This utility model relates to the field of water pump impeller technology and discloses a high-efficiency water pump impeller structure based on CFD analysis. It aims to solve the problems of large hydraulic losses and low efficiency in traditional impellers. Its core structure includes a coupling, on which a water pump impeller mechanism and an auxiliary flow guiding mechanism are integrated to form a coordinated water delivery system. The coupling has a water pump impeller mechanism and an auxiliary flow guiding mechanism on its surface. In the water pump impeller mechanism, the inner sleeve is fixed to the coupling, and the outer sleeve is connected to the inner sleeve's insertion slot via a plug-in block. The first and second water pump impeller blades outside the outer sleeve are staggered and alternately distributed, with tail flow holes at the outer ends of the blades. A limiting hole and a limiting top cover are provided at the top of the coupling. The base plate of the auxiliary flow guiding mechanism is mounted on the coupling. The flow guiding shell and the flow guiding cover are connected by a mounting base and bolts. The flow guiding shell has drainage holes. This structure, optimized by CFD, can reduce water flow interference and eddy current losses, improve water delivery efficiency, and is easy to disassemble and maintain, adapting to different working conditions.
