Magnetic pump working principle diagram

Magnetic pump is short for magnetic drive pump, simply, the working principle of magnetic pump is to use the working principle of permanent magnet coupling. Magnetic pump is mainly used in computer supercooling system, drinking fountains, water heaters pressure, car cooling system, humidifiers, and other bathroom products. Followed by detailed working principle of magnetic pump to understand the working principle of the magnetic pump it. Understand the working principle of the magnetic pump, first look at the composition of the magnetic pump it. Magnetic pump by the pump, magnetic actuator, the motor consists of three parts. The key components of the magnetic actuator consists of an outer magnetic rotor, an inner magnetic rotor and a non-magnetic isolation cover. When the motor drives the outer magnet rotor to rotate, the magnetic field can penetrate the air gap and the non-magnetic substance to drive the inner magnet rotor connected with the impeller to rotate synchronously to realize the powerless contact transmission and transform the dynamic seal into the static seal. As the pump shaft, the inner rotor is completely closed by the pump body and the isolation sleeve, thus completely solving the problems of running, running, dripping and leakage, and eliminating the leakage of flammable, explosive, toxic and harmful media through the pump seal in the refining and chemical industry Of the security risks, effectively guarantee the physical and mental health and safety of workers. The n pairs of magnets (n is even) according to the law arranged in the magnetic clutch, the outer rotor, so that the magnet part of each other to form a complete coupling of the magnetic system. When the inner and outer two poles are in opposite polarities, that is, the displacement angle between the two poles is Φ = 0, the magnetic energy of the magnetic system is the lowest. When the poles rotate to the same poles, that is, the displacement angle Φ = 2π / n, the magnetic system at this time the maximum magnetic energy. After removing the external force, due to the mutual exclusion of the magnetic poles of the magnetic system, the magnetic force will restore the magnet to the state with the lowest magnetic energy. So the magnet produces the movement, drives the magnetism rotor to rotate. Above we understand the working principle of the magnetic pump. There are many types of magnetic pumps, so we should pay attention to when purchasing the device flow, head, pressure, temperature and other parameters. Magnetic pump in the use of the process should pay attention to regular maintenance and cleaning, to keep clean.
