Method for designing centrifugal pump and mixed flow pump having specific speed of 150-1200

摘要

A method for designing a centrifugal pump and a mixed flow pump having a specific speed of 150-1200 comprises a design specification determination step for a turbo pump including an impeller, a specific speed determination step for the impeller, a design variable determination step for the impeller, and a three dimensional shape deriving step for the impeller. According to the present invention, the three dimensional shape of the impeller can be simply designed by converting the design variables related to the specific speed into a function and by putting optimized design variables into a database.
