🔍 Key Concepts

• Main turbine bearing lubrication requirements and what happens if lubrication is lost, even briefly • The difference between reducing speed and performing an immediate emergency stop in terms of bearing protection • Purpose and limitations of emergency/hand lube oil pumps and gravity tanks in a turbine lube oil system

💭 Think About

• Ask yourself: If lube oil pressure is at ZERO at the main bearing, how long can you safely keep the turbine turning before damage begins? • Which action actually guarantees that metal-to-metal contact in the bearings is stopped as fast as possible? • Do any of the options assume that lube oil level or supply can recover while the turbine is still rotating with no pressure?

✅ Before You Answer

• Verify what zero lube oil pressure at main bearings implies for immediate risk of seizure and damage • Check which choice removes or minimizes shaft rotation the fastest versus which ones try to ‘fix’ the oil system while still running • Confirm whether hand pumps or gravity tanks can instantly provide enough pressure/flow at full or reduced load to protect heavily loaded turbine bearings
