What is Condition Monitoring?
Condition monitoring is the process of determining the equipment fitness, by monitoring critical parameters (eg. temperature, pressure, vibration). Abnormalities observed are indicative of developing problems that can lead to potential failure. Proactive condition monitoring helps in identifying failures at the initial stage, before they develop into major breakdowns, thus avoiding downtime and its consequences.
Condition monitoring is effectively used in equipment with moving or rotating parts (eg. pumps, motors), whereas techniques like non-destructive testing are used in stationary equipment (eg. boilers, storage tanks). Condition monitoring techniques can also be applied to the production output to determine flaws in the manufacturing process. Ultrasound testing can detect variations in material thickness or flaws beneath the surface.
Condition monitoring can be discrete or done over specific time intervals or monitored continuously over time. It can give near real-time status, operating condition or position of the underlying equipment and often can give warning symptoms of imminent breakdown.
Values of the parameter captured can be compared against equipment standards or plotted as a performance trend over time or compared to the performance of a similar class of equipment. Deviations detected trigger further actions including alerts and notifications and generation of preventive maintenance work orders.
Benefits of Condition Monitoring
1.Monitoring: Monitoring and evaluation are essential to maintain the equipment condition under control and to determine the nature of intervention to avoid failures.
2.Diagnostics: Comprehensive information on equipment condition and behavior to troubleshoot and analyze the root cause quickly and efficiently for prompt resolution.
3.Prognostics: First Symptom alerts generation, much before the occurrence of catastrophic failure to define preventive maintenance programs.
4.Reliability: Increase reliability of the system through multi-dimensional analysis and probabilistic models.
5.Better Return on Assets: Condition monitoring prevents catastrophic failures, thereby improving equipment uptime and operations. Preventive maintenance programs ensure increased asset life and better utilization.
Condition Monitoring Techniques
Condition monitoring finds many applications in managing industrial assets. Frequent condition monitoring techniques include:
How to do Condition Monitoring?
Condition monitoring implementation should flow from enterprise maintenance strategy. Condition monitoring system for an equipment is determined based on multiple factors including equipment criticality, operating condition, risk levels, the impact of a breach to people, assets and environment, etc. Based on the goals, a set of parameters that mirror the equipment condition and the frequency of monitoring are determined. Often there can be multiple independent sets of such parameters to monitor different aspects of condition and behavior.
Implementing condition monitoring requires specialized knowledge on five key aspects:
Analysing the condition monitoring signals and interpreting inferences requires deep domain expertise and specialized skills and training. For the same equipment, condition monitoring of lubricant analysis and vibration acoustics require diverse skills and knowledge.
Role of CMMS in Condition Monitoring
Manual interventions required for condition monitoring restricted its frequency and application in the past and were often restricted to tracking very few critical parameters. The proliferation of built-in processors and control systems in modern equipment makes available enormous data today. The data explosion has resulted in a paradigm shift in the usage of data, from complete consumption to exception handling. Volume, variety, and velocity of data has made manual analysis inadequate and enforced automated processing.
Computerized Maintenance Management Systems (CMMS) hosts all the condition monitoring information that gets captured by different independent systems. Modern CMMS comes with a powerful rules engine that can validate these parameters against set rules. Advanced analytical tools can provide statistical data analysis, what-if scenarios, and visual representations. System modeling of the underlying equipment, multi-factor analysis and simulation can portray equipment behavior under adverse operating conditions to improve equipment reliability and execute predictive maintenance.
