Abstract

1412150 Centrifugal pumps GENERAL ELECTRIC CO 21 Dec 1972 [29 Dec 1971] 59072/72 Heading F1C A centrifugal pump comprises a shutter valve 50 located between the impeller 14 and the diffuser vanes 24 and movable between an inoperative position and an operative position, the valve comprising wall means 52 which leave the inlets to all the diffuser passages 26 open when the valve is in the inoperative position, and the wall means substantially completely closing the inlets to individual diffuser passages when the valve is in an operative position while leaving the inlets to the remaining diffuser passages substantially completely open. The wall means 52 is of cylindrical form and is movable axially either by a mechanical linkage or, as shown, by a piston 60. When the valve 50 is moved from a completely retracted position to a first operative position, it completely closes four of the twelve diffuser passages 26 while leaving completely open the eight remaining diffuser passages, each of which is in alignment with a corresponding slot 54, 56 or 58. When the valve 50 is moved further to a second operative position, the four passages aligned with the short slots 54 become closed so that four passages remain open. When the valve 50 is in a third operative position, the two passages aligned with the larger slots 56 are closed, so that only the two passages aligned with the longest slots 58 remain open.
