🔍 Key Concepts

• Gland sealing system on a marine steam turbine – what it is trying to keep constant when power changes • How the regulator senses pressure (look at the bellows, float, or diaphragm in K/L) versus how it controls flow (pilot valve, main valve, needle valve) • Direction of movement of links and levers when gland pressure falls or rises as the engine comes up to full ahead

💭 Think About

• When you go from dead slow to full ahead, does gland leakage steam pressure at the turbine glands initially tend to increase or decrease? Which part of the regulator would feel that change first? • Trace the motion from the sensing element (K/L side) through the linkage to the pilot valve area (E/J). Which part must move before any other listed components can respond? • Look at which component is purely an adjustment or throttling device (set by hand and then left alone) versus which parts move automatically with load changes. Which of the options describes that first automatic motion?

✅ Before You Answer

• Identify which part in the illustration is the pressure-sensing element (follow the arrows I and J and the chamber K/L). • Verify which part is the pilot valve or pilot bushing that actually ports steam to move the main valve – this cannot move until the sensing linkage moves. • Confirm whether the needle valve in the drawing is manually set or automatically positioned; make sure you don’t pick an option that describes a normal hand setting instead of an automatic first response.
