When it comes to gas springs, as many of you probably know, they abound in our daily lives, and although they are not usually available to us as a separate entity, they have an essential role to play in the interior of many devices, machines and so on. Although you may already have a general understanding of gas springs, here, I would also like to introduce you to the specifics of gas springs again, I hope to help people who do not know enough about gas springs to fully understand it.
Gas spring is a kind of industrial accessory that can play the functions of support, buffer, brake, height adjustment and angle adjustment.
Gas spring consists of the following parts: pressure cylinder, piston rod, piston, sealing guide sleeve, filler (inert gas or oil and gas mixture), cylinder control element and cylinder control element (refers to the controllable gas spring) and joints.
Principle is in a closed pressure cylinder filled with inert gas or oil and gas mixture, so that the pressure in the cavity is higher than the atmospheric pressure of a few times or dozens of times, the use of the piston rod cross-sectional area is smaller than the cross-sectional area of the piston and thus the resulting difference in pressure to achieve the movement of the piston rod.
Because of the fundamental difference in principle, gas springs have significant advantages over ordinary springs: relatively slow, dynamic force changes (generally within 1:1.2), easy to control; the disadvantage is that the relative volume is not as small as the coil spring, high cost, relatively short life. Unlike mechanical springs, gas springs have a nearly linear elasticity curve. The elasticity coefficient X of the standard gas spring is between 1.2 and 1.4, and other parameters can be flexibly defined according to the requirements and working conditions.
Based on their characteristics and areas of application, gas springs are also known as support rods, gas supports, adjusters, pneumatic rods, dampers and so on. According to the structure and function of gas spring to classify, gas spring has free-type gas spring, self-locking gas spring, traction gas spring, random stop gas spring, swivel chair gas spring, gas pressure bar, damper and so on several kinds of gas spring. At present, the product has a wide range of applications in automotive, aviation, medical equipment, furniture, machinery manufacturing and other fields.
Gas spring classification:
A free type gas spring (support rod) 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. In the automobile, textile machinery, printing equipment, office equipment, construction machinery and other industries are most widely used. Free type gas spring with its lightweight, smooth work, easy to operate, price concessions, etc., 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 automobile, engineering machinery, printing machinery, textile equipment and other industries.
Two, self-locking gas spring: the most used in medical equipment. 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.
Three, stop at will gas spring is mainly used in the kitchen furniture, medical equipment and other fields.
It is characterized by free type gas spring and self-locking type gas spring between: do not need any external structure and can be stopped at any position in the stroke, but there is 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 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 spring is a special kind of gas spring: other gas springs in the free state are in the longest position, that is, after being subjected to external forces from the longest position to the shortest.
The above is the nature of gas springs, principles and classification of the general information that I have organized for you, I hope that this information can help you fully understand the knowledge of gas springs, but if you are already very understanding of gas springs of this information, I hope that you can help me to verify verify that the information I have provided is not already complete it. Some small things in life, small parts may not seem so eye-catching, but it can really give us great help, therefore, I hope we can have a pair of "equal treatment" eyes.
