Abstract

Un método para mejorar los datos de bomba acústica para monitorear la condición de bomba en operación. El mejoramiento puede estar en la forma de una reducción sustancial en la cantidad de datos que van a ser procesados por el firmware hasta un nivel mucho más manejable. Esto se puede lograr a través de pre-filtración de los datos acústicos adquiridos, cálculo de los momentos de frecuencia, y por medio de aplicación de un filtro medio a los datos acústicos; A pesar de todo, se puede emplear una técnica de binarización que utilice un vector de características que incluye aunque no se limita a umbral doble derivado a partir de estadísticas amplitudes mejoradas, por lo cual los datos acústicos mejorados son resumidos a una serie de eventos acústicos potenciales de anchuras particulares. Estas anchuras pueden representar una duración de cada evento acústico y pueden ser verificadas para correlación con la velocidad de la velocidad de operación de la bomba. Los eventos acústicos que se correlacionan con una velocidad de operación de la bomba pueden representar una condición de falla de la bomba como en el caso cuando la anchura es aproximadamente de la duración de la mitad de un ciclo de la bomba y una válvula de bomba con fuga se presenta para el mismo período.
