Standard or custom size Buffer O Ring

 
Product Description

  

Description of Buffer O Ring
Operational performance of Buffer O Ring

1. Minimal leakage: Buffer O Ring requires minimal leakage, has good sealing effect, and with the increased pressure of the hydraulic oil and improve its sealing function automatically, even in poor working environments such as high pressure and high temperature, the leakage of Buffer O Ring also has no obvious increase.

 

2. Good compatibility: Because Buffer O Ring soak for a long time in the hydraulic oil, swelling, dissolved, or embrittlement harden extremely easily, sealing function loss, so the Buffer O Ring of the hydraulic oil has good compatibility.

 

3. Small friction resistance: In order to avoid or reduce hydraulic equipment produce the bad phenomena, such as low pressure crawling for Buffer O Ring has lower static friction resistance and friction resistance, and its friction coefficient should be very stable.

 

4. Long service life: Buffer O Ring should have good flexibility, heat resistance, cold resistance, pressure resistance, wear resistance and certain physical and mechanical strength etc., and long service life.

The structure of Buffer O Ring

    Commonly used sealing pressure type Buffer O Ring mainly ring, circular ring and rectangular sealing ring, etc., they have some advantages such as simple structure, easy manufacturing, low cost, so they are hydraulic transmission system is widely used in the dynamic and static seal the sealing element. They installed in the sealing groove is usually produce 10-25% of the radial compressive deformation, and the sealing surface is relatively high initial contact stress, there is no pressure to prevent leakage of liquid.

 

    Hydraulic cylinder, pressure of liquid extrusion sealing pressure type Buffer O Ring, make further deformation, and on the sealing surface of the larger with the pressure of the liquid pressure, strictly speaking should be pressure. Higher and higher additional contact stress and contact with initial stress together to prevent leakage of liquid pressure. But when work pressure is greater than 10 mpa, in order to avoid quality synthetic rubber sealing part of the compression type Buffer O Ring are in seal gap in cut off in the hydraulic cylinder reciprocating motion caused by leakage, must be in synthetic rubber sealing quality compression type Buffer O Ring of the pressure side each set a synthetic resin retainer, such as nylon retainer, polyformaldehyde collar and filled ptfe ring.

 

    Due to synthetic rubber sealing quality compression type Buffer O Ring has larger compression deformation at work, so the static friction resistance particularly large, usually more than twice the kinetic friction resistance. So much static friction resistance in some low pressure hydraulic transmission system is bound to cause adverse phenomenon such as low pressure and difficult to handle crawling, this is the sealing pressure because of the very small size type Buffer O Ring alone is used as the dynamic seal.

SPGO

        SPGO is usually made from synthetic rubber qualitative protection ring and superposition of filled ptfe qualitative square seals use, it can be divided into the hole and shaft used to use to circle, but its sealing function is the same, in accordance with its own initial deformation on the sealing surface of high contact stress, prevent leakage of pressure of the liquid. Hydraulic cylinder, pressure of liquid by elastic ring in the maximum extrusion rectangular sealing ring, make it close to the sealing surfaces, resulting in increased with the pressure of the liquid pressure of higher and higher additional contact stress, contact stress and the initial together to prevent leakage of liquid pressure.

Stainless steel lip oil seal

 

        Stainless steel lip oil seal is made of stainless steel plate, the shell can be rubber or plastic bags, lip with modified PTFE, wall engraved with the spiral groove, it has wide contact with shaft surface, a thrust inward happens when axis rotation, stop the outflow of fluid and achieve effective seal. Skeleton oil seal seal selection of materials for the filled PTFE modified (main filling ingredients for: glass fiber, carbon fiber, graphite, molybdenum disulfide) greatly improve the wearability of PTFE. Temperature range -70 °C to 250 °C, pressure of 3 mpa, suitable for all kinds of brands, various types of screw, sliding vane compressor is used.

Conventional materials: PTFE+SS
