Assignee:

North American Marine Jet, Inc. - Benton AR

International Classification:

B63H 1111

US Classification:

440 41, 440 42

Abstract:

An apparatus and method are disclosed which allow a stream to be divided so that a portion continues to provide forward or reverse thrust while a portion is diverted to provide lateral thrust. The apparatus has a frame and a side diverter connected thereto. The side diverter is movable into and out of the path of a water stream from a jet propulsion unit to divert at least a portion of the water stream to provide lateral thrust. The apparatus preferably has two side diverters that may or may not be independently operable. The apparatus also preferably has one or more reverse diverters connected to the frame. The frame is preferably pivoted about two axes to move the side diverters into and out of the path of the water stream, and the reverse diverter preferably pivots about an axis that is perpendicular to these axes.

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.

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.

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.

International Classification:

F04D 29/06
F04D 13/10
E21B 43/12

Abstract:

A submersible well pump assembly has a pump, a motor, and a tubular pressure equalizer housing located between the pump and the motor. A rotatable drive shaft extends within the housing on the axis for driving the pump. A guide tube surrounds the drive shaft, defining an inner annulus between the drive shaft and the guide tube and an outer annulus between the housing and the guide tube. A well fluid inlet path admits well fluid into the outer annulus. A hub assembly is pivotally mounted to the guide tube. The hub assembly has a communication passage with having at least one lateral portion extending away the axis and a communication passage opening spaced from the axis and in fluid communication with the outer annulus. The hub assembly has a counterweight that rotates the communication passage opening to a point above the axis while the axis is horizontal.

F04D 13/08
F04D 1/06

Abstract:

An electrical submersible pump assembly has modules including a pump, a motor, and a seal section. A threaded connection between at least two of the modules has a first adapter and a second adapter. A collar rotatably carried and axially movable on one of the adapters is in threaded engagement with threads of the other adapter when the threaded connection is made up. First adapter lugs are spaced circumferentially apart from each other around the first adapter. Second adapter slots are spaced circumferentially apart from each other around the second adapter. The lugs slide into the slots while the adapters are brought together. Each of the lugs and each of the slots have side edges that are parallel with the axis. The side edges of the lugs abut the side edges of the slots to prevent rotation of the first and second adapters relative to each other.
