Shaft inspection and replacement to submersible dredge pump


Submersible dredge pump, also known as submersible sediment pump, submersible mud pump, submersible sand pump, submersible suction pump, submersible pump, underwater dredging pump, etc., China Do Pump is a manufacturer of sand pump. dredge pump, electric submersible sand pump and hydraulic submersible dredge pump with relative dredging equipment.

Check and replace the pump shaft and shaft sleeve of the submersible sediment pump. If you use a submersible sediment pump, it is a problem that will inevitably be encountered. Because the knowledge of this problem is not popular enough, it often troubles everyone, so I hope we can gradually Complete the work of popularizing the knowledge of submersible sediment pumps.


1.The pump shaft of the submersible sediment pump should not have defects such as corrosion and cracks. Non-destructive flaw detection can be performed when necessary to repair or replace the pump shaft, and check for cracks.


2.The surface roughness of the pump shaft shaft diameter of the submersible sediment pump is 1.6 at the rolling bearing and 0.8 at the sliding bearing.


3.Using the shaft diameter at the two bearings as the fulcrum, use a dial indicator to check the radial runout of the shaft diameter of the assembled impeller, shaft sleeve and coupling, etc.


4.The offset of the center of the keyway to the centerline of the shaft diameter of the submersible sand pump should not be greater than 0.06mm, and the skew is not greater than 0.03mm / 100mm.


5.After the shaft diameter of the submersible sand pump is worn, it can be repaired by electroplating, basin plating, coating and other methods.


6.The material of the shaft sleeve should conform to the drawing, cracks of the submersible sand pump shaft sleeve are not allowed, and the outer round surface is not allowed to have casting defects such as trachoma, pores, and looseness.


7.The submersible sand pump shaft sleeve and shaft use H8 / h8 or H9 / h9.


Of course, the inspection and replacement of the submersible pumps and shaft sleeves of our submersible sediment pumps are still more complicated. When you really cannot replace them, you must ask the experts of the relevant submersible pumps to help solve the dilemma we face. The inspection and replacement of the pump shaft and sleeve were completed successfully.
