The basic principle of rolling equipment
The basic principle of rolling seal for selection:
1. according to the pressure of the sealed cavity, the sealing structure is determined by the balance type or the non balanced type, the single end face or the double end face, etc.;
2. according to the working speed, determine the use of rotary or static, hydrodynamic or non-contact type;
3. according to the temperature and fluid properties, to determine the friction pairs and auxiliary seal materials, and the correct choice of lubrication, washing, thermal insulation, cooling and other mechanical seal circulation protection system, etc.;
4. according to the installation and sealing of the effective space, determine the use of multi spring or single spring or spring, the inside or outside.
