Air flow compressor is among the general equipment in manufacturing industry. It is necessary for enterprises to do a good work in energy-saving Energy-conserving Vacuum Pump management of air compressor. To be able to increase creation cost, it is urgent for enterprises to install high efficiency atmosphere compressors. Just how to save lots of energy for air flow compressor? This paper summarizes eight common ways of saving energy for air compressor, hoping to greatly help energy-consuming enterprises achieve the purpose of saving electricity and reducing consumption.

For the air compressors that have been listed in the national elimination catalogue of high energy consumption gear and have low energy efficiency, it’s important to consider the overall renewal of new air compressors with high energy performance.

1, governance leaks.

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

2, pressure drop governance.

Pressure gauges are set up 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 with time. General atmosphere compressor wall plug to the gas point, pressure drop cannot surpass 1 bar, strict or also no more than 10% that’s 0.7 bar, cold-dry filter section pressure drop is generally 0.2 bar. Factory layout as far as possible annular pipe network, balance each point with surroundings pressure.

3, modify the pressure matching of gas devices.

Measure the pressure requirements of the gas devices, and reduce the exhaust pressure of the air compressor when the production is assured. The exhaust pressure of the surroundings compressor reduces by 1bar and the energy saving is about 7~10%.

4, adjust irrational utilization of gas behavior.

Regarding to authoritative data, the energy utilization price of atmosphere compressor is only about 10%. About 90% of surroundings compressor is changed into heat energy reduction. It’s important to evaluate the pneumatic tools for factory use and whether it can be solved by electric method. Simultaneously, we must resolutely put an end to 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 utilized in order to avoid the stepped exhaust pressure rise caused by the parameter placing of multiple atmosphere compressors.

6, do a good work in apparatus maintenance and washing.

Increase the temperature dissipation effect of the air compressor, the exchange aftereffect of the heat exchanger such as drinking water cooling and air cooling, and keep maintaining the oil quality.

7, the waste warmth recovery of surroundings compressor.

Recovery of atmosphere compressor essential oil is utilized to prepare warm 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 dry and dehydrate compressed air, and the energy saving rate exceeds 80%.
