ABRASIVE HANDLING SUBMERSIBLE PUMP ASSEMBLY DIFFUSER

摘要

An abrasive handling submersible pump assembly diffuser is described. An electric submersible pump assembly stage comprises a rotatable impeller, and a co-axially mounted diffuser comprising a diffuser bowl, the diffuser bowl comprising a plurality of diffuser bowl wedges having a blunted pie-shape, each of the plurality of diffuser bowl wedges protruding axially from a diffuser bowl floor into a cavity between the rotatable impeller and the co-axially mounted diffuser such that each of the plurality of diffuser bowl wedges protrudes into a path of pumped solid-laden fluid, wherein the blunted pie-shaped wedges extend radially between an inner wall and an outer wall of the diffuser bowl and a thickness of the blunted pie-shaped wedges in a circumferential direction increases towards the outer wall.

主权项

1. A submersible pump assembly diffuser comprising:
an upthrust bowl separated from a downthrust bowl by a diffuser vane, wherein each of the upthrust bowl and the downthrust bowl comprise a floor, an inner wall extending axially from the floor around an inner diameter and an outer wall extending axially from the floor around an outer diameter; a first plurality of pie-shaped wedges arranged about the upthrust bowl floor, each of the first plurality of pie-shaped wedges protruding axially from the upthrust bowl floor and extending radially between the inner wall and the outer wall of the upthrust bowl, wherein a circumferential thickness of each of the first plurality of pie-shaped wedges increases from the inner wall to the outer wall of the upthrust bowl; and a second plurality of pie-shaped wedges arranged about the downthrust bowl floor, each of the second plurality of pie-shaped wedges protruding axially from the downthrust bowl floor and extending radially between the inner wall and the outer wall of the downthrust bowl, wherein a circumferential thickness of each of the second plurality of pie-shaped wedges increases from the inner wall to the outer wall of the downthrust bowl.
