The structure of gear pump is simpler than that of centrifugal pump, but the disassembly work is more laborious than that of centrifugal pumpThe components are heavy and should be installed with high precision. They are suspended on the beam and must be removedPay attention to safety. The components of the water pump can be disassembled in two parts, and now it is vertical axial flowTake the pump as an example to illustrate its disassembly process o]. disassembly of upper baseFirst remove the screws of the elastic coupling, loosen the screw guide connecting the motor and the base, and remove the motor. Support the pump rigid coupling with wooden blocks to prevent the pump shaft from falling, and then remove itThe cap nut on the transmission shaft, the connecting screw of the bearing gland and the engraved couplingLift it up to a certain height in the axial direction, then remove the cap of the rigid coupling, put out the wire, and remove the elastic couplingThe transmission shaft can be pulled out of the upper base through the coupling. Then remove the elastic coupling and roll itRemove the bearing from the transmission shaft with a special tool. So far, the upper base has been completely disassembled o2. Disassembly of lower pump bodyFirst remove the water inlet bell. Then use a special tool to lift the impeller nut at the lower end of the pumpOpen, the whole impeller can be removed. For the water pump with moving blade field, remove the inlet valveAfter the bell mouth, disassemble the moving blade ring and then disassemble the impeller.
