Background Knowledge：

important and difficult points of the theoretical study of split mechanical seal：

The following is meant to do a plain summary of the important and difficult points of the theoretical study of split mechanical seal from two aspects.

1. The unique structure of the split mechanical seal——the existence of the split surface changes the deformation law of the end face after being heated and compressed, and greatly affects the performance of the split mechanical seal.Carrying out split surface effect research and connection tightness analysis of split mechanical seals in pressure and temperature fields, and proposing methods to improve seal working conditions and sealing performance are the most urgent problems mechanical seal technology research workers face.

2. The establishment of a split mechanical seal design method based on zero deformation or positive and negative offsetting deformation of the end faces of rotary face and stationary seat, along with the development of split end face modification technology research, are the theoretical foundations for its widespread application. After solving the problem of connection tightness of the split surface and how the split surface influence end face’s deformation, the distribution law of dynamic pressure of fluid flowing through end surface will be another hot spot in the research of split mechanical seal technology.
