Introduction of Air Shock Absorber
The air shock absorber is characterized by its stable shock absorption effect, as its natural frequency remains relatively unchanged despite load variations, which, combined with precise height control, enhances its shock absorption performance. Furthermore, it features high precision level control, allowing for accurate internal air pressure adjustments via a mechanical level control valve to meet the stringent horizontal precision requirements of workbench equipment. Additionally, the air shock absorber excels in noise reduction, effectively minimizing noise transmitted through the structure without generating sound itself and avoiding the flutter issues associated with traditional coil springs.
Basic Principle
The basic principle of air shock absorbers is to use the compressibility of air. When the device is subjected to an external shock or vibration, the air inside the shock absorber is compressed, thereby absorbing and dissipate the energy of the disturbance. By adjusting the air pressure inside the shock absorber, the intensity and response time of its shock absorption effect can be controlled. In addition, air shock absorbers are usually equipped with damping devices to regulate the gas flow and further optimize the damping performance of vibration.
