摘要： The present invention provides a rotary blood pump with both an attractive magnetic axial bearing and a hydrodynamic bearing. In one embodiment according to the present invention, a rotary pump includes an impeller assembly supported within a pump housing assembly by a magnetic axial bearing and a hydrodynamic bearing. The magnetic axial bearing includes at least two magnets oriented to attract each other. One magnet is positioned in the spindle of the pump housing while the other is disposed within the rotor assembly, proximate to the spindle. In this respect, the two magnets create an attractive axial force that at least partially maintains the relative axial position of the rotor assembly. The hydrodynamic bearing is formed between sloping surfaces that form tight clearances below the rotor assembly.

摘要： A press-fit thrust bearing system and apparatus. A press-fit thrust bearing for an electric submersible pump includes a protruding band extending around a midsection of a bushing, the protruding band extending inward towards a drive shaft, outward towards a diffuser, or both. When extending outwardly, the band is press-fit into the diffuser to prevent dislodgment of the bushing. A non-rotating guide sleeve extends around the bushing above the protruding band, the guide sleeve interlocking with the protruding band to prevent rotation of the bushing. The guide sleeve includes a projection, the protruding band has a channel and the projection mates with the channel to form the interlock. A pair of flanged, rotatable bearing sleeves extend inwards of the single bushing and are keyed to the drive shaft. The top and bottom faces of the bushing serve as thrust handling surfaces.

摘要： In a sliding bearing, load carrying capacity and bearing rigidity is increased without increasing a size of the bearing and the pressure of the fluid. The sliding bearing comprises a cylindrical-shaped sleeve supporting a rotatable shaft via fluid, and hydrostatic pressure pockets provided in the inner periphery of the sleeve. The hydrostatic pressure pockets constitute a plurality of rows of circumferentially disposed hydrostatic pressure pockets via orifices. At least one of the hydrostatic pressure pocket rows is arranged adjacently to each of both end portions of the inner periphery of the sleeve. And a circular cylindrical inner peripheral surface region without the hydrostatic pressure pockets is provided at a center portion of the sleeve. A width of the circular cylindrical inner peripheral surface region provided in the axial direction of the shaft is made wider than a sum of widths of the hydrostatic pressure pocket rows.

摘要： An axial-flow blood pump for pumping blood includes a substantially cylindrical outer enclosure. A tubular housing concentric with and located within the outer enclosure has at one end an inlet and at an opposite end an outlet. A motor stator is concentric with and located between the outer enclosure and the tubular housing. An impeller is concentric with and located within the tubular housing. The impeller is suspended in operation by a combination of passive magnetic forces between magnets within the impeller or magnetized regions of the impeller and the motor stator and hydrodynamic thrust forces generated as blood flows between the tubular housing and a plurality of hydrodynamic thrust bearing surfaces located on the impeller. A volute may be in fluid-tight connection with the outlet of the tubular housing for receiving blood in the axial direction and directing blood in a direction normal to the axial direction. The volute has a flow-improving member extending axially from the volute and into and coaxially with the tubular housing.

摘要： An apparatus for maintaining the operation of a geothermal production pump having one or more impellers and a vertical line shaft for driving the impellers, includes a liquid buffer for isolating a discharge column through which pumped geothermal fluid including non-condensable gases flows from a lubrication column through which flows oil for lubricating one or more bearings of the line shaft, the liquid buffer being interposed between the discharge column and an outlet of the lubrication column to prevent infiltration of the non-condensable gases into the lubrication column. The liquid buffer includes an upper oil receiving section facing the lubrication column outlet and a lower securing element related to the upper oil receiving section. A lowermost bearing is a thrust bearing, and a bowl in which the cup structure and the thrust bearing are housed is in fluid communication with a further bowl in which is housed an uppermost impeller.
