摘　　要：以4种不同结构类型的密封环为研究对象,分别对不同工况下4种不同结构的密封环进行泄漏量计算及内部流场分析,得出密封环的泄漏量与压力转速等条件有关,且在相同工况下,圆形蜂窝状密封环的密封性能优于其他3种结构的密封环。Four kinds of seal rings with different structures are researched The leakage calculation and internal flow field analysis of four seal rings with different structures are conducted, which shows that the leakage of seal rings is influenced by the pressure and rotate speed Under the same working condition, seal ring with circular honeycomb shape has better performance than the three other structures.
