Tribological Behavior of Friction Pairs in a High-Pressure Vane Pump under Variable Working Conditions

The tribological behavior of the friction pairs in a high-pressure vane pump under variable working conditions was experimentally studied; in particular, the effects of the varying sliding velocity (1.45–3.61 m/s) and contact pressure (0.11–0.44 MPa) on the friction coefficient and wear rate of the...
