Is the air blown out by the air compressor normal?

It is normal that the air blown out by the air compressor has water.. The following is a detailed explanation of this phenomenon:

causes of 1. moisture

1. humidity in the air: The air in its natural state always contains a certain amount of moisture, the so-called humidity. When the air is compressed, the water will tend to saturated state until supersaturated, thus precipitating into liquid water.
2. Compression process of air compressor: During the compression process of the air compressor, the internal temperature of the compressor head is very high because the gas is compressed and releases a large amount of heat. Inhaling the moisture in the natural air will form water vapor during the compression process of the air compressor and discharge it with the compressed air.
3. cooling and condensation: Generally, the air compressor unit is equipped with an air cooler to forcibly cool the compressed air that is ready to be discharged from the air compressor. The purpose is to use the cooling and condensation effect to remove part of the water in the compressed air. However, since the temperature of the pipes, air storage tanks, etc. is lower than the exhaust compressed air, the water vapor will condense into liquid water on these parts.

Effect of 2. moisture

1. impact on equipment: The water in the exhaust of the air compressor will cause corrosion in the pipeline and the air storage tank, increase the content of pollutants in the air, and adversely affect the downstream equipment. If the water in the exhaust gas deposits and forms ice in some environments, it may also cause the failure of pneumatic equipment and even cause danger during high-speed movement.
2. Impact on the production process when enterprises produce and use compressed air, there are requirements for its oil and water content. High water content will not only damage the equipment, but also adversely affect the production process. The compressed air of the screw air compressor contains more water and the condensed water on the pneumatic equipment will take away the lubricating oil, resulting in low efficiency of the equipment. Condensate water will also accelerate the wear of the valve in the pipeline, causing the failure or misoperation of the pneumatic control equipment, causing the pipeline and equipment to rust. There is also a risk of the line bursting if water freezes at the low point of the line.

3. solutions

1. regular drainage: The gas storage tank needs to be drained regularly to prevent liquid water from accumulating in the air compressor. It is recommended to drain at least once a day, especially in wet weather or winter, the number of drains should be increased.
2. Check and maintain equipment: Regularly check the working status of the filter system to ensure that the filter can effectively filter the moisture and impurities in the air. If the cold dryer does not work or does not work properly, it should be checked and repaired in time.
3. Installing air dryer: In order to further reduce the water content in the compressed air, an air dryer can be installed. The air dryer can effectively remove the moisture in the compressed air and improve the air quality.

To sum up, it is normal for the air compressor to have water, but it is necessary to reduce its impact on the equipment and production process through proper maintenance and maintenance.
