Fluid Power World contributing editor, Carl Dyke, founder of CD Industrial Group, has related a number of field-service issues he’s come across over the years. One was discussed in the recent post, “Troubleshooting tales from the trenches.” Here’s another real-world application, from Carl’s presentation at the 2017 Fluid Power Technical Conference … [Read more...] about The baffling, ballooning cylinder
Mobile Hydraulic Tips
One of Fluid Power World’s resident technical experts, Carl Dyke, has related a number of field-service issues he’s come across over the years. In a presentation at the 2017 Fluid Power Technical Conference in Milwaukee, he enlightened us on one mobile application that had the machine owners scratching their heads. This one cropped up last … [Read more...] about Troubleshooting tales from the trenches
The ICM – 2.0 in-line contamination monitor, developed by MP Filtri in Milan, Italy, automatically measures and displays particulate contamination, moisture and temperature levels in various hydraulic fluids. It is designed specifically to be mounted directly to systems, where ongoing measurement or analysis is required, and where space and costs … [Read more...] about In-line contamination monitor offers user flexibility
Filtration systems are used anywhere upgraded or auxiliary filtration is required in a hydraulic system. A filtration system is available in either permanent kidney loop circuits or portable filter cart assemblies. Either system is used to improve the cleanliness of the hydraulic fluid in a hydraulic machine. Often, filtration systems are used to … [Read more...] about Where are filtration systems used?
Illustration shows a high-performance filter element. Photo courtesy of Pall Corp., 2015. Hydraulic filters are used anywhere in a hydraulic system particle contamination is to be removed. Particle contamination can be ingested through the reservoir, created during the manufacture of system components, or generated internally from the hydraulic … [Read more...] about Where are hydraulic filters used?
Without a doubt, clean hydraulic fluid is the ultimate lifeblood of a hydraulic system. Contamination can reduce efficiency and possibly destroy machinery. That’s why many companies invest in offline filtration systems, commonly referred to as filter carts or kidney loop systems, for the external filtration of hydraulic fluids. Although … [Read more...] about Offline filtration ensures clean-running, efficient machines
Viscosity index is a dimensionless number that represents how the viscosity of a hydraulic fluid changes with temperature. (It also applies to fluids like engine and automatic transmission oils, gear lubricants, and power-steering fluids.) The greater the viscosity index (VI), the smaller the change in fluid viscosity for a given change in … [Read more...] about What is viscosity index?
Schroeder Industries released the MFD-MV High Viscosity Mobile Filtration Systems. The MFD-MV cart is capable of handling fluids of up to 5,000 SUS, at 6 or 10 gpm, bridging the gap between the regular carts and the MFD-HV high viscosity cart for fluids up to 10,000 SUS The MFD-MV is a compact, self-contained filtration system equipped with … [Read more...] about High viscosity mobile filtration systems from Schroeder Industries
You’ll have to excuse my shade of indigo. I’m not sure if it’s more Smurf or Na’vi, but back when I first started writing about fluid power, I promised I’d talk about fluid conditioning until I’m blue in the face. I’ll live with the odd skin tone, because fluid conditioning is still one of the most important topics related to hydraulic … [Read more...] about What is hydraulic fluid conditioning – part 1
Bosch Rexroth has developed a filter sizing program that allows users to input various parameters such as fluid type, fluid viscosity, system temperature, and micron rating to evaluate the pressure drop across Rexroth filters. The sizing software (Filter Select) can be used to quickly determine the best filter for a specific hydraulic application … [Read more...] about Easy to use hydraulic filter select tool
