Air springs are widely used in road, railway vehicles, large and medium-sized paper machinery, paper industry, mining machinery, sewage treatment, medical machinery, environmental protection washing and many other equipment. For example, the air suspension system of the car uses the air spring as the elastic element, and uses the compressibility of the gas to achieve its elastic effect - the air pressure of the compressed gas can be automatically adjusted with the change of load and road conditions, no matter full load or no load, The height of the whole vehicle will not change, which can greatly improve the ride comfort.
