Abstract
Small and medium-sized axial-flow pumps are widely used in water conservancy drainage and low-lift irrigation projects.As a key part of the water inlet of the pump,the shape and suspended height of the bell mouth determine the initial conditions for the water to enter the pump,which in turn has a great impact on the hydraulic performance,operation stability and energy consumption of the pump.Through comprehensive analysis and comparison,this paper puts forward reasonable suggestions on the bell mouth shape and suspended height of small and medium-sized vertical axial flow pumps for engineering reference.关键词
