Abstract
881,395. Centrifugal pumps. YOKOTO, H., and YOKOTO, S. Feb. 19, 1958, No. 5426/58. Class 110 (1). In the centrifugal pump shown, the firststage impeller 1 is of a low-head self-priming type and discharges by way of guide vanes 5a to a chamber 7 in which entrained air separates from the liquid. The separated air is discharged to atmosphere by way of a passage 8 and a vent 17, a filter (not shown) preventing clogging of the vent by dust or sand. The liquid passes by way of passages 9, 10 and 11 to the inlet 12 of the second-stage impeller 2 (which is of normal type), a weir 14 between the passage 11 and inlet 12 trapping sufficient liquid to prime the second stage. A sealing impeller 15 prevents the initial charge of priming liquid being removed from the passage 11 by the impeller 2. There may be more than two stages, and the stages are not necessarily on a common shaft or within a common casing. The second-stage inlet 12 may be located adjacent the casing wall, i.e. towards the coupling 20. The vent 17 may then be replaced by a slit in the position 23, between the shaft and the adjacent surface of the casing wall.
