To master! Reduce the cost of maintenance and repair skills - magnetic pump

the introduction of magnetic pump, because the pump shaft by pump body and the magnetic rotor and isolation sets of completely closed, completely solve the 'run, run, drip, leak problem, eliminates harmful medium oil refining chemical industry. The safe hidden trouble that caused by pump seal leakage to ensure the physical and mental health of workers and production safety.

as magnetic pump users, in addition to learn the proper use of magnetic pump, you should also master the necessary magnetic pump maintenance skills. Next, we will list some of the common magnetic pump failure.

1, the head is insufficient, the main reasons of the lack of magnetic force pump transmission medium is air, the impeller is damaged, speed is not enough, the proportion of conveying liquid is too big, too much traffic, and so on.

2, flow is insufficient, the main reasons of the lack of magnetic pump flow impeller is damaged, speed, high lift and tube with debris.

3, bearing damage: magnetic pump bearing material made from carbon. If you have any impurities, shut down the pump or pump will damage the bearings. In addition, within the cylindrical shaft coupling of magnetic pump, between the outer magnetic rotor magnetic rotor if cannot ensure alignment requirements, will directly affect the service life of the magnetic water pump bearing.

4, shaft fracture: magnetic pump pump shaft material of 99% alumina ceramics, which can lead to magnetic pump shaft fracture. The reason is that the pump dry, dry bearings, shaft and twisted. Removing the pump, it can be seen that the bearing has been wear and tear, prevent damage of pump is the main method to avoid pump idling.

5, not into liquid: when magnetic pump can't into the liquid, first check whether water pump suction pipe leak, check whether the air inside the suction pipe has been exhausted, and injected into the liquid volume of magnetic pump. Whether enough, if you have any impurities in the suction pipe, please check whether the pump is inverted ( Especially after the replacement of motor or to repair the power cord) And pay attention to the pump suction height is too high.

if the check is still unable to solve, you can open it and check the pump shaft is damaged. Also check the pump ring and static ring are intact, whether the whole rotor can be a small amount of movement, and whether magnetic pump axial movement. To check whether carbon bearing and the pump shaft connection strong.
