This solution relies on the sequential pump-down conveyance and placement of plugs using Wireline to temporarily isolate sections of the well to be hydraulically fractured.

该技术使用电缆安放桥塞或泵送桥塞来暂时隔离井段进行水力压裂。

Atmospheric pressure then pushes the piston back down the cylinder, and if anything (such as a pump) is attached to the piston, some useful work can be done.

于是，气压就会再次将活塞推至汽缸底部。而假如有诸如水泵这样的物体与活塞连接，就可以在活塞的带动下完成一些工作。

Steam generated by the heat of a cooling down reactor has enough force to run a turbine, which then runs a pump that provides coolant to the core.

由冷却的反应堆产生的蒸汽足够运行一台涡轮机，然后该涡轮机运行一台水泵为反应堆提供冷却剂。

It signals a winding down of the pump-priming policy brought in to maintain high economic growth in the wake of the Asian financial crisis of 1997.

But it appears to be a catalyst-driven chemical system that releases both heat and gas in sufficient quantities to pump the wings up and down.
