Abstract

874,531. Centrifugal pump impellers. A.E.I.- HOTPOINT Ltd. Dec. 31, 1959, No. 44451/59. Class 110 (1). A centrifugal pump impeller 3 comprises a hub 19 to which at least one blade is affixed, the blade(s) 18, at rest being inclined forwardly to the direction of intended rotation of the impeller from a plane containing the impeller axis and the location of the blade root, the blade(s) being so mounted or made of flexible material that as the speed of rotation of the impeller increases from zero to maximum the blade(s) 18 changes from its forwardly inclined position through the radial position II to a backwardly inclined position V. The pump impeller 3 rotates in a casing 1 formed by a removable cover 6 having an integral outlet 5 and a body member 7, having an integral inlet 9, said body member containing shaft bearings 11 and lubricant impregnated felt washers 12. At the position of rest the blades 18, which may be moulded integrally with the hub in indiarubber, are concave with respect to the direction of rotation and when running at relatively low speed the blades are fully extended, as at II. As the speed increases the pumping efficiency diminishes and the power required to drive the impeller increases more slowly than with fixed or rigid blades. The blades may bend against, and so be supported by projections 21 in the hub at the highest speeds. The pump is intended for spin driers wherein the maximum quantity of water to be pumped out occurs soon after spinning starts.
