First, how to choose the right gas spring
(1) Whether the gas spring sealing performance is good or not, if the sealing performance is not good, then there will be problems such as oil leakage or air leakage, which may affect its normal use.
(2) Whether the degree is good or not, mainly refers to the error of the force produced.
(3) Its service life is long, which is generally reflected by the number of full extensions. If the number of expansions is large, the service life is long.
(4) The change in the force value during the stroke should remain unchanged under ideal conditions, but the value will inevitably change due to some objective factors. However, the smaller the change, the better the gas spring quality.
Precautions during installation
1. For the selection of the gas spring, before determining the installation position, first select the model and specifications of the manual.
2. The gas spring should not be subjected to tilting or lateral forces during operation.
3. The piston rod is not painted, and the gas spring is not allowed to be sprayed and painted after being installed in the desired position.
4. The gas spring is a high-pressure product, please do not analyze it at will.
5. The gas spring is strictly prohibited from being fired and bumped.
6. Gas spring piston rod, do not rotate to the left.
Third, the characteristics of gas springs
The gas spring is a telescopic rod with a similar lifting force. It is widely used in automobiles, airplanes, medical equipment, aerospace equipment, textile machinery and other fields. Its internal structure is a piston rod that can move linearly in a closed cylinder. The closed cylinder is filled with a liquid 2-gas two-phase mixture composed of a high-pressure gas and a liquid that can dissolve a part of the high-pressure gas. The force of the gas spring is generated by the high pressure gas pushing the piston rod. The driving force is determined by the pressure of the high pressure gas. The amount of high-pressure gas dissolved in the liquid decreases as the gas is compressed and decreases with the expansion of the gas, so that the density of the high-pressure gas in the closed cylinder is always maintained at an almost constant value, that is, the pressure is approximately constant.
