i.) General Description of the Francis Turbine
A Turgo turbine consists of three major parts, the nozzle system, the runner and the bracket. the flow enter the water inelt nozzle from penstock, through MIV, expansion joint, inlet tube. by the open and close of the needle valve in the nozzle, thus control the flow into the turbine. The water enters the runner evenly and impacts the runner to convert the water energy into mechanical energy, and transmit through the main shaft to drive the generator rotor to rotate and then the generator converts the mechanical energy into electric energy.
1). Water inlet structure: consists of inlet valve, expansion joint, etc. the inlet valve is to cut off the water in case of shut down the unit. it can also be used to emergently close the water in case of the unit accident and failure of the water distribution mechanism. The expansion joint is used to compensate the installation tolerance, and facilitate the install and dismantle of the MIV, it connect the nozzle at one end, to convey the water into the bracket.
2). bracket: the turbine bracket is weld structure with steel board and stay rings. It holds the nozzle system, the runner and shaft together and support the generator on top.
The water leave the runner also discharges from the bottom of the turbine bracket.
3). Runner: the runner the heart of the turbine, it converts the water energy into mechanical energy. The runner consists of upper crown, lower band, runner blades, combined by means of welding.
