Abstract

UNA BOMBA CENTRIFUGA PARA BOMBEAR SUSPENSIONES DE FIBRA QUE INCLUYE UN ALOJAMIENTO DE BOMBEO CENTRIFUGO (50) QUE TIENE UNA ENTRADA (52) Y UNA SALIDA PARA LA SUSPENSION Y UN IMPULSOR CENTRIFUGO DENTRO DEL ALOJAMIENTO DE BOMBEO CENTRIFUGO. UNA BOMBA DE VACIO (70) SE COLOCA ADYACENTE AL ALOJAMIENTO DE BOMBEO CENTRIFUGO (50) E INCLUYE UNA CAMARA DE BOMBA DE VACIO DEFINIDA POR PAREDES LATERALES OPUESTAS PRIMERA Y SEGUNDA (110, 112) Y UN OTRO DE BOMBA DE VACIO MONTANDO EXCENTRICAMENTE DENTRO DE LA CAMARA DE BOMBA DE VACIO. EL ROTOR TIENE BORDES LATERALES OPUESTOS QUE SE EXTIENDEN RADIALMENTE FRENTE A LAS PAREDES LATERALES DE LA BOMBA DE VACIO (110, 112) PARA PROPORCIONAR UN LIQUIDO DE SELLADO A LA HOLGURA (122) ENTRE EL ROTOR Y AL MENOS UNA DE LAS PAREDES LATERALES DE LA CAMARA DE LA BOMBA DE VACIO (76). SE PUEDE SUMINISTRAR LIQUIDO DE NIVEL A TRAVES DE LOS MISMOS CONDUCTOS DEL LIQUIDO DE SELLADO O SEPARADOS DEL MISMO. LA BOMBA CENTRIFUGA PUEDE INCLUIR UN IMPULSOR FLUIDIZANTE.
