The gas spring is an industrial accessory that can support, buffer, brake, height adjust and angle adjust. The air spring can keep the natural frequency unchanged under any load, can simultaneously withstand radial and axial loads, and can also transmit a certain torque. Different load capacities can be obtained by adjusting the internal pressure.
The use of gas springs makes use of springs made of the compressibility of air in closed containers. According to the structure and function of gas springs, gas springs include free type gas springs, self-locking gas springs, traction gas springs, free air springs, swivel seat gas springs, air pressure sticks, and dampers.
Working principle The inert gas or oil and gas mixture is filled in a closed pressure cylinder, so that the pressure in the cavity is several times or several times higher than the atmospheric pressure, and the pressure difference produced by utilizing 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. It consists of the following components: pressure cylinders, piston rods, pistons, seal guide sleeves, fillers, in-cylinder control elements and external cylinder control elements and joints. Because of fundamental differences in principle, gas springs have significant advantages over common springs: they are relatively slow, dynamic and have little change, and they are easy to control; the disadvantages are that they do not have a small volume of coil springs, which has a high cost and a relatively short life.
