Analyzing a Hydraulic System Performance: If You Can Study It, You Can Improve It

To improve how a hydraulic system works, including reducing the amount of energy it consumes, you need to record and analyze data on how it currently operates and analyze it. That’s what Luis Javier Berné of IhBER S.L. of Zaragoza, Spain is doing. IhBER designs hydraulic systems and distributes hydraulic system components. The company previously developed the designs for all of the hydraulic controls of a side-loader refuse truck, including the control system that powers the lifting arm. Though the system works fine, IhBER engineer Berné has been analyzing its operation to see if it could be improved. Berné’s work played a large role in his studies leading to a Ph.D. at Universitat Politécnica de Catalunya, LABSON Fluid Power Laboratory, in Terrassa (Barcelona), Spain.

Closed-Loop Control Enables Precise Press Operation

For many press applications, precise, coordinated motion holds the key to maximizing productivity and minimizing waste and maintenance costs. Whether working on a new press or retrofitting a control system to an old press, success often rides on the capabilities of the motion controller. Here, using a hydraulic press as an example, the controller ensures operational repeatability–achieving tight control of ram speed and force applied. In turn, this necessitates using the right transducers and valves, and a motion controller with closed-loop control and fast cycle time.

Successful pressroom performance, in many cases, hinges on the motion controller's ability to accurately synchronize the motion of multiple axes–critical when the job requires a level platen as multiple compression rams operate, or on presses that form parts between two active hydraulic actuators.

Motion Control for a Heavy Duty Test Stand

NTS Corp., headquartered in Anaheim, California, offers testing, inspection, and certification projects for many industries, including aerospace, defense, automotive, and consumer markets.

“We have well over 150 different tests going on at the same time at our 125-acre Huntsville, Alabama, location alone,” says Jim Birkholz, NTS Huntsville design engineer.

The Huntsville facility uses some large-scale test systems. For example, one test stand developed by NTS, a swing table, weighs about 17,000 lb and has been designed to test naval and aerospace assemblies weighing up to 50,000 lb. The system has been used for testing the integrity of helicopter fuel tanks and for testing jet engines.

Multi-Axis Motion Controller Accelerates Gear Testing

Materials testing and characterization is often a lengthy process. It can take more than a year and billions of testing cycles for a manufacturer to characterize the properties of a new metal compound to be used in a critical application such as a component of an automotive or jet engine.

Typically, the testing regimen is prescribed by an OEM in accordance with procedures specified in industry organization standards; for example, one testing method for bending fatigue of gear steels is outlined in SAE Standard 1619 using a standard fixture and standard gear design. Companies manufacturing automotive and aerospace engines often refer to this and other standards as they specify the materials and designs of gears to be used in their applications, as do companies manufacturing test systems that verify production gears meet the standards.

RMC200 Receives PROFINET Certification

PROFINET

Delta Computer Systems, Inc. is pleased to announce that PI has certified the RMC200 as a PROFINET IO device. Delta is committed to ongoing development and support for a wide variety of industrial communications protocols, ensuring our customers have the benefits of fast, precise servo-hydraulic and servo-electric control. With the next firmware release (early Q1 2019) the RMC200 will join the RMC150 and the RMC75 as PROFINET communications certified devices.

Prewired Cables Available for RMC200 Modules

Delta Computer Systems now offers prewired cables for the RMC200 to speed installation. These compact cables provide a convenient option for short runs within a cabinet from the RMC200 I/O modules to terminal blocks. These six foot long cables (standard length) are prewired to a terminal block on the module side, running to pigtailed ends for user connection flexibility.

Distributor Highlight

IhBER S.L.

IhBER S.L. is a full-service hydraulic distributor located in Zaragoza, Spain. Founded in 1984, IhBER provides experienced design services, skilled installation and commissioning, and responsive technical support and system maintenance services. IhBER distributes a full line of servo-quality valves and position sensors along with the RMC Motion Controllers, providing a complete precision system solution.

IhBER designs and builds innovative hydraulic power units (HPUs) for a variety of industries and applications. Energy efficiency is a particular area of interest, and IhBER's engineers have designed and built HPUs that change power consumption to match the required output, but will shut down one or more motors automatically when the oil demand drops. Delta congratulates IhBER for 35 years of business.
