摘要： A pump integral with an electric motor has an integral rotor and impeller assembly that rotates within a stator casing and is supported on hydrostatic radial and thrust bearings. The pump avoids having to provide external seals or friction type bearings. The unit has a stator with windings therein contained within a pump casing which has an axial liquid entry and a liquid outlet. An integral rotor and impeller assembly is mounted for rotation on a fixed axial shaft within the stator. The integral rotor and impeller assembly is positioned axially relative to the stator casing by hydrostatic thrust bearings where the pressure for the thrust bearing fluid is generated by radial ducts located within the integral rotor and impeller assembly.

摘要： A hydrostatic servo positioning system and hydrostatic thrust bearing for an integral motor/generator and pump/turbine provides recirculating seal liquid through the positioning system and bearings to permit minimal seal liquid flow. In an integral motor/generator and pump/turbine with a stator having windings integral with a casing, a rotor mounted for rotation on a fixed axial shaft within the stator, the rotor being integral with an impeller for liquid flow, the servo positioning system and thrust bearings comprise a passageway through the fixed shaft for seal liquid, a radial liquid duct in the rotor extending from the fixed axial shaft to a port opening in a peripheral surface of the rotor, the radial liquid duct having liquid connection to the passageway through the axial shaft to pressurize seal liquid centrifugally when the rotor rotates in the stator. First and second annular gaps between the peripheral surface of the rotor and the casing extend from both sides of the port opening into first and second thrust chambers between rotor thrust surfaces and the casing. First and second return orifices from the first and second thrust chambers lead to the radial liquid duct to provide first and second servo liquid flow loops.
