A kind of from drainage leakage-proof water pump, comprise the pump housing, impeller, pump shaft parts and seal arrangement, pump shaft parts comprise pump shaft and pump shaft supporting shell, pump shaft is bearing on pump shaft supporting shell by one group of bearing, impeller is arranged on the right-hand member of pump shaft, it is characterized in that: described pump shaft supporting shell comprises bearing construction section, housing linkage section and pump housing construction section, be fixedly connected with by housing linkage section between bearing construction section with pump housing construction section, pump shaft mounting hole is had at bearing construction section center, pump shaft mounting hole is arranged at intervals with two bearing mounting holes, pump shaft is inserted in pump shaft mounting hole, bearing is installed in bearing mounting hole, coaxial pump shaft mounting hole and Sealing mounting hole is had at the center of pump housing construction section, the aperture of Sealing mounting hole is greater than the aperture of pump shaft mounting hole, bearing construction section and pump housing construction section center disconnect, i.e. separated at bearing construction section and pump housing construction section of pump shaft mounting hole, bearing construction section, the internal surface of housing linkage section and pump housing construction section encloses drain chamber, housing linkage section has rhone, drain chamber is interlinked by rhone and the external world, seal arrangement is arranged in Sealing mounting hole, outer surface and the Sealing mounting hole of seal arrangement closely cooperate, internal surface and the pump shaft of seal arrangement closely cooperate.
Further, described seal arrangement is RUBBER O RunddichtringO.
Further, three rhones are had in the first-class spacing of housing linkage section.
Owing to changing the structure of pump shaft supporting shell, pump shaft supporting shell is provided with bearing construction section and pump housing construction section, bearing construction section and pump housing construction section separated, i.e. separated at bearing construction section and pump housing construction section of pump shaft mounting hole, bearing construction section, the internal surface of housing linkage section and pump housing construction section encloses drain chamber, housing linkage section has rhone, drain chamber is interlinked by rhone and the external world, the pump shaft supporting shell of this structure makes the water in the pump housing directly flow in drain chamber from the gap of bearing construction section and pump housing construction section, and then directly discharge from rhone, the water permeation stopped in the pump housing enters in the bearing construction section of pump shaft supporting shell, ensure that bearing completely and water segregation, slow down the corrosion rate of bearing, increase the working life of bearing, the bearing working time is long without the need to frequent stop production to overhaul, production time can not be incured loss through delay, and The present invention reduces a seal structures, only need simple rubber seal, without the need to the mechanical sealing element of manufacturing structure complexity, even if rubber seal wearing and tearing also can ensure the performance that prevents water penetration of water pump, save a large amount of cost of production and installation time to producer.
