Abstract

687,514. Centrifugal pumps. OAKLEY, J. L. D. (Fairbanks, Morse & Co.). Aug. 15, 1950, No. 20261/50. Class 110(i) A centrifugal pump impeller comprises a body provided with at least one passage of generally helical form and of a length greater than one complete turn, extending between an axially positioned inlet and an outlet in the periphery of the body. In a centrifugal pump suitable for handling sewage or other fluids containing solid matter, the impeller 20, Fig. 6, which is preferably of one piece construction, has a suction inlet 22 leading into a passage 35 which extends in a generally helical manner, with increasing radius, until it opens into the impeller periphery as at 38, and continuing until the bottom surface 39 of the passage merges into the peripheral surface. Instead of being circular as shown, the cross-section of the passage 35 may be elliptical or hexagonal, and its area may vary along the passage. There may be two helical passages, affording an inlet at each side of the impeller. The impeller may be balanced by coring- out, as at 45. Alternatively, a counterweight 47, Figs. 9 and 10, can be used. It is shaped to act as an impeller for ejecting matter tending to leak into a chamber 48 through a gap 49.
