Embodiment 2
[0030] Figure 9 It is a schematic cross-sectional structure diagram of the hydrodynamic energy-saving water pump provided in the second embodiment of the present invention. The fluid power energy-saving water pump can include a reverse water valve 1, a pump body 2, an air tank 3 and an impact valve 4, wherein the pump body 2 includes a water inlet, a reverse water opening and a water outlet, and the water outlet is fixedly provided with an impact valve 4. The tank 3 and the pump body 2 communicate with each other through the reverse water valve 1 at the reverse water port. like Figure 9 In the sectional view of the energy-saving water pump shown, the left side of the pump body 2 is the water inlet, the right side is the drain outlet, and the top is the reverse water outlet. The pump body 2 also includes a pump body back cover 21 . At the water outlet, the pump body back cover 21 is fixedly connected with the pump body 2 through bolts, and the impact valve 4 is fixed inside...
