How does the gas spring work?

What should be paid attention to when using controllable gas springs? The controllable gas spring is an industrial accessory with the functions of supporting, buffering, braking, adjusting height and angle. Mainly used for cover plate, door and other parts of construction machinery. It is composed of the following parts: pressure cylinder, piston rod, piston, sealing guide sleeve, filler (inert gas or oil gas mixture), in-cylinder control element and out-cylinder control element (refer to controllable gas spring) and connecting piece. The working principle of controllable gas spring is to fill the closed pressure cylinder with inert gas or oil and gas mixture, so that the pressure in the chamber is several times or dozens of times higher than the atmospheric pressure, and realize the movement of the piston rod by using the pressure difference caused by the sectional area of the piston rod being smaller than the sectional area of the piston. What should we pay attention to when using controllable gas springs? 1. Due to the harsh working environment of construction machinery, the sealing requirements of gas spring are high, and dust and other debris should be prevented from entering the gas spring during use. In addition, sharp tools should be prevented from scratching or damaging the surface of the gas spring piston rod, and the piston rod should not be coated with paint and corrosive chemicals.

The lift table gas spring is a component that can support, cushion, brake, adjust height and angle. The gas spring of the lifting table is mainly composed of piston rod, piston, sealing guide sleeve, packing, pressure cylinder and joint. The pressure cylinder is a closed chamber filled with inert gas or oil and gas mixture. The pressure in the chamber is several times or dozens of times of atmospheric pressure. When the air spring acts, the pressure difference on both sides of the piston is used to realize the movement of the piston rod. Gas springs have different structures and types to meet different requirements.

What is the installation method of the gas spring of the lifting table? 1. The position of the piston rod of the compressed lifting table gas spring must be downward during installation, so as to reduce friction and ensure good damping quality and cushioning performance. 2. When installing and compressing the gas spring of the lifting table, the correct method must be used. When closing, the gas spring of the lifting table moves over the center line, or the door will be pushed open frequently. According to its characteristics and different application fields, gas spring is also called support rod, gas support, angle adjuster, pneumatic rod, damper, etc. According to the structure and function of gas spring, lift table gas spring includes free gas spring, self-locking gas spring, traction gas spring, random stop gas spring, swivel chair gas spring, pneumatic rod, damper, etc. What are the categories of gas springs? Lifting table gas spring Free type gas spring is a widely used gas spring. It plays an auxiliary role and cannot stop on its own during the journey. It is widely used in automobile, textile machinery, printing equipment, office equipment, engineering machinery and other industries. Free gas spring is widely used in automobile, engineering machinery, printing machinery, textile equipment and other industries because of its light weight, stable operation, convenient operation and favorable price, or in alpine, acidic or alkaline environments. Self-locking gas spring (angle adjuster, controllable gas spring) is widely used in medical devices. The gas spring can stop at any position in the stroke through some release mechanisms, and has a great locking force (up to 10000 N) after stopping. Random stop gas spring (friction gas spring and balance gas spring) is mainly used in kitchen furniture, medical equipment and other fields. Its characteristics are between free gas spring and self-locking gas spring: it can stop at any position in the stroke without any external structure, but there is no additional locking force. The effect is mainly achieved by the controller (handle or cable). It can also be achieved through the expansion and contraction of the piston rod. The air spring (air bar) of the swivel chair is mainly used for adjusting the position of the swivel chair. It is characterized by strong controllability and large demand.

1. The piston rod of the gas spring of the lifting table must be installed downward and not upside down, which can reduce friction and ensure good shock absorption quality and cushioning performance. 2. The gas spring is a high-pressure product. It is forbidden to analyze, bake or smash it at will. 3. The gas spring shall not be affected by tilt force or lateral force when working, and shall not be used as handrail. 4. Determining the installation position of the fulcrum is the guarantee that the gas spring can work correctly. The gas spring must be installed in the correct way, that is, when it is closed, it should move above the center line of the structure, otherwise the gas spring will often automatically push the door open. 5. In order to ensure the reliability of sealing, the surface of piston rod shall not be damaged, paint and chemicals shall not be applied on the piston rod, and gas spring shall not be installed in the required position before spraying or painting. 6. Working ambient temperature: - 35 ℃ - 70 ℃ (80 ℃ for specific manufacturing). 7. The gas spring piston rod of the lifting table cannot be turned to the left. If it is necessary to adjust the direction of the connector, it can only be turned to the right. 8. The connection point shall be flexibly rotated and cannot be stuck. 9. The size should be reasonable, the strength should be appropriate, and the stroke size of the piston rod should have an allowance of 8mm.
