Abstract
1,261,047. Centrifugal pumps. SIEMENS A. G. March 26, 1969 [March 26, 1968(2)], No. 15929/69. Heading F1C. In a centrifugal pump an inwardly-extending deflecting tongue 7, Fig. 1, is provided at the cutwater position so that during reverse idle rotation of the impeller 2 and termination of the water supply to the pump, the rotating ring of water remaining in the pump is deflected inwards to cause a port 9 of the ring to overlap the inlet port 4 to remove excess water therethrough when too much is present. Thus any additional water entering the pump at this time, e.g. by leaking through the various clearances, will be removed and the water column 10 in the outlet 3 will remain small thereby avoiding discharge through the outlet. The tongue may be straight, Fig. 3 (not shown), instead of curved as shown. A cavity (12), Figs. 2 and 4 (not shown), may be formed in the peripheral wall of the impeller chamber at a position immediately preceding the deflecting tongue in the direction of reverse rotation.
