Abstract

PURPOSE: To prevent intrusion of slurry liquid, by fixing a shaft sleeve to a rotary main shaft for eliminating its loosening due to rverse rotation and also fitting an expeller between the suction end of the shaft sleeve and the boss end of an impeller.
CONSTITUTION: A shaft sleeve 5 is fixed to a main rotary shaft 3 to eliminate revolution to each other by folding projections 75 on the periphery of a washer 73 into concaves 55 on the end of the sleeve 3. The nearly cylindrical shaft sleeve 5 is fitted to the outside of the main rotary shaft 3 through sppropriate intervention of O-rings 51 and an expeller 2 is also fitted to the main shaft 3 between the suction side end 52 of the sleeve 5 and the boss side end 43 of an impeller 4 to prevent intrusion of slurry liquid. Water from a refill tube 17 is pressured by te expeller 2 and discharged by means of rear vanes 41 to inhibit intrusion of slurry liquid to the rotary shaft 3 and gland packing 16
