1. The air supply system contains moisture. When the temperature is below 0 degrees, the moisture will freeze on the inner wall of the air duct. Similarly, the pipe diameter will be reduced. What is more serious is that sometimes it will even cause individual pipes to freeze completely, hindering work. Therefore, the quality of compressed air is not only determined by its pressure, but also by its humidity.
2. It is not conducive to the compression of the machine, and the compression equipment and pneumatic machinery are subjected to hydraulic shock. If the cooler and the cylinder store a lot of water, it will also cause machine damage accidents;
3. Affect the volumetric efficiency of the gas;
4. The water in the air is very corrosive, which makes the compression equipment and pneumatic machinery easy to rust and shorten the service life;
5. The water in the air narrows the compressed air passage and increases the resistance of air flow;
6. The water in the gas mixes with the lubricating oil during the compression process, which will reduce the lubrication efficiency and increase the wear of the machine parts. In the rubber circulating lubrication packing, it will not only cause poor sealing but also deteriorate the lubricating oil;
7. One cubic meter of wet air (that is, the density of gas molecules) is less than the weight of the same volume of dry air. At the same time, when the compressed air passes through the cooler gas tank and pipeline, most of the water vapor is condensed, so the production capacity calculated by weight will be reduced;
