Wear Analysis of Vanes Pumps Running With Thickened High Water Based Fluids

The analysis of wear in hydraulic equipment is one of the main fields of research at the Insitut fur hydraulische und pneumatische Antriebe und Steuerungen (IHP) of the RWTH Aachen. Especially wear of rotary hydraulic machinery is being investigated in several projects. One of the most frequently applied methods in this field is vibration and noise emission measurement. To determine the wear properties of hydraulic pumps running with a new type of thickened high water based fluids (HWBF), a test procedure was configured and carried out at the IHP.
