Mechanical seal selection method:
According to different working conditions and medium properties, mechanical seals are resistant to high temperature and low temperature mechanical seals, high pressure and corrosion resistant mechanical seals, mechanical seals resistant to particulate media, and mechanical seals suitable for easily vaporized light hydrocarbon media. The use of mechanical seals of different structural types and materials.
The basic principles of mechanical seal selection are:
1: According to the pressure of the sealed chamber, it is determined that the sealing structure is balanced or unbalanced, single-end or double-end.
2: According to the working speed, determine the use of 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 material, as well as the correct choice of lubrication, washing, insulation, cooling and other mechanical seal protection system.
4: According to the effective space of the installation seal, it is determined to use multi-spring or single spring or wave spring, built-in or exterior type.
