Impact type hydraulic turbine

Is suitable in 100 800 meters hydroelectric power stations. This hydraulic turbine other name sink type or cuts strikes the type, belongs to the high flood peak, the small current capacity type. Its characteristic is uses the fluent kinetic energy acting the machine, becomes from the pressure steel pipe's high-pressured current of water through the nozzle nose's spray nozzle has the high speed open jet, the jet flow water body pressure is the atmospheric pressure, does not change in the entire work process. When jet flow impact hydraulic turbine runner, from entry to the departure runner's process, its speed's size and the direction has had the change, the export speed of flow and the kinetic energy to reduce greatly, the jet flow has paid its kinetic energy the runner, causes runner revolving. Its installment way has the vertical shaft and lies the axis two kinds, the former arrangement is quite compact, saves the construction to invest, but the workshop is highly big, the latter workshop is highly small, but the area is big. Generally the large and middle scale impact hydraulic turbine often uses the vertical spindle type, but the small impact type hydraulic turbine uses lies the shaft type.
