Star imported fluorine rubber ring diameter 5.33 in dynamic sealing applications: for sealing reciprocating pistons, piston, piston. For sealing oscillating, rotating or helical motion of shaft or spindle. Star imported fluorine rubber ring diameter 5.33 in static sealing applications: Sealed radial stationary parts, such as sleeves, end caps, pipe. Seal axially stationary parts, such as flanges, covers and so on. Star imported fluorine rubber ring operating parameters: dynamic sealing: reciprocating: ≤5Mpa no stalls circle: ≤30Mpa use stalls circle. Rotational motion: ≤5Mpa use stalls circle. Static seal: ≤5MPa no stalls circle: ≤40Mpa use stalls circle. Working speed: reciprocating: ≤0.5m / s. Rotational motion: ≤2m / s. Depending on the material and temperature range :( media). Usually used: -30 ℃ ~ 110 ℃. Special materials: -30 ℃ ~ 200 ℃. Rotational motion: -30 ℃ ~ 80 ℃. Media: By selecting different properties of the material, which can be sealed to the time all of the liquid, gas and chemicals. Star imported fluorine rubber ring features: star-ring can completely replace the O-rings used non circular cross-section, to avoid rolling back and forth motion. Is the basis of the performance of the O-ring on the same system has been improved and increased the size of its standard AS568 entirely to American Standard O-rings. What is a star-shaped ring? Star-ring is the most commonly used hydraulic cylinder seals, it is a typical lip seal, whether or rod for the piston can get a good sealing effect, U-ring in the case of low pressure, rely on lip seal interference deformation due to the contact area is small, the friction force is relatively low, as the pressure increases, the lip elastic deformation increases, tensile, compressive and bending stress increases, U-ring radial clamping force automatically become larger, the length of the contact with the sealing surface continues to increase until the entire axial length of the U-ring in contact with the sealing surface, thus ensuring a good seal under high pressure. Imported star-ring action principle: the star-ring is a double-acting seal itself resilient sealing capabilities. From the initial pre-installation of compression produces a radial or axial contact stress and pressure overlay system to achieve sealing function. Superimposed sealing force increases as the system pressure increases. Under pressure, shaped ring having the same fluid as a high surface tension. You can even transfer the pressure on each side. Star seal is widely used, but the star-ring imported fluorine rubber is mainly used for dynamic sealing diameter 5.33, but its use is restricted by the pressure and speed.
