Question 1 of 27070

When starting a turbo generator in an automated plant, you must provide lube oil pressure to the unit by means of a/an __________.

🔍 Key Concepts

• Pre-lubrication requirements for high-speed rotating machinery like turbo generators • How lube oil pressure is normally supplied before the shaft is turning • Difference between driven pumps (shaft/main pump) and independent/auxiliary pumps

💭 Think About

• Ask yourself: when the turbo generator is still stopped, which option can actually build oil pressure without the turbine/generator shaft turning? • Which option is specifically installed to protect bearings during startup and shutdown when normal running pumps may not yet be effective? • Consider which source of oil pressure would be the most reliable and independent in a fully automated plant start sequence.

✅ Before You Answer

• Verify which pumps are shaft-driven and which can run independently of shaft rotation. • Check which option is commonly called a pre-lube or starting pump in machinery diagrams and training manuals. • Confirm which choices would not reliably give pressure if the other machinery or gravity head is unavailable or insufficient.
