Introduction
The coupling rubber seal is a seal used for coupling parts, usually made of rubber material. Their main function is to prevent liquid or gas from leaking from the coupling part, and at the same time, they can absorb vibrations caused by temperature changes, pressure fluctuations, vibrations, and other factors to protect the equipment from damage.
Rubber seals are suitable for various mechanical equipment, such as pumps, fans, compressors, mixers, etc. They provide a reliable sealing guarantee for the normal operation of the equipment and avoid leakage and failure.
Sealing principle
The sealing principle of the coupling rubber seal is to use the elasticity and plasticity of the rubber material to compress it between the two joint surfaces to form a sealed isolation layer to prevent the leakage of liquid, gas, or solid particles.
When the coupling is running, the rubber seal adheres closely to the sealing surface under the action of pressure and its elasticity, forming a seal. At the same time, rubber seals can also absorb vibration and impact, reduce noise and wear during equipment operation, and improve equipment reliability.

Advantages
1. Improve transmission efficiency: Coupling rubber seals can improve transmission efficiency by transmitting load and reducing energy loss.
2. Reduce noise: Rubber seals can effectively reduce resonance and mechanical noise generated during the transmission process, and play a positive role in reducing noise.
3. Reduce vibration: Coupling seals have good shock and vibration absorption capabilities, which can reduce vibration during mechanical operation and improve the operating stability and reliability of the machine.
4. Good elasticity and sealing performance: The rubber seal is made of rubber material and has good elasticity and sealing performance. During the operation of the coupling, the rubber seal can closely fit on the sealing surface to prevent liquid or gas leakage and ensure the normal operation of the equipment.
5. Strong adaptability: Coupling rubber seals are suitable for various couplings and mechanical equipment, and can meet different usage needs. Whether in chemical, petroleum, metallurgy, and other industries or food processing, pharmaceutical, and other industries, rubber seals can play an important role.
