In order to improve the operating efficiency of the air compressor and carry out effective energy-saving transformation, the following measures can be taken:

1.Equipment technology transformation: Consider using efficient screw air compressors to replace traditional piston air compressors, because screw air compressors have the advantages of simple structure, small size, higher reliability, stability and simple maintenance.

2.Leakage control: The leakage of compressed air in a factory may be as high as 20-30%. Therefore, checking the leakage of air compressor pipelines and optimizing the pipeline design are the top priorities for energy saving.

3.Pressure drop control: Install pressure gauges at each section of the pipeline to ensure that the pressure drop from the air compressor outlet to the factory use point does not exceed 1 bar. More strictly, it cannot exceed 10%, that is, 0.7 bar.

4.Equipment selection: Based on the gas consumption of the enterprise, considering the peak and trough periods of gas consumption, the use of efficient permanent magnet variable frequency screw air compressor is beneficial to energy saving.

5.Centralized control: In the era of Internet big data, multiple devices adopt centralized linkage control to avoid the step-by-step exhaust pressure increase caused by the parameter setting of multiple air compressors and reduce energy waste.

6.Lower the air intake temperature of the air compressor: The air compressor is usually placed indoors, so outdoor air intake can be considered. At the same time, increase the heat dissipation effect of the air compressor, maintain oil quality, and reduce energy loss.

7.Waste heat recovery: Air compressor waste heat recovery can use efficient waste heat recovery equipment to absorb the waste heat of the air compressor to heat cold water, without additional energy consumption, saving a lot of energy for the enterprise.

8.Frequency conversion energy saving: adopt frequency conversion speed regulation to change the running speed of the air compressor, reduce the motor shaft power output and reduce energy waste.

9.Soft start energy saving: Use frequency conversion energy saving device and the soft start function of the inverter to reduce the current impact at startup and extend the life of the equipment.

10.Power factor compensation: reduce reactive power, increase grid active power, and improve equipment efficiency.

By implementing the above measures, the operating efficiency of the air compressor can be significantly improved, energy consumption reduced, and the goal of energy saving and consumption reduction achieved.
