Air compressor is among the general products in manufacturing sector. It’s important for enterprises to accomplish a good work in energy-saving administration of atmosphere compressor. To be able to increase production cost, it is urgent for enterprises to set up high efficiency air compressors. So how to save lots of energy for air flow compressor? This paper summarizes eight common means of saving energy for atmosphere compressor, wishing to greatly help Motorbase energy-eating enterprises attain the purpose of saving power and reducing consumption.

For the air compressors which have been listed in the national elimination catalogue of high energy consumption equipment and have low energy efficiency, it is necessary to consider the entire renewal of new air compressors with high energy performance.

1, governance leaks.

According to the calculation, a 1 mm2 orifice leaks about 1.5 L/S under 7 bar pressure. Examine all pipeline systems and gas points, especially joints and valves, and deal with leakage factors in time.

2, pressure drop governance.

Pressure gauges are setup to measure pressure through pipeline sections, and pressure drop of every section is checked in detail, and the troubled pipeline sections are checked and maintained with time. General surroundings compressor wall plug to the gas stage, pressure drop cannot go beyond 1 bar, strict or actually only 10% that is 0.7 bar, cold-dried out filter section pressure drop is normally 0.2 bar. Factory layout so far as feasible annular pipe network, balance each stage with surroundings pressure.

3, change the pressure matching of gas devices.

Evaluate the pressure requirements of the gas equipment, and minimize the exhaust pressure of the air flow compressor when the production is guaranteed. The exhaust pressure of the surroundings compressor decreases by 1bar and the energy saving is approximately 7~10%.

4, adjust irrational usage of gas behavior.

Regarding to authoritative data, the energy utilization rate of surroundings compressor is only on the subject of 10%. About 90% of surroundings compressor is changed into heat energy reduction. It’s important to judge the pneumatic gear for factory make use of and whether it could be solved by electrical method. At the same time, we must resolutely end the routine washing work with compressed air.

5, adopt centralized control mode.

If the amount of air compressors is small, one variable frequency air compressor can be used to modify the pressure. If the quantity is large, centralized linkage control can be used to avoid the stepped exhaust pressure rise due to the parameter placing of multiple surroundings compressors.

6, do a good work in apparatus maintenance and cleaning.

Increase the temperature dissipation aftereffect of the air flow compressor, the exchange effect of the heat exchanger such as water cooling and air flow cooling, and maintain the essential oil quality.

7, the waste heat recovery of atmosphere compressor.

Recovery of surroundings compressor essential oil is used to prepare hot water for other processes or auxiliary living facilities.

8. Modification of drying system.

The brand new drying equipment uses air pressure air residual heat to dried out and dehydrate compressed air, and the energy conservation rate exceeds 80%.
