The application range of air compressors is very wide. Nearly 80% of industries will be applied to air compressors. As air compressor technology becomes more and more mature, "energy saving and power saving" has become the first choice for everyone to buy air compressors.
When purchasing an air compressor, many buyers regard price as the primary criterion for purchasing an air compressor. In fact, the price factor is only a point of reference, and whether the air compressor is energy-saving is also very important.
"Specific power" is one of the important indicators for judging whether an air compressor is energy-saving. Specific power refers to the input power consumed by the air compressor to compress 1m3/min of air.
-Generally speaking, the total load power is divided by the unit displacement. The lower the specific power, the more energy-saving the machine under the same pressure. Therefore, the lower the input "specific power", the more energy-saving the air compressor.
GB19153-2009 "Limited Values and Energy Efficiency Grades of Positive Displacement Air Compressors"
According to the specific power, the energy efficiency standards of air compressors are divided into three levels:
First-level energy efficiency is the leading technology level;
The secondary energy efficiency is the domestic average level;
Level 3 energy efficiency is the industry's lowest threshold;
The energy efficiency lower than the third level does not meet the market access standards and cannot be sold.
According to the "Energy Efficiency Labeling Management Method", air compressor producers and importers can use their own testing laboratories or entrust third-party inspection and testing institutions that have obtained qualifications according to law to test their products and comply with the mandatory national standards for energy efficiency. Determine the energy efficiency rating of the product.
Specific power=input power÷exhaust volume
For example, a screw air compressor with a gas output of 6 cubic meters per minute and a working pressure of 8 kilograms of -37KW, after inspection, is classified as first-class energy efficiency; between 7.3-8.1 is classified as second-class energy efficiency, and between 8.2-8.9 is Level 3 energy efficiency, greater than 8.9 is a super power-consuming product, and the country does not allow production. (Note: you can go to the official website of China Energy Efficiency Labeling website for air compressor manufacturers that meet the standard)
For example, a 6 cubic air compressor, one manufacturer’s standard specific power is 7.1Kw/m3/min (first-level energy efficiency), and the other air compressor manufacturer’s standard is 8.6Kw/m3/min (third-level energy efficiency), Then the first-level energy-efficiency air compressor saves electricity per hour than the third-level energy-efficiency air compressor = (8.6-7.1)*6=9 kilowatt-hours of electricity, according to industrial electricity 1 yuan per kilowatt, it works 10 hours a day and works for a year 300 days, then a year can save 9*10*300=27000 yuan.
