Analyzing the energy-saving secrets of air compressor inverters

1. After using the frequency converter, the pressure setting of the air compressor can be one point, that is, the pressure that meets the requirements of the production equipment can be used as the set pressure. The frequency converter will adjust the air compressor speed according to the trend of the pipe network pressure fluctuation, reducing the unloading operation of the air compressor and saving electricity.

2. Since the inverter in the system stabilizes the pressure on the upper and lower parts of the pipeline, the pressure fluctuation can be reduced or even eliminated, so that all the air compressors running in the system can operate at a lower pressure that meets the production requirements, reducing the power loss caused by the upward pressure fluctuation.

3. Since the air compressor cannot exclude the possibility of long-term operation under full load, the capacity of the motor can only be determined according to the greater demand, so the design capacity is generally larger. In actual operation, the proportion of light-load operation time is very high. If variable frequency speed regulation is adopted, the working efficiency during operation can be greatly improved. Therefore, the energy-saving potential of applying the inverter to the air compressor system is very large.

4. Some adjustment methods cannot reduce the operating power of the motor when the demand is small. After adopting variable frequency speed regulation, when the demand is small, the motor speed can be reduced, the motor operating power can be reduced, thereby further achieving energy saving.

5. After the air compressor adopts variable frequency speed regulation, it can be continuously adjusted according to the weight of the load, and can maintain the stability of parameters such as pressure, flow, temperature, etc., thereby improving working performance.
