When selling screw air compressors, only knowing these four elements can help customers make selections

The most important thing to analyze an air compressor air system is to determine your air compression needs, which includes the quality and quantity requirements of the end users in the factory. Careful evaluation of these requirements and a good understanding of the differences between the two can ensure that we can properly configure the air compressor system. In addition, determining your air pressure and loading requirements is also very important and cannot be ignored.

　　 The "Quality" of Air

　　 The air quality is determined by the user's requirements for the dryness and pollution levels of the air. Knowing the real drying level requirements and minimum pollution level requirements that meet the production requirements can save a lot of costs. In this way, it is possible to avoid purchasing machines and models that exceed actual production requirements in order to achieve cost savings.

　　The amount of air

　　 Then how to calculate how much air compressor is needed for the air source in the air system? This total amount is determined by your compressed air application equipment and processing equipment (load factor also needs to be taken into account). The total air demand is not the sum of the maximum demand of all components but the sum of the average demand of each piece of equipment.

　　 pressure demand

　　When calculating the minimum exhaust pressure requirement, we need to take into account the different pressure levels and pressure drops of the compressed air equipment. Compressed air enters from one component to another, and the pressure in the equipment is also reduced. Some people often make the wrong judgment that the air compressor pressure is too low or unstable, and that it is caused by insufficient exhaust pressure.

　　The meaning of pressure drop is: from the exhaust port to the actual terminal application position, the air pressure will decrease. The process of compressed air flowing in the system is accompanied by pressure drop. However, if the pressure drop is too large, it will result in poor air consumption and increase additional energy consumption. This must be paid attention to in actual production.

　　 load demand

　　 Another key to reasonable design and operation of the screw air compressor system is to analyze the compressed air demand of the factory from the overall situation. In the long run, changes in air demand are an issue that cannot be ignored in system design. Some factories have high requirements for the variability of air demand. Users need to scientifically design a complete set of efficient and energy-saving solutions to meet their own needs, such as using multiple air compressors to control in parallel to obtain the most economical operation mode.
