Atmosphere Shaft Collar compressor is among the general tools in manufacturing industry. It’s important for enterprises to do a good work in energy-saving administration of atmosphere compressor. To be able to increase creation cost, it really is urgent for enterprises to set up high efficiency air compressors. Just how to save lots of energy for air flow compressor? This paper summarizes eight common ways of conserving energy for air compressor, hoping to greatly help energy-consuming enterprises attain the goal of saving electric power and reducing intake.

For the air compressors which have been listed in the national elimination catalogue of high energy consumption devices and also have low energy performance, it’s important to consider the overall 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 networks and gas factors, specifically joints and valves, and deal with 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 in detail, and the troubled pipeline sections are checked and maintained in time. General atmosphere compressor outlet to the gas point, pressure drop can not exceed 1 bar, strict or also only 10% that’s 0.7 bar, cold-dried out filter section pressure drop is generally 0.2 bar. Factory layout so far as feasible annular pipe network, balance each stage with air flow pressure.

3, modify the pressure matching of gas tools.

Measure the pressure requirements of the gas apparatus, and reduce the exhaust pressure of the air flow compressor when the production is assured. The exhaust pressure of the air flow compressor decreases by 1bar and the energy conservation is approximately 7~10%.

4, adjust irrational use 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 reduction. It is necessary to evaluate the pneumatic products for factory make use of and whether it could be solved by electrical method. Simultaneously, we should resolutely put an end to the routine washing use compressed air.

5, adopt centralized control mode.

If the amount of air compressors is small, one variable frequency air compressor can be used to regulate the pressure. If the quantity is large, centralized linkage control can be used to avoid the stepped exhaust pressure rise caused by the parameter establishing of multiple surroundings compressors.

6, do a good work in gear maintenance and cleaning.

Increase the high temperature dissipation aftereffect of the air flow compressor, the exchange effect of the heat exchanger such as drinking water cooling and atmosphere cooling, and maintain the oil quality.

7, the waste warmth recovery of air flow compressor.

Recovery of air compressor oil can be used to prepare warm water for other processes or auxiliary living services.

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%.
