2、立的;中间环厚度增大时,最高温度和最大等效应力减小,但最大接触压力和泄漏量增大;密封面宽度增???大时,最高温度、最大等效应力和泄漏量增加,但最大接触压力减小。对密封环结构进行优化,得出最佳的动静环伸??出长度、中间环厚度和密封面宽度,优化后机械密封的最高温度、最大等效应力、最大接触压力下降,对机械密封的???运转更为有利。??关键词:中间旋转环式机械密封;密封性能;静环;动环中图分类号:TH136文献标志码:A文章编号:0254-0150(2016)06-077-05StructuralOptimizationofContactTypeIntermediateRotatingRingMech
