Abstract
BOMBA CENTRIFUGA PARA LA EXTRACCION DE, EN PARTICULAR, LIQUIDOS CALIENTES CON, POR LO MENOS, UN CORREDOR DE ONDAS A TRAVES DE LA CARCASA DE LA BOMBA QUE SE DIRIGE HACIA AFUERA Y AISLAMIENTO DEL CORREDOR DE ONDAS POR MEDIO DE UNA JUNTA DE ANILLO DESLIZANTE, ASI COMO UNA CORRIENTE BIFURCADA LIMPIADORA Y FRIA, PROCEDENTE DEL MEDIO DE EXTRACCION, PARA LA JUNTA DE ANILLO DESLIZANTE. ESTA CORRIENTE SE TOMA DE UNA ZONA DE MAYOR PRESION, LA CAMARA DE PRESION (3), LA CAMARA EN ESPIRAL (6) O LA CAMARA DE LADOS EN ESPIRAL (7) DE LA BOMBA Y SE CONDUCE A TRAVES DE, AL MENOS, UN CANAL (8) PREVISTO EN UNA TAPA DE LA CARCASA (10), UNO ENTRE LA TAPA DE LA CARCASA (10) Y UNA ABERTURA CIRCULAR (13) DEL LADO DE LA RUEDA MOTRIZ, INSERTADO EN LA TAPA DE LA CARCASA Y CONSTITUIDO POR CARCASAS INTERMEDIAS (11) Y SE CONDUCE DE ESTA ABERTURA, CERCA DE LA SUPERFICIE DENSA DE LA JUNTA DE ANILLO DESLIZANTE (14, 15), A LA CAMARA DE LA JUNTA QUE CONTIENE LA JUNTA DE ANILLO DESLIZANTE. LA CORRIENTE, DESPUES DE ATRAVESAR LACAMARA DE LA JUNTA (16) ES CONDUCIDA POR UN ORIFICIO DE ESTRANGULAMIENTO (17) A UNA CAMARA DE MENOR PRESION DE LA BOMBA. PARA MEJORAR EL EFECTO DE LIMPIEZA Y ENFRIADO ESTA PREVISTO SEGUN LA INVENCION QUE ENTRE EL CANAL (8) Y LA ABERTURA CIRCULAR (13) ESTE DISPUESTA UNA CAMARA DE DISTRIBUCION CIRCULAR CUYA ANCHURA ES UN MULTIPLO DE LA ABERTURA CIRCULAR AJUSTADA (13) CON UN COMPONENTE DE LA DIRECCION RADIAL SOBRE EL AMBITO DE LA SUPERFICIE DENSA DE LA JUNTA DE ANILLO DESLIZANTE (14, 15) Y QUE LA CAIDA DE PRESION EN EL ORIFICIO DE ESTRANGULAMIENTO (17) ES VARIAS VECES MAYOR QUE LA CAIDA DE PRESION DE LA ZONA DE MAYOR PRESION (7) CON RESPECTO A LA CAMARA DE LA JUNTA (14).
