摘要:
An electrical submersible pump assembly includes a centrifugal pump having impellers and diffusers. A thrust runner is coupled to a motor shaft for rotation along with the impellers. The runner receives thrust from at least one of the impellers and transfers the thrust to a bushing non rotatably mounted in one of the diffusers. The bushing has a thrust transferring end adjacent a thrust receiving shoulder in the diffuser. The bushing is axially movable in the receptacle. An annular spring located between the thrust receiving shoulder in the receptacle and the thrust transferring end of the bushing urges the bushing away from the thrust receiving shoulder.
摘要(中):
电潜泵组件包括具有叶轮和扩散器的离心泵。 推力滑轮联接到马达轴上以与叶轮一起旋转。 转轮从至少一个叶轮接收推力,并将推力传递到不可旋转地安装在一个扩散器中的衬套上。 衬套具有与扩散器中的推力承受肩部相邻的推力传递端。 衬套可在容器中轴向移动。 位于容器中的推力接收肩部和衬套的推力传递端之间的环形弹簧促使套管远离推力接收肩部。
