Advantage
1. Precise control precision: the air spring shock absorber provides precise height control by adjusting the internal air pressure. This feature eliminates fatigue and one-time setup problems common in other types of isolators.
2. Prolong the life of equipment: air spring shock absorber because of its special shock absorption principle, reflects a great advantage in the maintenance of equipment, when the traditional steel spring is impacted, will produce the phenomenon of self-vibration, the frequency of self-vibration can be directly transmitted to the equipment, resulting in loosening and damage of equipment. Air spring damping is much better, and it is even possible to achieve complete damping, significantly reducing equipment maintenance costs and extending equipment life
3. Wide range of action: air spring shock absorber vibration isolation load at each installation point from 10KG to more than 10 tons, can meet a variety of different production requirements. (Guomat air spring as an example, there may be differences between brands)
4. Superior shock absorption: Air spring shock absorbers provide superior vibration isolation among all types of vibration absorbers. The natural frequency of the system can be as low as 1 hz. The system's natural frequency can be even lower if an additional air storage chamber is added. In order to achieve the same effect, the static deformation of traditional spiral spring shock absorbers should be at least 230 mm.
5. Small footprint: Air spring shock absorbers can withstand the above loads at mounting heights as low as 50mm for vibration reduction. To achieve the same vibration isolation effect, the helical spring requires a free height of 135 mm to 645 mm. (Take Guomat air spring as an example, each brand may vary)
6. The use effect is stable: the air spring shock absorber is unique in that the natural frequency of the system does not change significantly when the load changes. This characteristic, combined with precise height control, makes it particularly suitable for mounting air spring shock absorbers at various mounting points on equipment with uneven loads.
7. Effective noise reduction: Air spring shock absorbers can effectively reduce the
transmission of noise through the structure. Air spring shock
absorbers themselves also do not produce noise because they do not
have the flutter problems of traditional helical springs.
8. Wide use: air spring shock absorber can not only be used to protect the mechanical structure parts which produce vibration, but also widely used to isolate the vibration transmitted to precision machinery through the structure.
