Research on Response Characteristic and Efficiency Characteristic of Pump control motor System

The simulation model of a pump-control-motor system was established .Research simulation and test verification were carried out of response characteristic of the system .The findings were as follows:the displacement ratio of variable pump was decided by the current singal , the rotational speed of the fixed motor was decided by the current singal and the rotational speed of pump togeth -er.The efficiency model of hydrostatic system was performed .Research comparsion and test verification of efficiency characteristic were carried out .The research results show below: the pump-control-motor system has good efficiency characteristic within range of larger displacement , moderate pressure and moderate or higher rotational speed of the pump and the motor .
