The selection and configuration of air compressor includes the following basic principles: 1. The manufacturer of pneumatic equipment must be required to provide air consumption and gas consumption variation as the basis for analyzing and selecting the capacity of air compressor. 2. If there are seasonal, time difference or other factors that will affect the change of gas consumption, it is also necessary to evaluate and list in detail. If necessary, the corresponding countermeasures of air compressor suppliers or professionals can be consulted. 3. Consider the whole plant's forward-looking, and list the estimated gas consumption of short-term, medium-term and long-term investment plans respectively.

          In the case of a wide range of air consumption changes, choosing a compressed air system with both large and small capacity air compressors can provide a more flexible strain range. Of course, there will be unexpected energy saving effect. Several large capacity air compressors and half capacity small air compressors are configured. If the compressed air system with more than 3 ~ 5 air compressors is used, as long as the appropriate control mode and peripheral equipment are carefully selected, it is unnecessary to consider the compatible configuration of large and small capacity air compressors, so as to avoid the possibility of small capacity air compressors being idle.

          Different industries and factories have their own differences in the use of compressed air, so choosing the capacity of air compressor has a considerable degree of complexity, not as simple as adding a piece of furniture. This is related to the total cost of investment, including the energy cost, operation and maintenance cost, which accounts for the majority of the total investment,
