The gas spring and hydraulic damper is the use of compressed gas to special type spring pressure, produced in the different sizes and length, choose a depends on two major factors, namely the spring force and the effective stroke of spring. The application design of the gas spring requires the selection of suitable springs and pistons according to the force required by the application. For example, the car's box cover is supported by two gas springs on both sides of the lid, when the force produced is roughly equal to the weight of the lid.
Similarly, in the office chair, the force generated by the gas lift should be slightly higher than the weight of the chair, so that the user can easily move the chair up and down. In addition, in order to prevent the buckling deformation of the gas spring, the force produced should always be consistent with the center line, especially for a thin gas spring device.
When designing cylinder block and piston, the resistance to sag, damage and wear should be ensured. Special features should also be considered, such as external locking and variable damping. Safety is another major factor that should be considered when producing natural gas springs. As part of this factor, the suitability of spring and the strength of installation position are considered. In addition, the secondary locking mechanism can be used for security purposes if needed.
When installing a gas spring, make sure that it is installed in the vertical direction and the piston rod is down. This is to ensure that the rod seal is lubricated at all times. If the spring is to be installed in an Angle, be careful to ensure that the oil level is sufficient for the oil rod seal to be lubricated throughout the operation.
