    摘要: A well pump assembly has a submersible well fluid pump, motor, and seal section with a seal section shaft for transferring rotation of a motor drive shaft to a pump drive shaft. The seal section has a shaft passage through which the seal section shaft extends. A movable compensating element has an interior containing motor lubricant that is in fluid communication with motor lubricant in the motor and also in fluid communication with motor lubricant in the shaft passage. A shaft seal restricts well fluid from entry into the shaft passage. A lubricant pump driven by the shaft has a discharge within the shaft passage below the shaft seal. A recirculation passage extends from the shaft passage at a point between the discharge of the lubricant pump and the shaft seal to the interior of the compensating element.

The balance drum includes a rotor rotationally fixedly connected to the shaft, the rotor having a high and low pressure sides, a stator stationary with respect to the housing, a relief passage extending between the rotor and the stator from the high pressure side up to the low pressure side of the rotor, a return passage connecting the low pressure side of the rotor to the inlet. An intermediate passage opens into the relief passage between the high pressure side and the low pressure side of the rotor. A blocking member is configured to influence the flow through the intermediate passage.

    摘要: A well pump assembly includes a pump and a motor that contains a dielectric motor lubricant and a pressure equalizer containing a bellows. The bellows has an interior in fluid communication with the motor lubricant and an exterior immersed in well fluid. The bellows is axially extendable and contractible in response to a pressure differential between the well fluid and the motor lubricant. A tube has a lower end secured to a tube port in the pressure equalizer housing and an upper end secured to a lower end of the bellows. The tube has a center line that makes at least one curved flexible bend between the tube upper end and the tube lower end to enable the tube to flex as the bellows extends and contracts.

    摘要: A rotary blood pump includes a casing defining a pumping chamber. The pumping chamber has a blood inlet and a tangential blood outlet. One or more motor stators are provided outside of the pumping chamber. A rotatable impeller is within the pumping chamber and is adapted to cause blood entering the pumping chamber to move to the blood outlet. The impeller has one or more magnetic regions. The impeller is radially constrained in rotation by magnetic coupling to one or more motor stators and is axially constrained in rotation by one or more hydrodynamic thrust bearing surfaces on the impeller.
