How Do Gas Springs Work？

Gas springs are widely used and can support, buffer, brake, and height-adjust industrial accessories. A gas spring is the same as a mechanical coil spring. They are devices that store energy. The gas spring mainly relies on the use of inert gas to work. When the gas enters the equipment, it will form a closed system.

It consists of a pressure cylinder, piston rod, piston, guide sleeve, etc. This article briefly introduces the working principle and types of gas springs, so that you can better find the right product in the gas spring shop.

What is a gas spring?

The working principle of the gas spring is to fill the closed pressure cylinder with an inert gas or an oil-gas mixture so that the pressure in the cavity is several times or dozens of times higher than the atmospheric pressure. Since the cross-sectional area of the diesel piston rod is smaller than that of the piston, the pressure difference generated by it is used to realize the movement of the piston rod. Compared with ordinary springs, gas springs have advantages including relatively slow speed, little change in dynamic force, and easy control. The disadvantage is that the volume is relatively large, the cost is high, and the life is short. Gas springs have a nearly linear elastic curve compared to mechanical springs. At present, this product is widely used in the fields of automobile, aviation, medical equipment, furniture, machinery manufacturing, and so on.

How to install gas springs?

When installing, the position of the compression gas spring piston rod must be downward, so as to reduce friction and ensure the best damping quality and cushioning performance.

When installing the compressed gas spring, you must use the correct method. Make sure it moves past the center line when closing, otherwise it will often push the door open.

Gas spring types

According to their characteristics and different application fields, gas springs are also called support rods, gas supports, recliners, air pressure rods, dampers, etc. According to the structure and function of the gas spring, there are several types of gas springs, such as lift gas springs, Lockable gas springs, traction gas springs, random stop gas springs, swivel chair gas springs, gas rods, engine damper, etc.

1. A lift gas spring is a widely used gas spring. It mainly plays a supporting role. It cannot be stopped during the operation of the equipment.

2. Lockable gas spring is widely used in medical equipment. It can be stopped during using and has a great locking force.

3. Random gas stop springs are mainly used in kitchen furniture, medical equipment, and other fields. It can be stopped during us But there is no locking force.

4. Air pressure rods are mainly used on swivel chairs to adjust their position.

5. The damper is widely used in automobiles and medical equipment. Its characteristic is that the resistance changes with the speed of operation, and it can buffer the speed of the connected accessories. Its resistance changes according to the speed at which the equipment is operating.
