Air flow compressor is among the general equipment in manufacturing sector. It's important for enterprises to do a good job in energy-saving administration of surroundings compressor. To be able to increase creation cost, it is urgent for enterprises to install high efficiency surroundings compressors. Just how to save lots of energy for surroundings compressor? This paper summarizes eight common means of conserving energy for air flow compressor, hoping to greatly help energy-consuming enterprises accomplish 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 tools and have low energy effectiveness, it is necessary to consider the entire renewal of new air compressors with high energy effectiveness.

1, governance leaks.

Based on the calculation, a 1 mm2 orifice leaks about 1.5 L/S under 7 bar pressure. Examine all pipeline systems and gas factors, specifically 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 every section is checked in detail, and the troubled pipeline sections are checked and maintained in time. General surroundings compressor outlet to the gas stage, pressure drop can not surpass 1 bar, strict or even only 10% that's 0.7 bar, cold-dried out filter section pressure drop is generally 0.2 bar. Factory layout so far as possible annular pipe network, balance each stage with air pressure.

3, adjust the pressure matching of gas equipment.

Evaluate the pressure requirements of the gas tools, and reduce the exhaust pressure of the air compressor when the production is guaranteed. The exhaust pressure of the atmosphere compressor reduces by 1bar and the energy saving is about 7~10%.

4, adjust irrational usage of gas behavior.

Regarding to authoritative data, the energy utilization rate of air flow compressor is only on the subject of 10%. About 90% of surroundings compressor is changed into heat energy reduction. It's important to judge the pneumatic devices for factory make use of and whether it can be solved by electrical method. Simultaneously, we should resolutely end the routine washing use compressed air.

5, adopt centralized control mode.

If the number of air compressors is small, one variable frequency air compressor can be utilized to regulate the pressure. If the number is huge, centralized linkage control can be utilized to avoid the stepped exhaust pressure rise due to the parameter placing of multiple air compressors.

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

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

7, the waste high temperature recovery of surroundings compressor.

Recovery of atmosphere compressor oil is used to prepare hot water for other Sprial Reducers processes or auxiliary living facilities.

8. Modification of drying system.

The new drying equipment uses air pressure air residual heat to dry and dehydrate compressed air, and the energy conservation rate exceeds 80%.
