FIELD: machine building.
SUBSTANCE: proposed method isolating, at least, two fluid compression stages and, simultaneously, initiating multistage compressor rotation. Proposed system comprises compressor rotation driving mechanism and multiple flow circuits. Every said circuit communicates with appropriate one compression stage to allow communication of compression stage inlet and outlet. Besides system includes isolating valve arranged between two flow circuits. Said system allows changing from starting conditions to normal operating conditions. In starting conditions, said valve is closed to prevent fluid leaks between two flow circuits. In normal operating conditions, said valve is open to allow fluid flows between two circuits.
EFFECT: reaching normal operating conditions without extra drive.
