Why is the magnetic pump degaussed?

Magnetic pumps are widely used in chemical, acid, alkali, smelting, rare earth, pesticide, dye, medicine, paper, electroplating, electrolysis, pickling, radio, chemical foil, scientific research institutions, national defense industry and other industries to transport any concentration of acid, alkali, oil, rare and precious liquid, toxic liquid, volatile chemical medium, especially the magnetic pump for conveying leaking, flammable and explosive liquids is a commonly used pump. Degaussing is the reason why it is relatively easy to damage. Once demagnetization occurs, many people may be helpless, which may cause great losses to work and production. To avoid this, today let's take a brief look at why magnetic pumps are degaussed.

The high temperature of the pump and drying operation are the direct factors leading to degaussing. If the temperature is too high, there are many reasons. If the flow rate is too low or the outlet valve closes for too long during operation, the temperature of the medium in the pump will rise, the lubrication of the pump bearings will become worse, and the temperature will increase. The shaft sleeve will also be damaged after a long time.

Other reasons for degaussing:

1. The internal cooling and lubricating pipe is blocked by dirt, resulting in a rapid rise in the temperature of the internal and external magnetic cylinder, which may lead to loss of magnetization.

2. do not pay attention to cleaning during maintenance, and the iron filings are absorbed by the internal magnet, resulting in the wear of the isolation sleeve.

3. The wear of the thrust bearing leads to friction between the inner rotor and the spacer sleeve.

4. The axial clearance between the inner rotor and the isolation sleeve is too small, resulting in friction and loss of excitation.

5. The magnetic pump can not run for a long time under some working conditions, such as emptying, cavitation, high temperature, etc., so attention should be paid to avoid the occurrence of pump idling and excessive temperature.
