[0002] A water turbine is a power machine that converts the energy of water flow into rotational mechanical energy. It belongs to the turbine machinery among fluid machinery. Most modern water turbines are installed in hydropower stations to drive generators to generate electricity. In a hydropower station, water from an upstream reservoir is led to the water turbine through a water diversion pipe, which drives the turbine runner to rotate and drives the generator to generate electricity. The water that has done work is discharged downstream through the tailwater pipe. The higher the water head and the greater the flow rate, the greater the output power of the water turbine. In the production and processing of the water turbine casing, due to the volute shape of the water turbine casing, it is not easy to clamp and fix the casing.
