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 :

1. 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
2. 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.
3. 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.
4. 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.



Features description:

1. Oil injected screw air compressor can achieve the usual power system exhaust pressure by only Single stage compression. But from the view of energy consumption point, the use of 2 stage of compression can effectively reduce energy consumption.
2. So, Tianjin Great air compressor co., LTD. has introduced 2 stage compression of energy efficiency screw air compressor. The 2 stage compressed-jet screw air compressor has more capacity of 12% to 18% than the single stage compressed injection screw  air compressor with the equivalent power. In other words, with the same amount of compressed air, the 2 stage compression can save an average of 15% of power compared with 1 stage compression
3. 2 stage compression of oil injected screw machine has the unique design of the air end, it will combined the1 stage compression rotor and 2 stage compression rotor within a chassis, make each rotor can get optimal linear velocity by the gear directly rotating respectively, so the compression efficiency is higher. 

2 stage compression air compressor, take the built-in spray curtain of cooling, cooling effect is good, greatly reduces the temperature of compressed air, realize the nearly isothermal compression, and can reduce the pressure loss of between 1 class ~ 2 class, lower compression ratio and improve the compression efficiency


 

1. After 1 stage compression, coolant through multiple jet hole on the body, form the mist jet shade, to cool the hot 1 stage compressed air, greatly reduces the compressed air temperature before entering the 2 stage compression, which is near to isothermal compression process, save the energy compression effect.
2. Even without inter-stage cooling, two stage compression is more efficient than single stage compression. This is because the volume of air becomes smaller after the 1 stage compression, so the 2^nd stage compression can use a smaller diameter of the rotor, and the leakage rate of the unit volume is small.
3. Reduce internal leakage: use 2 stage compression, reduce the compression ratio of each compression, reduce the leakage from the high pressure side to the low pressure side per class, and improve the volume efficiency.
4. Noise reduction: the compression ratio of each compression is reduced by taking 2 stage compression, which greatly reduces the noise, especially the unloading noise
5. 2 stage compression unit, except for screw air end, the other system and structure arrangement of the unit is basically the same as the single stage compression, which is convenient for the maintenance and usage to the user.
6. For users  who need  large air consumption and continuously use, should take priority to use of a 2 stage compressed  1 class energy efficiency air compressor

TKL- Series of 1 class energy efficiency air compressor with 2 class,3 class energy efficiency comparation:

According to the national GB19153-2009 energy efficiency rating	1 class(1 class<=5.5; 2 class<=6.2;3 class<=7.1)	2 class(1 class<=5.5; 2 class<=6.2;3 class<=7.1)	3 class(1 class<=5.5; 2 class<=6.2;3 class<=7.1)

1. Compared with the 2 class energy efficiency air compressor unit, the electricity saving cost is: Energy saving per hour(6.12-5.45)*41.4=27.738KWH  saving for 8000 hours $27.738*8000*$0.12=$26629
2. Compared with the 3 class energy efficiency air compressor unit, the electricity saving cost is: Energy savings per hour (7.037-5.45)*4.14=65.7018KWH saving for 8000 hours $65.7018 *8000*$0.12=$63074
