No, the water pump has a motor, not a generator. The electric motor can only be connected to the power source and then rotate, while the generator uses external force to rotate it to generate current.
In addition, the water pump impeller and turbine impeller are also different, and other supporting equipment is also different.
But there is a kind of hydroelectric power plant called a pumped storage power plant. It has two tanks, an upper tank and a lower tank. During the day, water is released from the upper reservoir to generate electricity. At night, excess electricity from the nighttime power grid is used to pump water from the lower reservoir to the upper reservoir. It will continue to produce electricity the next day, mainly to regulate peak load.
Why is the motor not circulatinguse water to produce electricity?
The average efficiency of small and medium-sized hydropower generation units is 75% to 85%, and the average efficiency of large units is above 90%.
Hydroelectric power generation efficiency is calculated at 80%
Engine efficiency is calculated at 80%
Losses along pump and pipeline, efficiency is calculated at 85%
p>
Total efficiency = 80%*80%*85%=54.4%
Loss of 45.6% electricity
To tell you simply, the water in your engine So that it can circulate because there is a water pump. The water pump is powered by a belt driven by the engine crankshaft. The power from the engine goes to the water pump, then the water gives energy to the generator, which is transferred twice depending on the energy transfer. . . If an external generator is used, the power from the engine is sent to the generator through a belt and the energy is ttransferred only once.
