Although gas springs and hydraulic dampers are produced in a variety of sizes and lengths, a special type of spring is applied by means of compressed gas, but one of the two main factors depending on the desired spring force and effective travel of the spring. Application considerations for gas springs include the selection of cylinders of the appropriate size and the springs of the piston according to the force required for the application. For example, the trunk of a car is supported by two gas springs on both sides of the lid, which produce a force that roughly corresponds to the weight of the cover when compressed. Similarly, for an office chair, the force produced by the gas lift should be slightly higher than the weight of the chair, allowing the user to easily move the chair up and down. In addition, in order to prevent the bending of the gas spring flexion, the resulting force should always be consistent with its centerline, especially for the elongated gas spring device.
Another factor to consider when choosing or designing a gas spring is the ambient operating temperature, since extreme heat and cold temperatures can affect the operation. The change in temperature will affect the pressure that the gas spring can exert, thus affecting the output force. At very high temperatures, the seal permeability increases and the gas molecules can more easily escape from the seal. They are also designed according to performance indicators, including cold closing and opening, heat sealing and opening work, self-elevating and self-closing angle, hump, room temperature and damping.
In the design of the cylinder and piston, should also ensure that resistance to dent, damage and wear. Special functions such as external locking and variable damping should also be considered. Safety is another major factor to consider when producing gas springs. As part of this factor, taking into account the applicability of the spring and the installation position strength. In addition, the auxiliary locking mechanism may be incorporated for safety purposes if necessary.
When installing the gas spring, care should be taken to ensure that the piston rod is mounted upright when the piston rod is directed downward. This is to ensure that the rod seal is always lubricated. If you are installing the spring at an angle, make sure that the level of the lubricant is sufficient to always lubricate the rod seal during operation. See more at http://www.autocontrolcable.com/
