摘　　要：直线电机抽油泵是一种新型高效节能的采油装备,泵阀总成是制约其工作效率提高的关键因素之一。本文运用计算流体力学方法,对所设计的泵阀总成进行了三维数值模拟,计算结果正确反映了流场状态,得到了阀球运动特点。通过研究不同柱塞冲程和冲次参数组合情况下阀球运动,评价了泵阀总成的启闭和导向性能,设计符合要求。研究结果对直线电机抽油泵泵阀设计具有指导意义。High efficient and energy saving are the Characteristics of oil pump driven by linear motor. Valve is one of key parts. Based on eom.putational fluid dynamics, numerical stimulations for the fluid field around valve. The motion features of ball valve was obtained. Open-close and guide performances were evaluated by analyzing the motions of ball valve in different strokes and strokes per minute of pump. The conclusions can provide scientific basis for designing valve.
