日常维护和检修磁力泵的方法：磁力泵的五项维护说明： 　　1、轴折断： 　　磁力泵的泵轴采用的材料是99%的氧化铝瓷，泵轴折断的主要原因是，因为泵空运转，轴承干磨而将轴扭断。拆开泵检查时可看到轴承已磨损严重预防泵折断的主要办法是避免泵的空运转。 　　2、轴承损坏： 　　磁力泵的轴承采用的材料是高密度碳，如遇泵断水或泵内有杂质，就会造成轴承的损坏。圆筒形联轴器内外磁转子间的同轴度要求若得不到保证，也会直接影响轴承的寿命。 　　3、扬程不足： 　　造成这种故障的原因有:输送介质内有空气，叶轮损坏，转速不够，输送液体的比重过大，流量过大。 　　4、流量不足： 　　造成流量不足的主要原因有:叶轮损坏，转速不够，扬程过高，管内有杂物堵塞等 　　5、磁力泵打不出液体： 　　磁力泵打不出液体是泵最易出现的故障，其原因也较多。首先应检查泵的吸入管路是否有漏气的地方，检查吸入管内空气是否排出，磁力泵内灌注的液体量是否足够，吸人管内是否有杂物堵塞，还应查一查泵是否反转(尤其是在换过电机后或供电线路检修过后)，还应注意泵的吸上高度是否太高。通过以上检查若仍不能解决，可将泵拆开检查，看泵轴是否折断，还应检查泵的动环、静环是否完好，整个转子可否少量轴向移动。若轴向移动困难，可检查炭轴承是否与泵轴结合的过于紧密。

Routine maintenance and repair method of magnetic pump: magnetic pump five maintenance instructions: 1, shaft fracture: Magnetic materials used in the pump shaft is 99% alumina ceramic, mainly due to a broken pump, because the pump air operation, the bearings while the shaft is broken, dry grinding. Disassemble the pump check to see when the pump bearings are worn to prevent a serious way is to avoid breaking the main air pump running. 2, bearing damage: Magnetic pump bearings used in high-density carbon materials, such as the case of pump or pump without water impurities, it will cause bearing damage. Cylindrical external magnetic coupling between the coaxial rotor can not be guaranteed if requested, will directly affect the bearing life. 3, lift less than: Cause of this failure reasons: within the transport medium of air, impeller damage, speed is not enough, the large proportion of transmission fluid, fluid overload. 4, flow rate less than: Inadequate flow of the main causes are: damaged impeller, speed is not enough, head high, tube blockage with debris 5, magnetic play no liquid pump: Magnetic pumps play no liquid is most likely to pump malfunction, which causes greater. Should first check whether the pump suction line leaks place, check whether the air suction pipe discharges, magnetic fluid volume infusion pump is adequate, whether inhaled debris blocked tube, the pump should also check whether the reverse (especially after looking from another motor or supply line after maintenance), should also be noted on the pump suction is too high. Check if the above still does not resolve, you can check the pump apart to see whether the broken shaft, but also check the pump ring, stationary ring is intact, the possibility of a small amount of rotor axial movement. If the axial movement difficulties, you can check whether the carbon bearing too closely integrated with the shaft.
