Specialized articles on root cause analysis: failure investigation and prevention strategies.
The overheating of an SKF FY20TF servo motor was analyzed to identify the root causes. Sizing errors, poor duty cycle estimation and cooling system failure…
An increase in temperature, abnormal vibrations and chain elongation indicate a critical failure. Root cause analysis shows that insufficient maintenance is the main cause. Replacing…
Pump cavitation leads to reduced efficiency, vibration, and mechanical failure. This article investigates NPSH analysis, root causes, and diagnostic vibration signatures for the Siemens 6SN1123-1AA00-0CA2…
The Siemens thermal relay 6ES7 361-3CA01-0AA0 may experience false trips due to ambient temperature, load profile, or design errors. A rigorous analysis and corrective actions…
Shaft key failure in FIBRO 2480.21.00150.063 couplings is often due to design stress mismatch, improper fit tolerance, or fatigue. This analysis provides a practical checklist…
Introduction The burning of a solenoid valve coil is a common problem in industrial automation systems, especially in environments with high operating loads and elevated…
A DANFOSS OMP1001510622 bearing failed prematurely after 14 000 hours. The analysis identifies causes such as improper mounting and contamination. Corrective measures and rigorous follow-up…
The seal failure of the hydraulic cylinder Allen Bradley 1492-AIFM8-3 is caused by contamination, mechanical misalignment or pressure spikes. The analysis revealed signs of particulate…
A forensic engineering investigation into a catastrophic shaft key failure, analyzing design stress, fit tolerances, and cyclic fatigue under heavy industrial loads.
Uneven wear patterns on the REXROTH DBDH6G10/50 show contamination, pre-compression and lubrication gaps. The causes are systematically analyzed and answered with specific measures for prevention.…
Forensic analysis of a chain drive with premature elongation and sprocket wear. Root causes, measurements according to UNE/EN standards, and a corrective action plan are…
Thermal relay nuisance tripping in industrial motor systems is often caused by ambient temperature, load profile, or incorrect relay sizing. This article presents a forensic…
