Compressed air, nitrogen and water could be filled in the airspring. If water is filled inside, the antirust coat should be added to protect the cover.
Two characteristics of the airsprings filled with liquid are as follows:
The operating temperature range of our standard industrial airsprings is: -40℃~+80℃.
Our recommended safety factor between the maximum internal air pressure and the fracture pressure is 2.5. Therefore, for an example, if 0.7 Mpa pressure is needed, the fracture pressure should be 1.75 Mpa or more. The fracture pressure of convolution bellows type airsprings decreases along with an increase in height. Hence, there are two decisive factors: maximum extension height and internal pressure. At this point, for the functional relationship between pressure and height, please refer to Inflation Pressure Chart. Appendix figure 2 (P14) (applicable to single, double and three convolution bellows type airsprings).
