The classification and characteristics of the air spring

Source: 互联网    Release time:2014-12-18
A, free type gas spring (Zhi Chenggan) (Lift gas spring) is the most widely used for gas spring. It mainly plays a supporting role, only the shortest, the longest two position, unable to stop in the journey itself. The most widely used in automobile, textile machinery, printing equipment, office equipment, engineering machinery industry. Free type gas spring with its light, stable work, convenient operation, price concessions and so on, until a wide application in automobile, engineering machinery, printing machinery, textile equipment industry. Or alpine environment, acidic or alkaline environment.
Two, lockable gas spring (angle, controllable gas spring) (Lockable gas spring) used in most of the medical equipment on the. The gas spring with the help of some release mechanism can travel anywhere in the stop, and stop after the locking force is large (over 10000N).
Three, damper (Damper) in the automotive and medical equipment are more, its characteristic is the resistance change with the speed of operation. Can obviously connected to the velocities of the bodies play a buffering role. The damper is mainly used for the buffer action, it is the biggest characteristic of air spring force changes with the velocity of movement and change. Spring faster period of resistance function point motion when the boot of the gas spring force is obviously increased, and when the action point move very slowly, almost no resistance. Damper is mainly applied in industry washing machine, refrigerator etc..
Four, pull type gas springs (force gas spring) (Gas traction springs) is a kind of gas spring special: when other gas spring is in a free state in the long position, which is under the external force after the motion position is to the shortest from the long position, and the traction type gas spring of freedom state in the short position by traction from the strengths of the weaknesses to run. Pull type gas springs and a corresponding free type, self-locking type etc..
In addition, from the material on and ordinary steel gas springs and stainless steel gas spring. The maximum amount of ordinary steel gas spring, stainless steel pneumatic spring for environmental requirements more demanding places, for example, food machinery, medical equipment, military industry, high temperature characteristics and application.
To judge the quality of a gas spring
Quality evaluation of the merits of a gas spring is mainly considered from the following aspects: the first is the seal, if the seal is not good will arise in the course of using oil spills, leakage and other phenomena; second is the precision, such as the need for gas spring force error of 500N, some manufacturers produced no more than 2N, some manufacturers of the products the possible and the actual needs of the 500N are far; again is the service life, the service life of its fully retractable count; the last is in the stroke force value change, gas spring under ideal condition should be throughout the stroke force value remains unchanged. But due to the factors of design and machining, which makes the gas spring in the stroke force value inevitably change. But the magnitude of change is an important standard to measure a gas spring quality good ring, change of magnitude smaller, indicating that the gas spring quality better, or worse!
