| "O" type sealing ring |
GB1235-76 quality standard code |
Most of them are static seal, (a few are
dynamic seal), its working pressure is over 100kg/square
centimeter and has performances such as oil-proof, water-proof,
emulsion-proof, good anti-distortion, high abrasion proof
and tear resistance, it is widely used in coal, mechanism,
electronics, electrical power and so on industry hydraulic
pressure system. |
|
| "Y" type sealing ring |
Chemical Industry Department
HG4-335-66 North-west Rubber Industry Goods Institute
Standard Q/XXY-203-80
|
It can endure long-term 100-400
kg/ square centimeter high pressure, do reciprocal motion,
has good physical mechanical performance, especially high
hardness, high tear resistance, abrasion proof and emulsion-proof,
it is widely use in key parts in hydraulic pressure system. |
|
| "J" type sealing ring |
Q/XXY-203/204-80
HG4-332-66 |
It adapt to expose in air, working environment
with much dust, do reciprocal motion under rigid condition.
It has performances of weather-proof, anti-aging, good
abrasion proof and high tear resistance, small friction
coefficient, and is widely use in mechanized equipment
in coal exploit. |
|
| "G" type drum, type sealing ring |
standard of North-west Institute
Q/XXY-203/204/80 |
It is used in hydraulic pressure urn, acting
as high pressure bi-direction in column piston, its working
pressure can achieve 600Kg/ square centimeter and can
substitute Y type ring. Drum type compound rubber goods
has good pressure resistance, small compression distortion
and good abrasion proof, its working sealing is glue(hardness
is about 70) with good sealing performance and reliability. |

| V¡¢U¡¢C¡¢¡÷¡¢hill type sealing ring |
Chemical Industry Department HG4-335-66
North-west Rubber Industry Goods Institute Standard Q/XXY-204-80 |
In emulsion medium and under the pressure
100-300 Kg/ square centimeter, it does high speed reciprocal
movement 300 times/minute, the journey is 80m/m, most
of them apply textile interlayer, resulting in good abrasion
proof, resistance to the corrosion of viscous emulsion,
excellent physical mechanical performance and reliable
seal, long service life. |
