Abstract

SISTEMA DISPENSADOR DE ESPUMA QUE DISPONE DE UN CONTROL QUE MIDE LA CANTIDAD DE MATERIAL LIQUIDO DE ALTA VISCOSIDAD QUE SE REPARTE EN UN MEZCLADOR, DETERMINA LA CANTIDAD DE GAS A PRESION QUE SE HA DE INYECTAR EN EL MEZCLADOR PARA PRODUCIR UN MATERIAL ESPUMOSO CON LA CONCENTRACION DESEADA DE GAS, MIDE LA CANTIDAD REAL DE GAS QUE SE REPARTE EN EL MEZCLADOR , Y GENERA UNA SEÑAL DE ERROR ACUMULATIVO QUE REPRESENTA LA DIFERENCIA ENTRE LA CANTIDAD DE GAS Y EL GAS QUE HA SIDO REALMENTE REPARTIDO. SE GENERA UNA SEÑAL DE CONTROL PARA REGULAR EL FLUJO DE GAS AL MEZCLADOR EN RELACION CON LA MAGNITUD DE LA SEÑAL DE ERROR. UN METRO DE FLUJO DIGITAL GENERA UNA PULSACION POR CADA AUMENTO EN LA CANTIDAD DE MATERIAL LIQUIDO ENVIADO AL MEZCLADOR DURANTE UN INTERVALO DE TIEMPO. EN CADA INTERVALO SUCESIVO, SE CUENTAN LAS PULSACIONES Y EL RESULTADO ES MULTIPLICADO POR UNA PROPORCION GAS-MATERIAL PREFIJADA, DE LA CUAL SE SUSTRAE EL FLUJO DE GAS MEDIDO Y SE AÑADE LA DIFERENCIA AL PERIODO DE ERROR ACUMULATIVO. ELPERIODO DE ERROR SE COMBINA CON UN PERIODO PROPORCIONAL A LA CANTIDAD DE MATERIAL LIQUIDO ENVIADO SOBRE UN NUMERO PREDETERMINADO DE INTERVALOS SUCESIVOS DE TIEMPO PARA PRODUCIR LA SEÑAL DE CONTROL.
