为了防止抽油泵柱塞上凡尔罩断脱,提高抽油泵泵效,对原抽油泵柱塞上凡尔罩结构及材质进行了分析。针对目前的不足,从结构和材质上进行了优化,设计了深井泵新型高效柱塞。通过现场150 多口井的应用资料分析,改进后的柱塞具有防止上凡尔罩断脱,提高泵效,适应性强等特点,推广应用前景良好。

In order to prevent the topside valve housing of the plunger from breaking and increase the pumping efficiency , we analysed the texture and material of the original and find it s failure. Then we designed this new type high efficiency plunger for deep well pump by optimizating the texture and material. Having been used in over 150 wells , it was concluded that the modified topside valve housing of the plunger is high efficiency , not break , high suitability and the pumping efficiency is improved.
