For the main problems in practical applications of the impeller (key part of the large-scale centrifugal compressor), based on the product integrated design theory, the design quality model of the impeller overall considered its structural performance and manufacturing performance is built, and the viewable optimization design method is used to complete the structure innovation of the new impeller. Accordingly to the design method above, reference is provided for the innovative design of the other key components of machinery products.
