Kaplan turbine is widely used in a hydro power stations with the head of 2-30 meters. It is equipped with a vertical axle. There are three different types of this kind in which there is anopen trough or apressure trough or closed concrete worm-shelltrough. The turbine is made up of several propellers or manualy-ajusted blades. The water pipe at the end is vertical cone-shaped or elbow-shaped. The turbine with a diameter of 1000mm is vertical coneshaped. Therefore, it is fit for a small hydro power station with low head and load.

Kaplan turbine has a blade rotating structure, called guide vanes or wicket gates, inside the turbine runner, which can rotate comparatively to the runner. According to different load and water flow, the blades cooperate with guide vanes to form a double adjustment, and obtain higher hydro efficiency and stable operation and expand the scope of operation efficiency. Therefore, it is suitable for water flow which changes greatly, especially for power station with great power output difference. It requires 3-30 m to operate and is widely used in electric power station with low water flow but great capacity.
