What is a gas spring?

Gas spring is an industrial accessory that can support, cushion, brake, height adjust and adjust angle. It consists of the following parts: pressure cylinders, piston rods, pistons, seal guide sleeves, packing (inert gas or oil and gas mixture), in-cylinder control elements and out-of-cylinder control elements (referred to as controllable gas springs) and joints. The principle is to fill the sealed pressure cylinder with inert gas or oil and gas mixture, so that the pressure in the chamber is several times or several times higher than the atmospheric pressure, and the pressure difference generated by the cross-sectional area of ​​the piston rod is smaller than the cross-sectional area of ​​the piston. To achieve the movement of the piston rod. Due to fundamental differences in principle, gas springs have significant advantages over ordinary springs: relatively slow speeds, little change in dynamic forces (generally within 1:1.2), and easy control.

The disadvantage is that the relative volume is not small, the coil spring is small, the cost is high, and the life is relatively short. Unlike mechanical springs, gas springs have a nearly linear elastic curve. The standard gas spring has a spring constant X between 1.2 and 1.4. Other parameters can be flexibly defined according to requirements and working conditions.
