Problems solved by technology

In actual operation, due to various accidental factors, the film-forming state of the lubricating film will be unstable. At this time, there may be rubbing on the sealing end face. Although slight rubbing will not immediately cause seal failure, it will It may also lead to further deterioration of the film-forming state and eventually cause failure

Embodiment Construction

[0009] The present invention will be described in more detail below in conjunction with the accompanying drawings.

[0010] Such as figure 1 As shown, the mechanical seal ring with magnetic ring includes the moving ring part and the corresponding static ring part, among which figure 1 The moving ring subsection shown in (a) includes a cylindrical ring-shaped sealing moving ring 1 and a cylindrical ring-shaped first magnetic inner ring 2 in the sealing moving ring 1, the outer ring surface of the first magnetic inner ring 2 and the sealing The inner ring surface of the moving ring 1 is embedded in an interference manner, and the end face of the first magnetic inner ring 2 on the sealing end face side is flush with or lower than the sealing end face of the sealing moving ring 1; and figure 1 The static ring subsection shown in (b) includes a cylindrical annular sealing static ring 3 and a cylindrical second magnetic inner ring 4 in the sealing static ring 3, the outer ring surf...

Abstract

The invention relates to a mechanical seal ring with a magnetic ring. A first magnetic inner ring and a second magnetic inner ring in a moving ring part and a static ring part matched with the moving ring part have the same magnetism on the opposite end faces at a sealed end face side, the seal rigidity is increased by the repulsive force of the two end faces in non-contacting mechanical face seal, the disadvantage of seal failure caused by rubbing of seal faces is avoided, the structure is simple, and the use is convenient.

Description

technical field [0001] The invention relates to the technical field of mechanical devices, in particular to a mechanical sealing ring with a magnetic ring. Background technique [0002] At present, the non-contact mechanical seal is separated by the lubricating film between the two sealing end faces. Generally, the thickness of the lubricating film is on the order of microns. In actual operation, due to various accidental factors, the film-forming state of the lubricating film will be unstable. At this time, there may be rubbing on the sealing end face. Although slight rubbing will not immediately cause seal failure, it will It may also lead to further deterioration of the film-forming state and eventually cause failure. Therefore, for non-contact mechanical seals, avoiding the contact of the sealing end face can improve its service life and reliability. Contents of the invention [0003] In order to overcome the deficiencies in the above-mentioned prior art, the object ...
