Document Type and Number:
WIPO Patent Application WO/2016/127731
Kind Code:
A1
Abstract:
Disclosed is an inter-pressure impeller mechanism, comprising impellers (1), wherein at least two impellers (1) are correspondingly disposed, and a boost flow path (3) is arranged between two adjacent impellers (1); and with the arrangement of the boost flow path (3), the inter-pressure impeller mechanism can reduce the stage number of traditional impeller mechanisms, and can weaken shock waves in the use of a contra-rotating structure, and has the advantages of a simple structure and a high efficiency.
