Several conditions necessary for mechanical seal selection.
The selection of mechanical seal structure type is an important step in selection. Before selection, the following contents must be investigated:
1) Working parameters: operating pressure p (MPa), operating temperature T ( ℃), working speed v (m/s), seal shaft diameter d (mm).
2) Medium characteristics: concentration, viscosity, corrosiveness, presence of solid particles and fiber impurities, whether it is easy to vaporize or crystallize, etc.
3) Host operating characteristics and environmental conditions ——— continuous or intermittent operation.
4) The host has requirements for the allowable leakage amount, leakage direction (internal or external leakage), lifespan and reliability of the seal.
5) The host has restrictions on the size of the sealing structure.
