Air compressor energy saving elements
1. Replace the piston machine
Although the industry has entered the screw machine era for nearly two decades, at present, the domestic air compressor is the most used piston machine. Compared with the traditional piston compressor, the screw air compressor has the advantages of simple structure, small volume, higher reliability, stability and simple maintenance. The market share of screw air compressors has increased year by year. Especially in recent years, energy-saving screw compressors have emerged, and various companies are competing to launch products that are higher than the national energy efficiency rating standards.
2. Governance leaks
The average leakage of compressed air in the factory is as high as 20~30%, so the primary task of energy saving is to control leakage. All pneumatic tools, hoses, fittings, valves, a small hole of 1 square millimeter, under the pressure of 7bar, almost 4,000 yuan a year. It is imperative to check the leakage of the air compressor pipeline and optimize the design of the pipeline.
3. Pressure drop treatment
A pressure gauge is set up in each section of the pipeline. Generally, the air compressor is exported to the factory. The pressure drop cannot exceed 1 bar, and the stricter one cannot exceed 10%, that is, 0.7 bar. The pressure drop of the cold-drying filter section is generally 0.2 bar. The pressure drop of each section is inspected in detail, and problems must be maintained in time. (Each increase in pressure by one kilogram increases the energy consumption by 7%-10%).
