Product features:

The Francis turbine has a simple structure, and the main components include a volute, a seat ring, a water guiding mechanism, a top cover, a runner, a main shaft, a guide bearing (see a turbine guide bearing), a bottom ring, a draft tube, and the like. The volute is a water-conducting component, which is shaped like a snail shell and is generally made of a metal material with a circular cross section. The seat ring is placed between the volute and the guide vane, and is composed of an upper ring, a lower ring and a plurality of columns, and is directly connected with the volute; the column is wing-shaped and cannot be rotated, and is also called a fixed guide vane. The water guiding mechanism is composed of a movable guide vane, a speed regulating ring, a crank arm, a connecting rod and the like. The runner is directly connected to the main shaft (see the main shaft of the turbine) and is a rotating part of the turbine. The runner consists of an upper crown, a lower ring, a drain cone and a number of fixed blades. The shape and the fit of each component are based on The head used varies. The draft tube is a turbine draining component that directs the flow of water from the outlet of the runner to the downstream, generally elbow-shaped, and the small turbine is usually a straight-conical draft tube.

1,suitable for high head,small flow and flow changes in large runoff hydropower station;

2.With the power plant investment is small,compact units structure characteristics;

3.Has the efficiency changes smoothly,operating a wide range,even in the 15%-20%load is reduced efficiency;

4.Suitable for high head amall flow station in mountain area;

5.A unit construction,simple restrictions without cavitation condition,the advantages of stable ooperation,less investment,construction area.
