How to fix the magnetic pump pump shaft

Magnetic Pump Magnetic Pump Magnetic Pump is a kind of common and use range products compare with common Pump, Magnetic Pump bearing use of steel for high carbon chromium bearing steel, due to the high quality of bearing steel smelting after vacuum deaeration, electromagnetic stirring, oxide content is less, can accept larger contact compressive stress at the same time also can accept larger high tensile stress, after heat treatment, the axis of the raceway hardness of 58 62HRC。 If pump shaft magnetic pump has a crack or appearance has the heavy wear and tear, will affect the strength of the centrifugal pump shaft should be changed when the new shaft. Such as pump shaft slightly bent or slight wear, retractor, etc. , should stop to repair. So, magnetic pump pump shaft repair measures what? 1, magnetic pump shaft neck retractor and wear after repair with sliding bearing of the pump shaft journal, or bad smooth smooth oil into iron, sand, etc. And make the pump shaft journal scratch or grinding out of the trench, rubber at guide bearing journal wear, etc. , the ordinary steel, copper plating, stainless steel plating stop to repair, then the car or grinding method processed into standard diameter. 2, magnetic pump, 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, keyway magnetic pump repair such as slotting appearance 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 transmission power required a change in the new shaft. 4, magnetic pump shaft thread repair of pump shaft end thread damage lighter when available files to continue to use 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.
