摘要： A connection between a shaft and a coupling that preferably involves involute shaped splines is designed to reduce stress from torque applied to the shaft by a drive motor. To avoid stress concentration at the mouth of the coupling on startup, the shaft splines are made to taper from the shaft end down to the spline end. As a result, the initial contact with the coupling splines occurs within the coupling and removed from it mouth. The shaft is allowed to elastically twist in response to the applied torque as the contact area increases with shaft twisting and the contact line moves toward the mouth of the coupling. Stress concentration that formerly occurred at the coupling mouth is alleviated as some shaft elastic twist occurs without adding stress to the shaft splines until coupling contact is made.
摘要翻译：优选地包括渐开线形花键的轴和联轴器之间的连接被设计成通过驱动马达减小施加到轴的扭矩的应力。为了避免启动时联轴器口处的应力集中，轴花键从轴端朝向花键端部逐渐变细。结果，与耦合花键的初始接触发生在联接器内并从其中移出。当轴的扭转接触面积增加并且接触线向联接器的口移动时，允许轴响应于施加的扭矩而弹性扭转。以前发生在耦合口处的应力集中可以减轻，因为一些轴弹性扭曲发生，而不会对轴花键增加应力，直到形成连接接触为止。

摘要： A device, method, and program product detect and break an occurrence of gas lock in an electrical submersible pump assembly in a well bore based upon surface or downhole data without the need for operator intervention. The system provides the ability to flush the pump and return the system back to production without requiring system shutdown. In addition, the system provides an algorithm for controlling a pump operating speed of the electrical submersible pump assembly to maximize production from the well bore.

摘要： A device and method can detect, and also break, an occurrence of gas lock in an electrical submersible pump assembly in a well bore based upon surface or downhole data without the need for operator intervention. To detect an occurrence of gas lock, an instantaneous value is monitored using a sensor. Then a controller compares the instantaneous value to a threshold value over a predetermined duration to thereby detect the occurrence of gas lock in the electrical submersible pump assembly. Sensors can include, for example, a differential pressure gauge, a pressure gage located in a pump stage located toward the inlet, a fluid temperature sensor located toward the discharge, a free gas detector located near the pump discharge, an electrical resistivity gage, a flow meter located within surface production tubing, and a vibration sensor attached to a tubing string to measure a vibration signature.

摘要： A submersible well pump assembly has a gas separator that separates gas prior to entering into the pump. A shroud encloses a portion of the pump assembly, including the gas separator. The gas separator has gas discharge tubes that extend from it out through the shroud. The gas discharge tubes are tangentially aligned to create a vortex on the exterior of the shroud.
