General screw air compressors can also achieve normal applications such as common power system exhaust working pressure only with unipolar compression. However, from the perspective of energy consumption and power application, the use of bipolar compression can effectively reduce energy consumption and bring higher application output power and gas consumption value. Therefore, in the screw air compressor, a more energy-saving two-stage compression air compressor is introduced.

Compared with unipolar compression, bipolar compression is close to the most energy-saving isothermal compression. From the basic principle, secondary compression saves 6~10% energy than unipolar compression. Bipolar compressors are used in two groups of different sizes. The screw motor rotor realizes reasonable working pressure distribution and reduces each compression ratio. A low compression ratio has two advantages: one is to reduce internal leakage and improve capacity efficiency; the other is to greatly reduce the load of rolling bearings , Improve the service life of rolling bearings, extend the service life.
