Why does the gas spring support rod shrink and not return?
Sep 02, 2021
1. The gas spring may be damaged and needs to be replaced in time.
2. The gas spring needs to be pressed down to be retracted, and it must be pressed down forcefully.
3. The pressure from the outside is not enough to push the piston rod to retract.
4. It may be that the elasticity becomes smaller, which is caused by the wear of the seals and chronic air leakage caused by the use of too long time, or it may be caused by the chronic air leakage caused by slight abrasion on the surface of the piston rod under the action of gas pressure. The pressure to the side with the smaller cross-sectional area is generated, that is, the elastic force of the gas spring. The elastic force can be set by setting different nitrogen pressures or piston rods of different diameters.
