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.
