A vibration alarm during a turnaround week rarely arrives at a convenient time. On a 1,500 kW induced-draft fan, the alert traced back to BPFO harmonics that had climbed over…
Learn More →Failure Modes Effects and Criticality Analysis
A centrifugal pump has failed three bearings in eighteen months. The maintenance team has performed the same scheduled lubrication and inspection routine each time, yet the breakdown pattern hasn't changed.…
Learn More →Gearbox Failure Modes: Diagnosis and Prevention Guide
Bearings account for about 70% of gearbox failures, while gears account for about 26%, according to a large NREL dataset built from 257 damaged records. The most common failure mode…
Learn More →Vibration Analysis of Machines: A Practical Reliability
A route technician finds a sharp vibration increase on a large induced-draft fan during a Tuesday morning walk-down. The work order is raised, the bearing is replaced during a planned…
Learn More →Baseline Data Collection for Predictive Maintenance
A maintenance manager reviews a vibration trend and sees a clean, stable line. The baseline looks convincing, so alarm limits are approved and the route is released. Weeks later, the…
Learn More →What Is Predictive Maintenance and How Does It Work
A Sunday-night shift at a chemical plant turns urgent when a 750-kW motor driving a centrifugal pump seizes. The motor's inboard bearing has been spalling for weeks, but the defect…
Learn More →What Is Condition Monitoring? a Practical Guide
Condition monitoring is the practice of measuring equipment parameters such as vibration, oil condition, temperature, and motor current to detect degradation before failure, enabling maintenance teams to intervene based on…
