All-purpose hydroturbine

Abstract

A universal water-turbine engine pertains to an impact water-turbine engine which converts pressure energy of current to kinetic energy and converts the kinetic energy to rotating mechanical energy in the hydraulic machinery; the water-turbine engine consists of a or a plurality of jet orifices, a device corresponding to the jet orifices, a or a plurality of turning wheels arranged on a main axis for the universal water-turbine engine, a tailrace arranged under the turning wheel, a speed governor, a driving device and other parts. The water-turbine engine can develop and exploit all waterpower resources and has high efficiency, large capacity, safe and reliable performance, simple and reasonable structure as well as low manufacturing cost; the application of the water-turbine engine significantly promotes the current development and exploitation of the waterpower resource, thus being capable of marking a new epoch of rapid development of the hydroelectric power industry.

Description

Technical field [0001] The invention belongs to hydraulic machinery, which converts the pressure energy of water flow into kinetic energy, and then converts the kinetic energy into rotational mechanical energy. Background technique [0002] At present, all kinds of water turbines in the reaction type used in hydropower production can not only be used within their specific water head and flow range, but also can only achieve higher efficiency under optimal working conditions. And its structure is complex and huge, the number of units is large, the amount of civil works is large, and the cost is high. This not only makes the manufacture and transportation of the equipment very difficult, but also has high requirements on the geological and terrain conditions of the developed hydropower resources. Thereby, the development and utilization process of water energy resources is seriously restricted, and even some water energy resources cannot be developed at all. [0003] In the ...

AI Technical Summary

Problems solved by technology

The disadvantage of this turbine is that the water flow after adjusting the ram or guide vane has become a high-speed water flow, and the high-speed water flow must pass through the arc-shaped drainage surface before it can impact the runner blades

Its disadvantages are: when the water flows into the right-angled edge of the speed-up hole, due to the penetration effect, the streamline cannot suddenly turn, but can only be gradually bent, so that the water flow shrinks, resulting in a certain degree of loss of kinetic energy

Its shortcomings are: because there is no injection device, the water flow entering the blade only has the kinetic energy formed by the pressure energy and the small flow velocity in the pipeline, so it will not generate a large momentum

The disadvantage of this water turbine is that when the water flowing out of the blade tube of the upper rotor hits the arc-shaped blades of the lower rotor, the water flow will directly flow out of the bottom of the arc-shaped blades, so that its kinetic energy cannot be effectively transferred to lower rotor blades

Moreover, the overall structure of the turbine is extremely unreasonable

[0009] Due to the serious shortage of the above water turbines, the development and utilization of water energy resources is still very slow, so that the clean, cheap and renewable water energy resources will be lost for a long time, and cannot benefit mankind.
