Horse grass mechanical seal, also known as the end seal, than the packing seal has many advantages, such as saving power, reliable sealing, etc. Therefore, the mechanical seal should be used where possible. However, some mechanical seal life is not long, disassembly than packing much more trouble. In this case, it not only shows no advantages, but has become a disadvantage. Therefore, to extend the service life of mechanical seal is to promote one of the key issues. Affect the mechanical seal life of many factors, one of the important one is the static ring material.
