摘　　要：随着有杆泵采油下泵深度的增加,泵断、泵脱等故障也呈增长趋势。分析抽油泵上游动凡尔罩的受力情况,发现出油窗和进油罩螺纹根部退刀槽处为其强度薄弱点。采用增加出油窗壁厚和去掉螺纹退刀槽的方法来提高抽油泵的强度,运用计算机辅助工程设计,逼真地模拟出设计者的结构设计思路,有效地缩短产品开发周期,节约了试验成本。The faults such as pump breaking and pump trip are increasing with the sucker -rod pump going deeper for oil production .Through analysis of load -carrying capability of pump＆#39;s traveling valve cover ,it is found that its vul‐nerable points lie in oil window and tool withdrawal groove at the root of thread of oil -taking cover .The pump＆#39;s stress intensity is increased by adding wall thickness of oil outlet and removing gewindefreistiche .
