Background

The magnetic pump is widely applied to industries such as chemical industry, petroleum, printing and dyeing, medicine, food, electroplating and the like, and is used for conveying liquids such as petroleum, chemical media and the like.

The magnetic pump is different from the traditional sealing pump, a motor shaft is not directly connected with a pump shaft, but the motor shaft drives an outer magnetic rotor to rotate, the outer magnetic rotor and an inner magnetic rotor are matched to drive the inner magnetic rotor to rotate through magnetic force, and the inner magnetic rotor drives the pump shaft to rotate, so that an impeller rotor on the pump shaft rotates to work. A sealing cavity formed by a spacer sleeve is arranged between an inner magnetic rotor and an outer magnetic rotor of the magnetic pump, a pump shaft and the inner magnetic rotor are sealed in the sealing cavity, so that liquid can be prevented from leaking from the end of the pump shaft to the outside, and the pump shaft and the inner magnetic rotor can be cooled, and therefore the excellent leakage-free characteristic can be obtained without adopting the traditional dynamic sealing for the pump shaft.
