Detailed Description

Pan plug seal Features: pan plug seal is a special spring U-built high-performance Teflon seals, by the spring force with the appropriate fluid pressure system, the sealing lip (surface) and gently press and hold the top of the sealed metal surface to produce a very good sealing effect. Actuator spring to overcome the effects of the slight eccentricity of the metal with the surface and the seal lip wear, while continuing to maintain the desired sealing performance. Teflon (PTFE) is a perfluorinated chemical resistance than rubber excellent heat resistance, good sealing material that can be applied to the vast majority of chemical fluids, solvents, and hydraulic oil, lubricating oil, the swelling ( compression set) is very small so it can be to play the long-term sealing performance, and HiPerSeal more use of special springs to overcome the high-performance rubber, Teflon or other flexible plastic problems, the vast majority of the development of alternative application of static or dynamic (reciprocating or rotation) of the seal, the use of refrigerant to the temperature range can be 300 ℃, pressure from vacuum to high pressure 700kg/cm ², speed up to 20m / s, while the spring can be used for different environments, made of stainless steel, Elgiloy Hastelloy, etc. , it can be used in a variety of high temperature corrosion fluid situations. Feng Ke Yi Pan Cypriot Standard AS 568A O-ring groove (eg, radial shaft seals, piston seals, axial face seals, etc.) production, completely replace the common O-ring, because there was no swelling of the problems, it can be long-term good sealing performance. For example, the process used in the petrochemical environment of high temperature corrosion of mechanical shaft seal, the most common cause of leakage in addition to the uneven wear of sliding outside the ring, O-ring is also the main cause of deterioration of damage, completely improved after switching to HiPerSeal rubber softening, swelling, surface coarsening, wear and other problems, which significantly enhance the mechanical seal life. Safe movement pan plug seal, in addition to the sealed environment of high temperature corrosion applications, because of its low coefficient of friction lip seal, the seal contact pressure is stable, resistant to high pressure, allowing greater radial runout (radial run-out) and groove size of the error, it is very suitable for air hydraulic cylinder seals, replace the U-shaped or V-shaped packing and get excellent sealing performance and service life. Pan-plug seal features: sealing performance without the impact of lack of lubrication at start, effectively reduce the wear and friction, and spring through different mix of sealing materials, sealing force can be demonstrated to meet the different needs of various applications using special CNC Machining mechanism as no tooling costs - especially for a small variety of seals, chemical corrosion and heat resistance than the commonly used rubber seals and excellent dimensional stability, no swelling or shrinking the size of the sealing performance deterioration derived problem, structure compact, can be installed in a standard O-ring groove, a substantial increase in capacity and service life of seals, seal groove may be filled with any anti-pollution materials (such as silicone) - but not for radiation, as sealing material for the iron F Long, very clean, does not pollute the process, very low coefficient of friction, even in very low-speed applications is also very smooth, there is no "lag-slip effect, starting friction is small, even if down a long time or intermittent operation, able to maintain low dynamic performance from the main application of the Pan-pan plug plug sealing system for sealing high temperature corrosion, lubrication difficulties in the application of low-friction environment for the development of special seals, different Teflon composite materials, advanced engineering plastics in combination with the corrosion of metal spring fully meet the diversity of the increasingly stringent industry requirements. Typical application examples: 1, loading and unloading arm rotary joint seals with axial 2, spray paint or other paint system valve seals 3, 4 vacuum pump seals, drinks, water, beer filling equipment (such as filling valve ) and 5 seals for food industry, automotive, aerospace and industrial seals, such as power steering 6, measuring equipment seals (low friction, long life) 7, and other process equipment or pressure vessel seals
