  • Patent number: 10072621
    Abstract: A circuit housing portion integrally molded above a lid main body portion has a bottom portion, which forms a vent space with the lid main body portion, and a vent hole, which extends through a portion between a protection space and an external space in the side portion. In a terminal, in which an intermediate portion is embedded in a bottom portion to extend between a fuel pump and a drive circuit through the bottom portion, an interface between the bottom portion and the intermediate portion is exposed to a protection space above the vent hole. A liquid-impermeable and gas-permeable membrane is mounted on an outer surface of the side portion to cover the vent hole to allow the fuel vapor to be discharged from the vent hole to the external space and to restrict liquid from entering the vent hole from the external space.

A pump or other fluid moving device circulates lubricant from the ESP motor to the lubricant pathways within the supporting frame structure, whereby the seawater cools the lubricant contained therein, which is then circulated back into the motor to assisting cooling the motor.

  • Patent number: 8696334
    Abstract: A submersible pumping system for downhole use in extracting fluids containing hydrocarbons from a well. In one embodiment, the pumping system comprises a rotary induction motor, a motor casing, one or more pump stages, and a cooling system. The rotary induction motor rotates a shaft about a longitudinal axis of rotation. The motor casing houses the rotary induction motor such that the rotary induction motor is held in fluid isolation from the fluid being extracted. The pump stages are attached to the shaft outside of the motor casing, and are configured to impart fluid being extracted from the well with an increased pressure. The cooling system is disposed at least partially within the motor casing, and transfers heat generated by operation of the rotary induction motor out of the motor casing.

  • Patent number: 8696327
    Abstract: 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.

  • Patent number: 8585374
    Abstract: An example fan assembly impeller moves air along a secondary flow path when driven by a motor. The motor also drives a fan rotor to move air along a primary flow path of the fan assembly. Air moving along the primary flow path moves in a first direction. Air moving along the secondary flow path moves in a second direction opposite the first direction. An example fan shroud communicates air used to cool a motor into a primary flow path of a fan assembly. The shroud communicates the air into the primary flow path so that the flow of air is at least partially aligned with air moving through the primary flow path of the fan assembly.
