Air Spring has Many Advantages in Industry
Air Spring: Air Bag ; Air Shock ; Air Spring Bags
Because of its own advantages, it is widely used in modern industial machine. Because of its own advantages, it is widely used in modern industrial machinery. Using compressed air as a material is a kind of vibration isolator that uses the stress of compressed air in its internal structure as a ductile restoring force. It is a non-metallic torsion spring with spring action. The bending stiffness changes with the load. Generally, the height, bearing capacity and stiffness coefficient of the torsion spring are selected to make the torsion spring equipment have ideal characteristics; the height pressure regulating valve is selected, and the operating height can be moderately operated according to the use regulations, and the spring load can be maintained under the condition of changing spring load. high.
1. It has the performance of high-frequency shock absorption and noise reduction and sound insulation
The air spring is composed of gas and rubber, and the internal structure friction is small, so it will not affect the ability to prevent high-frequency vibration due to the vibration of the torsion spring itself.
2. With precise height control
Air springs allow precise height control by adjusting internal air pressure.
3. Wide range of sizes
Air springs are available with isolation loads ranging from 0.44 kN to over 577 kN per mounting point.
4. Extend the life of industrial equipment
The air spring can prolong the service life of the equipment through its excellent vibration isolation ability.
