There is water at the end of the compressed air.

The phenomenon of moisture accumulation at the end of compressed air is mainly caused by the following five factors:

1. the water vapor originally contained in the ambient humidity penetrating
   air is sucked into the compressor. During the compression process, the temperature rises. When the compressed air passes through the cooler or pipe, the temperature drop causes the water vapor to condense into liquid water.

2. Compression process condensation effect
   When the gas is compressed, the water vapor content per unit volume is relatively increased, when the pressure increases, the water vapor saturation increases, in the subsequent cooling link (such as gas storage tank or pipeline) beyond the saturation point, the formation of condensed water.

3. the gas storage equipment accumulated water is not discharged
   . The gas storage tank is used as a buffer container for compressed air. Condensed water will be generated in the gas storage tank due to temperature changes. If the accumulated water at the bottom of the tank is not discharged on a fixed basis, the water will enter the subsequent pipeline with the air flow.

4. if the drying equipment fails or the selection is improper
   , the processing capacity of the rear dryer (such as refrigeration dryer or adsorption dryer) is insufficient, or the equipment maintenance is not in place, resulting in the failure of the desiccant, which cannot effectively remove the residual moisture in the compressed air.

5. PIPING DESIGN OR INSTALLATION DEFECTS
   There is no drain valve at the low point of the pipe, or there is a U-bend in the pipe direction, which leads to the accumulation of condensate, and poor insulation of the pipe will aggravate the secondary condensation caused by the external cold air.

this phenomenon can be improved by optimizing the configuration of drying equipment, strengthening the drainage management of air storage tanks, perfecting the drainage design of pipelines and controlling the temperature of compressed air, so as to ensure that the air dryness at the end gas point meets the process requirements.
