The humidity of the air is changed with the change of the air state. When the air is compressed, the temperature rises and the relative humidity decreases.As the compressed air expands, its temperature drops, its relative humidity increases, and water is usually released.So, what is the impact of air humidity on air compressor?
1. It is not conducive to the compression of the machine, which makes the compression equipment and pneumatic machinery suffer from hydraulic impact. If the cooler and cylinder store a large amount of water, it will also cause damage to the machine.
2. Affect the volumetric efficiency of gas. As we all know, air can be compressed, but water can not be compressed.
3, the moisture in the air is very corrosive, resulting in compression equipment and pneumatic machinery easy to rust, shorten the service life;
4. The moisture in the air Narrows the compressed air path and increases the resistance of air flow;
5, wet air one cubic meter (that is, the molecular density of gas), is less than the same volume of dry air weight.At the same time, when the compressed air passes through the cooler storage tank and pipeline, most of the water vapor is condensed, so the production capacity of weight calculation will be reduced;
6. The water in the gas is mixed with the lubricating oil in the compression process, which will reduce the lubrication efficiency, increase the abrasion of the machine parts, and not only cause poor sealing but also deteriorate the lubricating oil in the filler of rubber cycle lubrication.
7. The air supply system contains water. When the temperature is lower than 0 degrees, the water will freeze on the inner wall of the air duct.
Therefore, the quality of compressed air is determined not only by its pressure, but also by its humidity.
