The leakage rate refers to the total amount of fluid leaked through the main seal and auxiliary seal in unit time; it is an important index for evaluating the sealing performance of the fluid. The lea...

The fluid seals have many different materials and structures, mainly gaskets in flanged connections, which are used in pump and valve compression packing. The first step of selecting the correct seal ...

The service life of the seal means the time from the beginning of the seal to the failure of the seal. It is very difficult to predict the life of a sealing device accurately. The study of the sealing...

The sealing performance and service life of mechanical seal are related to the material of each part, especially the material of the end-face seal (friction pair), auxiliary sealing material and sprin...
