Summary of seal failure reason:

Usually hard ring (static ring) on the surface of overheating will cause severe wear on the seal ring, such as vertical pump without cooling., spring compression under high temperature and high pressure is too large, axial string move will be too big, can cause the transition of sealing surface wear and tear,
There are four kinds of hard in the check ring surface signs should pay attention to:
(1) ceramic ring rupture;(2) cracking;(3) notch;(4) coating fall off.
Ceramic ring assembly tight is the main cause of fracture, improper assembly is also one of the more common reasons.
Due to both linear expansion rate of the coating material and substrate material is different, so the temperature rises, the ring surface cracks appear, too litas alloy is particularly acute.In more advanced coating material, the nickel-based coating is better than cobalt-based tungsten carbide.For the sealing surface for cooling, can effectively prevent the cracking, residues in the seal on the surface of the solid particles often damage the surface, such as grinding wheel on surface of the sand will damage the hard ring, lead to open or between the sealing surface sealing surface to generate crystal, and after regrinding graphite ring, abrasive materials will be embedded in graphite ring surface.
