Slip ring sealing apparatus with seal element

Abstract

The present invention relates to a slip ring sealing apparatus, comprising a housing (1), a slip ring (2) and a corresponding ring (3), wherein the slip ring (2) and the corresponding ring (3) are respectively provided sealing surfaces (2a, 3a) attached to each other, the sealing surface of the slip ring (2) is correspondingly arranged on the sealing surface (3a) of the corresponding ring (3), and the slip ring is pressed on the corresponding ring (3) through a spring member (4) supported on the housing (1). According to the technical scheme, the slip ring sealing apparatus employs as simple components with a geometric structure as possible, the slip ring sealing apparatus can present a long-term high sealing performance and a long service life after being smoothly mounted even if under a machinery load, and is characterized in that the slip ring (2) is connected with an elastic sealing element (5), and the sealing element is positioned between the housing (1) and the slip ring (2).

Description

technical field [0001] The invention relates to a slip ring seal according to the preamble of claim 1 . Background technique [0002] Slip ring seals of the type mentioned at the outset are known in the prior art. In this case, a first sealing surface can have graphite-filled silicon carbide as the sliding material; a second sealing surface can have porous silicon carbide as the sliding material. [0003] The slip ring seals described according to the prior art have the disadvantage that the sealing surfaces are often made of brittle, rather hard materials. Such sealing surfaces are damaged by mechanical loads and thus crack. Once a sealing surface is cracked, a reliable seal can no longer be achieved. [0004] Another disadvantage is that the relatively hard and brittle sealing surfaces must be precisely matched to each other in terms of their geometric structure and bonding pressure, so as to obtain reliable sealing. Thus, it is very troublesome to install. [0005] F...

AI Technical Summary

Problems solved by technology

[0003] According to the slip ring sealing device described in the prior art, its disadvantage is that the sealing surface is often made of brittle, relatively hard material

[0004] Another disadvantage is that the relatively hard and brittle sealing surfaces must be precisely and accurately matched to each other in terms of their geometric structure and bonding pressure in order to obtain reliable sealing

In this way, it is very troublesome to install

[0005] In addition, complex geometries can only be produced with difficulty when using hard materials

thereby increasing manufacturing costs
