摘　　要：反应釜旋转轴常处于高温高压高速的环境下工作,其轴封较易损坏,需维修更换。传统的整体式机械密封结构更换困难,采用剖分式(对开式)机械密封可以较好地解决这一问题。为了证明剖分式机械密封结构的合理性和可行性,需对其受力和变形进行分析计算。针对剖分式机械密封环的应力和变形计算繁杂的问题,结合实际应用实例,采用了有限元法进行建模加载和分析,求得该密封结构的应力分布和变形量均能满足实际生产要求。The shaft of reactor always working in the high temperature high pressure and high speed environment.The shaft end sealing device of reactors goes wrong mostly frequently.Change the traditional integral mechanical seal out is costly or prohibitive,the split seal stucture can solve this problem perfectly.In order to prove the rationality of split sealing structure and advanced,we need to calcuation it’s stress and strain.Aiming at the shortcoming of tedious modeling and big solution,adopts finite element analysis to modeling,loading and computing,the results confirm the stress and strain of split seal structure are full fill the demands.
