The Air Spring Can Be Used In Coal Mining Equipment

Air spring is a commonly used elastic element, which is widely used in various vibration equipment. It has the advantages of good stability, low noise, good vibration isolation effect and long service life.

Because of its special shock absorption principle, the air spring shock absorber has great advantages in the maintenance of equipment. When the traditional steel spring is impacted, it will produce a self-vibration phenomenon, and the frequency of the self-vibration can be directly transmitted to the equipment, resulting in loosening and damage to the equipment. The shock absorption effect of the air spring is much better, and it is even possible to achieve complete shock absorption, which significantly reduces the maintenance cost of the equipment and prolongs the service life of the equipment.
