Abstract
884,115. Centrifugal pumps. KLEIN, SCHANZLIN & BECKER A.G. Sept. 2, 1960, No. 30392/60. Class 110 (1). In the multi-stage centrifugal pump shown, end thrust is balanced by a disc 8 mounted on the pump shaft within a chamber 1 supplied via a conduit 3 with pressure liquid from an intermediate stage of the pump. Axial displacement of the shaft due to a change of impeller thrust varies the gap between the disc 8 and a stationary partition to provide a variable leakage from the chamber 1 whereby the pressure in the chamber 1 varies in the sense to restore thrust equilibrium, in the known manner. According to the invention, the conduit 6 which returns the leakage from the chamber 1 to the pump inlet (or to a reservoir upstream of the inlet) includes a flow-sensing device 7 which adjusts a throttle 4 in the conduit 3, whereby the pressure in the chamber 1 is varied in the sense to assist in restoring thrust equilibrium. If the pumped liquid is hot, a cooler 5 may be provided either in the conduit 3 as shown or in the return conduit.
