Hydraulic Generating Tubular Turbine 10kw Hydro Generator with Resonable Price

Tubular turbine has been divided into Bulb tubular and shaft extension tubular according to the arrangement. Suit to low water head 2-25 meters, and with certain big flow, normally divided into fixed blades and adjustable blades turbine. Main components including: runner, draft cone, water chamber, guide vane, bearing, and main shaft. The spiral case could be steel or concrete. The runner diameter we can manufacture is from 80cm to 6.0meters, with rated output 200Kw to 60Mw.

Turbine units normally be horizontal shaft arrangement. Generator equipped with same or different shaft, with Anyway, they will share the same rotating speed. If specially required,

a speed increase gear could be equipped between turbine and generator in order to smaller the generator size.

Specification:

Fixed blade type: GD; Adjustable blade type: GZ
The diameter of the runner: 0.8m-6m;
Suitable water head: H =2m- 25m;

Suitable flow: Q =1.0m3/s- 250m3/s;
Capacity of the generator unit: 200kw -60MW.

The tubular turbines are the best selection for exploitation of tidal power and hydraulic power with extremely low heads and extremely large flow rates. They have large discharge, high specific and high efficiency, and need less excavation. They have been classified into Bulb, Pit, Siphon and "S" types in the light of their structural types.

Tubular turbine generally has two categories: fully tubular and half tubular. The half Tubular turbine is divided into bulb, pit and shaft extension types, etc.

The generator’s rotor of the full tubular type unit is on the outer circle of turbine’s runner, whose application is less because of its difficult sealing.

For half Tubular turbine, the generator is separate from the hydro turbine:
Tubular type: Generator set is installed inside the airtight bulb body, which has a compact structure, straight passage shape, high hydraulic efficiency and so it is widely used.

Shaft extension type tubular unit: The generator is installed outside; the main shaft of turbine extends to the outside of the draft tube.
Pit type tubular unit: The generator is installed inside a pit.

Tubular turbine adopts conical water distributor that mainly includes the inner and outer chambers of the guide vane, guide vane, guide vane arm, connecting rod and control ring, etc. The guide blade shaft of conical water distributor is layout into 60 ~ 70 degree angle with the unit shaft. The bearings supporting the guide vane are seated on the guide vane inner and outer chamber. The guide vane composes a conical surface for adjusting the water flow or stooping the unit. In order to reduce the water leakage losses on the guide vane end surface, the surface of the guide vane inner and outer chamber are spherical surface.

Bulb turbines are designed into the water delivery tube. A large bulb is centered in the water pipe, which holds the generator, wicket gate and runner. Tubular turbines are a fully axial design, whereas Kaplan turbines have a radial wicket gate.

Pit turbines are bulb turbines with a gearbox. This allows for a smaller generator and bulb.

S type turbines eliminate the need for a bulb housing by placing the generator outside of the water channel. This is accomplished with a jog in the water channel and a shaft connecting the runner and generator.
