Repair method

1. Maintenance of worn gear pump shaft

The wear of the shaft in the gear pump is mainly due to the frictional wear between the two ends of the shaft and the supporting rollers, which reduces the shaft diameter. If there is slight wear, the diameter of the shaft in this area can be increased by plating a layer of hard chromium to repair the shaft. If the shaft is severely worn, it should be remanufactured with 45 steel or 40cr steel. After rough and fine machining of the shaft blank, the bearing part should be heat treated with a hardness of hrc60-65, and then ground to ensure that the surface roughness ra of the bearing fitting part is not greater than 0.32 μ m; The allowable deviation for roundness and cylindricity of the shaft is 0.005mm; the mating part with the gear should be h7/h6, and the surface roughness ra should not exceed 0.63 μ m.
