Analysis of the Hydrodynamic Effect in Laser-Textured Mechanical Seal Faces
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 operating conditions and micro-pore geometry parameters is obtained from a solution of the Reynolds equation by the finite difference method. An optimum micro-pore geometry parameter is found and consistent with experimental results. Results of parametric study demonstrate that the substantial hydrodynamic effect can be produced on the seal face with micro-pores.
