Gas spring in our daily life everywhere in the application can be casually cited as an example, as if we usually write with the kind of automatic ballpoint pen, we gently press, our quill out of their own, and then we can write, when we don't need it, we press again, our quill will be retracted, and then carefully observed only to find that due to the There is a spring inside playing a role. But today our gas spring is not the kind of ordinary spring we see, but used in our industrial production, power generation and a variety of high-power machinery above a gas spring, then we will explore the gas spring structure in the end what kind.
Gas spring (gas?spring) is a kind of support, cushioning, 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, adjusters, gas pressure rods, dampers, etc...? 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.
Gas struts is actually a layman's term, our industry are accustomed to call the support bar, gas springs, and gas struts just rely on his own function and structure by other industry people's common name, the use of the support bar from the current point of view, a very wide range of applications from the automobile and motorcycle industry, machinery industry, electronics industry to transportation, fitness and sports, medical equipment, ubiquitous, while many manufacturers Staff do not know much about his installation, an advantage of gas springs is simple installation, gas springs generally have connections at both ends, and the specifications of the connectors are many, but all have his characteristics, generally screws, nuts, or directly to the silk teeth, that your equipment to meet his size of the silk holes, and most of all is the gas spring up and down the installation of piston rods must be down, up the cylinder, so that meet the The working principle of the gas spring. Pneumatic damping groove, with which a gradual resistance can be generated, in order to make the hydraulic rod slow expansion and contraction. Do this damping groove need special equipment, generally only professional pneumatic rod factory can process.
Gas spring is a gas and liquid as the working medium of an elastic element, by the pressure pipe, piston, piston rod and a number of couplings, its internal high-pressure nitrogen, due to the piston internal through-hole, the piston at both ends of the gas pressure is equal to the piston cross-section on both sides of the different, one end of the connection with the rod and the other end does not have, under the action of the gas pressure, the pressure to the small side of the cross-section of the pressure, produce to the Under the action of gas pressure, the pressure on the side with the smaller cross-sectional area is generated, i.e. the spring force of the gas spring, the size of which can be set by setting different nitrogen pressures or different diameters of the piston rod. Unlike mechanical springs, gas springs have a nearly linear elasticity curve. The coefficient of elasticity X of standard gas springs is between 1.2 and 1.4, other parameters can be defined flexibly according to the requirements and working conditions.
Classification of gas springs
One, free-type gas springs (support rods) (Lift?gas?springs) is the most widely used gas springs. 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 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 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 be stopped at any position in the stroke, and after stopping there is 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 the controller, the valve will close independently and the piston rod will lock 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.
Through the above we have for the gas spring structure inside the secret of the discussion, we know how our gas spring is to work, we also know the gas spring in our industry as well as the movement of high-powered machinery to play a great role in the above, but also because of the gas spring so magical structure, will create a lot of manpower can not be created, but also to improve the usual our Production efficiency of these issues. The power of the gas spring through the introduction we also have some understanding, so we are more hope that we apply it to our lives in need of places, rather than some of the wayward.
