Question 1 of 27070

In a pressure type main propulsion turbine lubrication system, the lube oil service pumps normally take suction from the main sump and discharge directly to the __________.

🔍 Key Concepts

• Normal flow path of oil in a pressure-type lube oil system for main turbines • Purpose and location of a lube oil header versus individual components like bearings or coolers • Difference between a supply manifold and the individual users (bearings, gears, etc.)

💭 Think About

• Think about whether the pump normally discharges to a single distribution point or directly to one specific component. • Consider where in the system you would most logically control pressure and distribute flow to multiple consumers. • Ask yourself: which component on the list would be the central point feeding many parts of the turbine, rather than just one or two pieces of equipment?

✅ Before You Answer

• Verify which item in the choices acts as a common supply line/manifold for the entire lubrication system. • Check your mental diagram: does oil usually go from the sump to the pump, then to cooling/filtration and distribution, and only then to bearings? • Confirm that the selected choice can realistically serve all bearings and gears simultaneously, not just one location.
