Description

HYDRAULIC TURBINE WITH CIRCULAR FLOW
The invention refers to an assembly consisting of a rotor (rigidly mounted on a shaft) and a stator, which transform the potential energy of a fluid into mechanical energy.
There are known the classical turbines that use a great volume of fluid in order to obtain mechanical energy.
The disadvantages of the known turbines are:
- They need great volumes of fluid.
- The fluid actions upon the turbine for a short time, being released at atmospheric pressure, into the escape drains, where the potential energy is dissipated, generally being absorbed by the hydrotechnical constructions.
- If it uses water as working fluid, it needs complicated hydrotechnical constructions with high investment costs.
The purpose of the invention is to achieve a turbine that functioning with relatively reduced volumes of fluids, ensures a prolonged action of the fluid upon the rotor-stator assembly, ensuring a more efficient transformation of the potential energy with a higher efficiency compared to the classical systems and in the same time a simplification of the hydrotechnical constructions and implicitly of the investment costs.
The problem that this invention resolves is the optimization of the use of potential energy, especially for the systems with water feeding with successive breakages of energy and in the same time obtaining higher quantities of electric energy in ecological conditions, with more reduced consumption of water.
The turbine, according to the invention has the following advantages:
- It needs more reduced quantities of actuating fluid.
- It ensures the action of the fluid upon the turbine and transfer of the energy on about 90% of the circumference of the rotor-stator assembly with a superior efficiency than the classical turbines.
- It eliminates the necessity of a more complicated hydrological works.
- It eliminates the water waste by maximization of the transformation efficiency of the potential energy.
- It permits the decrease of the cost price of the primary energy necessary for producing electric energy,
- The reduction of the ecological impact of the processes that produce electric energy.
Hereinafter, we give an example of invention achieving, in connection with Figure 1 and 2 that represent:
- Figure 1, plan view with a section of the hydraulic turbine with circular flow.
- Figure 2 -section A-A through the hydraulic turbine with circular flow.
According to the invention, the hydraulic turbine with circular flow, 1 - self known is composed of stator 2, self known, foreseen with a access hole for water 3, self known, through which the water under pressure introduced inside the turbine actions upon the vanes 4, selves known, mounted on rotor 5, self know, rigidly mounted on the axis of the turbine 6, self known, enabling the rotation of the vanes successively auctioned by the water stream, in the space delimited by the inferior cover of the stator 7, self known, the ring of the stator 8, self known, the superior cover of the stator 9, self known, the action of the stream being re-directed successively to the vanes of the turbine by the deflectors 10, selves known and afterwards after the most potential energy is transformed into mechanical work, the fluid leaves the turbine through the evacuation hole 11, self known, the evacuation of the water being imposed by a sector that obstructs the space between the stator and vanes in the evacuation area of the water 12, self known, by the guiding-sealing ring applied on the inferior cover of the stator that closes the existent space between the inferior cover and vanes in the evacuation area of the water 13, self known, and the guiding-sealing ring applied on the superior wall in the evacuation area of the water 14, self known.
