Abstract

La presente invención se refiere a mejoras en máquina centrífuga con difusor de anchura variable, del tipo que comprende una carcasa y un impulsor montado de manera que pueda girar dentro de ella, para llevar un fluido de trabajo desde la entrada hasta la embocadura de un difusor anular dispuesto radialmente; que comprende un difusor de anchura variable conjuntamente con paletas guía de difusor fijas, las cuales están firmemente sujetas, mediante soldadura, caracterizadas porque dicho difusor comprende una pared fija dispuesta radialmente, y otra pared móvil, dispuesta de modo similar, adyacente a la primera, a fin de variar el tamaño del paso de difusir, un accionador conectado operativamente a la pared móvil para seleccionar la posición de la pared móvil con respecto a la pared fija, entre una posición de flujo máximo y una posición de flujo mínimo, dicha pared móvil tiene una serie de paletas difusoras las cuales pueden ser de forma aerodinámica alojadas de manera deslizable dentro de aberturas complementarias formadas en ella, dichas paletas pasan a través de la citada pared móvil y descansan contra la pared fija, de modo que las paletas cubren la distancia del paso difusor y un resorte de empuje actuando contra la pared posterior de cada paleta para obligar a ésta a tener contacto ajustado con la pared fija, de manera que la paleta resulta auto-ajustable en el conjunto.
