摘要
螺旋槽密封是一种非接触式且能达到“零泄露”的新型密封 ,近年来在航空航天、石油化工等领域得到了广泛应用。本文采用雷诺方程和差分数值方法对双槽结构型螺旋槽密封的密封性能进行了分析 ,讨论了处于稳定密封状态下密封结构参数和工况参数对螺旋槽端面密封性能的影响程度 ,并将分析结果与实验结果进行了比较。结果说明了密封性能受工况参数和结构参数的影响情况 ,也表明所采用的方法和编制的程序具有较好的应用价值。
As a new noncontacting, non-leaking face seal, t he spiral groove seal has been used widely in the past few years, such as in aer ospace and petrochemical industry. Using the numerical method, we discussed the performances and effective elements in steady seal condition of the double-spir al groove seal. In addition, the result is compared with the available data. The results show that the program written with this numerical method has good appli cation value.
