Why Is the Air Spring Shock Absorption Effect Good?
- Air spring shock absorber is the most efficient shock absorber at present, which is better than spring and rubber. Air spring shock absorber is an elastic element composed of three parts: air chamber, rubber elastic diaphragm and support plate. It is an airtight container with internal air filling, which uses the change of air internal energy to achieve the purpose of shock isolation. Its core structure is air spring, which has reasonable structure, wide bearing capacity range and good air tightness. It is suitable for shock isolation of vibrating equipment such as fan water pump, vacuum pump, air compressor, refrigeration compressor unit, air conditioning unit, general equipment, etc.
- Air spring shock absorber is a special shock absorber. It is different from general spring shock absorber. It is mainly realized by rubber compressed air. Because the core is air spring, this shock absorber has its unique advantage. Shock absorbers used in many mechanical equipment must use it to truly achieve the effect of shock absorption.
- Air springs have a lower natural frequency (2.6~5.3Hz) and a higher damping ratio (0.06~0.08), so they can achieve higher seismic isolation efficiency.
