In the aftertreatment equipment of the screw air compressor, there are mainly a gas storage tank, a dryer and a filter. The dry compressed air ensures uninterrupted operation of the air compressor air system and production process.
The function of the dryer is to eliminate the condensed water in the compressed air and ensure the discharge of dry and clean compressed air. After the relevant dryer is equipped, but the compressed air still contains water, because of these five reasons.
1. High air humidity around the air compressor station
The air itself has humidity and contains a certain amount of water. When the air is compressed, the internal temperature of the compressor is high, the water directly evaporates to form water vapor, and then the pressure is discharged to the compressor. When the machine is shut down, the temperature drops, and the water vapor is caused. Condensed water is formed. Therefore, the working environment of the air compressor has a low humidity; or the condensate is discharged before being used.
2. Post-treatment drying equipment failure
The general cold drying machine has a post-drying capacity of 3 ° C. If your working site temperature is lower than 3 ° C, there will be water. At this time, it is recommended to configure the micro-drying dryer to process the drying equipment, and the pressure dew point can reach -20 °C without generating water.
3. Air compressor configuration of post-processing drying equipment is not enough
In general, the post-drying treatment that the manufacturer configures for the user is configured according to the average air consumption. If your instantaneous gas consumption is large, the capacity of the post-treatment drying equipment will be insufficient, resulting in water in the gas.
4. The gas tank itself has the function of accumulating water
It contains a lot of water that is not discharged, forgetting to drain. Regularly open the drain valve under the gas tank to drain the water.
