Gas spring are widely used in daily life. The utility model has good quality, convenient and intuitive operation. It can play a better role and improve the utilization efficiency of equipment. What is the relationship between the quality of the support rod and? Let's look at the answers of professional manufacturers.
When selecting the gas spring, first consider the sealing performance of the support rod. If the sealing performance of the support rod is not good, oil leakage, air leakage and other problems will occur during the use process. The accuracy of the gas spring is also crucial. The accuracy error should not be too large. The error value formed by different manufacturers is different, as long as it is within the normal value scale.
The service life of the support rod is related to the times of complete contraction of the support rod. In the process of application, the stress value of the support rod shall remain unchanged, but if there is any change, it can be ignored as long as the change scale is not too large.
The support rod is an elastic element with gas and liquid as working medium, which is composed of pressure pipe, piston, piston rod and several connecting pieces. The support rod is filled with high-pressure nitrogen. Because the piston has a through hole, the gas pressure at both ends of the piston is equal, but the sectional area at both sides of the piston is different. Under the action of gas pressure, one end is connected with the piston rod and the other end is not connected. Under the action of gas pressure, pressure is generated to the side with small cross-sectional area, that is, the elasticity of the support rod. The elastic force can be determined by setting different nitrogen pressure or piston rod different from mechanical spring, and the support rod has an approximate linear elastic curve. The elastic coefficient x of standard support rod is between 1.2-1.4, and other parameters can be flexibly defined according to requirements and working conditions.
Functional production of gas spring
1. The piston rod of the gas spring must be installed in the downward position, and it is not allowed to be inverted, so as to reduce friction and ensure better damping quality and cushioning effect.
2. It is a high-voltage product. It is strictly forbidden to analyze, bake, bump or use it as a handrail.
3. Working environment temperature: - 35 ℃ -+70 ℃. (80 ℃ for specific manufacturing)
4. Do not be affected by tilting force or lateral force during operation.
5. Determine the installation position of the fulcrum. In order to ensure the working accuracy, the piston rod of the pneumatic rod (gas spring) must be installed downward and not inverted, which can reduce friction and ensure better shock absorption quality and cushioning effect. It must be installed in an accurate way, that is, when it is closed, let it move over the centerline of the structure, otherwise, the door will automatically open. Install in the required position before painting and painting.
