Hydraulic fluid will have innate properties originating from its base stock, but will also contain additives to improve performance factors such as lubricity, corrosion protection, viscosity index and water saturation, to name a few. If a high quality hydraulic fluid came from the factory with excellent properties, how can we guarantee that oil … [Read more...] about What is oil sampling?
As a sealing product, O-rings have been a very cost-effective and simple choice since the 1940s. However, there does seem to be some mysticism about how these relatively simple shapes actually function. Robert W. Keller, PhD, Director of Technology Sales at Freudenberg-NOK Sealing Technologies explains that in reality, the simple physics and the … [Read more...] about How do O-rings work?
Automatic particle counting is a key to keeping track of fluid cleanliness in within a hydraulic system. Dan Zoller, Group Product Manager Filter Systems at Schroeder Industries says that a common practice has been to take oil samples from the system and have them sent to a lab for analysis, or evaluated on site by hand (e.g. Patch test with … [Read more...] about What is automatic particle counting?
Trelleborg Sealing Solutions announces its new Primary Flight Control Seal Test Bench at FIA 2016 (Farnborough International Airshow) being held in Hampshire, England, from July 11-17. Located in the HA Traub Technical Center in Fort Wayne, Indiana in the U.S., this test equipment can uniquely offer a rapid multi-million cycle testing capability, … [Read more...] about Primary flight control seal test bench launched
Any hydraulic system user must take contamination and cavitation prevention seriously, as these two activities can severely damage components and machinery. One such answer to these problems is HYDAC's OXiStop LID series, a tank solution for hydraulic systems with an integrated, hydraulically driven degassing and dewatering unit. It is designed … [Read more...] about OxiStop tank prevents contamination and cavitation
Contamination is widely recognized as the leading cause of premature failure in fluid-power systems. Thus, keeping contaminants in check helps ensure components and systems perform as intended and last a long time, with minimal unscheduled downtime. Heed the following advice for proper fluid power contamination control. Contamination comes in … [Read more...] about The importance of fluid power contamination control
Hydraulic fluid is the energy transfer medium in all hydraulic systems. This simple function is only achieved by a fluid that does not easily trap gasses. Trapped gas and foaming problems would bring a higher level of compressibility to a fluid that is usually relied upon to support a very stiff, fast reacting system. Where transmitting energy … [Read more...] about Why are hydraulic fluids used?
Demand for higher efficiency, enhanced output and tolerance of tough terrains make it increasingly more difficult to ensure machines perform at their peak. High-performance hydraulics may be built for these conditions; however, good fluid-handling practices can keep equipment running better, longer. Particulate and moisture contamination of … [Read more...] about Clean hydraulics: contaminant removal
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
Just having a hydraulic fluid management plan in place doesn’t mean that you are doing it correctly. Managing your lubrication properly is critical in maintaining clean, efficient hydraulic systems, said Jason Kopschinsky, CMRP, director of reliability services for Des-Case. “Not approaching lubrication in a holistic manner, including lubricant … [Read more...] about Follow these 5 simple tasks for efficient hydraulic fluid management
