Abstract

DISPOSITIVO AMORTIGUADOR PARA SUSPENSIONES DE PASTA UTILIZADOS EN LA FABRICACION DE PAPEL. FORMADO POR UN SENSOR (40) SITUADO CORRIENTE ARRIBA DEL AMORTIGUADOR, QUE PRODUCE UNA SEÑAL A TRAVES DE UN TRANSDUCTOR DE PRESION Y UN AMPLIFICADOR DE CONTROL (41). DICHA SEÑAL ES ALIMENTADA A TRAVES DE UN FILTRO DE PASO ALTO (42) DE FORMA QUE SOLO SE VEA AFECTADA POR CAMBIOS DE PRESION DE LA PASTA. PRESENTA MEDIOS DE DETECCION DEL NIVEL DE PASTA, CON EL FIN DE MANTENER CONSTANTE EL NIVEL, ACTUANDO SOBRE UNA VALVULA DE REBOSE (48).
