Abstract

SE PROPONE UNA COMBINACION DE UNA ROSCA DE EXTRUSION DE ACTUACION SUAVE Y UNA BOMBA DE FUERZA DEL TIPO DE MULTIPLICACION HACIA ABAJO DEL MISMO, PARA OBTENER EL AJUSTE DE LA TEMPERATURA DE UN MATERIAL SINTETICO PLASTIFICADO CON LA MENOR INERCIA POSIBLE, Y UN RENDIMIENTO TOTAL CONSTANTE SIMULTANEO. LAS VELOCIDADES DE ROTACION DE LA ROSCA DE EXTRUSION Y LA BOMBA SE PUEDEN AJUSTAR INDEPENDIENTEMENTE. DEBIDO A SU CARACTERISTICA DE SUAVE TRANSPORTE, EL EFECTO DE TRANSPORTE Y POR LO TANTO LA CONVERSION DE POTENCIA ESPECIFICA DE LA ROSCA DEPENDE MUCHO DE LA VELOCIDAD DE TRANSPORTE. POR LO TANTO, EL CICLO DE PRESION DE LA ROSCA A TRAVES DE LA ESCALA DE REVOLUCION COMPLETA SE MANTIENE A UN BAJO NIVEL, POR DEBAJO DEL MAXIMO PERMITIDO DE LA PRESION DE LA BOMBA. LA TEMPERATURA DEL COMPUESTO EN LA SALIDA DE LA ROSCA SIGUE POR LO TANTO LA VELOCIDAD DE ROTACION Y SE UTILIZA EL AJUSTE DE LA VELOCIDAD PARA REGULAR LA TEMPERATURA. EL RENDIMIENTO TOTAL ESTA GOBERNADO POR LA VELOCIDAD DE ROTACION DE LA BOMBA DEFUERZA DE MANERA QUE SU PARAMETRO DE OPERACION SE PUEDA CONTROLAR AJUSTANDO LA VELOCIDAD DE LA BOMBA. UN SISTEMA DE COMPENSACION DE DESLIZAMIENTO/DENSIDAD PREVIENE CUALQUIER INESTABILIDAD DE RENDIMIENTO TOTAL CAMBIANDO LA TEMPERATURA DEL COMPUESTO.
