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.
Another factor to consider when choosing or designing a gas spring is the operating temperature of the environment, because extreme heat and low temperature affect the operation. The temperature change affects the pressure exerted by the gas spring to produce the output force. At high temperatures, the sealing permeability increases, and the gas molecules can be more easily sealed. Their designs also include cold closure and open closure, thermal and open, self-raising and self-closing Angle, hump, room temperature and damping performance indicators.
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.
