活塞环密封件是一种普通的开口环形密封件(split ring seal),它用于内燃机、空气和气体压缩机、以及泵中作往复密封件证明是很好的.在这些用途中,它在平均往复速度达2000呎/分的高速下运行.质量精良的活塞环密封件,通常叫开口环密封件或金属密封环,现在常用在要求密封件的操作温度在橡胶和其他非金属材料密封件工作温度极限以上的场合.特别是由于飞机气体涡轮发动机的迅速发展已表明需要有能在较高环境温度下操作的、作为气动和液压作动筒及 Piston ring seals are common split ring seals that prove to be good for reciprocating seals in internal combustion engines, air and gas compressors, and pumps. In these applications, With an average reciprocating speed of up to 2,000 ft / min High quality piston ring seals, often called split ring seals or metal seal rings, are now commonly used where seals are required to operate at temperatures between rubber and other non-metallic seals Operating temperatures above the limit of the occasion, especially since the rapid development of aircraft gas turbine engines have shown that there is a need to be able to operate at higher ambient temperatures, as pneumatic and hydraulic actuators and
