Sell Francis Turbine Generator Units

Francis turbines of both vertical and horizontal types are suitable for water head from 10m to 300m. lts feature is that the water flow enters the runner inward in a radial direction , changes direction gradually and then passes out axially. Francis turbine is characterized by reliable operation, simple construction and high efficiency, etc. Normally, we adopt the horizontal Francis with capacity below 5MW, runner diameter below 90cm.


Sell Kaplan Turbine Generator Units

The Kaplan (axial-flow) turbine for low head from 2m to 70m. lts feature is that the water flow passes through the runner axially. The axial-flow turbine can be classified into two forms according to the runner construction: one is fixed blades (Propeller) for small variation of head and power, the other is movable blades (Kaplan) for large variation of head and power.


Sell Tubular and Bulb Turbine Generator Units

Tubular turbine and Bulb turbine is suitable for heads from 2m to 20m and large discharge. lts feature is that the water flow is axial throughout the passage from the inlet to the outlet, so that the passage is a straight conduit essentially. The tubular turbine is characterized by good characteristic of water flow and high efficiency etc.


Sell Pelton Turbine Generator Units

The Pelton hydraulic turbine is suitable for heads fron 80-1600m. lt utilizes the dynamic power of water flow to rotate the runner and do work, The centre line of the jet is in the same plane as the runner. Pelton turbine has the advantages of compact construction, stable running and easy operation.
