1. Select the appropriate bearing material. All friction pairs in the bearing parts are made of high-quality silicon carbide. High-quality silicon carbide has high purity, silicon carbide content greater than 99%, ammonia corrosion resistance, high strength, elasticity, toughness and wear resistance, which greatly improves the bearing's anti-extrusion and impact ability, and its service life is other sliding Bearings (such as graphite) more than 10 times.
2. Select the proper thrust bearing clearance when installing the rotor. By fitting the rotor on the bearing body and pushing the rotor to one side, the maximum gap between the thrust bearing and toilet parts of the magnetic pump can be measured (the maximum axial movement j that the rotor can generate when the bearing is normal is 0.13 -0.15, adjust it to 0.3 ~ 0.5 mm. This gap range is conducive to the formation of the liquid film in the gap, reducing the friction between the two parts of the thrust bearing, and reducing the impact force when subjected to impact.
3. Optimize the operation in the process to minimize or avoid the large fluctuation of working conditions; extend the pumping cycle to 2 months to minimize the adverse effects of frequent pumping on the magnetic pump.
4. The improved magnetic pump pays attention to the process operation during operation, showing the inherent characteristics of the magnetic pump, and at the same time has good operating performance, maintenance-free for a long period of time, reliable operation, and the maintenance period reaches about one year. longer cycle operation of the equipment.
