High-Speed ​​Flow of Gas and Noise The air in nature is composed of many components, of which 78% is nitrogen (N 2), 21% is oxygen and 1% is other gases. In addition, the air often contains a certain amount of water vapor, air containing water vapor is called wet air, air without water vapor is called dry air. The air in the atmosphere is basically wet air. At a certain temperature, the more water vapor, the more humid the air. As the temperature drops, the amount of water vapor in the air decreases. Air as a transmission medium, the degree of dry and wet drive system has a direct impact on the stability and life. Therefore, the various components of the air has a clear water content, often take some measures to filter out the water in the air. Pneumatic transmission equipment work, often high-speed gas flow, such as cylinders, high-speed valve exhaust, the impact of high-speed cylinder nozzle spout, pneumatic sensor jet. Exhaust gas during pneumatic equipment operation, due to the rapid expansion of the gas at the exit, will produce harsh noise. The strength of the noise varies with the amount of exhaust gas, the velocity of the exhaust gas and the shape of the exhaust passage. The greater the velocity and power of the exhaust gas, the greater the noise. In order to reduce the noise, the shape of the exhaust port should be properly designed and the exhaust speed should be reduced.
