摘要： A submersible well pump motor has features to prevent the carrier bearing from sliding axially along the stator due to thermal growth of the rotor. The rotor has a shaft and rotor sections spaced apart from each other. Carrier bearings are located between the rotor sections, each having an anti-rotation member that frictionally engages the inner diameter of the stator to prevent spinning of the carrier bearing. A deflectable thrust washer may be located between ends of the carrier bearing and the rotor sections. The thrust washer reduces in thickness in response to an axial thermal growth force due to axial thermal growth movement of the rotor sections and shaft. The thermal growth force is less than an amount of dislodging force required to cause the anti-rotation member to axially move relative to the stator. Rather than deflectable thrust washers, sacrificial thrust washers that dissolve prior to normal operation may be used.

摘要： A thrust module and a seal module for use in an electric submersible pump assembly is provided. The thrust module provides increased lubrication and heat dissipation while increasing sealing redundancies within the module. The thrust module includes a thrust bearing that absorbs thrust from the primary pump. A circulation pump assembly is coupled to the thrust bearing to circulate fluid through the thrust bearing and dissipate heat generated in the thrust bearing through a plurality of fins formed on an exterior surface of the circulation pump assembly. The seal module has labyrinth discs positioned within the seal module that inhibit fluid flow through the seal module. The seal module also includes check valves that release fluid from and allow fluid into the seal module at predetermined pressures. The sealing assembly is interposed between the thrust bearing and a primary pump of the electric submersible pump.

摘要： An electrical power assembly comprises a motor lead with individual metal sheathed conductors, a power cable with individual metal sheathed conductors and a splice connector for connecting each of the conductors. Each splice connector has a tubular metal fastener body with an upward facing shoulder at an upper end and a downward facing shoulder at a lower end. A metal nut assembly is fixed to one of the power cable conductors with a downward facing shoulder in metal-to-metal sealing engagement with the upward facing shoulder of the fastener body. A metal coupler fixed to one of the motor lead conductors with an upward facing shoulder in metal-to-metal sealing engagement with the downward facing shoulder of the fastener body. Contacts electrically connect one of the motor lead conductors to one of the power cable conductors within the fastener body. An elastomeric seal disposed between the nut assembly and the fastener body, has expansion relief voids operable to collapse and relieve stresses exerted by the seal when the seal undergoes thermal expansion.
