Abstract

UNA BOMBA DE VACIO DE ANILLO LIQUIDO QUE INCLUYE UN ALOJAMIENTO COMPUESTO POR DOS PAREDES OPUESTAS Y ESPACIADAS POR UNA PARED ANULAR QUE DEFINE UN CAMARA; DE UN EJE QUE SE EXTIENDE EN LA CAMARA DE LA BOMBA DE VACIO; DE UN ROTOR MONTADO EN EL EJE Y DISPUESTO EXCENTRICAMENTE EN LA CAMARA; EL ROTOR INCLUYE UNA PARTE CENTRAL DEL MISMO, Y DE UNA CANTIDAD DETERMINADA DE PALAS PROVISTAS DE AL MENOS UN BORDE LATERAL ADYACENTE A LAS PAREDES EXTREMAS FRENTE A LA PARED ANULAR, LOS BORDES LATERALES Y LAS PAREDES EXTREMAS FORMAN UN ESPACIO LIBRE ENTRE ELLAS; Y EL ESPACIO LIBRE ENTRE LOS BORDES Y AL MENOS UNA DE LAS PAREDES EXTREMAS ADYACENTES DE LA CAMARA DE LA BOMBA DE VACIO, AUMENTAN HACIA LA PARED ANULAR. TAMBIEN SE PROPORCIONA UNA COMBINACION DE LA BOMBA DE VACIO DE ANILLO LIQUIDO CON UNA BOMBA CENTRIFUGA PARA BOMBEAR LIQUIDOS MULTIFASES, TALES COMO GASES Y SOLIDOS QUE CONTIENEN SUSPENSIONES DE FIBRAS DE PULPA Y DE PAPEL INDUSTRIAL
