    摘要： An electrical submersible pump motor has motor oil flowing through external circulation tubes for cooling the motor. A substantial portion of the exterior of each tube is submerged in and exposed to wellbore fluid. Heat is transferred from the motor to the motor oil, and then circulated through the external circulation tubes to conduct heat to the wellbore fluid. Internal or external motor oil pumps may be used to propel the motor oil through the circulation tubes. Guards or baffles may be used to protect the circulation tubes and to influence the flow of production fluid over the circulation tubes.

    摘要： A floating ring bearing for an electric submersible pump (ESP) assembly disposable within a cased wellbore and a method to assemble the same are disclosed. The ESP assembly includes a motor, a pump, and a shaft coupling the pump to the pump motor. One or more floating ring bearings are disposed within the motor and the pump, each floating ring bearing circumscribing the shaft to radially support the shaft. A floating ring is disposed within each floating ring bearing. The floating ring circumscribes the shaft so that the floating ring rotates about the shaft in response to rotation of the shaft.

    摘要： An electric submersible well pump assembly includes a rotary pump and an electrical motor. The motor has a motor housing filled with a dielectric lubricant. A stator formed of a stack of stator disks with a stator bore is stationarily mounted within the motor housing. A motor shaft extends through the bore. A rotor is mounted to the shaft for rotating the shaft and has a stack of rotor disks. Axially spaced-apart radial stabilizing portions along the rotor have outer peripheries that are greater in outer diameter than remaining portions of the rotor. The outer peripheries of the stabilizing portions rotate with the rotor and are closely spaced to the inner diameter of the stator to radially stabilize the shaft.
