Atmosphere compressor is one of the general products in manufacturing industry. It’s important for enterprises to accomplish a good work in energy-saving management of atmosphere compressor. To be able to increase creation cost, it really is urgent for enterprises to set up high efficiency surroundings compressors. So how to save energy for surroundings compressor? This paper summarizes eight common ways of saving energy for surroundings compressor, hoping to greatly help energy-consuming enterprises attain the goal of saving energy and reducing intake.
For the air compressors which have been listed in the national elimination catalogue of high energy consumption equipment 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.
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 with time.
2, pressure drop governance.
Pressure gauges are set up 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 with time. General air flow compressor store to the gas point, pressure drop cannot go beyond 1 bar, strict or also only 10% that’s 0.7 bar, cold-dried out filter section pressure drop is normally 0.2 bar. Factory layout so far as possible annular pipe network, balance each stage with atmosphere pressure.
3, adapt the pressure matching of gas devices.
Measure the pressure requirements of the gas devices, and minimize the exhaust pressure of the air flow compressor when the production is guaranteed. The exhaust pressure of the surroundings compressor reduces by 1bar and the energy saving is approximately 7~10%.
4, adjust irrational usage of gas behavior.
According to authoritative data, the energy utilization rate of surroundings compressor is on the subject of 10%. About 90% of atmosphere compressor is converted to heat energy loss. It’s important to evaluate the pneumatic products for factory use and whether it could be solved by electrical method. At the same time, we should resolutely end the routine Shaft Collar 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 regulate the pressure. If the number is large, centralized linkage control can be used in order to avoid the stepped exhaust pressure rise due to the parameter placing of multiple air flow compressors.
6, do a good work in equipment maintenance and washing.
Increase the heat dissipation aftereffect of the air compressor, the exchange effect of heat exchanger such as for example drinking water cooling and air cooling, and maintain the oil quality.
7, the waste heat recovery of air compressor.
Recovery of surroundings compressor essential oil can be used to prepare hot water for other processes 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%.
