*Related Introduction*
The basic principles of mechanical seal selection:
(1) According to the pressure of the sealed cavity, it is determined that the sealing structure adopts balanced or unbalanced, single end face or double end face, etc.
(2) According to the working speed, determine whether to use the rotary or static, fluid dynamic pressure or non-contact type.
(3) According to the temperature and fluid properties, determine the friction pair and auxiliary sealing materials, and correctly select the mechanical seal circulation protection system such as lubrication, flushing, heat preservation, and cooling.
(4) According to the effective space for installing the seal, determine the use of multiple springs, single springs or wave springs, built-in or external.
