Introduction of slanting turbine

The slanting turbine uses a nozzle to change the pressure energy of the water flow into velocity energy. The water flows from the exit nozzle to the runner until the entire working process of leaving the runner, not in a closed system, but in an atmosphere-filled enclosure. A free jet is formed, and at the same time there are often 3-4 buckets that receive such free jets of varying flow sizes from the same nozzle. The jet exit jet center has a certain angle with the runner inlet plane (usually 22.5 degrees).

The main working parts of the oscillating turbine are basically the same as the cutting turbine, except that the working jet is at an angle α to the inlet plane of the runner, and the jet is directed obliquely toward the runner. The slanting turbine is suitable for small and medium-sized hydropower stations with a water head of 35-350m, a shaft power of 10-500kW and a specific speed of 18-45.
