O型密封圈在海水中的使用寿命研究
Predicting the Service Lifetime of O-rings in Sea Water
摘要
Abstract
The nitrile rubber (NBR)seals are widely used in nuclear submarines. Understanding the aging failure process and patterns of the NBR in sea water are great significant to improve the reliability of nuclear submarines. Considering the sea water condition, A heat accelerated aging test program for the NBR with four kinds high temperature was designed, based on the experience of dynamic formula and Arrhenius model. The relationships of the temperature, aging time and compression changes were presented through regression analysis methods. In the end, the lifetime of NBR in the different waters was predicted. The results show that the prediction of service lifetime of NBR is 690 days in 251 which are consistent with the actual results.关键词
