Air cold press rubber seals
Common places in air cooling presses require the use of rubber seals
- Bellows connection: Bellows are usually connected to other components (such as compressors, coolers, heat exchangers, etc.). These connections require rubber seals (such as O-rings) to ensure tightness.
- Valve and valve seat: Rubber seals are also required between the valve and valve seat in the air cooling compressor to ensure the valve's normal switching and sealing performance.
- Joints and pipe connections: Rubber seals are also required at the joints of pipes, joints, and fittings to prevent gas leakage.
- Pipes and pressure vessels: Rubber seals are often used to connect and seal various components in the pipes and pressure vessels of air cooling compressors to ensure the integrity and safety of the system.
- Cylinder and piston: Rubber seals are also required between the cylinder and piston in the air cooling press to prevent gas leakage and ensure the normal operation of the cylinder.
air cooling press bellows rubber O-ring Description
Material: Rubber O-rings are usually made of rubber or elastic polymer materials. Common rubber materials include nitrile rubber (NBR), fluorine rubber (FKM), ethylene propylene rubber (EPDM), etc. Different materials have different chemical stability, temperature resistance, wear resistance, and chemical resistance, so the selection should be based on specific working conditions and requirements.
Structure: The cross-section shape of the rubber O-ring is circular, hence its name. It is usually round or oval in cross-section and is elastic, capable of returning to its original shape when compressed or stretched.
Function: The main function of rubber O-ring is to provide static or dynamic sealing. In air cooling presses, O-rings are used at the connections of bellows to ensure the airtightness of the connections. It can adapt to different pressure, temperature, and vibration conditions and provide reliable sealing performance.
Advantages: Rubber O-rings have the following advantages:
Good elasticity and resilience, able to adapt to different deformation and pressure conditions.
Good wear resistance and chemical resistance, able to be used for a long time in harsh environments.
Relatively low cost and wide range of applications.
