Abstract

EL DISPOSITIVO PARA EL PRONOSTICO DE SACUDIDAS O IMPULSOS PARA UN COMPRESOR CENTRIFUGO (100), TIENE UN DETECTOR DIFERENCIAL DE PRESION (13) Y UN CONTROLADOR (14). EL DETECTOR (13), DETECTA LA PRESION DIFERENCIAL ENTRE LA PRESION LATERAL DE LA CAMPANA AL LADO DE LA ENTRADA DE UN DIFUSOR (4) EN EL COMPRESOR CENTRIFUGO (100) Y UNA PRESION DEL REFUERZO LATERAL AL LADO DE LA ENTRADA DEL DIFUSOR (4). EL CONTROLADOR (14) COMPARA LA PRESION DIFERENCIAL DETECTADA DESDE EL DETECTOR (13) CON UNA PRESION DIFERENCIAL ESTABLECIDA DE ANTEMANO PARA QUE SEA MAS BAJA QUE LA PRESION DE IMPULSION DIFERENCIAL, ENTRE LA PRESION LATERAL DE LA CAMPANA Y LA DEL REFUERZO LATERAL, EN UN TIEMPO DE IMPULSION, Y HACE SALIR UNA SEÑAL DE IMPULSION QUE PREDICE LA CENTRIFUGACION, CUANDO LA PRESION DIFERENCIAL DETECTADA ES MAYOR QUE LA PRESION DIFERENCIAL ESTABLECIDA.
