The drop of water forms kinetic energy under the action of gravity. Water is diverted from high-level water sources such as rivers or reservoirs to low-level locations. The pressure or flow of water is used to. impact the turbine and rotate it, thereby converting the energy of the water into mechanical energy. Then the water turbine drives the generator to rotate, cutting the magnetic lines to generate alternating current.
Low-level water is distributed throughout the earth through the absorption of sunlight by the water cycle, thereby restoring water distribution from the water source of high level.
Water can not only be directly used by humans, it is also an energy carrier. Solar energy powers the Earth's water cycle and keeps it running. Surface water flow plays an important role. In areas with high falls and significant flows, theWater energy resources are abundant. As fossil fuels become increasingly scarce, hydropower represents a very important and promising alternative resource. Hydroelectric power generation around the world is still in its infancy. Water movements such as rivers, tides, waves and waves can all be used to generate electricity. Some of the water can also be used for irrigation.
Basic principle: In a hydraulic turbine, water flows radially into the water guiding mechanism due to the guiding effect of the volute, converting the kinetic energy of the liquid into static pressure energy. , then converts the static pressure energy through the blades. The pressure energy is converted into the kinetic energy of the rotor.
The runner is coupled to the generator rotor via the main shaft, driving the rotor to rotategold and cutting the magnetic coil of the generator stator. It uses the principle of electromagnetic induction to generate high voltage electricity in the generator coil. , then increases the voltage across the transformer for transmission. The cabling exports energy to the network and water flows axially out of the channel.
Large and medium-sized hydraulic turbines generally use metal scrolls, the main function of which is to guide the flow of fluid and convert the kinetic energy of the liquid into static pressure energy. The tilt angle of the movable guide vanes in the water guiding mechanism is adjustable, and its main function is to adjust the flow rate.
Hydraulic generator refers to a generator that uses a hydraulic turbine as the prime mover to convert water energy into electrical energy. When water flows through the turbine, the energy of the water isconverted into mechanical energy. The rotating shaft of the turbine drives the generator rotor, which converts mechanical energy into electrical energy and produces it. It is the main electrical equipment for producing electrical energy in hydroelectric power stations.
