Screw air compressors There are three types of air pollutants, namely water, oil and dust. Moisture: It is inherent in natural air; oil: most of it comes from air compressor (small oil in the air in areas with severe air pollution); solid particles: partly from air Part of it comes from inside the compressed air system. With the development of modern industrial production technology, dry and purified compressed air has been widely used in various production fields, and at the same time put forward higher requirements for compressed air source quality. This requires us to strictly configure according to the requirements of compressed air and downstream compressed air. In order to achieve the goal, it is necessary to at least understand and fully consider the following points. The oil in the compressed air is weakly acidic, so it can not only play a role in lubricating the gas equipment, but will cause corrosion for a certain period of time. The inside will cause malfunction of the gas equipment. Although the injection screw air compressor has “oil separator” for oil and gas separation, the temperature of the compressed air entering the “oil separator” is higher, that is, the oil vapor. The pressure is also high, and the oil vapor cannot be completely separated in the “oil and gas separator”, and the quality of the oil core and the working condition of the compressor in actual operation are caused. The various factors, compressor, the amount of oil in the compressed air is sometimes not very low, and there will even be a gradual increase. Air compressor During the use, it may be necessary to add lubricating oil. However, if it is necessary to refuel frequently, it is caused by excessive fuel consumption. It is necessary to carry out the air compressor unit. Check to find out the cause of the malfunction and take action.
The oil content in compressed air is generally expressed in mg/m3 (ie, the oil content per cubic meter of compressed air), and also in ppmw (weight ratio) and ppmv (volume) Said). (1ppm/m3= 1mg/m3) causes the main cause of increased oil content in the air use system (compressor) The opening pressure of the pressure valve is low, and it is not guaranteed that the oil-gas mixture gas passes through the fine separator filter at a relatively normal flow rate, ensuring a good separation effect. Oil and gas separator filter quality compressor low pressure operation. The above reasons are most important for the quality of the oil separator filter. Of course, the design of the oil separator is also important, such as the upper intake, the lower intake structure, the loop flow rate, and the like. The suspended matter in the air is various, but it can be subdivided according to the size of the particles. All the suspended matter of the diameter <100μm is called "total suspended matter", and the suspension of the equivalent diameter ≤10μm is called “Respirable particulate matter”. The suspended matter in the flowing air does not easily settle and can settle slowly in still air. That is, the water content or dew point temperature requirements: different processes have different requirements for the dew point temperature of the compressed air. For example, the dew point of the compressed air pressure used as the instrument is generally required to be below -40 ° C, and the pressure dew point of the compressed air in the semiconductor chip factory. It may be required to be at -70 ° C, but in most cases, it is sufficient to require a dew point temperature of compressed air above 0 ° C. The dew point requirement for compressed air is usually achieved by a dryer.
