Key points of two-stage screw air compressor exceeding the first level of energy efficiency:
Compared with single-stage compression, two-stage compression tends to be the most energy-efficient isothermal compression. In principle, two-stage compression is more energy-saving and power saving than single-stage compression.
The use of two-stage compression host means that two groups of screw rotors with different sizes are used to achieve reasonable pressure distribution and reduce the compression ratio of each compression. The low compression ratio has two special advantages. One is to reduce internal leakage and improve volumetric efficiency. The other is to greatly reduce the bearing load, improve the bearing life and extend the service life of the main engine.
