阀球入座时间对抽油泵泵效的影响

作者定量地分析阀球入座时间对抽油泵泵效的影响,推导了泵效损失的计算公式。从分析中获得的结论可供设计阀罩,阀球时采用。也可指导抽油方式和参数的选择。文中除列入一些计算公式外,还附有据以计算入座损失的诺模图。

Pumping Efficiency Affected by the Seating Time of Valve Ball

In this article the authors analyse quantitatively the effi-ciency of oil-well pump affected by the time of valve ballfalling into its seat, and derive the formula for calcula-ting the efficiency. The authors say conclusions from theanalysis is applicable to the structure design of valve andto the selection of pumping types and parameters. Someother calculating formulae and a nomograph are offered.
