🔍 Key Concepts

• Function of a shaft sleeve in a centrifugal pump (what it protects, and where it is located relative to the packing) • How packing contacts the shaft/sleeve and what happens if the contact surface is rough or grooved • Difference between problems caused at the packing area versus problems deeper inside the pump (casing, interstage seals, vibration)

💭 Think About

• Where does the shaft sleeve actually sit in relation to the stuffing box and packing, and what is its main job? • If the sleeve surface becomes badly worn, which nearby component is most likely to be affected directly by that worn surface? • Which options describe effects that are more likely to come from issues with alignment, bearings, or internal clearances rather than just sleeve wear at the packing area?

✅ Before You Answer

• Identify which choice refers to something in direct contact with the shaft sleeve surface during normal operation. • Eliminate any options that mainly involve rotor balance, bearings, or internal casing clearances, since those are less directly related to sleeve wear at the packing area. • Confirm that the consequence you pick would occur immediately when new packing is installed against a badly worn sleeve.
