摘要
以可压缩流体Reynolds方程为基础,采用有限元数值计算方法,对一种新型的双列螺旋槽机械密封在3种超低温介质工作状态下,等闭合力条件的密封槽数进行了优化计算,结果表明,不同粘度的介质下,以取得较高液膜轴向刚度为目标进行的槽数优化结果是不同的:介质粘度低,槽数应偏多;介质粘度高,槽数可偏少。这对不同粘度介质下的参数优化具有指导意义。
According to compressible Reynolds equation, the optimization calculation of groove number of a new double spiral groove face seal, which is assumed that the closure force is constant, was done with three different lubrications under ultra-low temperature condition. The results indicate that the variability of film axial-rigidity is different of different viscosity. The less the viscosity is, the more grooves can be selected in order to obtain large film axial-rigidity.
