The air compressor system is a production auxiliary equipment or power equipment in the manufacturing industry, and its energy consumption reaches 10-60.66% of the total energy consumption of the enterprise;
The long service life of the air compressor causes the main engine to wear out, and the screw clearance increases. The air leakage also increases during the process of compressing the air, so that the exhaust gas volume is reduced, resulting in low equipment utilization rate;
The air compressor supplies air in parallel for multiple units of low power. The disadvantage of this arrangement is that each unit requires a separate post-processing and dry filtration system, and each unit will cause a certain pressure loss when it passes through an independent filtration system. , which will cause the pressure of the pipe network to be low and the pressure of the compressor supply to increase, the compressor load will increase, the power consumption will also increase, and the gas terminal will have insufficient gas supply;
The single-stage compression screw air compressor unit has high input specific power and low utilization rate, and is not a national energy-saving certification device;
According to China's “medium- and long-term energy conservation planning” and “12th Five-Year Plan for National Economic and Social Development”, energy-saving of compressed air system has become an important part of “Electrical System Energy Saving” in “Top Ten Key Energy-Saving Projects”.
