A type of fluid pump in which reciprocating pistons or plungers displace the fluid.

流体泵的一种类型。它的往复运动的活塞或柱塞驱替流体。

For the viscosity or density change in the process fluid, the pump will not be affected too much.

对于粘度或密度在工艺中有变化的流体，这种泵不会受到太多影响。

This pump impeller blades can be adjusted automatically to adapt to speed, fluid viscosity and pressure.

这种泵的叶轮叶片可以自动调节来适应转速、流体粘度和不同压力。

The downhole oil water separation system is comprised of double fluid flow pump, cyclone separator and oil pump.

井下油水分离系统由双液流泵、旋流分离器和原油提升泵三大部分组成。

What happened, the pre-treat (chemical), we think, flooded the pump separator and we may have got some fluid where we didn't want it and it'll take us a while to work through a procedure to recover.

发生了什么事，我们认为，是预处理(化学)淹没了泵的分隔器，我们会在不想要流体的地方得到一些流体，这将要我们花一段时间完成一套程序来修复它。
