Gas spring classification:
I. Lift gas spring is the most widely used gas spring. It mainly plays a supporting role, only the shortest, longest two positions, in the stroke can not stop by itself. It is most widely used in the automotive, textile machinery, printing equipment, office equipment, construction machinery and other industries. Free type gas spring with its lightweight, smooth work, easy to operate, price concessions and other characteristics, in the automotive, engineering machinery, printing machinery, textile equipment and other industries such as the wide range of applications. The free-type gas spring is widely used in the automobile, engineering machinery, printing machinery, textile equipment and other industries.
Two, self-locking gas spring (adjuster, controllable gas spring) (Lockable gas spring) in the medical equipment used in the most. This kind of gas spring with the help of some release mechanism can stop at any position in the stroke, and stop after a great locking force (can reach more than 10000N).
Three, stop at will gas spring (friction gas spring, balanced gas spring) is mainly used in kitchen furniture, medical equipment and other fields. Its characteristics between the free type gas spring and self-locking type gas spring: without any external structure and can stop at any position in the stroke, but no additional locking force. The effect is mainly achieved by means of a controller (handle or pull wire). It can also be achieved by telescoping the piston rod. When stopped when adjusted in the desired position with a controller, the valve closes independently and the piston rod locks in the required position . When locking occurs, locking can be realized. However, if the locking force is exceeded, the locking function will no longer be effective.
Four, swivel chair gas spring (gas pressure rod) is mainly used in swivel chairs, play a role in adjusting the position. It is characterized by controllable, the demand is relatively large.
Fifth, traction gas springs (tension gas springs) (Gas traction springs) is a special kind of gas springs: other gas springs in the free state are in the longest position, that is, after being subjected to external forces is the longest position to the shortest position of the movement, and traction gas springs in the shortest position of the free state, when subjected to traction from the shortest to the longest position. The free state of a traction gas spring is in the shortest position and moves from the shortest to the longest position when being pulled. Traction gas spring also has a corresponding free type, self-locking type.
Six, damper (Damper) in the automobile and medical equipment are used more, which is characterized by resistance to change with the speed of operation. Can be obvious to the speed of the connected institutions to play a cushioning effect. Damper is mainly used to act as a cushion, and its most important feature is that the force of the gas spring varies with the speed of movement. When the point of action that directs the force of the gas spring is moving relatively fast the resistance of the spring increases significantly, while when the point of action is moving very slowly the resistance is almost non-existent. Dampers are mainly used in washing machines, refrigerators and other industries.
