The air compressor is the basic product of industrial modernization. The air compressor is to provide the power of the air source. It is the core equipment of the pneumatic system, the main body of the electromechanical air source device. The most powerful device is an air pressure generating device for compressing air. Next, I will introduce the ten main principles of air compressor selection for you, and I hope it will be helpful to you!

1. Compressed air use.
2. The minimum operating pressure.
3. The required air volume at the tip and off-peak. If the difference between the highest and lowest operating pressure reaches 3bar, the “high and low pressure split” must be considered, and then different types of air compressors should be selected according to the peak and off-peak load changes. For example, the “base load” uses a centrifugal type (single machine> 75CMM) or screw type (single unit <60CMM): “fluctuating load” uses high-pressure air machines and large air storage tanks to cope.
4. Choose and configure different types and grades of dryers and precision filters according to different air quality. Excessive quality wastes energy, and insufficient quality affects the process, so it must be carefully considered.
5. The control technology of air compressors is changing with each passing day. Technologies such as “multi-machine chaining”, “frequency conversion and speed change” and “remote monitoring” can effectively suppress the waste of centrifugal BOV and spiral empty vehicles (saving 25-40% of electricity costs) , reduce standby capacity and investment (15-30%), and stabilize gas supply pressure (plus or minus 0.1bar).
6. The operating efficiency should not only be compared with the nominal horsepower and air volume in the catalog, but the actual “performance curve” and “air volume per horse”.
7. The installation considers the size of the computer room space, ventilation conditions, noise isolation, waste heat, waste water recycling, etc. all affect the use of energy. In addition, “centralized” has lower installation, maintenance and control costs than “distributed”, and can also reduce peripheral equipment. regional market
8. As for the cooling method, there are two kinds of air cooling and water cooling. Air cooling does not require additional investment in cooling tower rainwater, but it must have good ventilation: water cooling means that the operating temperature is not affected by the environment, which is beneficial to the life of the air compressor. Disadvantages of icing bursting and blocking.
9. Power supply planning The voltage demand and the stability of the voltage drop must be required. The centrifuge is usually high-voltage and cannot be moved at all. It will cause impact on the power grid when it is started, and it should be kept in regular operation.
10. The maintenance machine room should have proper maintenance space and necessary lifting facilities and access channels. Engineering personnel and maintenance should also be given different maintenance professional training.
