本文计算分析了影响径向直线槽液体机械密封性能的因素，着重探讨了结构设计参数对密封的泄漏率、开启力和槽坝交界处液体压力的影响，发现非槽区膜厚和槽深对它们的影响最为显著；还分析了槽深对液体膜刚度的影响，发现刚度随槽深的增加而迅速降低，说明槽较深时，其动压效果已不明显，此时槽主要产生流体静压的作用。
In this paper, the factors that affect the performance of the radial linear groove liquid mechanical seal are analyzed and analyzed. The influence of structural design parameters on the leakage rate, opening force and the liquid pressure at the junction of the groove and dam are discussed emphatically. It is found that the film thickness and groove depth The influence of groove depth on liquid film stiffness is also analyzed. It is found that the stiffness decreases rapidly with the increase of groove depth, indicating that the dynamic pressure effect is not obvious when the groove is deep, The role of pressure.
