Water content of air from air compressor

The water content of the air from the air compressor is an important indicator, which is affected by many factors, including the working environment, the design of the air compressor equipment and the maintenance status. Generally speaking, the water content of air compressor is usually between 20% and 40%, but the specific value will fluctuate according to the actual situation.

The main reasons for the high water content of the air from the air compressor are as follows:

1. air humidity: The air itself contains a certain amount of water vapor, especially in a high temperature and high humidity environment, the moisture content in the air will be higher. When the humid air is compressed by the air compressor, the moisture in it will also be compressed in, resulting in an increase in the moisture content of the pressure air.
2. Automatic drainer clogged when the automatic drainer of the air compressor itself or the automatic drainer of the air storage tank is blocked, the water that should have been discharged will accumulate in the air compressor, making the air discharged from the air compressor contain water.
3. Drying equipment failure the corresponding dryer is not installed or does not work normally after installation (such as the drying equipment fails and is not found and processed in time), and the compressed gas of the air compressor is not processed in time, resulting in still containing a large amount of water after removal, which cannot meet the normal use requirements.
4. Condensate formation when the air compressor is working, the internal temperature of the head is very high, and the water in the natural air inhaled will form water vapor during the operation of the air compressor, which will be discharged with the compressed air. The air storage tank can not only provide a buffer and storage space for compressed air, but also play a role in cooling the compressed air. When compressed air passes through the air storage tank, the high-speed air flow hits the wall of the air storage tank to generate confluence, which makes the temperature drop rapidly in the air storage tank, liquefying a large amount of water vapor and forming condensed water. If you catch up with wet weather or winter, more condensation will form.

The high water content of the air coming out of the air compressor may bring a series of problems, such as affecting the volumetric efficiency of the air, increasing the resistance of the air flow process, reducing the production capacity, corroding the spare parts of the equipment, reducing the lubrication efficiency, and increasing the wear of the parts. Therefore, it is necessary to take corresponding measures to reduce the air moisture content of the air compressor. These measures include the use of cold and heat exchange technology to pre-cool the hot compressed air, the installation of a drain valve at the bottom of the air storage tank to regularly discharge the accumulated moisture, the use of filtration methods to further process the moisture in the compressed air, to ensure the correct installation of the filter element and to avoid its Displacement or damage, etc.

In addition, in order to more accurately monitor and control the water content of the air from the air compressor, a special water content detection instrument can be used for monitoring. These instruments can accurately measure the water content in the air, helping users to find and deal with the problem of excessive water content in time. At the same time, according to the specific use environment and working conditions (such as the humidity of the inhaled air and the outlet temperature of the air compressor), the addition of cooling dryer or adsorption dryer and other measures can also effectively reduce the air moisture content of the air compressor.
