What is the general flow requirement of pneumatic dust butterfly valve for sewage treatment? 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.
Distinguish the Teflon compensator plane from the non-metallic flexible compensator
The axial outward pressure corrugated compensator is usually used when the gas pipeline passes through the structural expansion joint of the roof (or podium roof). The device position shall generally meet the following conditions:
(1) The compensator plane shall be on the same plane as the straight pipe section.
(2) The center of the compensator shall be on the same vertical line with the center line of the expansion joint.
(3) A fixed support shall be set on both sides of the square compensator. The support position and mode shall be selected by the design.
One end of the compensator should be close to the fixed pipe support. If it is too long, the guide frame should be set according to the setting request of the first guide frame. The maximum spacing of other guide frames can be calculated as follows: LGmax - maximum guide spacing (m); E - Elastic modulus of pipeline data (N/cm2); Inertia moment of i-tp pipe section (cm4); KX compensator axial stiffness (N/mm), X0 compensation amount positioning displacement (mm). When the compensator is compressed and deformed, the symbol "+" corresponds to "-" when it is stretched. When the pipe wall thickness of PTFE compensator is designed according to the standard wall thickness, LGmax can be selected according to the relevant specifications.
