The structure and classification of pan plug sealing ring

Teflon (PTFE) is a sealing material with better chemical resistance and good heat resistance than perfluoroelastomer. It can be used in most chemical fluids, solvents, hydraulic oils and lubricating oils. The compression set) is very small, so it can exert the sealing performance for a long time, and HiPerSeal uses various special springs to overcome the elastic problem of Teflon or other high-performance rubber and plastics, and develops a replacement for the vast majority of applications in static or dynamic (reciprocating or Rotary motion) Seals, the temperature range can be from refrigerant to 300℃, the pressure can be from vacuum to ultra-high pressure 700kg/cm, the moving speed can be as high as 20m/s, and the spring can choose stainless steel, Elgiloy Hastelloy, etc. Therefore, it can be used in various high temperature corrosive fluid occasions.
Pan plug seals can be made according to AS 568A standard O-ring grooves (such as radial shaft seals, piston seals, axial face seals, etc.), and completely replace the general O-ring. Because there is no swelling problem, it can be used for a long time. Maintain good sealing performance. For example, for mechanical shaft seals used in high-temperature corrosive environments in petrochemical processes, the most common cause of leakage is not only the uneven wear of the sliding ring, but also the deterioration and damage of the O-ring. The use of HiPerSeal can completely improve rubber softening, swelling, surface Roughening, wear and other problems, thus greatly improving the service life of the mechanical shaft seal.
In addition to the above-mentioned sealing applications in high temperature and corrosive environments, it has low friction coefficient of sealing lip, stable sealing contact pressure, high pressure resistance, and large radial run-out. And the groove size error, it is very suitable for the seal of the air hydraulic cylinder, replacing the U-shaped or V-shaped tightening to obtain excellent sealing performance and service life.
