variable frequency pump drive (VSP) focuses on a different concept of energy savings.

Instead of recycling energy that is preserved from earlier deceleration motions, the VSP technology is centered around supplying pump flow to machine cycles on an as-needed basis. Here the electric drive speed is operated via a closed-loop PID circuit to adjust the pump speed to match the machine’s flow and pressure requirements. Rexroth refers to this class of products as its Sytronix variable-speed pump drives.

Its technology incorporates several combinations of frequency converters, electric drives, and pump configurations to meet system demands without the energy wastes indicative of constant speed pump/ motor drive systems.

Innovative Research/Educational Outreach Program Leads to Breakthroughs in the Application of Hydraulic Hybrid Technology

A

project to develop a hydraulic hybrid retrofit of a school bus, led by Dr. Michael Leamy at the Georgia Institute of Technology and his team of undergraduate and graduate engineering students, is yielding impressive results. Not only is their work realizing the potential of new fuel efficiencies for school buses, but it also is providing a model for effectively engaging college and pre-college students in hands-on learning about eco-friendly fluid power.

Over the last two years, Dr. Leamy and his students have designed, built, and begun testing a hydraulic hybrid propulsion system retrofit and biofuel conversion of a public school bus donated by the Atlanta public schools in Georgia. Much of the design and fabrication work to date has been carried out by undergraduates in Georgia Tech’s mechanical-engineering program; graduate students have taken on leadership roles in the project. Their work, originally funded by a grant from the Ford Motor Company Fund, has been further

enabled through donations of components as well as guidance from engineers at Eaton Corporation, Evonik RohMax, Linde Corporation, and Poclain Hydraulics—all industry affiliate members of the Engineering Research Center for Compact and Efficient Fluid Power (CCEFP). The CCEFP will provide funding for work during the project’s third year.

A school bus is ideal for hydraulic hybrid power due to its large mass and stop-and-go drive cycle. The hydraulic retrofit captures braking energy using a pump-motor, which first pumps hydraulic fluid into a high-pressure accumulator (thereby storing energy) and then releases this energy to the drivetrain through the motoring capability of the pump-motor. A microcontroller-based system developed at Georgia Tech controls the mode of operation of the pumpmotor, its displacement, and various valve components. Next steps involve incorporating complementary technologies using a clean-start technology in which the diesel engine is shut down at bus stops and restarted using a hydraulic motor, saving children from harmful emissions.

The hybrid retrofit has moved from the lab to the street, and tests are underway aimed at verifying predicted gains of over 20% in fuel economy. Considering that more than 700,000 gallons of diesel fuel are used by school buses each year in Atlanta alone, a 20% gain in efficiency could significantly lower both fuel costs and emissions through widespread adoption.

The impact of the project’s education and outreach effort grows, too, as more undergraduates and graduate students get involved, some even taking on the role of teachers as they use the bus to show pre-college students not only how hydraulic systems operate but also why the work of engineers is so important.

How to Solve Hydraulic System Overheating Problems

By Brendan Casey, HydraulicSupermarket.com

B

ased on polls I’ve conducted with my Hydraulics Pro Club members over the years, overheating ranks number two in the list of most common problems with hydraulic equipment. But unlike leaks, which rank number one, the causes of overheating and its remedies are often not as well understood. With the northern summer rapidly approaching, now is a good time for a little revision.

Why Do Hydraulic Systems Overheat?

Heating of hydraulic fluid in operation is caused by inefficiencies. Inefficiencies result in losses of input power, which are converted to heat. A hydraulic system’s heat load is equal to the total power lost (PL) through inefficiencies and can be expressed as PLtotal = PLpump + PLvalves + PLconductors + PLactuators.

If the total input power lost to heat is greater than the heat dissipated, the hydraulic system will eventually overheat. Installed cooling capacity typically ranges between 25% and 50% of continuous input power, depending on the type of hydraulic system and its application.

