How to choose mechanical seals?

For mechanical seals, we should pay more attention to the working period of  mechanical seals whether it can play a sealing effect. In particular, the quality of the seal ring should be excellent,. Generally speaking, we will choose silicon carbide seal rings , regarding carbide seal ring for the core of the seal. Therefore,  how to choose a wonderful mechanical seals? Factors are as following:
1.According to the speed, use of rotary or static, hydrodynamic or non-contact type
2. According to the temperature, determine the friction and auxiliary sealing material, and the correct choice of lubrication, washing, insulation, cooling and other mechanical seal cycle protection system
 As long as we make sure of these factors, we could choose great mechanical seals in a degree.
