摘　　要：介绍了新型复合活塞环的结构和密封机理,提出了一种实验方法并依据此方法成功搭建了试验台架,对新型活塞环和传统活塞环的气密性进行了实验对比。总体来看,随着转速的增加,新型活塞环压缩行程漏气量与传统活塞环相比,平均降低值为8.03×10^(-5) kg/s。This article describes the structure and mechanism of the new composite piston ring seal, it proposes an experimental method and based on the success of this method to build a test bench. The new piston rings and piston rings for conventional air tightness test was carried out. Overall, as the speed increases, the amount of leakage of new piston ring compression stroke, compared with-5conventional piston rings, reduced by an average value of 8.03×10 kg / s.
