Abstract

ESTE INVENTO SE REFIERE A UNA BOMBA CENTRIFUGA DE AUTO-CEBADO (1) QUE CONSTA DE UNA CAJA DE ESTATOR (2) CON UNA PUERTA DE DESCARGA (5) Y UNA PUERTA DE DERRAME Y UN IMPULSOR DE PALETAS RADIAL-CENTRIFUGO (7). SE PROPORCIONA UN EYECTOR (16) DENTRO DE LA CAJA (2) Y CONSTA DE UNA CAMARA DE INDUCCION QUE SE CONECTA A LA PUERTA DE TOMA (3), UNA BOQUILLA DE ARRASTRE (17) CONECTADA A LA CAMARA INTERNA DE LA CAJA DEL ESTATOR Y UN CONDUCTO DE DIFUSION (19) QUE ES COAXIAL AL IMPULSOR (7) Y QUE ESTA CONECTADO A SU SECCION DE ENTRADA. SE PROPORCIONA UN TRANSPORTADOR DESPUES DEL IMPULSOR Y CONSTA DE AL MENOS UN CANAL DE TRANSPORTE RADIALCENTRIPETO (24) Y UNA SECCION DE DERRAME ANULAR QUE SE EXTIENDE PERIFERICAMENTE AL CONDUCTO DE DIFUSION DEL EYECTOR. EL TRANSPORTADOR (24) TIENE UNA CONFIGURACION QUE SE PUEDE ADAPTAR PARA DIRIGIR EL FLUJO QUE ABANDONA EL IMPULSOR HACIA UNA PORCION CENTRAL DE LA CAJA QUE ES ADYACENTE A LA PORCION EXTERIOR DEL CONDUCTO DE DIFUSION (19) Y ESTA DISTANCIADA DE LA PUERTA DEDERRAME (5), Y PARA HACER DICHO FLUJO LAMINAR ASI COMO PARA FACILITAR LA SEPARACION DEL AIRE Y SU MIGRACION A TRAVES DE LA PUERTA DE DERRAME (5).
