Abstract According to the feature that the axle power curve of the low-specific-speed sewage pumpincreases with its flow rate,deduces in theory the conditions for the sewage pump to have an non-overloadpower characteristics,and analyzes the effect of basic geometric parameters on the head-flow curve, andprovides with the range and the principle of selecting the basic geometric parameters in non-overload sewagepump hydraulic design,and gives a design example which is a helpful inferences in the design of non-overloadsewage pump.
