Abstract
431,886. Stuffing - box substitutes. PULSOMETER ENGINEERING CO., Ltd., and GIBBS, B. H., Nine Elms Iron Works, Reading, Berkshire. March 24, 1934, No. 9324. [Class122 (v)] A leakage - collecting chamber 3 is arranged about the shaft 5 of a submersible pump 1 driven by an electric motor 2. A labyrinth or other packing 4 is arranged between the pump and the chamber 3, and may be protected from sand by wire gauze 7. Leakage is discharged from the chamber 3 through a pipe 9, with a check valve 10, by an impeller 8 on the shaft 5. The boss 11 of the impeller is elongated and hollow, and forms a labyrinth packing with a stationary sleeve 12. Further packing 15 is arranged below the sleeve. A second leakage-collecting chamber 14 is arranged below the packing 15. The shaft 5 is surrounded by a stationary sleeve 16 in the chamber 14 and entry of leakage into the sleeve is prevented by a thrower 17 on the shaft. A float 18 in the chamber operates a bell or other signal to indicate the collection of leakage.
