  (1)磁力泵轴折断。CQB型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)磁力泵轴承损坏。CQB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)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。

Magnetic isolation pump troubleshooting (1) magnetic shaft broken. CQB-type magnetic materials used in the pump shaft is 99% alumina ceramic, mainly due to a broken pump, because pump air operation, the bearings and the shaft is broken, dry grinding. Disassemble the pump check to see pump bearings are worn to prevent a serious break of the main approach is to avoid running the air pump. (2) magnetic pump bearing damage. CQB magnetic pump bearing material used is high-density carbon, in case of pump or pump without water impurities, it will cause bearing damage. Inside and outside the cylindrical magnetic coupling between the coaxial rotor can not be guaranteed if requested, will directly affect the life of the bearing. (3) no magnetic pumped liquid. Magnetic pump pumps the liquid is not playing the most prone to failure, the reason is greater. Should first check the pump suction line whether there is leakage of the place to check whether the air suction tube discharge, magnetic fluid infusion pump adequacy, whether inhaled pipe clogged pump should also check out whether the reverse (especially after the motor replaced after maintenance or power lines), should also be noted on the pump suction height is too high. If the above checks can not be resolved, you can check the pump apart to see whether the broken shaft, you should also check the pump ring, quiet ring is intact, the possibility of a small amount of axial movement of the rotor. If the axial movement difficulties, to check whether the shaft with carbon bearings are too tight.
