たことを特徴とする多段ターボ圧縮機の流量調整装置。An inlet guide vane at the inlet of the second stage impeller and an outlet guide vane at the outlet of each stage impeller can be rotated an appropriate number of times at an appropriate pitch along a circle concentric with the first rotation axis common to each stage impeller. In the flow rate adjustment device for a multi-stage turbo compressor, the second rotation axis of the outlet guide vane is common to each stage, and the third rotation axis of the first inlet guide vane and the second rotation axis are rotated as appropriate. The blades are formed to be rotatable in conjunction with each other at a constant rotation ratio by a transmission means, and the ratio of the length of each stage exit guide vane on the side opposite to the impeller with respect to the second rotation axis as a boundary is determined. Based on the swirling angle of the gas in each stage during partial load operation, the outlet guide vane on the rear stage side is made larger so that the change in the tangential angle of the tip of the outlet guide vane on the impeller side with respect to the rotation of the second rotating shaft is controlled. A flow rate adjustment device for a multi-stage turbo compressor, characterized in that each stage outlet guide vane is attached to a second rotating shaft so as to be thick.
