Son rotates in its respective compression chamber respectively, carries out two second compressions to air；
The primary rotor is connected to the compression chamber of secondary rotor by an intermediate oil-gas pipeline, so that the air passes through
Into progress second-compressed in the compression chamber of secondary rotor after the compression chamber of primary rotor；
Arrangement, the air inlet are located at up and down along vertical direction in shell for the one stage of compression chamber, two-stage compression chamber
The top of one stage of compression chamber.
In a preferred embodiment: the integrated oil path system is provided in the intermediate oil-gas pipeline, to middle oil
Spray cooling oil in feed channel reduces the gas temperature in intermediate oil-gas pipeline, so that the gas temperature in two stages of compression is substantially
