Product advantages
Why two-stage compression is more energy-efficient than single-stage?
According to the working principle of compressor know, isothermal compression isone of the most province work. The curves for the compression process indicator diagram, below 12 '3' for the isothermal compression process, and the vertical form of area of 613"4 indicated work for isothermal compression. Curve 123 "as the primary compression process, and the vertical form of area of 613 4"as the level of compression instruction work.Curve 12,22,2 '3 for two stage compression process, and the vertical form of area is the sum of 6125 and 52' 34 (6122 '34) for the two stage compression indicated work. From here you can see that the isothermal
compression process 613 '4 minimum area (indicated work), but in actual compression process of the compressor can't isothermal
compression, level 13 more compression than isothermal compression' 3 "the power of the area, and two stage compression level of
compression than the power of 2 '23"3 area.

Two-stage compression energy saving case
1.250KW single-stage compressorion type compressor running in the state full loading, the eletricitity cost per hour is about 200 yuan, operating 800 hours per year, the electricity cost is about 1.6 million;
2. Compared with the single-stage compressor,two-stage compression compressor can reduce more than 10% of eletricity consumption. Two-stage compression will save 16 million per year.
