🔍 Key Concepts

• Centrifugal pump shaft sleeves and their purpose in protecting the shaft from wear and leakage • Common causes of scoring on a pump shaft sleeve (e.g., improper lubrication, foreign particles, mechanical misalignment) • Best-practice maintenance actions when damage or abnormal wear is discovered on rotating machinery components

💭 Think About

• If a protective sleeve on a rotating shaft shows localized scoring, what does that tell you about current operating conditions and future risk if left unchanged? • Which options focus on actually correcting the root cause of the damage versus only changing operating conditions? • When you see physical damage on a part that is designed to be replaceable, what is the usual maintenance philosophy: adjust operating parameters, re‑align, or repair/replace the damaged part after eliminating the cause?

✅ Before You Answer

• Identify which choice both eliminates the cause of the scoring and restores the integrity of the pump component. • Eliminate any option that ignores the existing damage and merely changes speed, lubrication flow, or alignment without dealing with the scored area itself. • Verify which answer reflects standard preventive maintenance practice for protective sleeves on centrifugal pump shafts, not for controlling system speed or flow.

Which of the following actions should be taken if, during a routine maintenance inspection of a centrifugal pump, localized scoring on a pump shaft sleeve is detected?

Correct the cause of the scoring and repair the sleeve or replace with a new one.

Reassemble the unit and provide more water leak off for proper lubrication.

Check for parallel alignment of the sleeve radial faces to the sleeve bores.

Reassemble the unit and adjust the governor to obtain a slower speed.
