橡胶密封件在高压气态下的“卸爆”效应

"Explosive Decompression" of Rubber Sealing Parts Under High-Pressure Gas Environments

介绍了国内外对橡胶密封件在高压气态介质中的工作原理和"卸爆"效应的研究情况,指出"卸爆"效应对橡胶密封件造成不可恢复的缺陷,因而橡胶密封件在高压气体的使用环境中应正确设计,并匹配合理的橡胶材料,避免"卸爆"现象的发生,提高其可靠性。

In this paper, the researches on the sealing principle of rubber parts in the media of high-pressure gas and the effect of ＂explosive decompression＂ wre introduced. It indicated that explosive decompression led to the irreversible defects of rubber sealing parts, which is the disadvantage to the whole sealing setups. Therefore, under the high-pressure environment, the rubber sealing parts should be properly designed and suitable rubber should be adapted to avoid the occurrence of ＂explosive decompression＂ and improve the reliability.
