一、磁力泵的使用注意事项： （1）安装完毕后，用手转动联轴器检查有无碰擦现象。 （2）为防止杂物进人泵内，泵进口处设过滤器，过滤面积大于管路截面积的3一4倍。 （3）严禁空运转。 （4）扬程高的泵在出口管路上应装止回阀，以防突然停机的水锤破坏。 （5）开泵程序:开车前打开进口阀门，将泵内灌满须输送的液体;关闭出口阀;点动电扬机，检查泵的转向是否正确;泵启动后，出口阀应缓慢开启，待泵达到正常运行状态后，再将出口阀调到所需开度。试运转5~10min，如无异常，可投入运行。 停车程序:关闭出口阀门;切断电源;关闭进口，长期停机不用时，清洗泵内流道并切断电源。 二、维修要点和方法： （1）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）轴承损坏。CQB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）泵打不出液体。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，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。 值得注意的是，泵修了几遍查不出问题，应注意磁联轴器的工作是否正常。轴承、内磁转子和隔套在运行中都会产生热量，这将使工作温度升高，一方面使传递的功率下降，另一方面对输送易汽化液体的泵会产生很xxx烦。磁钢传递的功率随温度的升高是一条连续下降的曲线，通常，在磁钢工作极限温度以下，其传递能力的下降是可逆的，而在极限温度以上则是不可逆的，即磁钢冷却后，丧失的传递能力再也不能恢复。特殊情况下在磁力联轴器出现滑脱（失步）时，隔套中的涡流热量会急剧增长，温度急剧上升，如不及时处理，会引起磁钢退磁，使磁力联轴器失效。因此磁力泵应设计可靠的冷却系统。对不易汽化的介质，冷却循环系统一般由叶轮出口或泵出口引出液流，经轴承和磁传动部分回到吸人口，对易汽化的介质，应增加换热器或将液流引到泵外的贮罐，避免热量回到吸人口，对有固体杂质或铁磁性杂质的介质，应考虑过滤，对高温介质，则应考虑冷却，以保证磁力联轴器不超过工作极限温度。在考虑转速是否够时，先要检查电机本身的转速是否正常，可用转速计进行测量，在电机转速正常的情况下，可考虑是否会出现磁力联轴器的滑脱。 （4）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。 （5）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。

First, the use of magnetic pump Note: (1) After installation, check for hand grazing rotation coupling phenomenon. (2) To prevent debris into the pump, the pump inlet filter set, filter pipe cross-sectional area larger than 3 to 4 times. (3) non-air operation. (4) high lift pump should be installed in the export pipeline check valve to prevent the sudden shutdown of the water hammer damage. (5) Open pump procedures: If you drive, open the inlet valve, the pump filled with liquid to be delivered; close the exit valves; point electrokinetic Yang machine, check whether the correct steering pump; pump starts, valve should be slow to open until the pump reaches the normal operating state, then transferred to the required valve opening. Commissioning 5 ~ 10min, without exception, can be put into operation. Parking Procedure: Turn off the outlet valve; cut off the power supply; shut down imports, long-term parking when not in use, cleaning pump flow and cut off power supply. Second, maintenance elements and methods: (1) pump shaft break. CQB Magnetic Pump shaft material used is 99% alumina ceramic, mainly due to a broken pump, because the pump air operation, the bearings while the shaft is broken, dry grinding. Check to see when open pump bearings badly worn the main way to prevent broken pump is to avoid running the air pump. (2) bearing damage. CQB pump bearing material used is high-density carbon, in 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) playing no liquid pump. Play no liquid pump is the pump most likely to malfunction, the cause is greater. Should first check whether the pump suction line leaks place, check whether the air suction tube drained fluid volume infusion pump adequacy of inhalation tube is blocked with debris, the pump should also check whether the reverse ( especially looking from another motor or a power line after the overhaul), I should also note that the suction pump is too high a high degree. 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. It is noteworthy that the pump repair a few times and could find nothing wrong, should pay attention to the work of magnetic coupling is normal. Bearings, inner magnetic rotor and the sleeve will have heat in the operation, which will increase operating temperature, power passing down the one hand, the other hand, easily vaporized liquid delivery pump may be great trouble. Magnetic transmission power with increasing temperature is a continuous decline in the curve, usually the work of extreme temperature in the magnet below the decline of its transmission capacity is reversible, but above the limit temperature is irreversible, that is, magnetic cooling After the loss of transmission capacity can no longer be resumed. Exceptional circumstances arise in the magnetic coupling slip (step), the sleeve will be in the rapid growth of the eddy heat, the temperature rose sharply, if not in time, will cause magnet demagnetization, so that magnetic coupling failure. Therefore, a reliable magnetic pump cooling system should be designed. Vaporization of the medium on the difficult, cooling circulation system generally leads Impeller or pump flow through bearings and magnetic drive back to absorb some of the population, and easy to vaporization of the medium, should increase the heat exchanger or pump flow diverted to the outside the tank, to avoid the heat back to smoking population, there are solid impurities or iron on the magnetic impurities media filter should be considered, on medium heat, cooling should be considered to ensure that the work of magnetic coupling does not exceed the limit temperature. When considering the speed is enough to first check whether the normal speed motor itself can be used to measure the tachometer, the motor speed under normal circumstances, consider whether there will be magnetic coupling of the slip. (4) lack of lift. 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. (5) insufficient flow. Inadequate flow of the main causes are: damaged impeller, speed is not enough, head high, tube blockage with debris.
