Problems solved by technology

The magnetic pump is equipped with an isolation sleeve between the inner magnetic rotor and the outer magnetic rotor to form a sealed cavity, which seals the main shaft and the inner magnetic rotor in the sealed cavity. Cooling with the inner magnetic rotor part, the rotor cavity formed by the spacer sleeve is connected to the pump cavity, and the medium in the high pressure area in the pump cavity is used to cool the rotor cavity, and the devices in the sealed cavity formed by the spacer sleeve are completely Immersed in the conveyed medium, the corrosiveness of the medium and the sand and other impurities in the medium will directly corrode and damage the inner cavity of the rotor, especially the bearing of the main shaft will be damaged, which will increase maintenance and affect production and normal work.
In addition, once the pumping occurs, the inner cavity of the rotor cannot be cooled by the medium, and the magnetic rotor will overheat, which will burn the equipment; it is not safe for high-pressure, toxic, flammable, and explosive media to enter the inner cavity of the isolation sleeve, especially Once the isolation sleeve is damaged, high-pressure, toxic, flammable and explosive media will easily leak or leak out of the pump

Abstract

The present invention relates to a high-performance magnetic drive pump. Said high-performance magnetic drive pump includes the following several portions: pump body, pump cover, pump shaft, blade wheel, coupling frame, internal magnetic rotor, external magnetic rotor, isolation sleeve, drive shaft and drive shaft bearing. Said invention also provides its working principle and concrete method.

Description

technical field [0001] The present invention relates to a magnetic pump. Background technique [0002] The magnetic pump is a pump in which the outer magnetic rotor and the inner magnetic rotor cooperate to drive the inner magnetic rotor to rotate through magnetic force, and the inner magnetic rotor drives the pump shaft to rotate, so that the impeller rotor on the pump shaft in the pump body rotates to work. The magnetic pump is provided with an isolation sleeve between the inner magnetic rotor and the outer magnetic rotor to form a sealed cavity, which seals the main shaft and the inner magnetic rotor in the sealed cavity. Cooling with the inner magnetic rotor part, the rotor cavity formed by the spacer is connected to the pump cavity, and the medium in the high pressure area in the pump cavity is used to cool the rotor cavity, and the devices in the sealed cavity formed by the spacer are completely Immersed in the conveyed medium, the corrosiveness of the medium and the ...
