Abstract

UN SISTEMA DE EXTINCION DE INCENDIOS EN EL QUE SE INTRODUCE UN AGENTE QUIMICO LIQUIDO FORMADOR DE ESPUMA EN EL CHORRO DE AGUA Y EN CANTIDADES DIFERENTES PARA ASI MANTENER UNA MEZCLA CON UN PORCENTAJE PREDETERMINADO INDEPENDIENTEMENTE DE LAS VARIACIONES QUE TENGAN LUGAR EN LA CORRIENTE DE AGUA Y QUE UNA BOMBA ACCIONADA POR UN MOTOR DONDE UN PRIMER MARGEN DE VELOCIDAD DEL MOTOR QUEDA CONTROLADO POR UNA DURACION DE IMPULSOS QUE MODULA EL ACCIONAMIENTO AL MOTOR Y UN SEGUNDO MARGEN DE VELOCIDAD, QUE PRODUCE UN MOVIMIENTO INTERMITENTE, QUEDA CONTROLADO POR UNA DURACION DE RAFAGA QUE MODULA LA SEÑAL DE ACCIONAMIENTO CUANDO FUNCIONA A SU CICLO DE TRABAJO MINIMO MODULADO EN CUANTO A LA DURACION DE IMPULSOS. MEDIANTE LA UTILIZACION DE ESTA TECNICA, EL MARGEN DE VELOCIDADES DISPONIBLES DEL MOTOR ES MUCHO MAYOR QUE EL QUE SE ALCANZA MEDIANTE LA UTILIZACION DE UNA MODULACION DE DURACION DE IMPULSOS DE SOLO LA SEÑAL ACCIONADORA DEL MOTOR.
