Basis Information of Air Shock Absorber
-
The shock absorption effect is stable: the unique feature of the air shock absorber is that the natural frequency of the system does not change significantly when the load changes. This characteristic, combined with precise height control, results in better shock absorption.
-
High precision level control: The air shock absorber can adjust the internal air pressure through the mechanical level control valve for accurate height control. This feature meets the high requirements forthe horizontal precision of the workbench equipment.
-
Good noise reduction effect: the air shock absorber can effectively reduce the noise transmitted through the structure. The air shock absorber itself does not produce noise and does not have the flutter problem of 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.
