The hydrodynamic pressure effect of mechanical seals:

1) Fluid on the sealing surface (flow groove' shape effect (Figure 2-45)

(1) Macro geometry model [Figure 2-45 (a) ~ (1), (p) and (q)]: Inclined blocks (peripheral steps, circumferential slopes, circumferential slopesSeed flow grooves (circumferential tip, straight chord tip, triangular groove, semicircular groove, rectangular groove, arc groove, blade tip, arc groove, spiral groove, herringbone groove), oval sealing surface, etc.;

(2) Circumferential wave degree model [Figure 2-45(o);

(3) Microscopic surface and roughness model [Figure 2-45(x)].
