Product Details
Tubular turbine is widely used in a hydro power stations with the head of 2-30meters,The blades are fixed or can adust manualy the efficient turbine of this kind can produce a large quantity of water flow which passes unimpededly.
Tubular turbine is the horizontal shaft water turbine of which the flow channel approximates straight, it does not have a water diversion volute and the blades could be into fixed or rotary. According to the different types of generator device, it could be classified as rim generator turbine and half-tubular turbine. The rotor of rim generator turbine was directly installed on the rim of running wheel. The advantages are that, the flow channel is straight, the water flow is strong and high efficiency. But the linear velocity and perimeter of outer rim of blades is big, thus the rotating seal is difficult. Currently, the rim generator turbine model has been rarely used. The half-tubular turbine was classified into S-type turbine、pit turbine and bulb turbine. The structure of S-type turbine and pit turbine are simple, maintenance is easy but is low efficiency. They are applicable for small-scaled hydropower stations generally. At present, the bulb turbine has been widely used because of compact structure, steady operation and high efficiency. The power-making device was decorated in a steel light bulb which was flowed by water, the turbine and generator could connect directly or through the increasing gear.
