Gas spring is how to work?

 As the piston rod is introduced into the cylinder (compression stroke), the internal pressure increases according to the volume of gas displaced buy the rod.  A gas filled spring consists of a precision rod attached to a piston moving within a sealed cylinder containing nitrogen at high pressure.  Output forces are the result of the differential between the pressure in the cylinder and atmospheric pressure outside the cylinder acting on the cross-section of the rod. This increase in Force or K-Factor is normally between 5% - 50%.  In comparison to mechanical springs, gas springs are almost constant force.Because they operate on simple pressure differentials, gas springs will perform as well in the vacuum of space as they do on land.

Rigid in Tension Lockable Gas Springs

When a locked, rigid in tension springs are subjected to a compression load, only the compressible gas resists the force transmitted from the piston to the floating piston. However, because the oil on the other side of the locked piston cannot expand the movement permitted is significantly less than experienced on a flexible locking gas spring. This gas will consequently compress and permit the rod to move. In addition, because the oil is always held between the piston and nose bearing (containing the main seal), a rigid in tension spring can be used in any orientation.

Several common gas spring

1, the damper
Dampers used from the buffer, its greatest feature is the gas spring force changes as velocity changes. When the gas spring force to guide the role of point faster movement times significantly increased resistance in the spring, and when the role of point movement is slow, the resistance is almost no. Dampers are used in washing machines, refrigerators and other industries.

Gas spring works

Gas and liquid gas spring is a flexible medium for the work element, the pressure tube, piston, piston rod and a number of connected pieces of composition, its internal high pressure nitrogen gas charge, as with through hole inside the piston, the piston ends Qiti pressure equal to, but different cross-sectional area on both sides of the piston, a piston rod and the other end of the termination are not, in the gas under pressure, resulting in small cross-sectional area to the side of the pressure and gas spring stretch, stretch the size of the can set different nitrogen pressure or the set of different diameter rod. The difference is that with mechanical springs, gas springs with near-linear elastic curve. Standard gas springs between the elastic coefficient of X between 1.2 and 1.4, other parameters can be flexible according to the definition of requirements and conditions

Gas Spring features a simple definition and structure

Gas springs can play a supporting, buffer, brake, height adjustment and angle adjustment features such as industrial parts.

Structural features: gas spring by the pressure cylinder, piston rod, piston, seal-oriented sets, fillers (inert gas or gas mixture), the cylinder control devices and control elements outside the cylinder (defined as controllable gas springs) and the joints and other parts.

Gas spring and the difference between ordinary spring

Gas spring is the principle gas pressure in the sealed cylinder filled inert gas or gas mixture, so that the pressure chamber is several times higher than the atmospheric pressure, or a few times, using cross-sectional area smaller than the piston rod cross-sectional area to the pressure difference to achieve the movement of the piston rod.

A simple classification of gas springs

1, free type gas spring (rod) (Lift gas spring) is the most widely used gas springs.

Second, self-locking type gas springs (adjuster, controllable gas spring) (Lockable gas spring) in the application of medical devices on the most.

gas spring

gas spring can play as a support, buffer, brake, height adjustment and angle adjustment features such as industrial parts. It consists of the following components: pressure cylinder, piston rod, piston, seal-oriented sets, fillers (inert gases or gas mixtures), cylinder and cylinder control components outside the control elements (referring to the controllable gas springs), and joints and so on. The principle is the pressure in a confined cylinder charge into the inert gas or gas mixture, so that the pressure of the body cavity is several times higher than the atmospheric pressure, or a few times, using cross-sectional area smaller than the piston rod of the cross-sectional area to generate pressure difference to achieve the piston rod movement. As the principle on the fundamentally different than ordinary spring gas spring has very significant advantages: speed is relatively slow, the dynamic force changing little (generally less than 1:1.2), easy to control; drawback is that there is no spiral spring relative volume is small, the high cost of life is relatively short. The difference is that with the mechanical springs, gas spring with a near-linear elastic curve. Standard gas spring elasticity coefficient between X between 1.2 and 1.4, other parameters can be flexible according to the definition of requirements and working conditions.

The use of gas springs and room for development

  Gas spring and gradually, as a new term appears in the newspapers some network, and its practical range from some of the basic car trunk, hood support the development of the machinery manufacturing industry, spare parts for equipment support, shock absorption devices, toolbox lid support, medical industry, areas such as fitness equipment, with the further recognition of its usefulness, the use of increasingly wide range.
