Oil-free air compressor is a kind of efficient and energy-saving air compression equipment, compared with the traditional lubricating air compressor, oil-free air compressor does not need to use lubricating oil, so it will not produce oil fog and pollution during operation, and will not cause waste of energy and human resources, so it is more and more widely used in industrial, scientific research and other fields.
The working principle of oil-free air compressor is mainly divided into two steps, namely compression and cooling. First of all, the oil-free air compressor inhales the external air through the air intake and compresses it through the compression chamber of the cylinder, so that the volume of the gas is reduced and the pressure is increased, thus forming a high-pressure gas. In this process, the oil-free air compressor uses a special cylinder structure and double sealing technology, so that the gas in the compression chamber is not in direct contact with the cylinder wall or piston, so as to achieve oil-free operation.
With the compression of gas, a lot of heat is generated, in order to ensure the normal operation of the oil-free air compressor and extend the life of the equipment, cooling measures must be taken. Therefore, a cooler is arranged between the compression chamber and the air outlet to cool the compressed gas to the set temperature, and the cooled high-pressure gas is discharged through the air outlet.

Oil-free air compressors are mainly composed of compressors, coolers, driving components and control systems. Compressor is the core component of oil-free air compressor, and its performance and structure directly affect the efficiency and stability of the entire equipment.
Because the oil-free air compressor has no lubrication system, its maintenance and maintenance during operation also has certain characteristics and difficulty. In order to ensure the normal operation of the equipment and extend the service life, it is necessary to regularly clean, check and maintain the equipment.
In short, the working principle of oil-free air compressor can be divided into two processes: compression and cooling, which have broad application prospects in industry, scientific research and other fields, but also need to pay attention to some special problems and difficulties in the use and maintenance process.
