plunger stroke的例句大全

A new method for calculating plunger stroke loss of deep well pump

一种计算深井泵柱塞冲程的新方法

In this paper discrete optimization is applied to a sucker-rod pumping for seeking optimum parameters, such as length of stroke, pumping speed, plunger diameter and pump depth.

运用离散最优化的理论和方法优选了有杆泵抽油井的抽汲参数，包括：冲程、冲次、泵径和下泵深度。

When the pump cylinder could not be filled with enough liquid, the liquid shock will occur, and the liquid shock load will make the down stroke axial load of the plunger increase.

当油井供液不足时，柱塞下冲程时泵内将产生液击，并加大柱塞下行阻力；

To satisfy the requirement of ultra-long stroke, two or more plungers spaced 100m ￣ 150m apart are adopted as a series plunger of the special subsurface pump, and the tubing string as the pump barrel.

为满足超长冲程的需要，采用两个或更多个相互间距离为100～150m的柱塞串联成特种抽油泵的多节柱塞，用油管作为特种抽油泵的泵筒。
