Description

Francis Turbine Generator Unit
Product Introduction
Francis turbine is also called Francis turbine,is a kind of counter turbine ,by the American engineer Francis invented in 1849, also known as Francis turbine ,or radial axial flow turbine The structure of the Francis turbine is simple ,the main components include volute ,seat ring , water guide mechanism .cover ,runner ,spindle .guide bearing ,bottom ring ,tail pipe ,etc .Volute is a water diversion parts ,shaped like a snail shell ,generally made of metal materials .circular section .The seat ring is arranged between the volute and the guide vane .which is composed of the upper ring ,the lower ring and a number of columns and is directly connected with the volute .The column is a wing shaped ,non rotating . aiso known as guide vane The water guide mechanism is movable quide vane ,speed reguiating ring ..connecting rod and other parts The directly connected with the spindle ,Francis turbine is also called Francis turbine ,is a kind which is the o this type of .The runner is composed of the upper crown .lower ring .drain cone and a number of fixed blades .The shape and matching size of each component are different according to the water head used .The tail pipe is the water flow from the runner to the downstream of the turbine discharge parts ,generally elbow shape, small turbine straight conical tail pipe ,water flow from the surrounding radial flow into the runner ,and then approximate axial flow out of the runner .The development trend in recent years is high head ,large capacity .high specific speed and high efficiency .The mingda factory produces Francis turbine generator sets which is the rotating part of this type of turbine .The are mainly with horizontal shaft and vertical shaft .
The features of rare earth permanent magnet motor
1.The features of Francis turbine is simple structure and reliable operation :high efficiency ,suitable for water head of 10m-70m ,which is currently one of the mostly widely used :
2. When the water flows through this kind of turbine working wheel ,it enters and leaves in the radial direction ,so it is also called the radial axial flow turbine :
3. Mixed hydro turbine ,also known as Francis turbine . water flow from the surrounding radial flow into the runner ,and then approximately axial flow out of the runner ,the runner is composed of the upper crown . lower ring and blade :
4. Itis suitable for the 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 m to 400 m ) .output from kilowatts to hundreds of thousands of kilowatts .At present ,the maximum output of this of turbine has exceeded 700.000 kilowatts .It is one of the most widely used water turbine
.

Range of Application
The main components of the inclined-jet turbine are similar to the pelton turbine, the two kinds water turbine also have nozzle and working wheel. The difference are as follows:
1. The placement position of the nozzle is not in the same plane with the working wheel, but in an angle with the plane, which is called oblique angle.
2. The wheel of pelton turbine is spoon-shaped, with axial force, the jet inters from one side of the wheel and flows out from the other side.
3. The outer circle of the pelton wheel has an outer wheel ring, which increases the blade strength and reduces part of the wind resistance loss. The inclined-jet turbine occupies a unique application range(in the specific speed of n-30-70 range ). and the francis turbine is
not applicable, a single nozzle pelton turbine can not reach this specific speed. And the efficiency of cross flow turbine is too low.
