Introduction of hydro turbine
Hydropower turbine is designed and manufactured according to discharge and head, its role is to turn water into mechanical work, and drive the turbine generators to produce electricity.
Hydro turbine consist of runner, seat ring, spiral casing and main shaft. Beside, it’s equipped with auxiliary devices and components depending on the different type.

The turbine is divided into two categories: reaction turbine and impulse turbine.
Reaction turbine use the pressure energy and kinetic energy of water flow, is divided into francis type, kaplan type, diagonal type and tubular type (bulb turbines, pit turbines, etc.) according to the water flow movement direction inside the runner area.
Its components and parts: flume(spiral casing), water distributor, runner, draft tube, shaft and bearing etc.
Impulse turbine use the kinetic energy of water flow, is divided into pelton type, inclined-jet type and cross-flow type according to the jet impact the scoop in different ways. The inclined-jet type and cross-flow type type turbine only applies to small turbine. Its components and parts: spray pipe, baffle plate, runner, housing casing, shaft and bearing etc.

Hydro power - How it works
Internationally, about 20% of all electricity is generated by hydropower - the world's most widely used source of renewable energy. In Nepal, 100% of electricity is generated from hydro sources. In countries such as Peru, Brazil and Norway, more than 85% of their electricity uses hydropower. In New Zealand, about 60% of electricity is generated from hydro sources. In China till 2009, about 22% of electricity is generated from hydro sources.

Hydroelectric power stations capture the energy of falling water to generate electricity. Two factors are used to assess the generating capacity of a waterway. The first is the quantity of running water, or ‘flow rate', measured in cubic metres per second. The second is the difference in vertical metres between the intake pipe and the turbine outlet, or ‘head'.

Hydropower works by converting the movement of falling water into electricity. Many forms of hydro power exist and have been used by humans throughout history, some examples of this are watermills powering machinery such as sawmills and farmers irrigating land using gravity.

Most often water is stored in dams or reservoirs. This water flows through an intake and into a large pipe called a penstock. The penstock then feeds water into a turbine which powers a generator.

The turbine is powered by water flowing through the wicket gate. This gate can be controlled to determine the rate of flow through the turbine and therefore the amount of power generated. The turbine is attached by a shaft to an electric generator.
