The hydraulic turbine is a power machine that converts the energy of water flow into rotating mechanical energy The Francis turbine can operate at a water head height of 20-700 meters The output power ranges from several kilowatts to 800 MW It has the widest application range stable operation and high efficiency
The hydraulic turbine is a power machine that converts the energy of water flow into rotating mechanical energy The Francis turbine can operate at a water head height of 30-700 meters The output power ranges from several kilowatts to 800 MW It has the widest application range stable operation and high efficiency
The axial-flow turbine is suitable for medium and low water heads which is appropriate for the water heads of 3m to 65m the characteristic is that when the water flows through the runner it always follows the direction of the axis
In order to prevent the accident from expanding overhauling or shutting down for a long time a main inlet valve must be installed in front of the turbine It is generally necessary to install a valve in front of the turbine when a steel pipe is branched to supply water and several units or the pressure diversion pipe is very long
The governor adjusts the opening of the guide vane based on the deviation of the unit speed to achieve the purpose of changing the output and keeping the speed stable The task of the governor system is continuously adjust the output power of the hydro-turbine generator unit to maintain the unit's speed frequency within the specified range of the rated speed frequency The governor is applicable for the single and double regulating systems of all types of the 1MW-100MW water turbines including Francis type axial flow type cross-flow type and impulse type etc
