Gas
Spring:
It consists of the following parts:
pressure cylinder, piston rod, piston, sealing guide sleeve, filler (inert gas
or oil and gas mixture), cylinder and cylinder control element the control
element (of a controllable Gas Spring) and joint. Principle is in the closed
pressure cylinder filled with inert gas or oil and gas mixture, the cavity is
higher than atmospheric pressure several times or dozens of times, the
cross-sectional area of the cross-sectional area of the piston rod is smaller
than the piston to produce pressure difference to achieve the movement of the
piston rod. Due to the different fundamental principle, the gas spring than
ordinary 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 small
volume spiral spring, high cost, relatively short life. Unlike the mechanical
spring, air spring has a nearly linear elastic curve. X between elastic
coefficient of the gas spring 1.2 and standard 1.4, other parameters according
to the requirements and conditions of flexible definition.
Category:
According to the characteristics and applications
of different gas spring, also known as the supporting rod, air support,
recliner, pressure rod, dampers etc. according to the structure and function of
the gas spring to classify gas spring free type gas spring, self-locking gas
spring, pull type gas springs, random stop gas spring, gas swivel chair spring
damper, 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 have
been widely used.
Structure
and Function:
Gas spring is a kind of lifting spring can
be labor-saving, can be divided into self locking gas spring (such as the
bottom of the lifting seat backrest, boss chair, etc.) can not be self locking
gas spring (lifting support such as car trunk, closet doors), the structure of
the gas spring is mainly composed of a sleeve, a piston and a piston. Bar, with
a high pressure air or high pressure nitrogen in the sleeve, due to the
pressure difference between the ends of the piston area ranging, push the
piston and piston rod movement and support people or objects.
How
to Select the Right Gas Spring:
Quality evaluation of a gas spring quality
mainly from the following aspects: first is the seal, if good sealing will
appear in the process of using oil spills, leakage and other phenomena; second
is the precision, such as the need to 500N the gas spring force, some
manufacturers out of the error is not more than 2n, some manufacturers of the
products may and the actual needs of the 500N is quite far; again the use of
life, the life of its fully retractable count; the last is in the process of
the force value change, gas spring under ideal condition should force values
remain constant throughout the trip. But due to the factors of design and
manufacture, the gas during the spring force value inevitably changes. But the
magnitude of change is an important criterion to measure the quality of the gas
spring, the magnitude of change is small, the better the quality of the gas
spring, and vice versa Worse!
