Product features :
Francis turbine is a kind of counter-attack turbine, invented by American engineer Francis in 1849, also known as Francis turbine, or radial flow turbine. Water flows radially into the runner, and then flows out approximately axially. The runner consists of a crown, a ring and a blade.
Francis turbine has wide application head (about 20-700m), simple structure, stable operation and high efficiency, and is the most widely used type of turbine in modern times.

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.
