An oil-free air compressor is a device that uses non-lubricating materials for compression and gas. Compared to traditional lubricated air compressors, oil-free air compressors have lower maintenance costs, higher reliability and cleaner gas generation.
The working principle of oil-free air compressor is based on physical principles and design concepts. The following will introduce the working principle of oil-free air compressor in detail.
Entry of compressed air: The work of oil-free air compressors begins with the entry of air. When the air enters the air compressor through the air intake, it first passes through a pre-filter to remove large particles of dust and impurities. The air then enters the main body through the intake valve.
2. Compression process: After entering the main part, the air is guided into the compression chamber. Oil-free air compressors usually use screw or blade compressors to achieve air compression. Screw compressors generate compression by rotating screw, while blade compressors compress air by rotating blades. In the compression chamber, the air is gradually compressed and the pressure is gradually increased.
(3) Heat generation and discharge: During the compression process, due to the compression of air, collisions between molecules occur, resulting in an increase in temperature. In order to keep the operating temperature of the compressor within an acceptable range, oil-free air compressors are usually equipped with cooling systems, such as cooling fans or cooling pipes. These cooling systems can effectively reduce the temperature of the compressor and expel the heat generated.
4. Separation of gas and water: During the compression process, the water in the air will also increase as the air is compressed. In order to maintain the dryness of compressed air, oil-free air compressors are usually equipped with air dryers. The air dryer separates the water from the compressed air by adsorption or condensation to ensure that the subsequent air treatment process is not disturbed by water.
5. Gas filtration and treatment: After the compression and separation process, the compressed air needs to be further treated to meet the specific application requirements. Oil-free air compressors are usually equipped with filters and purifiers to remove airborne particles, oils, odors, and other pollutants. These filters and purifiers ensure the quality and purity of compressed air to meet the requirements of different applications.
6. Storage and distribution of compressed air: Finally, compressed air is stored in gas storage tanks and distributed to various equipment and processes through piping systems. The storage tank can provide a stable storage pressure and release compressed air supply to different equipment when needed.
In summary, oil-free air compressors compress, treat and distribute air through various physical principles and processes. Through proper design and configuration, oil-free air compressors can provide high-quality, reliable compressed air to meet the needs of a variety of industrial and commercial applications.
