Abstract

APARATO Y METODO PARA LA INSPECCION ULTRASONICA Y POR CORRIENTES PARASITAS, A DISTANCIA, DE ANILLOS DE RETENCION DE GENERADORES DE TURBINA. EL SISTEMA SE CARACTERIZA POR UN DISPOSITIVO DE EXPLORACION DE PEQUEÑO HUELGO QUE ALIMENTA SIMULTANEAMENTE PERCEPTORES DE ENSAYOS ULTRASONICOS Y DE CORRIENTES PARASITAS PARA REALIZAR LA INSPECCION DEL ANILLO DE RETENCION. EL DISPOSITIVO DE EXPLORACION ES CONTROLADO POR UNA UNIDAD BASADA EN UNA COMPUTADORA Y TIENE CODIFICADORES DE POSICION PARA SITUAR DE MANERA PRECISA LOS PERCEPTORES EN EL ANILLO DE RETENCION. EL DISPOSITIVO DE EXPLORACION PUEDE SER HECHO GIRAR EN TORNO A TODA LA CIRCUNFERENCIA DEL ANILLO DE RETENCION, ASI COMO PUEDE SER DESPLAZADO LINEALMENTE A LO LARGO DE SU LONGITUD AXIAL PARA REALIZAR LA INSPECCION EN UNA PASADA. FUNCIONES DE PRESENTACION Y DE ADQUISICION DE DATOS ESPECIALES PERMITEN LA RECOGIDA DE DATOS AUTOMATIZADA Y UN DISPOSITIVO DE PRESENTACION OFRECE LA INFORMACION OBTENIDA DE LOS PERCEPTORES.
