Two stage compression screw machine: how to select a two-stage compression screw machine? Comps compressor will introduce it to you
Now we often see double screw compressors in factories, but many people still don't know how to choose an air compressor with good performance. Let's follow comps compressor for details.
The air quality is determined by the user's requirements for air drying grade and pollution grade. It can save a lot of cost to truly meet the requirements of drying grade and pollution grade to meet the production requirements. In this way, it can avoid purchasing machines and screw air compressor models that exceed the actual production demand, so as to achieve the purpose of cost saving.
However, how to calculate the amount of air compressor required for the air source in the air system? The total amount is determined by your compressed air application equipment and processing device. The total air demand is not the sum of the demands of all components, but the sum of the average demands of each piece of equipment.
When calculating the small exhaust pressure demand, we need to take into account the different pressure levels and pressure drops of the compressed air equipment. Compressed air enters from one part to another, and the pressure in the equipment decreases accordingly. Some people often make a wrong judgment that the air compressor pressure is too low or unstable, and that it is caused by insufficient exhaust pressure.
The air pressure will decrease from the air compressor exhaust port to the actual terminal application position. The process of compressed air flowing in the system is accompanied by the generation of pressure drop. However, if the pressure drop is too large, it will lead to poor gas use effect and increase additional energy consumption. This should be noted in actual production.
Another key to the rational design and operation of screw air compressor system is to analyze the compressed air demand of the plant from the overall situation. In the long run, the change of air demand is a problem that can not be ignored in system design. Some factories have high requirements for the variability of air demand, and users need to scientifically design a set of schemes to meet their own needs.
