🔍 Key Concepts

• Centrifugal feed pump start-up sequence and why you need liquid at the eye of the impeller before starting • Safe practices for venting and draining steam lines to a turbine before opening up to full pressure • What happens if a turbine or pump is started with no suction, air-bound casing, or water-hammer risk

💭 Think About

• Think through what a feed pump actually needs in place (on the water side) before you ever spin it with the turbine—what must be open or filled? • Consider which valves (vents, drains, exhaust) are typically opened during warm-up and why suddenly trapping steam or condensate can be dangerous. • Ask yourself: in normal shipboard procedures, which item in the choices would almost always be explicitly stated in the checklist as a first step on the pump side?

✅ Before You Answer

• Verify which side of the system each choice is dealing with: pump suction, pump casing vent, steam drains, or steam exhaust. • Check which actions would risk air-binding the pump, water hammer, or over-pressurizing part of the steam system. • Confirm which step is a standard, must-do action for almost any centrifugal pump prior to starting its driver.
