FR3017423A1 - HYDRAULIC MECHANISM COMPRISING ANOTHER TWO ROTOR TURBINES WITH IMPROVED DYNAMIC PERFORMANCE THAN TWO INTERNAL CHAMBERS ACTUATING INVERSION IN COMPRESSION AND DECOMPRESSION </ P> - Google Patents

Abstract

Hydraulic mechanism composed among others of a turbine with two rotors with improved dynamic performances thanks to two internal chambers acting inversely in compression and decompression (figure 2). Hydraulic mechanism actuated by a fluid under pressure. To this hydraulic mechanism is associated a bypass allowing the supply of fluid under pressure in cases where flow and pressure are insufficient. The hydraulic mechanism according to the invention is particularly intended to improve the performance of a mechanical reduction device that synchronously actuates a rotary pump.

Description

The invention relates to a hydraulic mechanism (FIG. 1) composed of a turbine (10 ') equipped with two rotors (2 and 4) actuated by the pressure and the flow rate of an incoming fluid (6), fluid coming from a domestic, industrial or agricultural and pressure network (16). A feature of the present invention is the perfectly synchronous activation of the rotors (2 and 4) as soon as a tap point, for example (14), is placed downstream on the network (16). Another feature of the present invention is that the turbine (10 ') is equipped with a conduit (11) placed in shunt (12 & 13) between the inlet (6) and the outlet (6') of the fluid under pressure of the turbine (10 ') allowing the circulation of the fluid at least when the rotors (2 and 4) of the turbine (10') can not be actuated, or by a lack of pressure or flow of the fluid (16) entering in (6). Another feature of the present invention is the particular design of the chamber (17) conical narrower shape from the entry of the fluid (16) entering (6). Another feature of the present invention is the particular design of the chamber (17 '), of conical shape more flared from the entrance of the fluid (16) outgoing at (6').

Thus, thanks to the particular and original designs of the chambers (17) and (17 '), the dynamic characteristics of the turbine (10') are improved. The invention falls within the technical scope of turbines and water motors and other fluids. Traditionally a turbine may be equipped with one or more rotors in the form of blades or gears.

In the context of the present invention, the turbine (10 ') is equipped with two rotors (2 and 4) of the same dimensional characteristics perfectly nested. The rotor (2) is positioned in free rotation on a static shaft (3) fixed to the body (10) of the turbine (10 '). The rotor (4) is keyed on a free rotation shaft (1) and integral with a reduction mechanism (18) consisting of two gears of different diameters and perfectly interlocked, the largest pinion (19) connected at its center to the tree (1). Thus, as soon as the turbine (10 ') is put into action under the effect of the pressure and the flow rate of the fluid (16) entering at (6), the rotors (2 and 4) and the gearing mechanism (18) are synchronically put into action.

Another feature of the present invention is that the rotors (2 and 4) are housed in a sealed housing (10) of cylindrical shape called body of the turbine (10 '). Other features of the invention are the positioning and the fitting accuracies of the rotors (2 and 4) with respect to two clevises (8 and 8 ') themselves integral with the housing (10) as well as the dimensional and shape characteristics. very different from the two clevises (8 and 8 ') Each of the two clevises is disposed on either side of the rotors (2 and 4), they thus allow the regulation of the incoming and outgoing volumes of the fluid under pressure (16).

At the gearing mechanism (18) it can be coupled any other mechanism in rotation and especially a pump, in this respect the present invention is to be considered as a hydraulic installation accessory, or a plumbing system individual, collective, industrial or agricultural. In the field of water recovery, such as rainwater or gray wastewater, it is usually used a pump to allow their transport to places of reuse. This pump can be electric, pneumatic, mechanical, in all these cases it is necessary to have adequate energy and secure facilities. The present invention proposes to respond only mechanically and synchronously to the disadvantages of existing installations that systematically use external energies.

It is within the framework of a first inventive step that it has been imagined to use a dormant energy, punctual and available in almost any type of construction, the pressure of the drinking water supply network. As part of a second inventive step it has been imagined to use this pressure present in the water supply networks such as drinking water and whose energy is released as needed, at each opening of a point of water. As part of a third inventive step it was imagined to optimize the operation of the turbine (10 ') thanks to the particular design of the chambers (17 and 17') making it possible to increase both the pressure and the speed fluid circulation (16) for example drinking water under pressure, these chambers determine the shapes and volumes of the inlet (6) and outlet (6 ') of the fluid (16) in the turbine (10'). As part of a fourth inventive step it was imagined to install a bypass (11) of the fluid (16) between the upstream (13) and the downstream (12) of the turbine (10 '). when the fluid demand (16) is not sufficient to operate the rotors (2 and 4) of the turbine (10 '), a sufficient amount of the fluid (16) is derived to supply the demand (14).

As part of a fifth inventive step, it has been imagined to connect the shaft (1) of the turbine (10 ') to a reduction mechanism (18) intended to increase the operating performance of a rotating mechanism such as a pump, an engine, a dynamo.
