Linear Motor Based on AMEsim Modeling and Flow Characteristic Research of Reciprocating Pump

Traditional rotary motor is complex and not easy to regulate and contro.Based on characteristics of linear motors,this is a research of linear motor that directly drives the piston rod of reciprocating pump to do reciprocating motion.It establishes the motion model of a reciprocating pump system,and uses AMEsim to simulate according to the traditional law of reciprocating movement of the pumping system.The simulation results show that,using reasonable control system,linear motor piston reciprocating pump performance motion such as displacement,velocity,acceleration,and pump flow rate output are more stable.This study theoretically and basically eliminates the reciprocating pump output flow pulse,which can meet the requirements of modern machinery for reciprocating pumps,and it has some significance in promoting the application of linear motor reciprocating pump.
