    Abstract

    Several test procedures with the Vickers V 104 C are compared with those of the Vickers VQ-series to show their different technological properties and tribological options for testing. Based on these investigations, the wear results achieved on different test rigs can be interpreted to form a statement on the actual scope of hydraulic pump testing with Vickers vane pumps. Starting from this and including the requirements of industry together with stimulations coming up from new developed fluid analysing devices, the demands for a new pump test method can be derived. Therefore, a comprehensive structure and stress analysis and the documentation of basic wear characteristics in the vane pump V 104 C using a pure mineral oil without additives will be introduced. Thus wear results achieved with this pump and the 35 VQ 25 using identical commercial fluids can be compared. Wear maps derived from wear calculations and verified with wear results obtained with the pure mineral oil can be used to estimate the test performance of the 20 VQ 5 as a substitute for the V 104 C, and will allow a theoretical explanation of the empirically derived upper wear limits used in all vane pump test.
