Air compressor is one of the general tools in manufacturing sector. It is necessary for enterprises to accomplish a good work in energy-saving administration of air compressor. In order to increase creation cost, it is urgent for enterprises to install high efficiency air compressors. Just 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-consuming enterprises accomplish 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 gear and also have low energy efficiency, it’s important to consider the entire renewal of new air compressors with high energy efficiency.
1, governance leaks.
According to the calculation, a 1 mm2 orifice leaks about 1.5 L/S under 7 bar pressure. Verify all pipeline systems and gas factors, specifically joints and valves, and handle leakage points in 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 store to the gas stage, pressure drop cannot exceed 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 so far as feasible annular pipe gear motor for greenhouse network, balance each stage with surroundings pressure.
3, adjust the pressure matching of gas devices.
Measure the pressure requirements of the gas products, and minimize the exhaust pressure of the air flow compressor when the production is guaranteed. The exhaust pressure of the atmosphere compressor decreases by 1bar and the energy conservation is about 7~10%.
4, adjust irrational utilization of gas behavior.
Regarding to authoritative data, the energy utilization price of atmosphere compressor is on the subject of 10%. About 90% of surroundings compressor is converted to heat energy reduction. It is necessary to evaluate the pneumatic gear for factory use and whether it could be solved by electrical method. At the same time, we must resolutely put an end to the routine washing work with compressed air.
5, adopt centralized control mode.
If the number of air compressors is small, one variable frequency air compressor can be used to modify the pressure. If the number 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, execute a good job in devices maintenance and washing.
Increase the temperature dissipation effect of the atmosphere compressor, the exchange aftereffect of heat exchanger such as for example drinking water cooling and surroundings cooling, and maintain the essential oil quality.
7, the waste warmth recovery of air compressor.
Recovery of surroundings compressor essential oil is used to prepare warm water for other procedures or auxiliary living facilities.
8. Modification of drying system.
The new drying equipment uses air pressure air residual heat to dried out and dehydrate compressed air, and the energy saving rate exceeds 80%.
