Magnetic pump conveying media easy to crystallize

The utility model discloses a magnetic pump conveying media easy to crystallize. The magnetic pump comprises a shell, an impeller, a pump cover, a pump shaft, an inner magnetic rotor, a distance sleeve, an outer magnetic rotor, a motor and a liner plate arranged at one end of the motor. The outer magnetic rotor is fixedly connected with the pump shaft, and the inner magnetic rotor is fixedly connected with a motor shaft. A heat preservation support, an electric heating portion and an annular heat-conducting fin are arranged between the pump cover and the liner plate, the heat preservation support comprises an outer ring, an inner ring and a support end plate, the electric heating portion is arranged in the middle of the outer ring of the heat preservation support, the annular heat-conducting fin is arranged in a cylindrical cavity formed between the pump cover and the support end plate and connected with the pump cover, and the electric heating portion is connected with the annular heat-conducting fin through a wire. According to the magnetic pump conveying media easy to crystallize, the structure of the support is changed, the electric heating mechanism is added, the positions of the inner magnetic rotor and the outer magnetic rotor are changed, the direction of the distance sleeve is changed, the magnetic pump can be stopped and started at any time, the service life of the magnetic pump is prolonged, and use cost of a user is lowered.
