Water power drives pumps and generators水能驱动水泵和发电机

Water drives water pumps and generators, and a hydroelectric generator is a device that uses the energy of water flow to convert it into electricity. Its principle is to use the kinetic energy and gravitational potential energy of the water flow, convert the energy of the water flow into mechanical energy through the water turbine, and then convert the mechanical energy into electrical energy through the generator. The core components of a hydroelectric generator are a water turbine and a generator. A water turbine is a device that converts the kinetic energy of water flow into mechanical energy. Its working principle is similar to the wind wheel of a wind turbine. A water turbine usually consists of components such as an impeller, a shaft, and a bracket. When the water flows through the impeller, the impeller will turn, which will drive the rotation of the shaft. The speed and direction of rotation of the shaft depend on the velocity and direction of the water flow. The rotational energy of the turbine is
