Abstract
LA INVENCION SE REFIERE A UN DISPOSITIVO DE TRANSPORTE INYECTOR PARA TRANSPORTE NEUMATICO DE POLVO, EN PARTICULAR MATERIALES DE RECUBRIMIENTO PULVERIFORMES. PARA LA MEDICION DE LA CANTIDAD DE POLVO TRANSPORTADA SE MIDE EL VACIO GENERADO EN UN INYECTOR (4) DE MANERA INDIRECTA DE TAL MODO, QUE SE MIDE LA CANTIDAD DE CORRIENTE CON RESPECTO A LA CORRIENTE DE AIRE O LA CAIDA DE PRESION EN UN CANAL (30) DE MEDICION ESTRANGULADO, QUE UNE LA ATMOSFERA (32) EXTERIOR CON LA CAMARA (10) DE DEPRESION DEL INYECTOR (4) DE FORMA REGULAR A LA CORRIENTE. PARA EVITAR ERRORES DE MEDICION DEBIDO A OSCILACIONES DE PRESION EN UN CANAL (8) DE ASPIRACION DE POLVO SE HA PREVISTO UNA ENTRADA (56) DE AIRE DE COMPENSACION, A TRAVES DE LA CUAL SE APLICA UNA CANTIDAD REDUCIDA DE AIRE DE COMPENSACION EN EL CANAL (8) DE ASPIRACION DE POLVO, PARA HACER MAS PEQUEÑAS LAS OSCILACIONES DE PRESION QUE APARECEN CON ALTA FRECUENCIA Y CON RESPECTO A LA AMPLITUDES DE OSCILACION.
