3-D entity modeling of double-channel impeller based on Pro/Engineer

QI Xue-yi,YAN Xiao-wei,ZHANG Qing(College of Fluid Power and Control,Lanzhou Univ.of Tech., Lanzhou 730050,China)  
Aimed at the deficiency in conventional designing method of impellers of sewage pump with double channels,a 3-D entity modeling method for this type of pump impellers was developed with the Pro/Engineer software.In this method,the Archimedes spiral was adopted as channel midline which could be generated by programmer in the process of modeling,and the original wooden patterns and the area change rule of channel could be modified,so that 3-D design of double-channel impellers could be implemented.Having more systematically given design procedures and process,and comparing the result of the numerical simulation with the given method to that of pump test with clean water,it was shown that the structure was reasonable,but needed to verify further experimentally its effect of the multiphase medium transportation.
