How to choose post-processing equipment for screw air compressors During the operation of the screw air compressor, post-processing equipment is indispensable. Without post-processing equipment, it is not a complete screw air compressor system. The post-processing equipment of the air compressor includes: cold dryer, air storage tank, filter For different screw air compressor models, the specifications and selection of post-processing equipment are different.
1. Air storage tank: The volume of the air storage tank should be determined according to the displacement of the screw air compressor, which is generally one-sixth of the displacement. 2. Precision filter: According to the precision of the precision filter, the classification is also different. Air compressor precision filters are usually divided into three levels: Q, P, and S. Except for special industries, general three-stage filters can basically meet user needs.
3. The processing capacity of the dryer should also correspond to the exhaust capacity of the screw air compressor. When the air equipment of the screw air compressor requires compressed air with a dryness of -70°C (dew point), the heating regenerative cold drying is generally used If the dry air around -40℃ is needed, the non-heat regenerative refrigeration dryer is generally used; when the air equipment requires a win-win dry air around -20℃, the refrigeration dryer is used. The lower the pressure dew point, the higher the quality, which can be selected according to the gas requirements of the enterprise. The post-processing equipment of the screw air compressor is very important. The use of compressed air in different industries requires the removal of water, oil and other impurities from the compressed air. The compressed air also needs to be cooled and stored to ensure the quality of the compressed air and For the reliability of the pneumatic system, the air compressor post-processing equipment should be correctly selected.
