🔍 Key Concepts

• Turbine bearing high temperature alarms and what they indicate about bearing condition • Manufacturer’s immediate emergency actions versus follow‑up corrective actions • The relationship between turbine speed/load and bearing temperature

💭 Think About

• Ask yourself: when an alarm indicates a potentially serious bearing problem, is your first priority to protect the machinery, or to try to maintain power/output? • Which actions might actually increase friction, load, or risk of wiping the bearing before you’ve confirmed the cause of the high temperature? • Think about the sequence: what is the safest immediate action, and what kinds of adjustments (oil flow, cooling water, etc.) are usually considered after the situation is stabilized?

✅ Before You Answer

• Verify which option most directly reduces stress and possible damage to the bearing right away. • Check which actions could mask the symptom without removing the cause of overheating. • Confirm which response is most consistent with standard emergency operating procedures for rotating machinery when a bearing is suspected to be overheating.
