1、 I 三缸单作用钻井往复泵空气包设计 摘要 往复泵在当今社会的工农业生产上发挥着重要作用，其次还在科研和国防上面 有着广泛的应用。但是往复泵自身存在的脉动流量问题对其使用性能有着明显的约 束作用，因此减小往复泵中由于脉动流量产生的压力波动是至关重要的。 本文主要说明了合理适当的空气包设计对于促进往复泵工作性能和减小压力波 动的重要作用。根据以往的课题研究进行分析，查明不足之处从而进行深一步的课 题实验理论研究，完善空气包的工作性能。 文中主要通过对往复泵的整体设计和对空气包的分析研究， 从而完成课题目标： 优化空气包尺寸大小，然后再对空气包进行强度校核和受力分析，从而达到完善空 气包作用性能的

2、目标。 空气包的设计原则和作用机理是整个课题的关键症结所在，所以我们需要在理 论分析的基础上进行进一步的实验探究和优化设计， 来改善往复泵的整体工作性能。 关键词：往复泵，空气包，压力波动，优化设计关键词：往复泵，空气包，压力波动，优化设计 II ON THE DESIGN OF THREE CYLINDER SINGLE ACTING RECIPROCATING PUMP AIR BAG ABSTRACT Reciprocating pump plays an important role in industrial and agricultural production in todays
