Overhaul chemical pump static sealing portion pump static sealing portion includes split joint surface, fittings, pipe flanges and other import and export combined with the bearing surface of the bearing cap box, lube oil system, such as the overhaul can not guarantee no leakage, also can not run the pump. These parts of the seal chemical pump, according to the media as long as selecting the right application of adhesives and gaskets that can guarantee no leakage. Now generally split adhesive used for bonding surface 703 South, 704 South. 4 impeller and rotor overhaul corrosion-resistant chemical pumps used mostly for single-stage or single-stage double suction impeller rotor. First check the appearance of the maintenance and clean impeller IH80-50-315 chemical pumps, either install a new impeller replacement parts, or cleaning the old impeller, back to do static balance were installed, if necessary, to do balancing. With the impeller and shaft using H / h IH80-50-200 chemical pumps, impeller key and keyway installation to properly contact. For part of the rotor shaft diameter is not greater than the permissible bending 0.013mm, for low speed shaft should be less than the maximum bending 0.07mm, high-speed shaft should be less than the maximum bending 0.04mm. Fitting sleeve portion and the shaft using H / h. For part of the rotor shaft, rear axle runout overhaul is not greater than 0.013mm, sleeve is not greater than 0.02mm, impeller mouth ring is not greater than 0.04mm IH80-50-250 chemical pumps, impeller face runout of not more than 0.23mm. Both ends of the shaft diameter is not greater than 0.02mm. But for more complex structure of the centrifugal pump, the above data is based on the standard condition of the pump varies. (1) single-stage pump seal arrangement of a single-stage pump seal arrangement shown in Figure 3. When the single-stage seal installation, you must ensure that dynamic and static ring parallel, bushings, journal sites should not have burrs and scratches. (2) Two-stage pump seal arrangement of the two-stage pump seal arrangement shown in Figure 4. Two-stage arrangement must be installed to ensure that the seal retaining ring dimensions and clearance, and a push into position, O-ring grooves can emerge, otherwise damage the mechanical seal sealing surface.
