Document Type and Number:
Japanese Patent JP2015113714
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a rotary machine assembly and a centrifugal rotary machine capable of improving operation efficiency while restricting the right upper characteristic generation throughout the system.SOLUTION: A rotary machine assembly comprises: a revolving shaft 3; impeller blades 4 in multiple stages fixed to the revolving shaft 3; connection channels 20 for causing a fluid W that drains toward the outside in a radial direction from the impeller blade 4 in a front stage to enter the impeller blade 4 in the subsequent stage from the outside in a radial direction; and a diffuser vane 25 provided in each connection channel 20, in which when the ratio of the diameter dimension D2 in the exit of the impeller blade 4 to the diameter dimension D3 in the entrance of the diffuser vane 25 is defined as the diameter ratio D3/D2, diameter ratios D3/D2 are different from each other in at least two connection channels 20 in a plurality of connection channels 20.
