Abstract
Spiral groove mechanical seal is one of the most favorite method when considering the extreme conditions in terms of the high speed, high temperature and high pressure in the industry. In this paper, the distribution of the temperature field and deformation of the friction pair interface of the spiral groove mechanical seal was studied based on the numerical simulation method. The results showed that the deformation of the sealing ring was relatively large with respect to the film thickness. On the other hand, the maximum deformation of the primary ring and mating ring was less affected by the speed, but the influence of the different pressure was relatively large. Therefore, the pressure of the mechanical seal needed to be controlled in production.
