Abstract: A well pump includes a plunger reciprocally carried within a barrel between up stroke and down stroke positions. A tubular linear actuator housing located below the barrel has a rotatable rotor. An array of rotor magnets is mounted to the rotor, directing rotor magnetic fields in an outward direction. A cage is fixed against rotation relative to the housing and carried within the housing for axial movement relative to the rotor and the housing. The cage has a cylindrical inner sidewall surrounding the outer sidewall of the rotor. An array of cage magnets is mounted to the inner sidewall of the cage. The cage magnets direct cage magnetic fields in an inward direction relative to the axis. The cage and rotor magnetic fields interact such rotation of the rotor causes axial movement of the cage. A motor rotates the rotor.

Abstract: A well fluid submersible pump assembly includes a pump operatively coupled to a motor and a seal section located between the motor and the pump. The seal section has a single piece tubular housing with adapters secured to opposite ends of the housing. A shaft extends axially through the housing for driving the pump. An auxiliary seal carrier located in the housing has a central bore through which the shaft extends and has an outer diameter portion that seals to the bore of the housing. Opposed check valves in the seal carrier allow lubricant to flow from one side of the auxiliary carrier to an opposite side of the seal carrier in response to a selected pressure differential. A mechanical face seal mounts to the auxiliary seal carrier and seals around the shaft.
Abstract translation: 良好流体的潜水泵组件包括可操作地联接到电动机的泵和位于电动机和泵之间的密封部分。 密封部分具有单个管状壳体，其具有固定到壳体的相对端的适配器。 轴轴向延伸穿过壳体以驱动泵。 位于壳体中的辅助密封载体具有中心孔，轴延伸穿过该中心孔，并具有密封到壳体的孔的外径部分。 密封载体中的相对止回阀允许润滑剂响应于所选择的压力差从辅助载体的一侧流到密封载体的相对侧。 机械表面密封件安装到辅助密封载体并围绕轴密封。

Abstract: A reciprocating well pump assembly has a barrel and a piston reciprocally carried within the barrel between up stroke and down stroke positions. A travelling valve moves with the piston and has a closed position during the up stroke an open position during the down stroke. A relief port extends from a bore of the piston below the travelling valve into the barrel. A valve sleeve mounted around the body of the travelling valve is axially movable between a closed position, closing the tubular body relief port, and an open position, communicating well fluid in the barrel with the well fluid in the bore of the piston. When nearing the top of the stroke, the valve sleeve abuts a stop in the barrel. Continued upward movement of the piston causes the valve sleeve to open the relief port.
