Reasons for demagnetization of magnetic pumps

　　Magnetic pump demagnetization, that is, magnetic pump in the operation of the process of magnetic force gradually weakened or completely disappeared phenomenon, the reasons can be summarized in a number of aspects. The following are some of the main reasons:

　　1. Magnetic pump overload or rotor jamming

　　Overload: When the magnetic pump is subjected to excessive load during operation, the master and slave parts of the magnetic actuator may slip off automatically, resulting in the slave parts not running in synchronization with the master parts, thus causing demagnetization.

　　Rotor jamming: If the rotor of the magnetic pump cannot rotate normally due to failure or jamming of foreign objects, it will likewise lead to the failure of the magnetic actuator, which in turn will trigger demagnetization.

　　2. Design and installation problems

　　Unreasonable design: If the magnetic torque design is too small to meet the actual operating requirements, the pump may be demagnetized due to insufficient magnetic force after a long period of operation.

　　Improper installation: such as mismatched specifications of the outlet pipeline, improper installation position of the pump, etc., may affect the normal operation of the magnetic pump and increase the risk of demagnetization.

　　3. Medium and working condition changes

　　Nature of the medium: the transport medium has the nature of volatile gasification, or the medium contains impurities, may affect the stability of the operation of the magnetic pump, resulting in demagnetization.

　　Changes in operating conditions: fluctuations in temperature, pressure and other operating parameters may cause changes in the operating state of the magnetic pump, thus triggering demagnetization.

　　4. Improper maintenance and repair

　　Incomplete cleaning: impurities blocking the ventilation ducts inside the magnetic pump, or lack of attention to cleaning and sanitation during maintenance, leaving iron filings and other foreign objects, may lead to a rise in the temperature of the internal and external magnetic cylinder of the magnetic pump, and the magnetic force gradually fades.

　　Wear and damage: the thrust bearing, slide bearing and other parts inside the magnetic pump are not operated scientifically for a long time, resulting in wear and tear, and the friction between the inner magnetic rotor and the isolation sleeve increases, which in turn triggers demagnetization.

　　5. Other factors

　　Improper operation: such as the operator's responsibility is not in place, in the operation of the magnetic pump can not keep abreast of the liquid level of the storage tank, so that the pump pumping produces slippery magnetism.

　　Material aging: permanent magnets and other key materials in the magnetic pump may be aging with the use of time, resulting in weakened magnetic force.

　　In summary, the causes of magnetic pump demagnetization are manifold, including overload, design and installation problems, changes in media and working conditions, improper maintenance and repair, and other factors. In order to avoid the occurrence of magnetic pump demagnetization, you need to regularly check and maintain the magnetic pump to ensure that it is in good operating condition; at the same time, you also need to pay attention to the operation specifications and safety production, to avoid malfunction caused by improper operation.
