Air compressor is among the general devices in manufacturing industry. It’s important for Oil-free Air Compressor enterprises to accomplish a good job 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 compressor? This paper summarizes eight common means of saving energy for atmosphere compressor, hoping to greatly help energy-eating enterprises attain the goal 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. Check all pipeline systems and gas factors, 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 surpass 1 bar, strict or also only 10% that is 0.7 bar, cold-dried out filter section pressure drop is normally 0.2 bar. Factory layout as far as feasible annular pipe network, balance each stage with surroundings pressure.
3, adjust the pressure matching of gas devices.
Evaluate the pressure requirements of the gas products, and reduce the exhaust pressure of the air flow compressor when the production is assured. 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 price of air compressor is only on the subject of 10%. About 90% of air compressor is changed into heat energy loss. 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 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 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 setting of multiple atmosphere compressors.
6, do a good work in gear maintenance and cleaning.
Increase the temperature dissipation aftereffect of the atmosphere compressor, the exchange effect of the heat exchanger such as water cooling and air flow cooling, and keep maintaining the essential oil quality.
7, the waste high temperature recovery of atmosphere compressor.
Recovery of air 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 dry and dehydrate compressed air, and the energy conservation rate exceeds 80%.
