    Abstract
  • A new type of asymmetric cam-rotor double-stator vane pump was developed to deal with the shortcomings of traditional hydraulic pumps. Two inner and outer stators and one rotor are arranged in the casing of the vane pump, in which the numbers of protrusions inside and outside the rotor are different, so that the vane pump can output multi-stage constant flow, and simultaneously supply oil to multiple systems. The operation principle and characteristics of the vane pump are explained . Through the analysis on the internal structure of the vane pump, the theoretical flow of the inner and outer pumps of the cam rotor at different rotation angles is deduced, and then the instantaneous flow of the vane pump in different working modes is obtained. A test platform for the asymmetric cam-rotor double-stator vane pump was built. The test results show that the flow pulsation of the asymmetric cam-rotor vane pump is 2% less than that of the conventional symmetric vane pump with double convex cams. The test results are basically consistent with the theoretical analysis, which verifies the correctness of the theoretical analysis.
