Feature for 2 stage compression screw air compressor :
The state clearly classifies energy efficiency levels limit value. The 2 class energy efficiency products can save 10%~15% of the power than 3 class energy efficiency products.and the 1 class energy efficiency products can save 10%~15% of the power than 2 class energy efficiency products. energy-saving effect is remarkable .
Energy -saving principle :
- Curve 12 '3' is an isothermal compression process, it form the area of 613 '4 with Y-axis which is the indicated work of isothermal compression
- Curve 123'' is the 1 stage compression process, it form the area 613 ''4 with Y-axis which is the indicator work of the 1 stage compression.
- Curve 12, 22 'and 2' 3 are the 2 stage compression process, and the sum of the area 6125 and the area 52 '34 (6122' 34) with Y-axis which is the indicator work of the 2 stage compression.
- It can be seen from the diagram that the isothermal compression process 613 '4 area (indicating work) is the smallest, but it is impossible to achieve isothermal compression in the air compressors' actual compression.
The 1 stage compression has the bigger area of power 13 '3 than isothermal compression, while the 2 stage compression saves 22" 33 "area of power.
