Air flow compressor is among the general tools in manufacturing industry. It is necessary for enterprises to do a good work in energy-saving management of surroundings compressor. In order to increase creation cost, it really is urgent for enterprises to install high efficiency atmosphere compressors. So how to save lots of energy for surroundings compressor? This paper summarizes eight common means of conserving energy for surroundings compressor, wishing to help energy-eating enterprises achieve the purpose of saving electric power and reducing intake.
For the air compressors which have been listed in the national elimination catalogue of high energy consumption apparatus and also have low energy efficiency, it’s important to consider the overall renewal of new air compressors with high energy efficiency.
1, governance leaks.
Based on the calculation, a 1 mm2 Coupling orifice leaks on the subject of 1.5 L/S under 7 bar pressure. Check all pipeline systems and gas factors, especially joints and valves, and deal with leakage factors with time.
2, pressure drop governance.
Pressure gauges are setup to measure pressure through pipeline sections, and 
pressure drop of each section is checked at length, and the troubled pipeline sections are checked and maintained in time. General atmosphere compressor wall plug to the gas point, pressure drop cannot surpass 1 bar, strict or actually no more than 10% that’s 0.7 bar, cold-dried out filter section pressure drop is normally 0.2 bar. Factory layout as far as possible annular pipe network, balance each point with surroundings pressure.
3, change the pressure matching of gas products.
Evaluate the pressure requirements of the gas tools, and reduce the exhaust pressure of the air flow compressor when the production is guaranteed. The exhaust pressure of the atmosphere compressor reduces by 1bar and the energ
y conservation is about 7~10%.
4, adjust irrational utilization of gas behavior.
Regarding to authoritative data, the energy utilization rate of atmosphere compressor is about 10%. About 90% of surroundings compressor is converted to heat energy loss. It is necessary to evaluate the pneumatic apparatus for factory make use of and whether it could be solved by electrical method. Simultaneously, we should resolutely put an end to the routine cleaning work with compressed air.
5, adopt centralized control mode.
If the number of air compressors is small, one variable frequency air compressor can be utilized to modify the pressure. If the quantity is large, centralized linkage control can be utilized to avoid the stepped exhaust pressure rise caused by the parameter placing of multiple air compressors.
6, do a good work in apparatus maintenance and cleaning.
Increase the high temperature dissipation aftereffect of the air compressor, the exchange aftereffect of heat exchanger such as drinking water cooling and air cooling, and keep maintaining the essential oil quality.
7, the waste warmth recovery of surroundings compressor.
Recovery of air compressor oil is utilized to prepare hot water for other procedures 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 saving rate exceeds 80%.
