Two Stage Compressor

Two-stage compression technology advantages:
  • Two-stage compression to improve compressor energy efficiency
  • Its energy efficiency is based on improvement
The following two main reasons:
First, each level lower pressure ratio, improve the volumetric efficiency, reducing each level of the internal and external leakage; the second is in the oil and gas mixture into a two-stage exhaust. The oiland gas mixture into the second stage of the compressor pressure Shrink, also makes the second stage. The compression process is closer to the isothermal process and improves the energy efficiency of the compressor. The first stage compression rotor and the second stage compression rotor are combined in a single casing and connected separately. Direct drive through the helical gear, so that each rotor can get the best linear speed, compressor transmission efficiency is highest.
Second, The compression ratio of each stage of compression is precisely designed to reduce the bearing and gear load. Compression ratio of each stage is small, smaller leakage, high volumetric efficiency.
Third, Two-stage compression reduces the compression ratio at each stage. It can reduce internal leakage, increase volumetric efficiency, reduced bearing load, improve the life of the host.

Two-stage compression process:
Natural air enters the first stage of compression through the air filter, with less compression chamber.
The amount of oil mixture, while the compressed gas mixture to the interstage pressure.
The gas enters the cooling channels and comes into contact with a large amount of oil mist, which drastically reduces the temperature.  
After cooling the compressed gas into the second stage rotor, the second compression is compressed. 
To the final exhaust pressure. Finally discharged through the exhaust flange compressor to complete the entire Compression process.
