International Classification:

F04D 29/22
F04D 29/20
F04D 29/18

Abstract:

A method and apparatus for a centrifugal pump according to which an annular retainer is positioned around a first end portion of a pump shaft, an open end portion of a compression cylinder is positioned around the first end portion of the pump shaft so that the pump shaft extends within an internal cavity of the compression cylinder, the compression cylinder is moved towards an annular groove formed in the first end portion of the pump shaft, and the annular retainer is sprung into the annular groove. In some embodiments, springing the annular retainer into the annular groove constrains one or more impellers and one or more annular spacers between the annular retainer and another annular retainer connected to the pump shaft.

International Classification:

F04D 13/10
F04D 1/00
E21B 43/12

Abstract:

An electric submersible pump (ESP) assembly. The ESP assembly comprises an inverted shroud separating a centrifugal ESP pump from a well casing, the ESP pump rotatably coupled to an ESP motor, the inverted shroud having an opening on an upstream terminal side, the upstream terminal side terminating at a head of the ESP motor, at least a portion of the ESP motor extending through the opening, the portion of the ESP motor extending through the opening exposed to formation fluid, and the opening sealed to the formation fluid at the head of the ESP motor tapered and wedged to the inverted shroud, wherein a centerline of the inverted shroud is offset from a centerline of the ESP motor.

International Classification:

F04D 29/046
E21B 43/12
F04D 13/10
F04D 29/54

Abstract:

An electrical submersible pump comprising a fallback bearing protection system, the system comprising: locking member; boot pivotally connected to shaft of electrical submersible pump adjacent to locking member, wherein the boot comprises a sloped outer wall capable of forming a fluid boundary thereby diverting fallback fluid away from uppermost bearing of electrical submersible pump; ridge disposed on the sloped outer wall of the boot. A method for protecting uppermost bearings of electrical submersible pump, the method comprising: operating the electrical submersible pump; removing power supply from electrical submersible pump; allowing fallback fluid to flow from a tubing disposed above electrical submersible pump into the electrical submersible pump thereby rotating fallback bearing protection system pivotally connected to shaft within electrical submersible pump; allowing the rotating fallback bearing protection system to create a fluid boundary capable of radially diverting the fallback fluid away from uppermost bearings of the electrical submersible pump.

Jason Eugene HILL - Catoosa OK, US

International Classification:

F04D 29/047
F16C 35/02

Abstract:

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.
