More Information
Summary:An oil field pump is installed within a pipe that connects to an oil field, and feeds accumulated extraction oil in a predetermined direction, the oil field pump including a rotor formed with an internal flow path for the extraction oil, a stator mounted on the outer circumference of the rotor, a thrust bearing that supports the axial weight of the rotor and the stator, and a supply pipe that supplies a portion of the extraction oil from the center side in the rotational direction of the flow path to the thrust bearing.
