Atmosphere compressor is among the general gear in manufacturing market. It’s important for enterprises to do a good job in energy-saving management of atmosphere compressor. To be able to increase creation cost, it really is urgent for enterprises to install high efficiency air flow compressors. So how to save lots of energy for atmosphere compressor? This paper summarizes eight common means of saving energy for atmosphere compressor, wishing to greatly help energy-eating enterprises attain the purpose of saving electric power and reducing consumption.

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

1, governance leaks.

Based on the calculation, a 1 mm2 orifice leaks about 1.5 L/S under 7 bar pressure. Examine all pipeline systems and gas factors, specifically joints and valves, and cope with leakage points with time.

2, pressure drop governance.

Pressure gauges are create to measure pressure through pipeline sections, and pressure drop of each section is checked in detail, and the troubled pipeline sections are checked and maintained in time. General atmosphere compressor wall plug to the gas point, pressure drop can not exceed 1 bar, strict or also only 10% that is 0.7 bar, cold-dry filter section pressure drop is normally 0.2 bar. Factory layout so far as possible annular pipe network, balance each point with air pressure.

3, adapt the pressure matching of gas devices.

Measure the pressure requirements of the gas devices, and reduce the exhaust pressure of the air flow compressor when the creation is assured. The exhaust pressure of the air compressor reduces by 1bar and the energy conservation is approximately 7~10%.

4, adjust irrational usage of gas behavior.

Regarding to authoritative data, the energy utilization price of air compressor is about 10%. About 90% of air compressor is changed into heat energy reduction. It is necessary to judge the pneumatic devices for factory make use of and whether it can be solved by electrical method. Simultaneously, we should resolutely end the routine cleaning 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 regulate the pressure. If the number is large, centralized linkage control can be utilized to avoid the stepped exhaust pressure rise due to the parameter placing of multiple atmosphere compressors.

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

Increase the warmth dissipation effect of the air flow compressor, the exchange aftereffect of heat exchanger such as for example water cooling and air flow cooling, and keep maintaining the essential oil quality.

7, the waste temperature recovery of air compressor.

Recovery of air flow compressor oil is used to prepare warm water for other procedures or auxiliary living services.

8. Modification of drying system.

The new drying equipment uses air pressure air residual heat to dry and dehydrate compressed air, and the energy saving rate exceeds 80%.
