Gas Spring,Stretching Gas Spring,Office Furniture Gas Spring,Lockable Gas Spring
It consists of the following parts:pressure cylinder, piston rod, piston, sealing guide sleeve, filler (inert gasor oil and gas mixture), cylinder and cylinder control element the controlelement (of a controllable Gas Spring) and joint. Principle is in the closedpressure cylinder filled with inert gas or oil and gas mixture, the cavity ishigher than atmospheric pressure several times or dozens of times, thecross-sectional area of the cross-sectional area of the piston rod is smallerthan the piston to produce pressure difference to achieve the movement of thepiston rod. Due to the different fundamental principle, the gas spring thanordinary spring has the advantages of obvious: speed is relatively slow,dynamic force changes little (within 1:1.2), easy to control.
The relative disadvantage is no smallvolume spiral spring, high cost, relatively short life. Unlike the mechanicalspring, air spring has a nearly linear elastic curve. X between elasticcoefficient of the gas spring 1.2 and standard 1.4, other parameters accordingto the requirements and conditions of flexible definition.
According to the characteristics and applicationsof different gas spring, also known as the supporting rod, air support,recliner, pressure rod, dampers etc. according to the structure and function ofthe gas spring to classify gas spring free type gas spring, self-locking gasspring, pull type gas springs, random stop gas spring, gas swivel chair springdamper, pressure rod,Self Locking Gas Spring,Auto Gas Spring,Industrial Gas Spring, Groove Gas Spring,Stretching Gas Spring,Office Furniture Gas Spring, etc.. Several products in the automotive, aerospace,medical equipment, furniture, machinery manufacturing and other fields havebeen widely used.
Gas spring is a kind of lifting spring canbe labor-saving, can be divided into self locking gas spring (such as thebottom of the lifting seat backrest, boss chair, etc.) can not be self lockinggas spring (lifting support such as car trunk, closet doors), the structure ofthe gas spring is mainly composed of a sleeve, a piston and a piston. Bar, witha high pressure air or high pressure nitrogen in the sleeve, due to thepressure difference between the ends of the piston area ranging, push thepiston and piston rod movement and support people or objects.
Howto Select the Right Gas Spring:
Quality evaluation of a gas spring qualitymainly from the following aspects: first is the seal, if good sealing willappear in the process of using oil spills, leakage and other phenomena; secondis the precision, such as the need to 500N the gas spring force, somemanufacturers out of the error is not more than 2n, some manufacturers of theproducts may and the actual needs of the 500N is quite far; again the use oflife, the life of its fully retractable count; the last is in the process ofthe force value change, gas spring under ideal condition should force valuesremain constant throughout the trip. But due to the factors of design andmanufacture, the gas during the spring force value inevitably changes. But themagnitude of change is an important criterion to measure the quality of the gasspring, the magnitude of change is small, the better the quality of the gasspring, and vice versa Worse!
