Optimal Design of Main Parameters for Pumping Unit of Automotive Power Steering Units

We should clean the internal residual hydraulic oil after the automotive power steering units are carried out performance test according to the requirements. In the sake of pumping more residual hydraulic oil efficiently we develop the special pumping unit Based on the orthogonal test, the optimal design of the main parameters pumping unit of automotive power steering units that is the first adding gas time, adding gas interval and adding gas time has been completed in order to determine the optimal program to achieve the best pumping effect.
