Air Spring Storage and Maintenance

Storage and maintenance of air springs are crucial to their service life and performance. During storage, the air spring should be completely depressurized and stored in a cool, dry, and well-ventilated indoor environment, away from direct sunlight, ozone sources (such as large motors), heat sources, oils, and chemicals. The ideal storage temperature is between 10-25°C. The air spring should also be protected from prolonged exposure to excessive compression, tension, or distortion. Regularly changing its storage position (e.g., every three months) is recommended. During routine maintenance, perform a visual inspection regularly (e.g., weekly or every shift) to check for abnormal bulges, cracks, scratches, and debonding at the metal joints. Before each operation, ensure that the system pressure is stable and use soapy water to test the air line connections and the air spring body for airtightness. Furthermore, the upper and lower contact surfaces must be kept clean to prevent dirt from abrading the air spring skin. Ensure that the air spring can freely extend and retract during lifting and lowering without external interference or friction. Following these systematic storage and maintenance procedures can effectively prevent malfunctions and significantly extend the service life of the air spring.
