(Summary description)The selection of the air compressor is very important to the air compressor equipment and the user itself. Too large selection is wasteful and expensive; too small selection may cause the air compressor to be in a loaded state for a long time, not enough air or pressure. and other disadvantages. Therefore, the selection of air compressors requires the correct and appropriate method. The expensive one is not necessarily the best, and the suitable one is the best.


1. The first thing to consider is the use of compressed air. As we all know, compressed air is widely used in production work in all walks of life, and different industries have different uses of compressed air.

2. The minimum operating pressure and the required amount of compressed air per minute. According to statistics, every 1kg increase in pressure consumes 7% more power.

3. Gas demand. If the gas production of the air compressor is too small, and the gas production is less than the gas consumption, the air compressor will always be in a loaded state, which will cause huge energy consumption.

4. Select and configure different types and grades of dryers and precision filters according to different gas quality. Poor quality will affect the quality of gas equipment and final products.

5. Considering the size of the air compressor station, ventilation and heat dissipation conditions, noise isolation, waste heat, waste water recycling, etc., will cause energy use.

6. As for the cooling method, there are mainly two kinds of air cooling and water cooling. Air cooling is a commonly used cooling method. It is not necessary to invest additionally in a cooling water tower, but it must have good ventilation conditions. It is generally used in small and medium-sized enterprise users; while the water-cooled model requires the establishment of a water tower, and its operating temperature is not affected by the environment. It is beneficial to the life of the air compressor, but it has the shortcomings of freezing, bursting and blocking, and is generally used in relatively large machines.

7. The stability of power supply planning, voltage demand and voltage drop must be required. The centrifuge is usually at high voltage and cannot be moved at all. When it starts, it will cause an impact on the power grid and should be kept in regular operation.
