ã€Asia Pump Network News】 Fluorine plastic 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. 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 = 2Ï€ / 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. Fluorine plastic magnetic pump working principle and precautions Magnet pump use precautions 1. Prevent particles from entering the magnetic pump (1) Do not allow ferromagnetic impurities, particles into the magnetic clutch and bearing friction. (2) After conveying the easily crystallized or precipitated medium, it should be rinsed promptly (after the pump is stopped, pour water into the pump chamber and discharge clean after running 1min) to ensure the service life of the sliding bearing. (3) When transporting media containing solid particles, filter at the inlet of the pump tube. 2. To prevent the magnetic pump demagnetization (1) magnetic moment can not be designed too small. (2) It should be run under the specified temperature, the medium temperature is strictly not allowed. A platinum resistance temperature sensor can be installed on the outer surface of the magnetic pump isolation sleeve to detect the temperature rise in the annulus area so as to alarm or stop when the temperature exceeds the limit. 3. To prevent the magnetic pump dry friction (1) is strictly forbidden. (2) It is forbidden to use the medium to empty. (3) in the case of the outlet valve is closed, the magnetic pump continuous operation time shall not exceed 2min, to prevent the magnetic actuator overheating and failure.
