How to carry out energy-saving transformation for screw air compressor First of all, Hanos energy-saving screw air compressor is selected as the first class energy-efficient energy-saving air compressor. It saves 15% energy than the ordinary secondary energy-efficiency air compressor and 30% energy than the tertiary energy-efficiency air compressor. 2. Control the leakage. It is estimated that the leakage rate of a 1mm2 small hole is about 1.5L/s under the pressure of 7bar. Check all transmission pipe networks and gas consumption points, especially joints and valves, and deal with the leakage points in time. 3. Pressure drop control. Set up a pressure gauge to detect the pressure through the pipeline section, check the pressure drop of each section in detail, and timely check and maintain the pipe network section with problems. 

Generally, the pressure drop from the outlet of the air compressor to the gas consumption point should not exceed 1 bar, strictly not more than 10%, that is, 0.7 bar. The pressure drop of the cold-dry filtration section is generally 0.2 bar. The factory should try to arrange a ring pipe network to balance the gas consumption pressure at each point. 4. Adjust the pressure matching of gas equipment. Evaluate the pressure demand of gas equipment, and try to reduce the exhaust pressure of air compressor under the condition of ensuring production. When the exhaust pressure of the air compressor is reduced by 1 bar, the energy saving is about 7~10%. 5. Adjust unreasonable gas consumption behavior. 6. Adopt centralized control mode. If the number of air compressors is small, one variable frequency air compressor can be used for pressure regulation.

If the number is large, centralized linkage control can be used to avoid the stepwise exhaust pressure rise caused by the parameter setting of multiple air compressors. 7. Maintain and clean the equipment. Increase the cooling effect of air compressor and the exchange effect of water cooling, air cooling and other heat exchangers, maintain the oil quality and reduce the pressure difference 8. The waste heat recovery of air compressor is to recover the heat of air compressor oil system to prepare hot water for other processes or auxiliary living facilities.
