The structure of a gear pump is simpler than that of a centrifugal pump, but the disassembly work is more laborious and mainly zero

The components are heavy and require high installation accuracy. They are also suspended on the beam and must be disassembled

Attention must be paid to safety. The disassembly of the components of the water pump can be divided into two parts, now using vertical axial flow

Take the pump as an example to illustrate its disassembly process

]Dismantling of the upper base

Firstly, remove the screws of the elastic coupling, loosen the screws connecting the motor to the base, and remove the motor. Support the rigid coupling of the pumping unit with wooden blocks to prevent the pump shaft from falling down, and then remove it

The connecting screws of the cap nut and bearing gland on the transmission uranium are used to seal the coupling and tighten the transmission

Lift the shaft up to a certain height, then remove the joint cap and thread of the rigid coupling, and remove the elastic

The coupling can be used to extract the transmission shaft from the upper base. Remove the elastic coupling again and roll it

Remove the bearing from the transmission shaft using a special tool. At this point, all the upper machine seats have been disassembled

2. Removal of the lower pump body

First remove the water inlet bell mouth, and then use a special tool to lift the impeller at the lower end of the pump

Open it to remove the entire impeller. For the water pump equipped with a movable blade field, remove the water inlet valve

After the bell mouth is opened, disassemble the rotating blade ring and then disassemble the impeller.
