Contact Analysis of Sealing Rings for Welding Bellows Mechanical Seal
In this research, the FEM models of sealing rings for welding bellows mechanical seals were established by applying both isolation and integral contact method, and the displacement and stress of sealing ring’s were calculated. The result shows that a wedge-shaped was appeared on the seal face under the medium pressure and spring force. It can be seen that the integral contact analysis effectively illustrated that the convergence and divergence of the wedge-shaped deformation will be occurred in the contact face. The researching results provide a theoretical basis for the furthermore analysis of the deformation and frictional wear and structure optimization of sealing rings for welding bellows mechanical seal.
