Oil-free air compressor is a common air compression equipment, the basic principle is to compress the air to a high pressure state after release for a variety of industrial and commercial applications. Compared with traditional oil air compressors, oil free air compressors have higher environmental friendliness and reliability.
The basic principle of oil-free air compressor can be divided into the following aspects:
1. Air inhalation: oil-free air compressors are compressed by inhaling a large amount of free air. The air enters the machine from the external environment through the filter element, and the role of the filter element is to filter out impurities and pollutants to ensure that the air is clean and pure.
2. Compression process: Once the air enters the oil-free air compressor, it will be driven into the compression chamber.
In the compression chamber, a pair of rotating screws or blades shrink the air to high pressure through the power generated by rotation. The design of the screw or blade is critical to effectively push the air into a smaller and smaller volume, thereby increasing the compression ratio of the air.
3. Cooling: In the compression process, the air will be heated by the mechanical work and the heat of the compression process in order to protect the machine and ensure efficient operation, oil-free air compressors are usually equipped with cooling systems. The cooling system can be cooled by air or water to dissipate heat from the compressed air and reduce the temperature of the air for subsequent processing and use.
4. Separation: The compressed air may contain some oil molecules and other impurities. In order to remove these contaminants, oil-free air compressors are usually equipped with separators or filters. Their role is to separate oil molecules and impurities from the air to ensure the purity of the outlet gas.
5. Storage and release: Once the air has been compressed and treated, it will be stored in a storage tank or container. These tanks can help balance the working load of the compressor and ensure a stable supply of air. When air needs to be used, the air in the tank is released and transported to the required location through the pipeline.
In general, the basic principle of oil-free air compressors involves many aspects such as air inhalation, compression, cooling, separation, storage and release. Through these processes, oil-free air compressors can compress free air to a high pressure state and ensure the purity and stability of the air. This makes oil-free air compressors indispensable in many industrial and commercial fields.
