External Gear Pump Performance With Graphene Hydraulic Fluid
ASME/BATH 2023 Symposium on Fluid Power and Motion Control, 2023 Abstract The literature reports that the addition of nanoparticles to hydraulic fluids significantly improves their fundamental properties such as viscosity index, lubricity, and anti-wear performance. Among the others, graphene-based nanomaterials are a potential candidate for hydraulic nanofluids due to their atomic thickness, high ...

Pressure transients in an external gear hydraulic pump
Proceedings of the JFPS International Symposium on Fluid Power, 1993 A measurement technique, that extends and integrates former experimental activities, has been developed to detect the variation with time of tooth space pressure in an external gear pump by use of a pressure transducer fi tted in the driver gear. The pressure signal from the miniature strain gauge sensor mounted in the bottom of the tooth space is ...
