【Abstract】 An analysis is made on the operating efficiency of centrifugal pumps and the unit consumption of water supply in theory. Then, beginning with the changing law with the operating efficiency of centrifugal pumps and the unit consumption index of water supply, the water supply facilities are improved in technology with attentions paid not only on making the water pump work in a “high-efficient section”, but also on making it work in low unit consuming section in the process of designing and management. According to the practical conditions, the lift of the water pump should be adjusted in order to reduce the cost as much as possible and increase economic efficiency.更多还原
