Question 1 of 27070

The purpose of wearing rings as found in large centrifugal pumps is to __________.

🔍 Key Concepts

• centrifugal pump construction – impeller, casing, and clearances • wear (wearing) rings on pumps vs. piston rings on engines • effects of erosion and leakage at the impeller/casing interface

💭 Think About

• Which pump parts actually touch or come very close to each other during normal operation, and what happens to those surfaces over time? • If one small, sacrificial part can be changed instead of the whole pump casing or impeller, which choice best matches that idea? • Do any of the options describe something that seems unrelated to how a centrifugal pump is built (e.g., explosions, alignment, or ‘watching it run’)?

✅ Before You Answer

• Identify where wearing rings are physically located on a centrifugal pump (impeller eye/casing interface). • Decide which option describes a part that is sacrificial and replaceable rather than a permanent structural part. • Eliminate any options that do not relate to erosion, clearance, or surface wear between rotating and stationary parts.

Question 1 of 27070

The purpose of wearing rings as found in large centrifugal pumps is to __________.

prevent an internal explosion in the pump when it is overheated

enable a visual inspection of the pump while it is running

insure the proper alignment of the pump coupling to the driver

permit internal components that are subjected to high erosion conditions, to be replaceable thereby extending the service life of the pump
