Air compressor has been widely used in industry for more than one hundred years. From the first piston machine point to open the technology tree for compressed air, then the slide machine came out, and then the screw machine presented the application of 100 cubic exhaust centrifuge, the technology evolution has never stopped. Since the screw air compressor came out in the 1960s, because of its outstanding advantages such as low noise, high energy efficiency, low defect rate and so on, it has been widely recognized by customers as soon as it was introduced into the market. At present, screw air compressor has occupied the dominant position in the market below 100 cubic meters of compressed air exhaust volume, and replacing piston machine application has been unstoppable.
Oil content in compressed air is an unavoidable phenomenon of many kinds of air compressors. Smooth oil is necessary for most air compressors to operate. Smooth oil basically participates in the whole process of compressed air, so oil content in compressed air is an objective fact. Screw air compressor is divided into two categories: fuel injection and oil-free. Because smooth oil participates in the whole air compression process of screw main engine, Yin and Yang rotors rely on smooth oil to smooth, seal and cool during high-speed rotation to ensure long-term use of equipment.
Therefore, the role of smooth oil in fuel injection screw air compressor is irreplaceable. In order to solve the problem of oil content in compressed air, the mainstream brands Atlas Copco, Ingersolan, Drea and Brett have perfect and reliable high-efficiency oil and gas separation system to ensure that the oil content of compressor outlet compressed air is controlled within 3PPM.
Compressed air with higher quality in the compact air system can be further enhanced through fine pipeline filters. Shanghai Ouenyou Compressed Air Post-disposal System has a patented multi-layer fiber composition high-efficiency filter, which can filter most of the oil vapor up to 0.003 MP level. In some special industries, oil-free screw air compressors are required to be purchased if the compressed air is oil-free. At present, oil-free screw air compressors have excellent performance and advanced technology. They use food-grade pure water instead of smooth oil, and use all stainless steel parts to ensure the operation of the machine. Because the high quality of oil-free screw air compressors is medicine and medicine. Food, high-end textile, electronics and other high-end manufacturing industries, one of the preferred brands of air compressors.
