Abstract

The invention relates to an assembly consisting of a rotor and a stator, which transforms the potential energy of a fluid into mechanical energy. According to the invention, the hydraulic turbine consists of a stator (2) wherein there is placed a shaft (6) to which there is reinforced a rotor (5) on which there are fastened some blades (4) driven by the water introduced under pressure through a man-hole (3) allowing the access into the space delimited by a lower cover (7), a ring (8) and an upper cover (9) of the stator (2), the jet of fluid being successively redirected towards the blades (4) by means of some deflectors (10) and, after the most part of the potential energy is transformed into mechanical work, the fluid leaves the turbine through a discharge hole (11), the water discharge being possible due to a sector (12) fastened on the stator (2) in the discharge area which obturates the space between the stator (2) and blades (4), of a guiding-sealing ring (13) applied on the lower cover (7) in order to close the space existing between the lower cover (7) and the blades (4) in the water discharge area and that of a guiding-sealing ring (14) applied on the upper cover (9) which closes the space existing between the upper cover (9) and the blades (4) in the water discharge area.

Silaghi turbine

The invention relates to an assembly consisting of a rotor (secured to a shaft) and a stator, which converts the potential energy of a fluid into mechanical energy.

I feel familiar with classic turbines that use a large volume of fluid to obtain mechanical energy.

Disadvantages of known turbines:

- Requires large volumes of fluid.

- The fluid acts on the turbine for a short period of time being released at atmospheric pressure, in the exhaust channels, where the potential energy is dissipated, usually being absorbed by the hydrotechnical constructions.

- Requires in case of use of water as working fluid of some complicated hydrotechnical constructions with high investment costs.

The object of the invention is to provide a turbine which, operating with relatively small volumes of fluid, ensures a longer action of the fluid on the rotor assembly, ensuring a more efficient transformation of potential energy with a higher efficiency than conventional systems and at the same time simplifying hydrotechnical constructions. and implicitly of investment costs.

The problem solved by the invention is the optimization of the use of potential energy, especially in the case of water supply systems with successive pressure breaks, but at the same time obtaining a larger amount of electricity in ecological conditions, with lower water consumption.

The turbine according to the invention has the following advantages:

- Requires smaller amounts of actuating fluid.

- Ensures the action of the fluid on the turbine and the transfer of energy on about 90% of the circumference of the rotor-stator assembly with a higher efficiency than conventional turbines.

- Eliminates the need for complicated hydrological work.

- Eliminate waste of water by maximizing the efficiency of potential energy transformation.

- It allows to decrease the cost price of the primary energy required in the production of electricity.

- Reducing the ecological impact of electricity production processes.
