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 magnetic mechanical seal ring includes a cylindrical magnetic moving ring 1 and a cylindrical magnetic static ring 2 adapted to it, and the sealing end faces of the magnetic moving ring 1 and the magnetic static ring 2 are The magnetism is the same. The material of the magnetic moving ring 1 and the magnetic static ring 2 is AlNiCo magnetic material.

[0011] The working principle of the present invention is: when installing a non-contact mechanical seal, the sealing end faces of the magnetic moving ring 1 and the magnetic static ring 2 are opposite, that is, the magnetic end faces of the magnetic moving ring 1 and the magnetic static ring 2 are facing each other, when the two sealing end faces When they are about to contact, according to the principle of same-sex repulsion, the repulsive force between the magnetic moving ...

Abstract

The invention relates to a magnetic mechanical seal ring. Since the seal end surfaces of a magnetic moving ring and a magnetic fixed ring have the same magnetism, and the rigidity of mechanical seal is increased by using repellant of the two end surfaces. The magnetic mechanical seal ring overcomes the defect of seal failure caused by the collision and the friction of the seal end surfaces, has a simple structure and is convenient to use.

Description

technical field [0001] The invention relates to a sealing ring, in particular to a magnetic mechanical sealing 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 of the present invention is to provide ...
