The humidity of the air changes as the temperature rises and falls, and the air compressor is also affected by the humidity of the air. When the air is compressed, its temperature rises and the relative humidity decreases. When the compressed air expands, the air temperature drops, the relative humidity increases, and water usually precipitates. If there is too much water in the air, what effect does it have on the air compressor?

1. Moisture in the working air narrows the compressed air passage and increases airflow resistance.
       2. Gas volumetric efficiency.
       3. It is not conducive to the air compression of the air compressor, so that the compression equipment and the pneumatic machine are subjected to hydraulic shock. If the cooler and cylinder contain more water, the machine is easily damaged. ;
       4. The moisture in the air is very corrosive, which will make the rust-prone compression equipment and pneumatic machinery shorten their service life.
5. If moisture is infiltrated into the air compressor lubricating oil, the machine will reduce the lubricating performance during the compression process, resulting in deterioration of the lubricating oil, increasing the wear between the parts, easily causing mechanical equipment failure, affecting its normal operation, and increasing the enterprise. Maintenance costs.
       6. One cubic meter of wet air (ie, the molecular density of air) is less than the dry weight of the same volume. At the same time, when compressed air passes through the cooler, most of the water vapor condenses and the ability to calculate weight decreases.
       7, the water supply system, when the temperature is below zero, the wall temperature will freeze, the smaller the diameter, the worse the situation, and sometimes even lead to a pipe completely frozen, will also affect the normal operation of the air compressor. Therefore, the quality of compressed air is not only related to its pressure, but also to humidity or other factors.
       Keep the temperature of the air compressor equipment normal, need to do the repair and maintenance work of the mechanical equipment, check regularly, find the problem and find a solution immediately, in order to ensure the normal and reliable operation of the air compressor.
