Turbine refers to a hydroelectric transmission device that converts the thermal effect of water flow into rotational mechanical kinetic energy. The key is used in hydropower plants to drive wind turbines to generate electromagnetic energy, which is an important electromechanical equipment for hydropower plants. According to its principle, it can be divided into two types: impact turbine and impact turbine. Let’s take a look at what is a hydro turbine? What is the structure of a hydro turbine?
What is a water turbine?
The water turbine is evolved from the water wheel or smuggling car in ancient times. In 1827, French technical engineer B. Fourneron made a 6-horsepower impact turbine. In 1849, it was improved by the design scheme of American technical engineer J.B. Francis to produce a contemporary Francis turbine, so it is called Francis turbine. The impact turbine occurred in 1850. By 1880, the American technical engineer L.A. Pelton obtained the patent right of the bucket-type impingement turbine, which is called the Pelton turbine. With the progress of the development and design of hydropower projects, the types, characteristics and structures of hydraulic turbines are becoming more and more perfect. In 1912, Austrian technical engineer V. Kaplan designed the first rotary propeller axial fan turbine, so it was called Kaplan turbine. In the 1940s and 1950s, axial-flow and oblique-flow turbines appeared one after another. At the same time, the development trend of hydraulic turbines was centrifugal pump turbines, which were used in pumped-storage power plants. The types of turbines can be integrated into the different goals and regulations of different water heads in the development and design of hydropower projects. After the founding of the People’s Republic of China, the industrial production of China’s turbine production and manufacturing was quickly completed. There are more than 20 turbine production plants, which have produced more than 20 million kW of turbine weapons and equipment for hydropower plants all over the country, and exported to overseas.
According to the characteristics of heat transfer, hydro turbines are divided into two categories, namely counterattack type and impact type. And each type of turbine is divided into various forms according to the characteristics of the water flow in the rotating shaft area and the structure type of the rotating shaft.
What is the structure of the turbine?
The hydraulic turbine is the hydraulic turbine of the hydraulic power generation mechanical equipment. The hydraulic turbine and the wind turbine, the speed regulating motor, the excitation regulator system and the power station control system are used in the supporting facilities, which constitute the main body of the hydropower station.
The water turbine is developed and produced according to the data flow and head size of water. Its function is to convert water into mechanical energy and promote the power generation of wind turbines. The turbine itself consists of the turbine shaft, the turbine seat ring, the turbine volute and the turbine main shaft bearing. In addition, depending on the specifications, additional equipment and components are also installed. Different types of turbines have different structures and applications.
