Information
According to its characteristics and different application fields, self-locking gas springs are also called support rods, gas brackets, angle adjusters, pneumatic rods, dampers, etc. So what are the structural characteristics of gas springs? Here is some information on how self-locking gas springs work.
Self-locking gas spring is an industrial accessory that can support, buffer, brake, adjust height and angle. It consists of the following parts: pressure cylinder, piston rod, piston, sealing guide bush, packing (inert gas or oil-air mixture), in-cylinder control element and cylinder.
External control components and connectors, etc. The principle is to fill the airtight pressure cylinder with inert gas or oil and gas mixture, so that the pressure in the cavity is several times or dozens of times higher than the atmospheric pressure. The movement of the piston rod is achieved by the pressure difference caused by the cross-sectional area of the piston rod being smaller than that of the piston. Due to the fundamental difference in principle, the self-locking gas spring has obvious advantages over ordinary springs: the speed is relatively slow, the power change is small (generally within 1:1.2), and it is easy to control.
The disadvantage is that the relative volume is not as small as the coil spring, the cost is high, and the service life is relatively short. Unlike mechanical springs, self-locking gas springs have a nearly linear elastic curve. The elastic coefficient x of the standard gas spring is between 1.2 and 1.4, and other parameters can be flexibly defined according to requirements and working conditions.
Its working principle is to fill the closed pressure cylinder with inert gas or oil and gas mixture, so that the pressure in the cavity is several times or dozens of times higher than the atmospheric pressure, and then use the pressure difference between the cross-sectional area of the piston rod and the cross-sectional area of the piston to complete the piston rod. sports.
Due to the fundamental differences in theory, self-locking gas springs have obvious advantages over shallow springs: relatively slow speed, small dynamic changes, and very easy to control; the disadvantage is that the relative volume is not as small as the coil spring, the cost is high, and the service life is relatively short.
The working principle of the self-locking gas spring is that the inert gas is used as the elastic medium, and the elastic element is sealed and lubricated with oil to transmit the pressure, which is referred to as the gas spring. In fact, it is a variant of the sleeve-type air spring, which was developed to further improve the elastic characteristics of the sleeve-type self-locking air spring.
High pressure nitrogen or inert gas and oil form their own circuit inside the cylinder. The damping on the piston makes the rod chamber communicate with the rodless chamber, so that the pressures of the two chambers are equal. The self-locking gas spring has the advantages of light structure, long working stroke, stable movement, and can play the role of damping and buffering; it has a stable and almost constant characteristic line, simple operation, safe and reliable, but high processing cost.
The above is the relevant information on the structural characteristics and working principle of the self-locking gas spring, I hope it can help you.
