Abstract

CONDUCTO DE SALIDA PARA BOMBAS CENTRIFUGAS CON GRAN ALTURA MANOMETRICA Y BAJO CAUDAL. CON EL FIN DE EVITAR TURBULENCIAS POR RETORNO DEL FLUIDO, DEBIDO A LA BAJA VELOCIDAD DE SALIDA (V5), LA LONGITUD DE LA LUMBRERA DE SALIDA ES DE MU/4R. LAS PAREDES DEL TUBO DE SALIDA (3) DIVERGEN A PARTIR DE LA LUMBRERA DE SALIDA. LA PARED EXTERIOR (7) DEL TUBO DE SALIDA ARRANCA BAJO UN ANGULO DE 45G, Y CONSISTE EN UN ARCO DE CENTRO LA UNION DE LA PARED OPUESTA (8) CON EL ALOJAMIENTO (5).
