Tailing slurry pressurizing centrifugal water pump

A tailing slurry pressurizing centrifugal water pump comprises a pump body, a partition plate is arranged in a diffusion pipe of the pump body, and the diffusion pipe is divided into a high-speed flowchannel and a low-speed flow channel through the partition plate; from the water inlet end to the water outlet end, the acceleration of the sectional area of the high-speed runner is greater than that of the low-speed runner; a pressure stabilizing tube is arranged at the tail end of the diffusion tube; the cross section of the partition plate is streamline in the water flow direction. The pressure stabilizing pipe is tangent to the diffusion pipe, and vortex generated by pressure sudden change of confluence water flow can be eliminated. And the pressure stabilizing pipe can enable the converged water flow to form stable laminar flow, so that hydraulic loss caused by eddy current is reduced. In addition, the structure of the partition plate is optimized, vortex generated by the partitionplate is reduced or elimin
