现代工业中,导管、仪表和机器等,都应用密封件.密封件是重要的部件,在有些装置中,甚至是决定性的部件.如果密封件失灵,机器有可能失去作用,甚至成为废物.这是有实际例子的,一些宇宙飞船,如Gemini 11,阿波罗(Apollo)8和12,由于推进剂漏泄,在起飞时就失败了.密封件最常用的工业部门是汽车制造工业.例如内燃机活塞上的密封圈,皮碗等.所以越来越重视对密封件的性能的研究和测试.其中对密封件的结构和材料,正在深入探讨,以满足不断提高的对高温和高压条件的要求.
In modern industry, seals are used in conduits, meters, machines, etc. Seals are an important component, and in some devices, even a decisive component. If the seal fails, the machine may lose its function or even become waste. There are practical examples of some spacecraft, such as Gemini 11, Apollo 8 and 12, that failed at take-off due to propellant leaks.The most commonly used industrial sectors for seals are in the automotive manufacturing industry, such as internal combustion engine pistons On the ring, cup, etc. So more and more attention to the performance of the seal research and testing, including the structure of the seal and materials are being explored in depth to meet the increasing requirements of high temperature and high pressure conditions.
