【Abstract】 Based on Prof. Wu’s three-dimensional flow theory, the design improvement of a pipe inline pump has been done for the first time. The test results are following: the efficiency of the pump increases from 68.5% to 72.9% at design capacity and the best efficiency of the redesign pump is about 75%. It is verified that three-dimensional flow theory has great potentiality to improre pump design.更多还原
