*Related Introduction*
The basic principles of mechanical seal selection:
(1) According to the pressure of the sealed cavity, it is concluded that the sealing structure should be balanced or unbalanced, single end face or double end face, etc.
(2) According to the operating speed, it is determined that the rotary type or the stop type, the fluid dynamic pressure type or the non-touch type should be selected.
(3) According to the temperature and fluid properties, determine the conflict pair and auxiliary sealing data, and accurately select the smooth, scouring, heat preservation, cooling and other mechanical seal cycle maintenance systems.
(4) According to the useful space sealed by the device, it is determined to use multi-spring, single-spring or wave-spring, built-in or external-mounted.
