The function of the air supply system is to continuously supply the pressure required by the salt spray test chamber and the clean/wet hot air. In this system, a 0.2m3 low-noise air compressor is planned to be used as a gas supply source. Purchase a 0.3m3 compressed air storage tank to store the gas, so as to avoid the direct gas supply affecting the life of the compressor, and supply the gas as needed. After the ambient atmosphere is compressed into high-pressure air by the air compressor, the air must first be oiled. Separation.
In order to ensure that the air entering the nozzle is clean and humid air, the gas produced by the compressor needs to be separated from the oil and water. In order to achieve separation and separation, the primary separator is a circular pressure vessel, which is active. Carbon / clean stone / wool felt shunt / sewage interface. The second stage is a fine filter, placed in front of the saturator, and strive to do the best to remove oil.
Since the spray pressure only needs 0.07~0.15MPa, the air after filtration and drying needs to be depressurized twice, the first stage reduces the air to 0.2-0.3MPa, and the second stage adjusts to 0.07~0.15MPa according to the amount of fog. The spray pressure ejected through the nozzle is within a predetermined range. 
For the ring test industry, there are many kinds of products classified. I believe that everyone is familiar with the salt spray test chamber. When you see this article, will you feel that the salt spray laboratory is still a bit strange in your own field of thought? What about it? Yes, the general industry uses a lot of salt spray test chambers, so it is not surprising if you feel strange. Now let us explain the gas supply system of the salt spray test room.
