Analysis of magnetic centrifugal pump failure analysis and solutions

(Asian Fluid Network) Magnetic centrifugal pump has a very significant role in the current industrial production process, its use not only greatly enhances our work efficiency, but also protects the safety of industrial production. However, magnetic centrifugal pumps, like other equipment, cannot be 100% efficient at work. We must deal with problems that may arise when working with magnetic centrifugal pumps. What are the magnetic centrifugal pump failures? Is there a corresponding solution?

Magnetic centrifugal pump failure analysis and solution

1. The pump shaft is broken: The material used for the pump shaft of the magnetic pump is 99% alumina ceramic.

2. Insufficient head of magnetic pump: The cause of this kind of failure is that there is air in the conveying medium, the impeller is damaged, the rotating speed is not enough, the proportion of the transported liquid is too large, and the flow rate is too large.

3. Insufficient flow of magnetic pump: The main cause of insufficient flow is damage to the impeller, insufficient rotation speed, excessive head lift, and blockage of debris in the pipe.

4. Damage to the magnetic pump bearing: The material used for the magnetic pump bearing is high-density carbon. If the pump is cut off or there are impurities in the pump, the bearing will be damaged. If the coaxiality between the inner and outer magnetic rotors of the cylindrical coupling is not guaranteed, it will directly affect the bearing life.

5, the magnetic pump can not play the liquid: the magnetic pump can not beat the liquid pump is the most likely fault, the reason is also more. First of all, check whether the suction pipe of the pump is leaky, check whether the air in the suction pipe is discharged, whether the amount of liquid poured in the pump is enough, whether the suction pipe is clogged with debris, and whether the pump should be reversed. It should be noted whether the suction height of the pump is too high. If you still cannot solve the above check, you can open the magnetic pump and check it.

Magnetic centrifugal pumps have the advantages of long service life, low working noise, high precision, and good shock resistance. With the rapid progress of China's industry, magnetic centrifugal pumps have emerged in many industries. Although there will be some conditions in the use process, but this does not affect the user's favorite of magnetic centrifugal pumps, I believe that with the support of modern science and technology and the wisdom of scientific researchers, the magnetic centrifugal pump failure will be better Improve.