Hydraulic Fluid Temperature— How Hot is “Too Hot”?

tion of the oil. While the operation of any hydraulic system at temperatures above 82°C should be avoided, as I explained in my previous column, fluid temperature is too high when viscosity falls below the optimum value for the hydraulic system’s components. This can occur well below 82°C, depending on the fluid’s viscosity grade (weight).

Maintaining Stable Hydraulic Fluid Temperature To achieve stable fluid temperature, a hydraulic system’s capacity to dissipate heat must exceed its heat load. For example, a system with continuous input power of 100 kW and an efficiency of 80% needs to

be capable of dissipating a heat load of at least 20 kW. Assuming this system has an installed cooling capacity of 25kW, anything that increases heat load above 25 kW or reduces the cooling system’s capacity below 25kW will cause the system to overheat.

Consider this example. I was asked to investigate and solve an overheating problem in a mobile application. The hydraulic system comprised a dieselhydraulic power unit, which was being used to power a pipe-cutting saw. The saw was designed for sub-sea use and was connected to the hydraulic power unit on the surface via a 710-ft umbilical. The operating requirements for the saw were 24 gpm at 3,000 psi.

The hydraulic power unit had a continuous power rating of 37 kW and was fitted with an airblast heat exchanger. The exchanger was capable of dissipating 10 kW of heat at the prevailing ambient conditions at the work site or 27% of available input power (10/37 x 100 = 27). The performance of all cooling circuit components were checked and found to be operating within design limits.

At this point it was clear that the overheating problem was caused by excessive heat load. Concerned about the length of the umbilical, I calculated its pressure drop. The theoretical pressure drop across 710 feet of 3/4" pressure hose at 24 gpm is 800 psi. The pressure drop across the same length of 1" return hose is 200 psi. The theoretical heat load produced by the pressure drop across the umbilical of 1,000 psi (800 + 200 = 1,000) was 10.35 kW. This meant that the heat load of the umbilical was

0.35 kW more than the heat dissipation capacity of the hydraulic system’s heat exchanger. This, when combined with the system’s normal heat load (inefficiencies), was causing the hydraulic system to overheat.

Beat the Heat There are only two ways to solve overheating problems in hydraulic systems: • decrease heat load or • increase heat dissipation Hydraulic systems dissipate heat, albeit a relatively small amount, through the reservoir. Therefore, check the reservoir fluid level and, if low, fill to the correct level. Check that there are no obstructions to airflow around the reservoir, such as a build-up of dirt or debris.

Inspect the heat exchanger and ensure that the core is not blocked. The ability of the heat exchanger to dissipate heat is dependent on the flow rate and temperature of both the hydraulic fluid and the cooling air or water circulating through the exchanger. Check the performance of all cooling circuit components and replace as necessary.

Pressure Drop Means Heat As the long-umbilical story above illustrates, where there is a pressure drop, heat is generated. This means

that any component in the system that has abnormal internal leakage will increase the heat load on the system and can cause the system to overheat. This could be anything from a cylinder that is leaking highpressure fluid past its piston seal to an incorrectly adjusted relief valve. So identify and change-out any heat-generating components.

A common cause of heat generation in closed-center circuits is the setting of relief valves below, or too close to, the pressure setting of the variable-displacement pump’s pressure compensator. This prevents system pressure from reaching the setting of the pressure compensator. Instead of pump displacement reducing to zero, the pump continues to produce flow, which passes over the relief valve, generating heat. To prevent this problem in closed-center circuits, the pressure setting of the relief valve(s) should be 250 psi above the pressure setting of the pump’s pressure compensator (Fig. 1).

Whatever You Do, Don’t Let It Cook!

Continuing to operate a hydraulic system when the fluid is over-temperature is similar to operating an internal combustion engine with high coolant temperature. Damage is guaranteed. Therefore, whenever a hydraulic system starts to overheat, shut it down, identify the cause, and fix it.
