Abstract

LA CANTIDAD DE PASO DE CADA CANTIDAD CONDUCIDA DE UN DEPOSITO DE COJINETE (1 - 4) POR UN DISPOSITIVO TRANSPORTADOR (5 - 8) SE MIDE POR UN MEDIDOR DE PASO (10). LA CANTIDAD DE PASO SE REGULA POR UN REGULADOR (9). MIENTRAS EL VALOR REAL DE LAS CANTIDADES DE PASO DE CADA COMPONENETE INDIVIDUAL NO CORRESPONDA AL VALOR TEORICO, SE LLEVAN CORRIENTES DE CANTIDADES DE RECOLECCION POR LA VALVULA DE CONEXION (11) Y LA CONDUCCION DE RETROCESO (12) AL DEPOSITO DE COJINETE (1 - 4) RESPECTIVO. CUANDO EL VALOR REAL COLECTADO CORRESPONDE AL VALOR TEORICO, SE CONECTA LA VALVULA DE CONEXION (11) DE MODO QUE LOS COMPONENTES INDIVIDUALES SE LLEVAN POR LA CONDUCCION DE ALIMENTACION (14) AL MEZCLADOR (13). LA MEZCLA ENGENDRADA SE ANALIZA EN DISPOSITIVOS DE MEDICION (18 - 20). CUANDO EL VALOR REAL ANALIZADO DE NUEVO NO CORRESPONDE AL VALOR TEORICO DE ANALISIS, SE PRODUCE DE NUEVO UNA CONEXION INMEDIATA DE LAA VALVULA DDE CONEXION (11) EN EL MECANISMO DE CONDUCCION DE RETROCESO. ASI NO ES NECESARIO DURANTE EL LAPSO DE TIEMPO MIENTRAS SE ESTABILIZA EL CIRCUITO DE REGULACION, DESPEJAR UNA MEZCLA AUN NO ELABORADA, ES DECIR, EL PRODUCTO COMO DESPERDICIO., CUANTAS MAS VECES VUELVAN A LLEVARSE LOS COMPONENETES INDIVIDUALES DE NUEVO AL TANQUE DE DEPOSITO (1 - 4), HASTA QUE NO PUEDA APARECER NINGUNA PERDIDA DE PRODUCTO Y SE ALCANCE UN ELEVADO STANDAR DE CALIDAD DEL PRODUCTO.
