The False Promise of Vibration Data as a Preventative Tool
In the world of industrial maintenance, vibration analytics has become synonymous with predictive maintenance. It’s a well-established technique that promises early detection of potential failures. But does it truly deliver on the promise of being preventative? Or is it more reactive than we’ve been led to believe?
Let’s challenge the narrative that vibration data alone can achieve preventative and predictive maintenance for pumps. While vibration monitoring undoubtedly plays a role in identifying issues, it often detects problems that have already begun to manifest. By the time a vibration alert is triggered, damage has often already started—making it a reactive tool rather than a purely preventative one.
Understanding the Limitations of Vibration Analytics
Vibration analytics excels at identifying early signs of component failure, particularly in bearings, couplings and other rotating parts. However, the key limitation is that vibration data usually signals that a failure process is already underway. By the time abnormal vibrations are detected, internal components may already be compromised.
Here are a few scenarios that highlight this limitation:
Bearing Fault Detection: Vibration analysis can pick up on changes in bearing condition, but these changes often occur after the bearing has already begun to degrade.
Seal Failures: Mechanical seals often fail due to improper flow conditions or dry-run situations. Vibration might detect a problem, but it won’t pinpoint the operational cause.
Multi-Pump Systems: In complex systems, vibration data might show imbalance issues between pumps, but it won’t tell you what operational changes triggered the imbalance.
The bottom line? Vibration analytics is valuable, but it’s not the silver bullet for preventative maintenance. It provides insights when failure is imminent, not before damage begins.
Why Reliabix Analytics Goes Beyond Vibration
At Reliabix Analytics, we believe that relying solely on vibration data is too late. Instead, we consider a holistic approach by analyzing all available data points to provide truly preventative insights. Our methodology focuses on identifying the operational behaviors and conditions that lead to failures—before they cause damage.
Here’s how we do it differently:
1. Identifying Early Warning Signs of Issues
We don’t wait for a component to show signs of wear. By analyzing a combination of flow, pressure, energy consumption, and other engineered metrics, we detect deviations from optimal operating conditions that can lead to damage. This proactive approach helps us address potential issues long before they escalate into failures.
For example, our analysis might reveal that a pump is operating outside its Best Efficiency Point (BEP) for extended periods—a key risk factor for bearing and seal failures. Addressing this operational inefficiency prevents damage from occurring in the first place.
2. Identifying Bad Actors Before They Cost You Money
By leveraging advanced analytics, Reliabix identifies “bad actors”—assets that are likely to cause reliability issues. This doesn’t just mean identifying a failing component; it means understanding which operational practices are contributing to those failures.
For instance, if a multi-pump system is experiencing frequent failures, we analyze the system’s behavior to uncover hidden imbalances or improper control settings that are causing unnecessary strain on specific pumps.
3. Driving Total Cost of Ownership Reduction
Our focus isn’t just on preventing failures; it’s about reducing the total cost of ownership for your assets. By optimizing operations and addressing inefficiencies, we help you achieve significant cost savings in maintenance, energy consumption, and unplanned downtime.
Take energy efficiency as an example: A pump operating at optimal flow conditions consumes less power, experiences less wear, and requires less maintenance. These improvements don’t just extend the life of the asset—they reduce your energy bills and improve your bottom line.
The Power of Comprehensive Analytics
Reliabix Analytics transforms hidden data into actionable insights that drive reliability and efficiency. Here’s what sets us apart:
Proactive Root Cause Analysis: We don’t just wait for a problem to occur—we identify the underlying causes of potential failures upfront.
Holistic Data Integration: We integrate multiple data sources, including operational data, maintenance history, and environmental factors, to provide a complete picture of asset health.
Customized Solutions: Our analytics are tailored to your specific operations, ensuring you get the most relevant and actionable insights.
The Bonus: Boosting Productivity and Energy Efficiency
By defining operational metrics holistically, our approach not only prevents damage, improving reliability, but also boosts productivity and energy efficiency. For example:
Reducing downtime means more productive hours.
Optimizing energy consumption for reliability leads to cost savings and a reduced carbon footprint.
The result? A more reliable, efficient, and profitable operation.
Conclusion: Don’t Settle for Reactive Maintenance
Vibration analytics has its place, but it’s not the ultimate solution for preventative maintenance. To achieve true reliability, you need a comprehensive approach that considers all available data. At Reliabix Analytics, we’re here to help you unlock hidden insights, prevent damage, and drive down your total cost of ownership.
Remember, preventative maintenance starts with understanding what causes damage—not just detecting it after it has started.
