Q

Additives commonly found in turbine lubricating oil include __________.

🔍 Key Concepts

• Function of turbine lubricating oil in high-speed, high-temperature rotating machinery • Typical additive packages used in lubricating oils (foam control, oxidation control, wear protection) • Difference between turbine oils and heavy-duty gear oils or engine oils

💭 Think About

• Think about what problems can occur in a fast-rotating turbine oil system (involving reservoirs, pumps, and bearings) and what additives would prevent those problems. • Which of the listed additives are commonly needed in systems with large oil sumps and high circulation rates? • Are all of these additives equally critical for lightly loaded, high-speed turbine bearings, or is one of them more associated with heavily loaded gear teeth and boundary lubrication?

✅ Before You Answer

• Identify which additives are essential for preventing oxidation and sludge formation in hot, circulating oil systems. • Decide which additives are important for controlling foam and air entrainment in large oil reservoirs. • Consider whether extreme pressure (EP) additives are typical for turbine oils, or more commonly associated with gears operating under very high tooth loads.
