After the air compressor is equipped with a cold dryer, there is air and water.

In the post-processing equipment of the screw air compressor, there are mainly air storage tanks, dryers and filters. Dry compressed air can ensure the operation of air compressor air system and production process.

The role of the dryer is to eliminate the condensed water in the compressed air and ensure the discharge of dry and clean compressed air. After being equipped with a related dryer, the compressed air still contains water because of these five reasons.

First, the air humidity around the air compressor station is high. The air itself has humidity and contains a certain amount of moisture. When the air is compressed, due to the high temperature inside the compressor, the moisture directly evaporates to form water vapor, and then discharges the compressor with pressure. When the compressor is stopped, the temperature drops, which will cause water vapor. Form condensed water. Therefore, the working environment humidity of the air compressor should be low; or the condensed water should be discharged before starting the machine.

Second, the post-treatment drying equipment fails. The general drying and post-processing capacity of the cold dryer is the pressure dew point of 3 ℃. If the temperature of your work site is lower than 3 ℃, there will be water. At this time, it is recommended to configure the post-treatment drying equipment of the micro-heat suction dryer, and the pressure dew point can reach -20 ℃ without water.

Third, the configuration of the post-processing drying equipment capacity is not enough. Generally speaking, the post-drying treatment capacity configured by the manufacturer for the user is configured according to the average gas consumption. If your instantaneous gas consumption is large, it will cause insufficient capacity of the post-processing drying equipment and cause water in the gas.

Fourth, the gas tank itself has the function of water accumulation, which contains a lot of water is not discharged, forget to drain. Regularly open the drain valve under the gas tank to drain the water.

Fifth, there is a problem with the pipeline design. The design slope of the compressed air pipeline is not enough, and the pipeline condensate is not discharged in time, which will cause water.
