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:

A diffuser subassembly for use in downhole submersible pump assemblies includes a bearing set for supporting a drive shaft of the pump assemblies. The bearing set includes a sleeve for supporting the drive shaft in upward, downward and radial directions. The sleeve includes a central flange captured axially between a pair of bushings fixed to a diffuser body. Axial loads from the drive shaft may be transferred through the central flange of the sleeve to one or the other of the bushings into the diffuser body to accommodate upward and downward thrust forces. The bushings may be keyed to discourage rotational motion with respect to the diffuser body.

International Classification:

E21B 43/12
F04D 13/10
F04D 29/70

Abstract:

A self-orienting gas evading intake for a submersible pump provides an efficient, reliable and inexpensive system for pumping a downhole fluid to a surface. An intake section of a submersible pumping system may comprise a blocker sleeve disposed between an external housing and an eccentric intake. The intake section may be self-orienting such that a gas component of the fluid ascends the borehole to separate from a liquid component of the fluid. Actuation of a blocker sleeve exposes one or more ports of the external housing while blocking one or more other ports. The liquid component is drawn into the intake section through an exposed port and through one or more openings of the eccentric intake. The liquid component may then be drawn into the pump. As the liquid component comprises non-detrimental amounts, if any, of a gas component, the pump operates efficiently and effectively.

International Classification:

F04D 29/44
E21B 43/12
F04D 1/06
F04D 29/62

Abstract:

An electric pump may include a stack of diffusers including a first diffuser and a second diffuser. The first diffuser includes a recess therein defining an inner recess surface substantially circumscribing a primary diffuser axis. The second diffuser includes a lip projecting into the recess of the first diffuser. In response to a differential torque applied to the first and second diffusers about the primary diffuser axis, the lip of the second diffuser may engage the inner recess surface of the first diffuser, and thereby prevent relative rotation of the diffusers with respect to one another. An outer perimeter surface of the lip and the inner recess surface may define polygonal shapes or other non-circular profiles.
