Application range of air spring
First, air springs can be used on lifting equipment. Compared with the air cylinder or hydraulic transmission system used in the traditional lifting equipment, after using the air spring as the lifting device, the required installation site is small, no equipment maintenance management is required, the application period is long, and the operation process is convenient and quick to disassemble. It is uneasy to cause leakage.
Secondly, it can be used on suspension machinery. The air spring has the advantages of high frequency shock absorption, sound insulation and low natural vibration frequency, which can very well protect against vibration and ensure the reliability and stability of the base of the vibration equipment and the automatic control system. Therefore, it is widely used in equipment such as shock absorption of vibrating screens and shock absorption of seats.
