Abstract
997,111. Priming centrifugal pumps. R. BAUER. Aug. 26, 1963 [Sept. 10, 1962], No. 33731/63. Heading F1C. In a self-priming centrifugal pump for liquids, particularly for contaminated water or pulp, in which the liquid is fed by the impeller through a feed duct into an air release chamber, to which the discharge conduit is connected and which communicates through a return duct with the pump housing, the return duct opens tangentially into the pump housing at a point which is approximately opposite to the outlet from the pump housing to the feed duct and the return duct is inclined in the direction of rotation of the impeller towards the space in which the impeller blades move. When the pump is started, air-laden liquid is impelled through a feed duct 11 into an air release chamber 7 and gives rises to a liquid vortex 14 rotating in the direction of impeller rotation. The air bubbles collect at the centre of the vortex and rise towards the discharge connection 12 while the liquid flows back to the pump housing 6 through a return duct 13. The return duct 13 opens tangentially into the housing 6 in the first third of the periphery of the latter, which widens as a volute, the return duct being inclined in the direction of impeller rotation towards the space in which the impeller blades move. When the pump is shut down, a check valve in the suction pipe closes to retain sufficient liquid in the pump for the next start.
