How to do a good job of energy saving air compressor

Air compressor is one of the general equipment in the manufacturing industry, and doing a good job of energy saving management of air compressor is a necessary work for enterprises to save electricity. In order to save the production cost of enterprises, enterprises equipped with high energy efficiency air compressor is imminent. So how to make the air compressor energy saving?

This paper summarizes the air compressor energy saving eight common paths, hoping to help the energy consumption of large enterprises to achieve the goal of saving electricity and reducing consumption.

For the list of high energy-consuming equipment that has been included in the national elimination and the air compressor with low energy efficiency, it is necessary to consider the overall renewal of the new air compressor with high energy efficiency.

1. Governance leakage

it is estimated that a 1mm small hole, under the pressure of 7bar, the leakage is about 1.5L/S, check all the transmission pipe network and gas points, especially joints, valves and other places, timely treatment of leakage points.

2. Pressure drop treatment

set up a pressure gauge to detect the pressure through the pipeline section, check the pressure drop of each section in detail, and check and maintain the pipe network section with problems in time. Generally, the pressure drop from the outlet of the air compressor to the gas consumption point cannot exceed 1bar, strictly even not exceeding 10%, I .e. 0.7bar, and the pressure drop of the cold and dry filter section is generally 0.2bar. The factory shall arrange the ring pipe network as much as possible to balance the gas pressure at each point.

3. Pressure matching of gas equipment for adjustment

assess the pressure requirements of the gas equipment, and reduce the air compressor exhaust pressure as much as possible under the condition of ensuring production. The exhaust pressure of the air compressor is reduced by 1bar, and the energy saving is about 7 ~ 10%.

4. Adjust unreasonable gas consumption behavior

according to authoritative data, the utilization rate of electric energy of air compressor is only about 10%, and about 90% is converted into heat energy loss. It is necessary to evaluate the pneumatic equipment used in the factory and whether it can be solved by electric mode. At the same time should also resolutely put an end to the use of compressed air to do routine cleaning work.

5. Adopt centralized control mode

if the number of air compressors is small, a variable frequency air compressor can be used to adjust the pressure. If the number is large, centralized linkage control can be used to avoid the step-by-step exhaust pressure rise caused by the parameter setting of multiple air compressors.

6, do a good job of equipment maintenance, cleaning

increase the air compressor heat dissipation effect, water cooling, air cooling and other heat exchanger exchange effect, keep the oil clean.

7. Waste heat recovery of air compressor

recycling the heat of the air compressor oil system to prepare hot water for use in other processes or assisted living facilities.

8. Modification or replacement of drying system

the new drying equipment uses the waste heat of air pressure to dry and dehydrate the compressed air, and the energy saving rate exceeds 80%.
