What are the introductions of the combined V-shaped sealing ring in the hydraulic cylinder?

Forming a V-shaped sealing ring is a common sealing method for hydraulic cylinders. Generally, it is produced by nitrile rubber (NBR) / flax fiber polymer materials. Because NBR has limited temperature resistance, it can only be used in natural environments below 100°C. The temperature of the hydraulic transmission system in the industry is usually high, which limits the use of NBR materials to form the V-shaped sealing ring.

The chemical cross-linking of chloroprene vulcanized fluororubber is based on the principle of oxygen free radicals. After chloroprene is converted into free radicals, it will cause chemical cross-linking reaction. Generally, bis 2,5 dimethyl-2,5-bis (Tert-butyl peroxide) hexane], the 1min drug has a half-life of more than 170C, and does not dissolve at all at room temperature, so there will be no doubt about the problem of glue, and the stable service life of the glue will reach more than several months. Compared with the general binary bisphenol vulcanized fluororubber, the wear resistance of this type of fluororubber has been significantly improved. In order to better achieve heat resistance, glass fiber yarn is selected as the frame material.

The preparation of the V-shaped sealing ring composed of fluororubber cloth cloth takes the fluoroelastomer cloth cloth with the specification model of 130 x 160 x 28 as an example. The fluororubber fiberglass cloth cloth is pre-formed and then installed into the shape press. Ring, V-shaped support point ring and V-shaped seal ring are vulcanized in a tablet computer vulcanizer at 165°C for 30 minutes and then heated at 200°C for 4 hours to obtain fluororubber. V-shaped pressure ring, fluorine rubber cloth V-shaped support point ring and fluorine rubber cloth V-shaped sealing ring. A V-shaped pressure ring with a fluorine rubber cloth, a V-shaped support point ring with a fluorine rubber cloth, and a V-shaped sealing ring with a cloth cloth are composed of a fluorine rubber cloth to form a V-shaped sealing ring.
