PTA pan plug seal high pressure spring energy storage seal
Spring Seal/ spring energized seal/ Variseal is a U-type Teflon built-in special spring high-performance seal with appropriate spring force plus system fluid pressure to eject the sealing lip (face) Gently press the sealed metal surface to create a very good sealing effect. The actuating effect of the spring overcomes the slight eccentricity of the metal mating surface and the wear of the sealing lip while maintaining the desired sealing performance.
Teflon (PTFE) is a sealing material that is superior in chemical resistance to perfluoroelastomers and has good heat resistance. It can be applied to most chemical fluids, solvents, hydraulic fluids and lubricating oils. It can be used for long-term sealing performance, using various special springs to overcome the elasticity problem of Teflon or other high-performance rubber plastics, and developing seals that can be replaced by static or dynamic (reciprocating or rotating motion). The temperature range can be from refrigerant to 300 ° C, pressure from vacuum to ultra-high pressure 700 kg moving speed up to 20m / s, and the spring can be used in different environments, stainless steel, Elgiloy Hastelloy, etc., so it can be applied to a variety of high temperature corrosive fluids occasion.
The universal plug seal can be made according to the AS 568A standard O-ring groove (such as radial shaft seal, piston seal, axial face seal, etc.), completely replacing the general O-ring, because it has no swelling, it can be long-term Maintain good sealing performance. For example, mechanical seals used in high-temperature corrosive environments of petrochemical processes, the most common causes of leakage, in addition to the uneven wear of the slip ring, the deterioration of the O-ring is also the main cause, the use of HiPerSeal can completely improve the rubber softening, swelling, surface Problems such as roughening and wear, thus greatly increasing the service life of the mechanical shaft seal.
It is suitable for sealing and static sealing. In addition to the above-mentioned sealing application in high temperature corrosive environment, it has a low friction coefficient of sealing lip, stable sealing contact pressure, high pressure resistance, and allows for large radial run-out. And the groove size error, it is very suitable for the seal of the empty hydraulic cylinder, replacing the U-shaped or V-shaped pressing to obtain excellent sealing performance and service life.
Characteristics
Sealing performance is not affected by insufficient lubrication at start-up
Effectively reduce wear and frictional resistance
Through the combination of different sealing materials and springs, it can display different sealing forces to meet various application requirements. It is made of special CNC processing machine, no mold cost - especially suitable for a small number of various seals.
Chemical resistance and heat resistance are far superior to the commonly used seal rubber, dimensionally stable, and no deterioration in sealing performance due to volume swelling or shrinkage
problem
Compact structure for mounting in standard O-ring grooves
Greatly improve sealing capacity and service life
The groove of the seal can be filled with any anti-pollution material (such as silicone) - but not for the radiation environment
Because the sealing material is Teflon, it is very clean and will not pollute the process. The friction coefficient is very low, even in very low speed applications, it is very smooth, and there is no "slip effect".
Low starting friction resistance, maintaining low starting performance even with long downtime or intermittent operation
application
The universal plug seal is developed for high temperature corrosion, difficult lubrication, low friction application environment, different Teflon composite materials, advanced
The combination of engineering plastics and corrosion-resistant metal springs can meet the increasingly stringent industrial needs of the industry. Typical applications are as follows:
1. Axial seal for loading and unloading arm rotary joint
2, spray valve parts or other paint system seals
3, vacuum pump seals
4. Beverage, water, beer filling equipment (such as filling valves) and seals for food industry
5, automotive, aerospace industrial seals, such as power steering
6. Sealing device for measuring equipment (low friction, long life)
7. Seals for other process equipment or pressure vessels
Sealing principle
The PTFE leaf spring combination U-ring seal (pan-plug seal) is pressed by the appropriate spring tension plus system fluid pressure to gently press the sealing lip to form a very good sealing effect. Working limit: Pressure: 700kg/cm2 Temperature: -200--300°C Line speed: 20m/s Use medium: oil, water, steam, air, solvent, medicine, food, acid and alkali, chemical solution.
