All equipment shall be carefully packed so as to withstand the long time transport by sea and land. The electrical equipment shall be completely protected against moisture.
The finished surface of the equipment and the portion embedded in concrete shall be protected by rust preventive means.
The spare parts shall be packed and crated firmly enough to withstand storage for a long time, and those in need of rust preventive treatment shall be so treated.
Francis turbines of both vertical and horizontal types are suitable for water head from 10m to 300m.
This hydraulic turbine type is Horizontal Francis. A inlet valve is equipped in front of the spiral casing of the turbine. When viewed at the turbine from the generator end, the rotating direction of the hydraulic turbine is clockwise .The turbine runner type are HLA616. it's runner diameter are 65cm, horizontal shaft and metallic spiral casing. This unit has two bearings, assembled on the generator seat. The principal parts of the structure of turbine as follows:
Spiral case assembly
Rotating parts assembly
Inlet tube assembly
Draft tube assembly
Layout for water,instruments and pipe-line
Water flows through penstock of the power station, Sluice valve, expansion pipe. inlet tube. spiral case and wicket gates into the runner, then it drives the runner to revolve and convert hydraulic energy into mechanical energy and drives the rotor of generator revolution by the force of the main shaft of turbine, thus converting the mechanical energy into electric energy.
