Peripheral pump-turbine

Abstract

A peripheral pump-turbine including two wheels meshed with one another, laterally incorporating two or more blades fitting in matching recesses intercalated between said blades, being housed in a casing provided with fluid intake and discharge openings, where the wheels can incorporate teeth arranged between the blades and the recesses to allow the meshing thereof, and where the wheels can mesh by means of pinions integrally coupled to the shafts thereof in the outer portion of the casing.

Description

TECHNICAL FIELD OF THE INVENTION[0001]The invention relates to a peripheral pump-turbine providing significant advantages and novelty features to the intended function with respect to other similar devices, mechanisms and systems currently known on the market.[0002]More particularly, the invention focuses on a fluid driving mechanism formed by two wheels with blades that rotate in a meshed manner, the mechanism is at the same time a peripheral turbine and pump, since, depending on the rotation direction of said wheels, the mechanism acts as a pump or a turbine where appropriate, integrating both types of machine in one and the same mechanism.[0003]The field of application of the present invention is encompassed within the technical sector of the industry dedicated to manufacturing hydraulic turbines and pumps.BACKGROUND OF THE INVENTION[0004]Today and as a reference to the state of the art, it must be highlighted that, although there are several types of turbines and pumps of the ty...

AI Technical Summary

Benefits of technology

"The invention is a hydraulic machine that solves the problem of being difficult to assemble and having limited intake and discharge cavities in previous designs. It has larger intake and discharge cavities, allowing for faster assembly and operation. The machine has a unique structure with divided casing and separate parts for the intake and discharge openings, making it easier and more cost-effective to manufacture and assemble. The machine can be used as a pump or a turbine depending on the fluid being driven. The blades are designed to prevent wear and improve pumping efficiency. The invention has a high volume of fluid intake and discharge, making it useful for applications such as extinguishing fires at high altitudes."

Problems solved by technology

Various applications relating to hydraulic machines are known such as the patent application publication number U.S. 2002061256 in which it describes a pair of wheels comprising blades which are coupled to recesses made on the wheels themselves; but drawbacks such as the complexity for designing and manufacturing the enveloping casing of said hydraulic machine, as well as a relatively small volume of intake and discharge flow limiting the use to small hydraulic installations are observed.

Patent application publication number ES 2131706 describes a pair of meshed wheels and a series of measurements relating to the dimensions of the teeth, fillet radii, etc. of said meshed wheels which can comprise a series of blades acting as the drive in a pump type hydraulic machine, but said application does not describe the dimensions of the fluid intake and discharge cavities nor the shape of the casing enveloping said device; making it highly difficult to be put into service.

Therefore, it is observed that, there are several drawbacks mainly relating to the use of pump-turbines of this type for installations needing to move large volume of flow, mainly in hydroelectric plants; since the main focus of the mentioned prior arts relate to small machines intended for moving small volumes of fluids.
