Star rubber sealsStar rubber seals and working environment parameters

 

Shenzhen Xu Xinhua Rubber Products Co., Ltd. has strong technical strength and research capabilities to eleven years of unique experience to specific manufacturing rubber products and consistent quality and reliable known to the world, in the market has won wide good credibility.

 

Star shaped rubber sealing ring cylinder is the most commonly used sealing member, which is typically a lip seal, or whether the piston rod can be used to obtain a good seal, U-shaped rubber seal in the case of low pressure next, rely on lip seal interference deformation, due to the small contact area, friction is relatively low, as the pressure increases, the elastic deformation of the lip increases the tensile, compressive and bending stress increases, U-shaped rubber seal ring radial clamping force automatically increases the length of contact with the sealing surface increased until the entire axial length of the U-ring seal in contact with the surface, so as to ensure a good seal under high pressure.

 

Star shaped rubber sealing ring is double-acting seal itself has elastic sealing capability. The initial installation of the pre-compression produces radial or axial contact stress superimposed system pressure to achieve sealing function. The superimposed sealing force increases the system pressure increases. Under pressure, with a star-shaped rubber seals as high as the surface tension of the fluid. It can be transmitted to a uniform pressure on each side.

 

Star wide rubber seals applications, but mainly for dynamic sealing, but the use of pressure and speed restrictions by.

 

Dynamic sealing applications star rubber seals:

 

For sealing the reciprocating motion of the piston, the piston rod of the plunger.

 

For sealing oscillating, rotating or spiral motion of the shaft or spindle.

 

Star-shaped rubber seal static sealing applications:

 

Radial seal stationary parts, such as sleeves, end caps, pipe.

 

Seal axially stationary parts, such as flanges, covers and the like.

 

Operating parameters:

 

Star-shaped rubber seal dynamic sealing:

 

Reciprocation: ≤5Mpa no stalls circle: ≤30Mpa use stalls circle.

 

Rotary motion: ≤5Mpa use stalls circle.

 

Static sealing: ≤5MPa no stalls circle: ≤40Mpa use stalls circle.

 

Working speed:

 

Reciprocation: ≤0.5m / s.

 

Rotational motion: ≤2m / s.

 

:( Temperature range depending on material and medium).

 

Typically application: -30 ? ~ 110 ?.

 

Special materials: -30 ? ~ 200 ?.

 

Rotational movement: -30 ? ~ 80 ?.

 

Media: By selecting different material properties, which can be time to seal all liquids, gases and chemicals.

 

EPDM EPDM rubber ring: with good weather resistance, ozone resistance, water resistance and chemical resistance. Alcohols and ketones can be used to seal the high temperature steam environment may also be used. Suitable for sanitary equipment, automotive radiator and automotive brake systems. Not recommended for food use or being exposed to mineral oil. General temperature range of -55 ~ 150 ?. and working environment parameters
