PROBLEM TO BE SOLVED: To generate electric power by reversely rotating a pump by causing inflow water to flow into an impeller of the pump during stopping such as a water reservoir.SOLUTION: Inflow water 1 passes through an inflow pipe 2, arrives at an inflow pumping switching machine 3, pushes up a check valve in the inflow pumping switching machine by water pressure, passes through the inflow pumping switching machine, enters a hybrid pump 5, hits against an impeller in the hybrid pump 5, rotates the impeller, and rotates a rotor of the hybrid pump 5. Because the rotor is made of a permanent magnet, electric power is generated by the rotation. |
