CENTRIFUGAL PUMP FOR HANDLING ABRASIVE-LADEN FLUID |
摘要 |
A centrifugal pump for handling abrasive-laden fluid is described. A centrifugal pump system for handling abrasive-laden fluid includes an impeller including an annular balance ring extending longitudinally on a top side of the impeller and an annular skirt extending longitudinally on a bottom side of the impeller, one of the annular balance ring, the annular skirt or a combination thereof having portions defining a plurality of apertures, wherein the plurality of apertures form an abrasive-media relief path that bypasses at least a portion of a clearance gap and merges with a primary working-fluid flow path. A centrifugal pump impeller includes a bottom shroud, an annular skirt extending longitudinally upstream from the bottom shroud, the annular skirt encircling a central hub, and the annular skirt having an aperture extending through a thickness of the annular skirt. |
