The bearing alloy of the plain bearing should be tightly coupled to the housing. Can not have shelling and cracks, pores and other defects; smooth surface. No scars and pits.
The maintenance of the centrifugal pump shall check the degree of wear, corrosion and erosion of each part after disassembly, and repair and replace it according to the specific conditions. (10,000 fan)
1) Repair of the stator parts. The pump body is thickness-measured and identified. The pump seat is also inspected. If cracks or other weldable casting defects are found in the unstressed part, repair according to JB/TQ369 "Pumping iron parts for pumps". Replace the worn sealing ring and the excessively large sealing ring, but carefully formulate the range of repairable dimensions to compensate for the worn parts of the corresponding parts to ensure the quality of the inspection.

2) Repair of the rotor parts. When the pump shaft is being repaired or replaced, it can be inspected if necessary. After the shaft is worn, it can be repaired by plating, spraying or brushing. After the shaft is worn, it can be appropriately increased according to the wear condition, but the maximum can only be increased by one level according to the standard size. When the structure and force are allowed, the keyway can be opened in the direction of 90 degrees or 120 degrees of the original keyway.
