The pump shaft bearing damage repair method is what

The pump shaft bearing of conventional shaft bearing selection of steel ( Including shaft, outer ring, roller ball) For the high carbon chromium bearing steel ( gcr15) 。 Because of the high quality of bearing steel smelting by vacuum deaeration, electromagnetic stirring, oxide content is less, in can contact under high compressive stress at the same time also can bear larger high tensile stress, after heat treatment, raceway hardness of 58 - axis 62hrc。 In the ring raceway hardness of 60 64 HRC, ball and roller hardness is 61 - 65hrc。 If the pump shaft surface cracks or heavy wear, when affect the strength of the centrifugal pump shaft should be replaced a new shaft. Such as the pump shaft bending or mild wear slightly, retractor, etc. , should be repaired. So, what methods of pump shaft repair? 1, pull hook shaft neck and wear after repair with sliding bearing of the pump shaft journal, due to bad lubrication or lubricating oil into iron, sand, etc. And make the pump shaft journal scratch or grinding out of the trench, rubber at guide bearing journal wear and so on, generally USES the plating, copper plating, stainless steel plating to repair, then the car or processed into standard diameter grinding method. 2, pump shaft bending repair of small-diameter pump shaft can be bent in place MATS of copper hammer knock alignment; Of larger diameter, without serious bending of pump shaft, screw corrector straightening. 3, shaft thread repair of pump shaft end thread damage lighter when available files continue to use the thread file repair after injury. If the injury is serious, the pump shaft end first small car, pressure on a bushing again, in the bushing on the screw thread; Also can use electricity, gas welding welding in thread on the pump shaft end, turning out the thread again. 4, keyway repair such as spline surface is rough, and the damage is not serious, available file repair the light. Such as damage to the heavier, but the old groove weld repairs, another new trough elsewhere, but for larger pump shaft must be replaced a new shaft transmission power.
