Question 1 of 27070

All of the following steps are taken in starting a centrifugal pump, EXCEPT to __________.

🔍 Key Concepts

• Centrifugal pump starting sequence and why sequence matters • Difference between actions done before starting vs. while running/under pressure • Purpose of a relief valve in a pump system

💭 Think About

• Think about which actions must be completed so the pump is full of liquid and not running dry before you start it. • Consider which item is normally adjusted or set when the system is designed or before operation, and not something you usually "do" every time you start the pump. • Ask yourself: which of these steps, if skipped during starting, would immediately risk damage to the pump (like loss of suction, air binding, or bearing damage)?

✅ Before You Answer

• Be clear on what "vent the pump casing" accomplishes in a centrifugal pump. • Recall why suction and discharge valves are positioned a certain way at startup to avoid overload or loss of prime. • Think about when a relief valve is normally set and by whom (operator vs. maintenance/engineering).
