摘要：建立了激光加工多孔端面机械密封的计算模型,采用有限差分法求解雷诺方程,获得在不同工况和表面微孔结构参数下密封面的无量纲动压力分布,进而得到了产生最大端面动压力时的优化结构参数,且与试验结果接近。分析结果表明密封面上的微孔可产生明显的动压效应。
A calculation model is developed for mechanical seals with a laser-textured micro-pore face. The dimensionless hydrodynamic pressure distribution on the seal face at various conditions and micro-pore geometry parameters is obtained from a solution of the Reynolds equation by finite difference method. An optimum micro-pore geometry parameter is found and consistent with experimental results. Results of parametric study demonstrate that substantial hydrodynamic effect can be produced on the seal face with micro-pores.
