Abstract
Este documento se presenta una revisión a la estrategia de mantenimiento en las salas que conforman sistema de bombeo de aguas clarificadas recuperadas a partir del proceso de espesamiento de relaves en la Planta Concentradora de la División El Teniente de Codelco, y una propuesta de mejora para garantizar la continuidad de marcha de los procesos de molienda y flotación.
La revisión a la estrategia de mantenimiento consistió en ejecutar un levantamiento de la información disponible respecto a las fallas generadas y registradas en las salas de bombeo durante el periodo septiembre 2016 – septiembre 2017.
A partir esa información, se realizó un análisis de criticidad para los componentes de los equipos. Junto con esto, se presentan los lineamientos de la estrategia actual de mantenimiento llevada a cabo en el área.
Posteriormente, también a través de un análisis de criticidad se establecieron los principales modos de fallas para cada uno de los eventos registrados en las salas de bombas. Como resultado de este proceso, se elaboró una propuesta de mejoramiento del plan de mantenimiento de las salas de bombeo de aguas recuperadas que incluye actividades, pautas de trabajo, y el listado de repuestos de las bombas analizadas.
Se determinó que la implementación de la estrategia de mantenimiento predictivo o de monitoreo de condiciones requiere amplio control de parámetros de rendimiento y/o condición de los equipos de bombeo. Para esto, se requiere del aumento de cantidad mediciones y parámetros a controlar, lo que manifiesta la necesidad de adquisición de equipos de medición y la incorporación de actividades de análisis predictivo lubricante.
También se hizo evidente la existencia de diferencias entre las condiciones de diseño y las condiciones actuales de operación de las salas de bombeo, esto justifica la necesidad de controlar la calidad del fluido proveniente del “overflow” de los espesadores (agua clarificada).
This document presents a review of the maintenance strategy in the rooms that make up the clarified water pumping system recovered from the tailing thickening process in the Concentrator Plant of Codelco's El Teniente Division, and an improvement proposal to guarantee the continuity of the process of grinding and flotation. The revision to the maintenance strategy consisted of executing a survey of the available information regarding the failures generated and registered in the pumping rooms during the period September 2016 - September 2017. Based on this information, a criticality analysis was performed for the components of the equipment. Along with this, the guidelines of the current maintenance strategy carried out in the area are presented. Subsequently, also through a criticality analysis, the main failure modes were established for each of the events recorded in the pump rooms. As a result of this process, a proposal was made to improve the maintenance plan of the reclaimed water pumping rooms that includes activities, work guidelines, and the list of spare parts of the pumps analyzed. It was determined that the implementation of the strategy of predictive maintenance or monitoring of conditions requires ample control of performance parameters and / or condition of the pumping equipment. For this, it is necessary to increase the quantity of measurements and parameters to be controlled, which indicates the need for the acquisition of measuring equipment and the incorporation of predictive lubricant analysis activities. It also became evident the existence of differences between the design conditions and the current operating conditions of the pumping rooms; this justifies the need to control the quality of the fluid coming from the “overflow” of thickeners (clarified water).
