Main steam turbine lubricating oil systems...

🔍 Key Concepts

• Main steam turbine lube oil systems must run continuously without shutdown for cleaning filters/strainers • Types of contaminants expected in lubricating oil (metal particles, sludge, dirt) and how they’re best removed • Common marine engineering term for a duplex, basket-type strainer used on large oil systems

💭 Think About

• Think about which type of strainer is practical for a high‑flow, continuous‑duty lubricating oil system on a turbine • Ask yourself which option is most closely associated with large marine lube oil systems, not small fuel tanks or specialty uses • Consider which option’s name you’ve seen in connection with duplex or basket strainers that can be cleaned while the system stays in service

✅ Before You Answer

• Eliminate any type of strainer you usually find on small tanks or suction inlets, rather than on main lube oil headers • Ask: can this strainer type be arranged in duplex form so one side can be cleaned while the other is online? • Recall which of these is a standard marine engineering exam term for the main lubricating oil strainers on turbines and main engines
