Hydrostatic effect of mechanical seal:

(1) Johncrane 680 mechanical seal oblique plane radial slope effect [Figure 2-48(4)]: The radial slope caused by the force or thermal deformation of the sealing surface or machining produces a static pressure effect. For example, it has convergence. Hydrostatic seal with radial gradient of surface and diffusion surface [Figure 2-48(i), (j), (j) and (k)].

(2) The radial gradient effect of the concave-convex surface includes: groove effect [Figure 2-48(b)], step effect [Figure 2-48(c)], orifice effect [Figure 2-48(d) )], capillary effect [Figure 2-48(e)].

(3) Overbalance effect [Figure 2-48(h)].

(4) Surface tension effect [Figure 2-48(h)].

(5) Vaporization effect [Figure 2-48(g)].

(6) Adsorption effect.　　431.html,
