【Abstract】 In order to acquire the starting and working characteristics of a piston pump pressurization system,the dynamic model of the piston pump pressurization system is established.based on the AMESim simulation platform,and the starting and working process of the system was simulated.Different position pressure curves of the system,effect of the accumulator on the piston pump outlet pressure and the influence of flowrate on the working frequency of pump were obtained.The results show that the system start-up process is reliable and rapid,and the higher output pressure of the pump is stable.The simulation results are conformable with test data,which proves that the simulation model is reasonable and method is feasible.更多还原
