Abstract

BOMBA CENTRIFUGA MULTICELULAR SUMERGIBLE, DEL TIPO DE LAS QUE COMPRENDEN UN ELECTROMOTOR SUPERIOR, DE EJE VERTICAL, UN CUERPO DE BOMBA, COAXIAL AL ELECTROMOTOR Y DISPUESTO POR DEBAJO DEL MISMO Y UN PIE INFERIOR SITUADO POR DEBAJO DEL CUERPO BOMBA, ESTANDO EL CONJUNTO DE ELECTROMOTOR Y DE CUERPO DE BOMBA ENCERRADO DENTRO DE UNA ENVOLVENTE EXTERIOR CILINDRICA, CON EL ARBOL DEL ELECTROMOTOR DISPUESTO ATRAVESANDO MULTIPLES RODETES Y PROVISTO DE UN SELLO MECANICO CONVENCIONAL DE HERMETICIDAD, QUE IMPIDE EL ACCESO DEL AGUA AL MOTOR. EL AGUA ES ASPIRADA A TRAVES DE ORIFICIOS PRACTICADOS EN DICHO PIE, ES CENTRIFUGADA POR EL CUERPO DE BOMBA, ES IMPULSADA A TRAVES DE UN ESPACIO COMPRENDIDO ENTRE EL ELECTROMOTOR Y LA ENVOLVENTE EXTERIOR Y SALE POR UNA ABERTURA SITUADA EN EL EXTREMO SUPERIOR DE LA BOMBA. EL ELECTROMOTOR ESTA CERRADO INFERIORMENTE DE FORMA HERMETICA POR UNA BASE ATRAVESADA POR EL ARBOL DEL ELECTROMOTOR Y DOTADA DE UNA CAMARA ESTANCA EN LA QUE ESTA DISPUESTO UN SEGUNDO SELLO MECANICO DECIERRE DEL MOTOR, QUE TRABAJA DE CIERRE DE SEGURIDAD Y EN FORMA INVERTIDA RESPECTO A LA PRESION. DICHA BASE DE CIERRE HERMETICO INFERIOR DEL MOTOR, CONSTITUYE UN CARTER ADAPTADO PARA CONTENER UNA CIERTA CANTIDAD DE ACEITE, QUE BAÑA LA PARTE INFERIOR DEL BOBINADO DEL MOTOR Y EL COJINETE INFERIOR DE GIRO DEL ARBOL DEL ELECTROMOTOR. LA CITADA ENVOLVENTE EXTERIOR CILINDRICA ESTA DISPUESTA ROSCADA SOBRE EL CITADO PIE INFERIOR.
