  • Fiber optic measurement of parameters for downhole pump diffuser section
    Patent number: 8891076
    Abstract: A system for monitoring operating parameters for the pump section of an electrical submersible pump. The system includes an optic fiber associated with the pump section of an electrical submersible pump and having a sensor to detect at least one operating parameter within the pump section. The system also includes a signal analyzer operably associated with the optic fiber to receive an optical signal representative of the detected operating parameter.

  • Electrical shaft grounding brush assembly and holder for a submersible pump motor
    Patent number: 5988996
    Abstract: An electrical motor for a submersible well pump assembly has a brush for preventing arcing across the bearings. The motor has a housing and a stator stationarily mounted in the housing. A shaft extends through a cavity in the stator, the shaft carrying a rotor. Bearings are located at the base and head of the pump for stabilizing the shaft in the housing. A brush is stationarily carried by the housing in electrical common with the stator in the housing. The brush is also in sliding engagement with the shaft. The brush is located near one of the ends of the housing to reduce arcing across the bearing because of voltage differential between the shaft and the stator.
