Abstract

LA INVENCION SE REFIERE A UNA BOMBA DE ANILLO LIQUIDO CONICO QUE TIENE UNA O MAS ESTRUCTURAS DE SOPORTE CON ANGULOS CONICOS EN EL RANGO DE 15 A 75 GRADOS. ESTOS ANGULOS CONICOS SON SUSTANCIALMENTE MAS GRANDES QUE LOS ANGULOS CONICOS PREVIAMENTE UTILIZADOS (LO MAS NORMAL ALREDEDOR DE 8 (GRADOS) C). LOS ANGULOS CONICOS GRANDES DE ESTA INVENCION PROPORCIONAN AL FLUJO DEL FLUIDO ENTRE EL CONO Y EL ROTOR COMPONENTES SIGNIFICATIVAS DE VELOCIDAD AXIAL Y RADIAL. LOS ANGULOS CONICOS GRANDES TAMBIEN PERMITEN QUE LAS ESTRUCTURAS DE SOPORTE SE HAGAN MAS CORTAS AXIALMENTE, LO CUAL TIENE UN NUMERO DE IMPORTANTES VENTAJAS TALES COMO EL ACORTAMIENTO DE LA LONGITUD NO APOYADA DEL EJE DE ROTOR. ESTOS ATRIBUTOS DE LAS PRESENTES BOMBAS SON UTILES PARA PROPOSITOS TALES COMO PERMITIR QUE LAS RELACIONES LONGITUD-DIAMETRO DE LAS BOMBAS AUMENTEN ECONOMICAMENTE. ADICIONALMENTE, LAS BOMBAS DE ESTA INVENCION CONSERVAN MUCHOS DE LOS ATRIBUTOS DESEABLES DE LAS BOMBAS CONICAS.
