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).CENTRIFUGAL PUMP FOR THE EXTRACTION OF, IN PARTICULAR, HOT LIQUIDS WITH AT LEAST A WAVE RUNNER THROUGH THE OUTSIDE OF THE PUMP HOUSING AND INSULATION OF THE WAVE CORRIDOR BY A RING JOINT AS WELL AS A COLD CLEANING FORCING CURRENT, FROM THE EXTRACTION MEANS, FOR THE SLIP RING JOINT. THIS CURRENT IS TAKEN FROM A HIGHER PRESSURE ZONE, THE PRESSURE CHAMBER (3), THE SPIRAL CHAMBER (6) OR THE SPIRAL SIDE CHAMBER (7) OF THE PUMP AND IS CONDUCTED THROUGH AT LEAST ONE CHANNEL (8) PROVIDED IN A HOUSING COVER (10), ONE BETWEEN THE HOUSING COVER (10) AND A CIRCULAR OPENING (13) ON THE SIDE OF THE DRIVE WHEEL, INSERTED IN THE HOUSING COVER AND CONSTITUTED BY HOUSINGS INTERMEDIATE (11) AND DRIVES FROM THIS OPENING, NEAR THE DENSE SURFACE OF THE SLIDING RING JOINT (14, 15), TO THE CHAMBER OF THE BOARD CONTAINING THE SLIDING RING GASKET. THE CURRENT, AFTER CROSSING THE JOINT CAMERA (16) IS LEADED BY A CHOKE HOLE (17) TO A CHAMBER OF LESS PRESSURE IN THE PUMP. TO IMPROVE THE EFFECT OF CLEANING AND COOLING IT IS PROVIDED ACCORDING TO THE INVENTION BETWEEN THE CHANNEL (8) AND THE CIRCULAR OPENING (13) THIS ARRANGEMENT A CIRCULAR DISTRIBUTION CHAMBER WHOSE WIDTH IS A MULTIPLE OF THE ADJUSTED CIRCULAR OPENING (13) OF THE RADIAL ADDRESS ON THE SCOPE OF THE DENSE SURFACE OF THE SLIDING RING JOINT (14, 15) AND THAT THE FALL OF PRESSURE IN THE STRANGULATION HOLE (17) IS SEVERAL TIMES GREATER THAN THE FALL OF PRESSURE OF THE MAJOR AREA PRESSURE (7) REGARDING THE BOARD CHAMBER (14).
