Abstract
The oil pump is the power source of the hydraulic assisted steering system. Based on the analysis of the comprehensive performance technology of Yuejin brand automobile oil pump, this paper designs the hydraulic circuit of the test bed according to the test standard of the oil pump, and designs the inspection system which can finish the oil pump type test and the factory test automatically Test Bench.
The hydraulic part of the Yuejin brand automobile oil pump test bench mainly adopts the electro-hydraulic proportional valve technology to load the oil pump to realize the correction of the pressure and flow performance and parameters, and designs the oil pump test bed which meets the actual demand. This paper focuses on the electro-hydraulic Scale technology to introduce and analyze, and its main function used in the design.
Finally, the oil and oil flow test was carried out with the Yuejin brand automobile oil pump as the test object. According to the relevant standards, the test results meet the technical requirements. The test data show that the test bed has achieved the expected target.
