The difference between air spring and ordinary spring
1.Stronger elasticity
Compared with ordinary springs, air springs have stronger elastic force and can meet the use of some large equipment. Although the elasticity of ordinary springs is not weak, it may be difficult if used in some large equipment, and ordinary springs need to take up a lot of space, so they are not used in some high-tech products.
2. With shockproof function
We all know that ordinary springs have no shock-proof function, which is the main reason why ordinary springs are easily damaged. Because it is used in large equipment, the spring has to work many times a day. Without the shockproof function, the spring will be worn out every time it works, so it will be damaged quickly.
3. Work performance will not be degraded due to usage time
After a period of use of ordinary springs, the working performance will gradually decrease, because after many times of work, the elasticity of ordinary springs will become worse and worse due to aging. However, the air spring is different, and the working performance will not be reduced due to the increase in the use time or the number of uses. According to the test data of some professional institutions, this kind of spring will not have any problems after 2 years of use.
