Question 1 of 27070

Before starting a reciprocating, steam-driven pump that has been idle for a period of time, you should __________.

🔍 Key Concepts

• Condensate buildup in a steam cylinder when equipment has been idle • Purpose of cylinder drain cocks on steam-driven machinery • Risks of water hammer or hydraulic lock when admitting steam to a cold, idle cylinder

💭 Think About

• What happens inside the steam cylinder while the pump is shut down and cooling, and what fluid is likely to collect there? • Before you admit high-pressure steam to a cold cylinder, what must you do to protect the cylinder and prevent damage? • Which option directly addresses the condition inside the steam cylinder after a long idle period?

✅ Before You Answer

• Identify which choices deal with the steam side versus the liquid (pumpage) side. • Ask which action specifically removes condensate from the steam cylinder before steam is admitted. • Eliminate any option that would trap condensate in the steam cylinder at the moment of startup.
