Abstract
7035. Day, W. March 21. Multi-stage centrifugal pumps; impeller blades; casings.-The impeller of a single or multi-stage pump has passages with constricted inlet and outlet openings, the outlet being smaller than the inlet. The casing has bridges 32 forming ports which are shut off from the impeller passages by the circumferential arcs 46 of the impeller as the latter rotates. The liquid is thereby compressed, and, as the impeller passage opens to the casing, the liquid rushes out. The pressure in the casing ports is reduced by the time the next impeller passage opens. The impellers are formed of two disks united by bridge-pieces 43 forming impeller passages between each pair. The impellers are attached to one end of an overhung shaft 3 by suitable arrangement of sleeves and nuts on the shaped shaft. The casing is made up in sections to facilitate assembling or dismantling the pump for inspection. The pump is supported in a trunnion bearing 5, the trunnion being grooved to receive a set-screw 18 which clamps the pump casing in any position required to give the discharge in any direction. In multi-stage pumps the impellers may be of different diameters.
