摘要: A well pump assembly has a barrel, a standing valve at an upper end of a standing valve chamber, and a plunger. A travelling valve admits well fluid into the barrel during a fill stroke. The travelling valve closes during a power stroke so that the plunger pushes well fluid from the barrel into the standing valve chamber. A gas release port extends from the standing valve chamber to the exterior of the pump assembly. A check valve in the gas release port has an outward flow blocking position for blocking liquid well fluid in the standing valve chamber from exiting through the gas release port while the plunger is in the power stroke. The cheek valve has a gas release position that enables gas present in the standing valve chamber to flow out the gas release port while the plunger is in the power stroke.

摘要翻译: 井泵组件具有桶,在立柱阀室的上端处的竖立阀和柱塞。 在填充冲程期间,行进阀允许流体进入筒体。 行程阀在动力冲程期间关闭,使得柱塞将良好的流体从筒体推入到立式阀室中。 气体释放口从立式阀室延伸到泵组件的外部。 气体释放口中的止回阀具有向外的流动阻塞位置,用于当柱塞处于动力冲程中时,阻止立式阀室中的液体井流体离开气体释放口。 止回阀具有气体释放位置,使得当柱塞处于动力冲程时,存在于立式阀室中的气体流出气体释放口。
