In fields such as biology, medicine, electronics, food, medical, automobile, chemical industry, etc., the water, oil, dust and bacteria in the compressed air are required to reach a high quality level, but the water, dust and bacteria in the compressed air can all be It is solved by a series of post-processing equipment such as filters and dryers, and oil removal is relatively difficult, but we have some misunderstandings about oil-free air compressors and the compressed air they produce.
1. The compressed air produced by an oil-free air compressor is oil-free, which is not certain.
Although no oil is used in the compression chamber, the oil will not come into contact with the compressed air, but the oil vapor contained in the atmosphere itself cannot be removed, which makes the compressed air still contain a small amount of oil impurities. The oil content in the compressed air produced by the oil-air compressor has a very close relationship with the air quality, the environment of the air compressor room, and the cleanliness of the compressor.
2. Oil-free air compressors do not use oil, which is not correct.
Although oil is not used in the process of compressing air to come in contact with air, oil is still used to cool the compressor and lubricate the operating parts, so that the compressor can operate normally and stably.
3. The compressed air produced by the oil-free air compressor is pollution-free and pure. This is a wrong idea.
There are actually many pollutants in the atmosphere, including dust, water vapor, oil vapor, and microorganisms. The compressed air produced by the oil-free air compressor can only ensure that no oil is brought into the compressed air during the compression process, but it cannot remove the air itself. This means that the compressed air produced by an oil-free compressor is not necessarily pollution-free, and the use of air treatment products can help reduce pollution to the required air quality level.
4. Oil-free air compressors do not require air treatment products. On the contrary, the higher the air quality, the oil-free air compressors must also be equipped with post-processing systems.
It can be seen from the third point that the gas quality of compressed air produced by oil-free air compressors is largely restricted by the environment. Therefore, users need to configure corresponding post-processing equipment according to their own requirements for compressed air quality to meet their own needs. Demand for compressed air quality.
5. The application and maintenance cost of oil-free screw air compressor is low.
In fact, because the compression ratio is much smaller than that of oil-lubricated compressors, oil-free machines consume more energy. Oil-free machines with the same power can produce more than 40% less air than energy-saving screw compressors. Although the compression chamber is not lubricated by oil, But the grease and air filter in other parts still need regular maintenance. The core rotor is generally treated with a special coating and has a service life. It has high requirements for water and is easily damaged. The maintenance of the main engine is a necessary option for an oil-free machine. The high cost can account for 50% of the equipment cost.
We believe that for most users, it is not actually necessary to really need 0 grade oil-free compressed air, but more to solve the problem of oil impurities. For mid-range equipment: refrigerated dryers, heatless regeneration dryers, micro-heat regeneration Dewatering equipment such as dryers is a choice to prevent the efficiency of post-treatment equipment from decreasing or even losing the dewatering function. For users who really need Grade 0 oil-free compressed air, it is difficult to obtain oil-free compressed air continuously and stably by using an oil-free air compressor alone. It is still necessary to match the corresponding oil-removing post-processing equipment for oil-removing and filtering. To achieve the required compressed air quality.
