The invention relates to a high-temperature and wear-resistant bionic sealing ring for rotary sealing. It can be used in static sealing structure and rotating dynamic sealing structure. It has excellent static sealing and dynamic sealing performance, and is resistant to wear and high temperature environment at the same time, which reduces the aging, wear, tearing and other failure phenomena of rubber sealing ring in rotating dynamic sealing. . The technical solution is: the bionic sealing ring has three sealing contact surfaces and a medium action surface, one or more oil grooves are distributed in the middle of the sealing contact surface, the oil grooves are U-shaped or V-shaped structures, and the oil grooves on the three sealing contact surfaces are along The circumferential direction is spirally distributed, and bionic pits are evenly distributed on the surface of the sealing contact surface. The bionic sealing ring can also be applied to harsh working conditions such as high temperature and many impurities.
Description
Technical field [0001] The invention relates to the field of rubber seals, in particular to a high-temperature and wear-resistant bionic sealing ring for rotary dynamic seals. Background technique [0002] Rubber sealing rings are widely used in machinery, instrumentation, petrochemical, transportation, aviation, aerospace, nuclear industry, marine and other fields, and the sealing performance of the sealing ring is directly related to the reliability and safety of the entire system. Generally, seals can be divided into static seals and dynamic seals. Existing rubber seals can achieve good static seals, but they are prone to failure in dynamic seals, especially in rotating and dynamic seals. A large amount of heat generated by the relative motion accelerates the aging of the sealing ring, and impurities entering the sealing surface will aggravate the wear failure of the sealing ring surface. Therefore, it is of great significance to design a high temperature resistant and wear r...
