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.

1 . Peripheral pump-turbine formed by a mechanism which drives a fluid, comprising:
 two wheels meshed with one another such that one moves the other in a synchronized manner,   wherein the wheels laterally incorporate two or more blades fitting in matching recesses arranged on their sides intercalated between said blades in said meshed rotation,   wherein said wheels are housed inside casings between which respective openings for intake and discharge of fluid are formed.   
     
     
         2 . Peripheral pump-turbine according to  claim 1 , wherein a dimension of the openings is defined by a length calculated as a sum of:
 a horizontal projection of a distance between centers of the wheels,   a product of a radius times a cosine of a semiangle formed by two consecutive blades of one of the wheels,   a product of the radius times the cosine of the semiangle formed by two consecutive blades of the other wheel.   
     
     
         3 . Peripheral pump-turbine according to  claim 1 , wherein the casings partially cover upper and lower portions of the wheels with blades, thus determining the fluid intake and discharge openings, laterally demarcated by two front and rear frontal covers, through which shafts of the wheels emerge and through which the movement is applied thereto. 
     
     
         4 . Peripheral pump-turbine according to  claim 1 , wherein the wheels incorporate teeth to allow meshing thereof, the teeth being incorporated therein arranged between the blades and the recesses. 
     
     
         5 . Peripheral pump-turbine according to  claim 1 , wherein the wheels mesh by means of respective pinions which are lubricated and enclosed in a compartment, integrally coupled to shafts thereof and located in an outer portion of the casing. 
     
     
         6 . Peripheral pump-turbine according to  claim 1 , wherein an angle of separation of the blades of each wheel determines an angle of contact of the casings with respect to the wheels.
