The spring energy storage sealing ring is also called pan plug seal or spring actuated polytetrafluoroethylene sealing ring (PTFE is commonly known as "Teflon"), which is a U-shaped Teflon seal with a special spring inside. The fluid pressure of the upper system pushes the sealing lip surface out and gently presses the sealing metal surface to produce a very good sealing effect. Various special springs are used to overcome the elastic problems of Teflon or other high-performance rubber plastics, developed and Replace most of the seals used in static or dynamic, reciprocating or rotating motion, the temperature range can be from cold coal to 300 ℃, the pressure can be from vacuum to super high pressure 1400kg/cm, the moving speed can be up to 20m/s, and the spring can be adjusted according to the application Stainless steel, Elgiloy, Hastelloy, etc. are selected for different use environments. The spring form can also be selected from H spring\V spring\C spring\F spring according to different working conditions. The materials that our company can make include various rubber materials (NBR, FKM, FFKM, SIL, EPDM, HNBR, CI, etc.), various polyurethane materials (oil resistance, hydrolysis resistance, high temperature resistance, food grade, ultra-wear resistance, etc.), various engineering plastics (PTFE, PTFE composite, ultra-high molecular polyethylene, PA, POM, phenolic resin, etc.) and metal materials.

Parameters

The internal open type is suitable for internal positive pressure conditions. The C-ring is a typical self-sealing structure. When the medium pressure enters the C-ring in the working state, the pressure self-tightening effect is generated on the C-ring from the inside to the outside, that is, the greater the system pressure, the better the sealing effect. Due to the principle of opening and self-sealing, it is only necessary to overcome the elasticity of the sealing ring itself during installation, so a very ideal sealing effect can be obtained without using a large pre-tightening force. Our company adopts INCONEL 718 alloy to manufacture.

Teflon (PTFE) is a sealing material with better chemical resistance than fluororubber (FKM) and good heat resistance. It can be used for static, dynamic, reciprocating and rotating motions. It has strong corrosion resistance and good dimensional stability; it can withstand Rapid changes in temperature in the environment; do not pollute food, medicines and pharmaceutical liquids; can be applied to most chemical fluids, solvents, hydraulic oils and lubricating oils, and can exert sealing performance for a long time because of its small swelling

The spring energy storage seal ring can also be made according to the AS568 standard O-ring groove (such as radial seal, piston seal, axial seal), which completely replaces the general O-ring. Excellent sealing performance, such as mechanical shaft seals used in high-temperature and corrosive environments in petroleum and petrochemical industries, the most common cause is not only the uneven wear of the sliding ring, but also the deterioration loss of the O-ring, which can be completely improved by using a spring energy storage sealing ring Rubber softening, swelling, rough surface, abrasion and other problems. Therefore, the service life of the mechanical shaft seal is greatly improved.

Because it is suitable for both dynamic and static conditions, in addition to the above-mentioned sealing applications in high-temperature corrosive environments, because of its low friction coefficient of sealing lip, stable sealing contact pressure, high pressure resistance, large radial deflection and groove size error, it is very It is suitable for the seal of the empty hydraulic cylinder, replacing the U-shaped or V-shaped compression to obtain excellent sealing performance and service life.

Youjia company can quickly customize any specification, any size pan seal and spring energy storage seal ring according to customer requirements.
