Problems solved by technology

Its shortcomings are that the dynamic and static rings are separate parts, and when installed on site, a positioning mechanism needs to be provided on the shaft. The assembly requirements are high, and the assembly process is inconvenient to operate. It is not easy to accurately ensure the installation and coordination requirements of the dynamic and static rings. It is easy to cause accidental damage to the mating surface of the dynamic and static rings. In addition, the friction ring mounted on the end surface of the dynamic ring is press-fitted on the dynamic ring, which is prone to deformation, so the probability of seal leakage is high.

Embodiment Construction

[0009] The present invention consists of a moving ring 1, a static ring 2, and a ring seat 3. An O-shaped sealing ring 12 and a groove 10 are provided on the inner ring surface of the moving ring 1. The static ring 2 is made of graphite material. There is a friction end face 11 integrated with the static ring, which can overcome the deformation and leakage problem caused by the inlaid friction ring. The permanent magnets 23 are distributed on the static ring 2, and there are and O on the outer ring surface of the static ring 2. shaped sealing ring 22 and groove, a convex ring 30 is provided on the side end of the ring seat 3, a stopper 31 is opened on the inner ring surface of the ring seat 3, and a groove 32 and a groove 32 are opened on the stopper 31 The snap ring 33 and the static ring 2 are installed on the spigot platform 31 and are positioned by the snap ring 33. The moving ring 1 is placed between the inner side of the convex ring 30 in the ring seat 3 and the static ri...

Abstract

The integrated magnetic axial sealing device includes one dynamic ring, one static ring, and one ring seat with one raised ring in the side wall. The static ring is fixed inside the ring seat, and the dynamic ring is set inside the ring seat and between the raised ring and the static ring. The integrated magnetic axial sealing device with dynamic ring and static ring integrated inside one identical ring seat has simple mounting and high sealing performance.

Description

technical field [0001] The present invention relates to shaft seals. Background technique [0002] The existing magnetic shaft sealing device is composed of a split moving ring and a static ring. The moving ring is made of copper material, and a friction ring and a magnet are installed on the end face of the moving ring. The O-shaped sealing ring is connected with the shaft, and the O-shaped sealing ring is provided on the outer ring surface of the static ring to cooperate with the end cover. The moving ring and the static ring are fitted and sealed by magnetic attraction. Its shortcomings are that the dynamic and static rings are separate parts, and when installed on site, a positioning mechanism needs to be provided on the shaft. The assembly requirements are high, and the assembly process is inconvenient to operate. It is not easy to accurately ensure the installation and coordination requirements of the dynamic and static rings. It is easy to cause accidental damage to ...
