Hydrostatic effect of mechanical seal
2017-06-11
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,
