Sealing surface clearance of mechanical seal:

The end face clearance of a mechanical seal is a very important macroscopic geometric parameter, and its size determines the amount of leakage. The expression of the seal end face gap is

For contact mechanical seals, H8B mechanical seals can be regarded as the gap of the sealing surface. Figure 1-2 shows the geometry of the seal end surface gap and the distribution of hydrostatic pressure; for non-contact hydrodynamic seals, the seal The surface gap is calculated according to formula (1-1).
