Background
The application of the canned motor pump in chemical production is very wide, and the axial balancing force of the canned motor pump is realized by liquid pressure applied to the front side and the back side of an impeller or a balancing disc by a liquid medium. When the canned motor pump is operated, the hydraulic balance of the rotor parts needs to be kept. When the canned motor pump operates, the rotor is in a hydraulic balance position; that is, the rotor is located at the middle position of the front dead point and the rear dead point in the axial direction, so that the limiting parts (an impeller back opening ring, an inlet opening ring, a wear-resistant disc, a balance disc and the like) are not worn when the rotor moves in the axial direction due to the change of working conditions.
