El Niño & Tribology: Changing Operating Conditions, Greater Focus on Reliability
El Niño can influence regional temperature and rainfall patterns, creating changing operating conditions that may present new challenges for lubrication, contamination control and equipment reliability.
For industries operating across Southern Africa, these conditions can have important tribological implications:
• Elevated temperatures can reduce lubricant viscosity and accelerate oxidation, potentially affecting lubricant film strength and service life.
• Drier and dustier conditions can increase airborne contamination, contributing to abrasive wear, filter loading and lubricant degradation.
• Rainfall variability and water ingress can introduce moisture into oils and greases, increasing the risk of corrosion and reduced lubrication effectiveness.
• Humidity and condensation can contribute to water contamination, corrosion and changes in lubricant performance.
For mining, agriculture, construction, manufacturing and transport, changing operating conditions reinforce the importance of correct lubricant selection, contamination control, condition monitoring and effective lubrication management.
Good tribology means understanding not only the machine and lubricant but also the environment in which they operate.
