| Abstract: | On the bases of many designs and tests , provides the hydraulic design way on computer aideddesign of double-channel impeller, and with some main parameters. Gives the values of inlet speed coefficientKD1 and outlet speed coefficient KD2 , and introduces the ways of calculating radius R1 of front cover board andradius R2 of back cover board. A midline equation of impeller plan channel and a change rule of channelsection area are suggested in this paper for the first time. |
