High-lift water pumping device

The utility model relates to the technical field of water pumping devices, in particular to a high-lift water pumping device which comprises a pump and is characterized in that the pump comprises a water pumping pipe and a water pumping pipe, the water pumping pipe is communicated with a circulation structure, and the circulation structure is used for receiving part of pumped liquid and conveying the liquid back to the pump to fill the water pumping pipe. Part of liquid is received and stored through the circulation structure, the liquid in the circulation structure is automatically conveyed back to the pump before the pump is started next time, and after the liquid flows to the edge from the center of the impeller, low pressure is formed in the center of the impeller, and the liquid is sucked in. When the installation position of the high-lift water pumping device is high, if air exists in the water pumping pipe, the air in the water pumping pipe expands when the pump works, liquid is difficult to suck in, t
