摘要
Abstract
Nowadays in the petrochemical refinery, the most high temperature medium pump is metal bellows mechanical seal. For a typical mechanical seal design, the friction heat from the contact surface of rotating ring and stationary seat may cause dry friction or produce larger temperature gradient,this can cause the sealing ring inside has excessive thermal stress, which leads to contact surface wear deformation, even may cause a hot crack and result in serious leakage of the mechanical seal. This kind of problem serious affects the use of mechanical seal and its performance. This paper combining with the examples from daily operation, this paper introduces in detail the structure and function of metal bellows mechanical seal, and do a simulated analysis on the metal bellows mechanical seal face temperature and stress field. Also provide improvement measures. This paper provides theoretical guidance to the design, manufacture and application of mechanical seal and has practical significance.关键词
