摘　　要：为研究对峙式乳化液泵液力端的应用情况,采用AMESim对对峙式乳化液泵系统进行仿真,获得吸、排液阀及柱塞运动曲线和泵的流量曲线,得到阀芯启闭滞后原因及容积效率,并对排液阀芯锥顶角进行优化,得出最优角度。通过仿真分析得出,该流量压力下泵的阀芯启闭滞后原因主要是由于乳化液的压缩性引起、容积效率为98.1%、排液阀芯锥顶角最优角度为120°,上述结果为对峙式乳化液泵的推广和整体优化设计提供依据。In order to study the safety application of confrontation emulsion pump,AMESim software was used to establish the hydraulic system of confrontation emulsion pump,obtaining the curve of absorbing/discharging valve and piston movement and the flow curve of the pump,The reasons for valve core opening and closing lag and volumetric efficiency were obtained;the cone-top Angle of discharging valve core was optimized,getting the optimal Angle.Through the above simulation,it was found that the flow and pressure of the pump valve core opening and closing lag reason is caused by the compressibility of emulsion,with volumetric efficiency being 98.1%and the optimal angle of discharging valve’s cone apex Angle 120°.These findings of the research provide the basics for the popularization and overall optimization design of confrontation emulsion pump.
