Hydroelectric power gear box, designed for low head and large flow shaft extension, shaft, bulb tubular units and vertical axial-flow units, units for Cline. With increase (decrease ) the speed of double effect, such as for water pumps on to slow down in Tubular unit, when the turbine rated speed less than 214.3r / min (50Hz) and unit capacity Np = 600 ~ 6000kW, recommend the use of planetary gear growth program. enhanced by growth allows the generator speed to 500 600 700 or 1000r / min. through hydroelectric turbine gear box so increase the generator speed ( greatly reduced number of motor poles ), which bring great economic benefits of water conservancy investment .
Power permissible range :
200 ~ 30000kW
Speed : without any restrictions
Ratio : 2 to 25
Maximum output torque : 3000kNm
