Gas support is actually a layman's term, we are accustomed to the industry called support rods, gas springs, and gas support just rely on his own function and structure by the other industry people's common name, the use of support rods from the current point of view, is very broad, from the automobile and motorcycle industry, machinery industry, electronics industry to transportation, fitness, sports and medical equipment, ubiquitous, what is the standard of the gas spring?
Introduction to gas springs
Gas springs (gasspring) is a kind of support, buffer, braking, height adjustment and angle adjustment and other functions of the accessories. At present, this product is widely used in medical equipment, automobile, furniture, textile equipment, processing industry and other fields. According to different characteristics and application areas, gas springs are also known as support rods, angle adjusters, gas pressure rods, dampers and so on. The basic principle of gas springs is to press an inert gas and oil, or an oil-gas mixture, into a closed chamber. According to the structure and function of gas springs, gas springs are mainly free-type gas springs, self-locking gas springs, random stop gas springs, traction gas springs, damper several kinds.
Difference between gas springs and general mechanical springs
General mechanical springs,
the spring force with the movement of the spring has a very large change, while the gas spring in the whole movement of the stroke force value remains basically the same. Judge the quality of a gas spring from the following aspects to consider: first of all, its sealing, if the sealing is not good in the use of the process of oil leakage, air leakage and other phenomena; second is the accuracy, such as the need for 500N of gas springs, some manufacturers out of the force produced by the error of no more than 2N, there are manufacturers of gas springs may be more than the actual need for the difference between the 500N; once again is the service life, the service life of gas springs is based on the fact that it is possible to use the gas spring in the form of the spring, the spring force is not more than 2N, and the actual need for 500N. The service life of the gas spring is calculated by the number of times it can be fully retracted; lastly, it is the change of the force value of the gas spring in the stroke, ideally the gas spring should keep the force value constant in the whole stroke.Gas Spring Standards
We all know that the standards for a product are set by the state, and it takes a process for it to take shape and be widely accepted. The implementation of gas spring standards is a boon to many industries. Standards are realized to better serve the industries associated with them. When we understand and know how to use these standards, where gas springs are used, we are able to quickly select the most appropriate product to bring maximum convenience to production and life.
Therefore, when we use gas springs, we must understand the gas spring standards, so as to maximize the use of gas springs. Whether it is the gas spring material standards, filling gas, air pressure standards, and even some of the small springs, the standard of the hook will affect the function we need in the process of use.GB／T 1239.2-1989 Cold wound cylindrical helical compression springs Technical conditions
