How many main bearings does the lube and scavenging pump supply oil to?

• A. 5 main bearings
• B. 6 main bearings
• C. 7 main bearings
• D. 8 main bearings

Answer: (C)

The lube and scavenging pump in a gas turbine system is designed to supply oil to various components, including the main bearings. In the case of typical gas turbine designs, the lube and scavenging pump generally provides oil to seven main bearings. This configuration ensures that all necessary areas are well-lubricated to maintain efficient operation and reduce wear on the engine components. Each main bearing plays a crucial role in supporting the engine shaft and maintaining proper alignment, making adequate lubrication essential for reliability and performance. The correct understanding of the number of bearings serviced by the pump is important for both maintenance and operational knowledge in gas turbine systems.
