Too high temperature and pump dry running are the direct factors that cause demagnetization. The thrust bearing is wo, causing the inner rotor and the isolating sleeve friction magnetic pump to not run for a long time under certain working conditions, such as evacuation, cavitation, high temperature, etc. So we need to pay attention to avoid all occurrences of pump idling and too high temperature.

In addition, there are other degaussing reasons. If the flow is too small for a long Self-priming Surface Pumps Manufacturers time or the outlet valve is closed for too long during operation, the temperature of the inteal medium of the pump will increase, the lubrication of the pump's bearings will also become worse, and the temperature will be higher. The sleeve will be damaged after a long time. Do not pay attention to cleaning during maintenance, and iron filings are adsorbed The inner magnetism causes the isolation sleeve to wear through; 3.

The axial gap between the inner rotor and the isolation sleeve is too small, causing friction and loss of magnetism. 4. There are many reasons for too high temperature. The inteal cooling/lubrication pipeline will be blocked by dirt, which will cause the temperature of the inteal and exteal magnetic cylinders to rise rapidly, and there is a possibility of loss of magnetism; 2.2019-12-27 Magnetic pump demagnetization is an easy cause of damage.. 1

5. These chemical properties affect the selection of pump materials and pump types. At this time, the corresponding disassembly and inspection should be carried out, and the parts that cause the excessive clearance should be repaired or replaced. The problem of forward and reverse rotation: whether the user will use the reverse pumping when using the gear pump, if necessary, indicate it when selecting the type, and pay attention to issues such as machine seal selection.According to different chemical pump materials, the application fields are classified as follows:
