摘要： An electrical submersible pump assembly (ESP) includes a pump section, a motor section, and a seal section. In one embodiment, an exterior of the pump section defines a gripping indentation above the pump intake. Alternatively, a clamp member may be provided that surrounds the pump, wherein the clamp member defines the gripping indentation. A collet adapter is affixed to an upper end of a shroud. The collet adapter has gripping members that engage the gripping indentation for attaching the shroud to the electrical submersible pump assembly. The collet adapter is provided to ease installation of the motor shroud onto the ESP as well as to ease removal of the motor shroud from the ESP. The collet adapter of the present invention eliminates precise alignment and bolt-on requirements of typical motor shroud mounting techniques.

摘要： A flapper valve assembly is described having an equalizing port assembly with a bleed valve member that is moveable between an open position and a closed position. The equalizing port assembly features a structural support member in the form of a retainer key that is secured to the flapper valve member both axially and radially. Additionally, a compressible spring is located between the structural support member and provides biasing force upon the valve member to urge it toward a closed position. Additionally, the flapper valve member presents a pair of raised, substantially flat actuator contact portions upon its downstream face to meet an actuating tube in a mating contact arrangement and resist material deformation that could tend to clog or block the equalizing fluid flow port.

摘要： A centrifugal pump has a stationary diffuser with a bore. A thrust bearing is pressed into the diffuser bore and has a curved interior. A thrust runner having a curved exterior is correspondingly and closely received by the thrust bearing interior. The thrust runner is keyed to a shaft and transmits thrust from a rotating impeller to the diffuser via the thrust bearing. The curved surface of the thrust bearing allows for handling of both axial and radial thrust without the need for multiple thrust bearings. The increased surface area of the curved surface in the thrust bearing can also handle higher loads.

摘要： A multi-stage submersible pump uses impellers having only one shroud to provide stages with shorter stack lengths to allow more stages per housing and more head pressure per housing. The impellers are biased with wave springs to keep the rotating impeller vanes close to the mating diffusers. The entire stack of impellers is assembled in contact with each other using the wave springs and are always under axial load. The wave springs also take up any tolerance variations in the stack to keep the impellers in proper running position. To keep the impellers in their proper locations, thrust washers formed from hard materials are used between adjacent impellers to avoid erosion thereof.
