The water in the air tank of the air compressor is mainly the water formed by the condensation of water vapor during the compressed air process. This water contains trace amounts of oil and fat, unlike ordinary tap water. The following is a detailed explanation:
source of Water
- water vapor in the air: The air always contains a certain amount of water vapor. When the humid air is compressed by the air compressor, the temperature and pressure will rise, and the water vapor will reach a supersaturated state, which will precipitate into liquid water.
- cooling condensation: When the compressed air enters the air storage tank, due to the rapid drop in temperature, the water vapor will further condense into water. The gas storage tank is a closed container. In a static state, due to gravity, this water will deposit on the bottom of the gas storage tank.
Characteristics of water
- contains trace amounts of grease: Since the air compressor will come into contact with lubricating oil during operation, the condensed water may contain trace amounts of grease.
- Impact on equipment: If the accumulated water in the gas storage tank is not discharged in time, it may cause corrosion inside the gas storage tank and affect the service life of the equipment. At the same time, the water may also enter the follow-up equipment with the compressed air, causing equipment failure or product quality problems.
Processing method
- regular drainage: In order to maintain the normal working condition of the gas storage tank, it is necessary to discharge the accumulated water in the gas storage tank regularly. This can usually be achieved by a drain valve at the bottom of the gas storage tank.
- Installing automatic drain: In some occasions with high air quality requirements, an automatic drain can be installed to automatically discharge the accumulated water in the air tank to improve work efficiency and air quality.
In summary, the water in the air tank of the air compressor is mainly condensed by water vapor in the compressed air process and contains trace amounts of grease. In order to maintain the normal operation of the equipment and air quality, these stagnant water need to be treated regularly.
