Abstract

UN APARATO PARA LA PREVENCION DE FATIGA TERMICA PARA BOMBAS DE ALTA TEMPERATURA QUE CONSTA DE UN IMPULSOR (3) EN UN ALOJAMIENTO DE BOMBA DE ALTA TEMPERATURA, UN EJE DE LA BOMBA (4) GIRATORIAMENTE SOSTENIDO POR UN GORRON (11) DE UN COJINETE SUMERGIDO (10) Y UNA PROYECCION DE UN ARBOL A TRAVES DE UN AGUJERO (12) DE UNA CUBIERTA DE BASTIDOR (2) Y UN MEDIO DE SELLADO DE ARBOL. EL MEDIO DE SELLADO DEL ARBOL (14) ESTA EQUIPADO CON UNA CAMARA DE SELLADO DE ARBOL (6) QUE SE SUMINISTRA CON UN LIQUIDO DE PURGA DE SELLADO DE BAJA TEMPERATURA (A), Y UNA PARTE DE DICHO LIQUIDO DE PURGA DE SELLADO (A) FLUYE EN EL BASTIDOR DE LA BOMBA MENCIONADO A TRAVES DEL ARBOL MENCIONADO POR EL AGUJERO (12). SE PROPORCIONA UN CALENTADOR (20) DENTRO DE LA BOMBA DE ALTA TEMPERATURA MENCIONADA, DICHO CALENTADOR AUMENTA LA TEMPERATURA DEL LIQUIDO DE PURGA DE SELLADO DE BAJA TEMPERATURA (A) ANTES DE QUE EL MENCIONADO LIQUIDO DE PURGA DE SELLADO FLUYA EN EL BASTIDOR DE LA BOMBA MENCIONADA UTILIZANDO EL LIQUIDO DE BOMBEO DEALTA TEMPERATURA (B).
