Abstract

580,128. Centrifugal pumps. JOHNSON & SONS, Ltd., C. H., and DEARDEN, B. B. April 26, 1944, No. 7775. [Class 110 (i)] In a self-priming centrifugal pump having a water-lubricated bearing, the bearing is placed immediately behind the impeller so that it acts also as a water-seal. In the. arrangement shown, the bearing, comprising a rubber bush 18 with a metal backing, is mounted in a housing which forms part of the pump casing 11, into which the volute discharges, and which also contains packing 21 compressed by a gland 22 secured to a dished member 14 carried by the casing 11. The space between the member 14 and the casing 11 constitutes a reservoir for lubricating water fed from the pump casing 'through apertures 16 and communicating by means of a recess 25 and annular groove 26 with a groove. 27 in the periphery of a ring which separates the bearing 18 and the packing 21. The groove 27 communicates with the surfaces of the shaft through radial holes in the ring, so that water can be drawn into the bearing from the reservoir by means of a helical groove in the bearing bush ; this water cools the bearing and adds to the sealing of the packing 21 as well as lubricating the bearing. According to the Provisional Specification the inlet and outlet pipes rise from the pump 'housing and the former has a valve which closes automatically when the pump is at rest, so that the housing is always full of water.
