CENTRIFUGAL ROTARY MACHINE

摘要

Provided is a centrifugal rotary machine that comprises: a rotor (2) that has a rotary shaft (4) that rotates around an axis (P), and impellers (3) that rotate together with the rotary shaft (4); a casing (7) that surrounds the rotor (2) from an outer peripheral side; diaphragms (6) that are provided such that a plurality thereof are stacked in a direction of the axis (P) between the rotor (2) and the casing (7), and that define a flow channel for a fluid (G) that is pressure fed by the impellers (3); and restraining members (20) that restrain the diaphragms (6) from an outer peripheral side.
