A Study of Wear Characteristics Due to Pressure for Hydraulic Fixed Displacement Vane Pumps.
Abstract
This project was undertaken to determine if the wear rate of a hydraulic vane pump can be correlated to its operating pressure. The correlation should be that the wear rate of the pump would be a linear function at low operating pressures and reach an exponential function of the pressure at some elevated pressure. According to MSO FPI Report no. 50423 dated July 15, 1982 MERADCOM contract no. DAAK70-81-C-0002, operating the pumps at test pressures of 115 percent of rated pressure caused normal wear of the pump. The pumps were broken-in using two different methods to determine if the wear rate operating pressure characteristics will differ for pumps that are broken-in at 3000 PSI for three hours compared to pumps that are broken-in at 500 PSI for three hours prior to running the wear rate test. There are two main considerations in performing the wear rate test. The first is to develop a test procedure. The test procedure consists of methods to determine the wear rate of the pump by utilizing on-hand laboratory equipment and instrumentation. The other consideration is to determine which types of oil analysis are suited to this project. Several methods were investigated and used to collect wear rate data through analysis of the pump's fluid.
