Hydraulic fluids aimed at energy savings
Early field test results show promise in the effort to boost the efficiency of mobile fluid power applications.
According to a story in Design News , as part of an industry-wide effort, a coalition of university researchers and industry suppliers organized through the NSF-sponsored Center for Compact and Efficient Fluid Power (CCEFP) is working together to boost the efficiency of fluid power applications. The center is supported by seven participating universities and 55 industrial partners.
New multi-grade oils, optimized with high-tech polymer additives and friction modifiers, are delivering promising field results, and new hydraulic fluids have been introduced by major oil companies. Research is moving ahead on duty cycle standards for specific vehicles, and the impact that high-efficiency hydraulic fluids (HEHF) could have on overall equipment design, particularly high-pressure and high-temperature applications such as excavators, skid steer loaders, and construction equipment.
