What should you do when a turbine bearing shows signs of overheating?

Question 1 of 27070

What should you do when a turbine bearing shows signs of overheating?

🔍 Key Concepts

• Bearing overheating and risk of rapid damage or seizure • Effect of load/speed on bearing temperature • Why simply changing oil pressure or cooling water might not fix the root problem

💭 Think About

• Which action most quickly reduces the mechanical load and friction on the bearing itself? • Could increasing pressure or extra cooling hide a serious problem instead of protecting the machinery? • What is the safest immediate response that buys you time to investigate without risking a bearing wipe or seizure?

✅ Before You Answer

• Verify which choice directly reduces load and friction on the bearing right away • Check if any option might delay or mask the problem instead of addressing it • Think about standard engineering practice for overheating rotating machinery bearings in turbine plants

Stop the turbine

Increase the lube oil pump discharge pressure

Immediately reduce speed

Increase the cooling water supply to the lube oil cooler
