Products Description

Star seal ring is one of the common seals in hydraulic mechanical equipment, with a typical four-lip sealing structure, so it is also known as X ring (star ring). Dongsheng seals tell you that in the hydraulic piston or hydraulic piston rod seal using star seal ring can get a good sealing effect, under low pressure conditions, need to rely on the lip interference deformation and sealing effect.

Secondly, because the contact surface of the lip surface is too low, the influence of friction is too low; With the increase of pressure, the sealing lip of elastic material deformation, through the tensile, compression, bending and pressure increase, make the rubber sealing ring automatically radial clamping force become larger and increasing the length of the sealing surface contact, until the whole axial length and the rubber sealing ring sealing surface contact, thereby ensuring high pressure condition with good sealing.

1. What are the classification of the application fields of star rubber sealing ring?

This kind of sealing ring is widely used, but generally mainly used in the dynamic seal, such as sealing reciprocating motion of the piston, piston rod, plunger and seal swing, rotation or spiral motion of the shaft or mandshaft.

The static seal is generally used for radial static parts, such as sleeve, end cover, pipe and seal axial static parts, such as flange, cover plate, etc. By choosing materials with different characteristics, it is possible to seal virtually all liquids, gases and chemicals in a timely manner.

Two, what are the characteristics of the design structure of the star seal ring?

X ring can completely replace the use of O ring, because of the circular sealing section, can avoid the rolling phenomenon of hydraulic reciprocating movement in the process, so that the performance of seals and applications improve the sealing effect.

Three. The working principle of star rubber sealing ring?

X - type rubber seal ring is a double - acting seal with its own elastic sealing ability. The precompression during the initial installation creates a radial or axial contact stress that is combined with the system pressure to achieve the sealing function. The superimposed sealing force increases with the increase of system pressure. Under pressure, the star sealing ring acts like a fluid with very high surface tension, which can transmit the pressure evenly to all surfaces.
