Long-distance large-pipe-diameter pipe water-conveying three-stage pressure station water-lifting system

The invention discloses a long-distance large-pipe-diameter pipe water-conveying three-stage pressure station water-lifting system which comprises a water source point, a primary pump station, a secondary pump station, a third-stage pump station and a third-stage pump station outlet pool. The water source point is connected with a primary pump station inlet pool, the primary pump station is connected with a secondary pump station inlet pool through a water conveying pipe, the secondary pump station is connected with a third-stage pump station inlet pool of the third-stage pump station through a water conveying pipe, and the third-stage pump station is connected with the third-stage pump station outlet pool through a water conveying pipe. Pressurized water lifting is performed by arranging a structure of the three-stage pressurized pump stations, each stage of pump station works stably, so that low-altitude excellent spring is lifted to the high altitude, and then water resources are rationally distributed. Therefore, the regional water supply requirements are met, the regional social and economic development is accelerated, the water resource allocation is optimized, water is utilized scientifically and rationally, and the building of the water saving society is promoted.
