    Study Notes

    • The text discusses a practical example of maintaining equipment in a water treatment plant, specifically the decantation process.
    • The process involves various systems: water residual pump, polymer pump, centrifuge for sludge, tornillo sin fin (gearbox), and automation system.
    • The text highlights the importance of maintaining accurate records of operational and inoperational hours for each system to assess performance and identify potential issues.
    • Analyzing the data, it is noted that there have been eight failures in the water residual pump, four in the polymer pump, one in the centrifuge, seven in the gearbox, and ten in the automation system.
    • The operational and inoperational hours are used to calculate key performance indicators such as Mean Time Between Failures (MTBF) and Mean Time to Recovery (MTTR).
    • For example, the water residual pump has a median time to failure of 62.5 hours, a mean time between failures of 84 hours, and a mean time to recovery of 21.5 hours.
    • Similar analyses are conducted for the other systems, and based on the findings, recommendations are made for preventative maintenance or potential system upgrades.
    • The text emphasizes the importance of understanding the unique characteristics of each system and the impact of system failures on overall plant performance.
    • Finally, the text encourages engineers to utilize key performance indicators to make informed decisions about maintenance strategies and optimize system availability.
