food pump Mechanical seals

food pump Mechanical seals

Combination of materials
Seal face: Graphite, Silicon carbide, Tungsten carbide, Aluminum oxide
Secondary sealing: Acrylonitrile rubber, Fluorine rubber, Ethylene propylene rubber. Silicon rubber, PTFE
Metal component: Stainless steel

It has a wide application scope and high interchangeabliblity. It is compact in structure. The drive collar is clamped by the drive lug to prevent the spring from dropping. It is reliable in performance and widely used in petrochemical pumps.

APPLICATION

Mmechanical seals are used in pumps, blowers, agitators, compressors, and other rotary shaft equipment.

Seal failure reason analysis

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.
