Question 1 of 27070

Labyrinth packing rings are installed on turbine diaphragms to minimize __________.

🔍 Key Concepts

• Function of labyrinth packing in steam turbines • The role of diaphragms and interstage spaces in a multi-stage turbine • Difference between internal leakage and external leakage to atmosphere

💭 Think About

• Think about where the labyrinth packing rings are physically located on the turbine diaphragm and what flow path they are trying to block. • Ask yourself: is the primary concern keeping steam inside the casing, or controlling how steam moves between stages along the rotor? • Consider which option best matches the idea of reducing losses between turbine stages rather than sealing the entire casing from outside air.

✅ Before You Answer

• Verify what a diaphragm does in a multi‑stage turbine (nozzles and separation between pressure stages). • Confirm where labyrinth seals are commonly placed: along the shaft/rotor path or on the outer casing? • Make sure the option you choose deals with internal stage-to-stage efficiency losses, not general casing or atmospheric leakage.
