| Abstract: | It is shown after analysis that the efficiency of roto-jet pump is higher than theefficiency of multistage pump and express pump when it operates in the region of low dis-charge and high lift. Based on the investigation of studying the compatibility of the pick-uptube and the impeller of the roto-jet pump as well as hydraulic loss of the expanding sectionof the pick-up tube,the design formulas of hydraulic parameter of the expanding tube is pre-sented. |
