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.


How to judge the quality of a gas spring

Judge the quality of pros and cons of a gas spring mainly from the following considerations:

First, is its seal, if the bad seal will appear in the course of oil spills, leakage and other phenomena;
