1, Preparation work
Before disassembling the impeller of a deep well submersible pump, it is necessary to prepare necessary tools and protective equipment, such as gloves, goggles, etc. In addition, it is necessary to isolate the deep well submersible pump to ensure safety.
2, Remove the leaf cover
1. Determine the direction of the submersible pump outlet and disassemble it on the outlet side.
2. Use a wrench to remove the outlet shell nut.
3. Use a light hammer to strike the outlet housing or use a disassembly tool to lightly hammer it, causing the outlet housing to detach from the pump body.
4. Unscrew the impeller cover by hand and support the blade cover.
3, Disassemble the impeller
1. Hold the impeller with gloves and use a wrench to remove the fastening nut.
2. Use a balance block to push the impeller away from the shaft.
3. Check the wear and damage of the impeller and pump shaft. If necessary, new spare parts should be replaced.
During assembly, attention should be paid to the installation position and direction of the blade cover and impeller to ensure that the rotation direction of the impeller matches the design direction of the pump.
In short, the disassembly of the impeller of a deep well submersible pump requires careful operation. Following the above steps can successfully complete the disassembly and replacement of the impeller. If it is not necessary, it is recommended to avoid self repair operations as much as possible to avoid accidents.
