Basic information of air spring damper
The attention of air spring shock absorbers to shock absorbers is constantly increasing. Its shock absorption effect is difficult for many shock absorbers to achieve. Like automobile tires, it uses the compression of gas to achieve the effect of shock absorption, so as to understand the basic information of spring shock absorption.
Structure and working principle of air spring damper:
It is to inject compressed air into a sealed container and use the compressibility of the gas to show the spring effect. Commonly used air spring installation consists of three parts: spring body, additional air chamber and height controller.
Application classification of air spring damper:
1. Vibration isolation installation with air chamber;
2. Vibration isolation installation with additional air chamber.
Use of air spring shock absorber and how to complete the effect:
It is widely used in aerospace and industrial machinery sectors.
1. When conducting air vibration experiments on missiles and aircraft, use air springs to support, reduce the impact of support system vibration, and reach the request of simulating air suspension state;
2. It is used to support automobiles and locomotives and improve the running quality of vehicles;
3. Good effect can be obtained when it is used for fine instrument vibration reduction;
4. Used in industrial machinery, it has more advantages in vibration isolation of low bundle gravity equipment and shock isolation of shock equipment. In the past, the strong appearance of air spring shock absorber has brought great benefits to many industries such as transportation vehicles and industrial machinery, and its tire type damping effect also fits the contemporary social market.
What are the advantages of air spring shock absorber
The air spring shock absorber is a special shock absorber. It is different from the ordinary spring shock absorber. It is mainly made of rubber compressed air. This kind of shock absorber has a common advantage. The shock absorber used in many mechanical equipment must use it to really reduce the vibration.
Advantages of air spring damper:
1. Through the height control valve, the working height of the air spring can be kept constant under any load, and the spring can also have different heights under the same load. Therefore, it is conducive to meeting the requirements of multiple structures.
2. The air spring has nonlinear characteristics, and its characteristic line can be designed into an ideal curve according to the demand.
3. The stiffness of the air spring changes with the load, so the natural frequency remains unchanged under any load, which makes the spring installation have virtually unchanged performance.
4. The stiffness of the air spring can be selected according to the demand by changing the volume of the additional air chamber, and can be selected very low
5. The same air spring can accept axial and radial loads at the same time, and can also transmit torque. Through the adjustment of internal pressure, it can also obtain different carrying capacity, so it can meet the needs of multiple loads.
6. High frequency vibration absorption and sound insulation are good,
7. An orifice is set between the air spring body and the additional air chamber, which can play a damping role. If the aperture is properly selected, the pneumatic butterfly valve may not be set.

3. Protective facilities of pressure reducing valve:
There are generally three types of relief valve installation facilities. Pressure gauges are installed in front of and behind the pressure reducing valve to facilitate the observation of the pressure in front of and behind the valve. There is also a fully closed safety valve behind the valve to prevent the pressure relief valve from jumping when the pressure behind the valve exceeds the normal pressure after failure, including the system behind the valve. The drain pipe is installed in front of the cut-off valve in front of the valve, mainly for the purpose of drainage river flushing, and some drain valves are used. The main function of the bypass pipe is to close the shut-off valves in front of and behind the pressure reducing valve, open the bypass valve, and adjust the flow manually to play a temporary circulation role in order to repair or replace the pressure reducing valve when the pressure reducing valve fails.
