Characteristics of Francis turbine
With compact structure and high efficiency, Francis turbine can adapt to a wide range of water head
Type of turbine.
When water flows through the working wheel of this kind of turbine, it enters in the radial direction and leaves in the axial direction, so it is also called the radial axial flow turbine.
Francis turbine is also known as Francis turbine. Water flows into the runner from all directions, and then flows out from the runner in an almost axial direction. The runner is composed of upper crown, lower ring and blade.
It is suitable for the range of water head from 20 meters to 700 meters, simple mechanism, stable operation, and high efficiency, but it is generally used in the range of water head (50 meters to 400 meters). Unit output from dozens of kilowatts to hundreds of thousands of kilowatts. The turbine has a maximum output of more than 700,000 kilowatts. Is one of the most widely used type of turbine.

Q4,Is your company a trading company or a manufacturer?
We are a manufacturer of hydro turbine generators and started to promote the international market in 2013. Our factory is located in Sichuan, where China's water conservancy and hydropower is most developed. Welcome to visit our factory in China.
Q5, What is an acceptable MOQ?
For this product, our acceptable MOQ is 1 set.
Q6,How long is the delivery time?
Delivery times range from 15 days to 6 months depending on the model you are purchasing.
Q7,Does the runner of Francis turbine produce negative pressure during operation? If the negative pressure will be generated, where will the negative pressure be generated, and how much range should we choose the measuring instrument?
When the turbine is in an operating state of no-load, low head, small load, high head, and overload and large flow, it will cause the dynamic load caused by pressure pulsation and hydraulic disturbance.
Since the Francis turbine is a fixed-blade hydraulic machine, when the turbine runs away from the optimal working condition, a large vacuum is generated in the area near the axis of the draft tube due to the rotating circumferential velocity of the runner outlet water flow.
The pulsation produces instantaneous negative pressure, the vacuum is not high, and it is not suitable for measurement due to its generation in the casing. Vibration, audio and other alternative measuring methods can be considered.
Due to the uneven gap between the rotating part and the fixed part of the turbine, the center of the wheel is deviated from the center of the unit. The gap between the fixed and rotating labyrinth rings of the wheel is constantly changing with the rotation of the wheel, and the water pressure in the gap changes accordingly.
When the flow of water flowing into the runner loses its axisymmetricity, an unbalanced lateral force occurs and pressure pulsations also occur.
Q8,Does your company have its own independent official website?
Of course, and we can see more information about our company and products on our official website.
