Abstract

1435545 Helico-centrifugal pumps CHANDLER EVANS Inc 3 Aug 1973 [3 Aug 1972] 37014/73 Heading F1C A control member 14 rotatable with a substantially helical impeller blade 10 is formed with a substantially helical slot 26 into which the blade is screwable whereby the effective working area of the blade is changed. The blade 10 is integral with or fixed to the impeller shaft 12 while the control member or hub 14 is connected to the shaft through a torsion spring 28. The spring tends to move the hub 14 towards the chain-line position in opposition to the dynamic and hydraulic forces tending to move it into the full-line position, whereby it assumes an equilibrium position in which the flow area between the hub and a shroud 16 is in accordance with the flow conditions. The positioning of the hub 14 may instead be effected by a servo actuator controlled by the flow-rate.
