The difference between air-cooled and water-cooled screw air compressors

The difference between air-cooled screw machine and water-cooled screw machine: 　　The oil cooler of the air-cooled screw compressor and the compressed air after-cooler are made into one body. It is an aluminum plate-fin structure and brazed in a vacuum furnace. Once the oil leaks, it is almost irreparable and only replaced. The working principle is that hot oil and high temperature (about 80℃) gas flow in their respective pipes,

The basic theoretical knowledge of air that everyone who uses an air compressor should understand

1 What is air? What is normal air? 　　 Answer: The atmosphere around the earth, we are accustomed to call it air. 　　The air under the specified pressure of 0.1MPa, temperature of 20°C and relative humidity of 36% is normal air. Normal air is different from standard air in temperature and contains moisture. When there is moisture in the air, once the moisture is separated, the air volume will be reduced.
