The necessary conditions to be removed when the pump needs to be disassembled to replace the pump impeller that has reached the end of its life:
1. When transporting high-concentration slurry, the selected long distance is abruptly shortened, and the emission reduction distance is shortened to half. It is necessary to disassemble the pump to check whether the blade is worn and scrapped.
2. The pump under the pump pumps the slurry countercurrently and sprays out from one point selectively. The pump needs to be dismantled in time to detect and replace worn parts.
3. During normal slurry discharge operation, when there is an abnormal noise or stuck pump, when the pump blade emits an irregular roar, immediately stop the pump to check the rotor and the pump body impeller.
When the above three conditions are met, it is necessary to immediately check the operation of the impeller, which is a prerequisite for replacing the impeller. There are two installation methods when replacing the submersible sand suction pump impeller, slot key type and shaft head top buckle type, which can be removed by turning the impeller in reverse and rotating in the reverse direction. It is found that one of the above phenomena can be quickly with the Ziquan sand suction pump manufacturer Consult with spare parts and prepare in advance to prevent affecting the later production and construction.
