🔍 Key Concepts

• Study how liquid flows through a centrifugal purifier: where does the separated clean liquid collect before leaving the bowl? • Compare what an upper ring chamber would look like versus a set of regulating rings in a sectional drawing. • Think about which terms (like comminuting device or pump chamber cover) normally belong to other types of machinery, not fuel/oil purifiers.

💭 Think About

• Look closely at label B: is it pointing to a cavity (space), a stack of thin parts, or a solid cover? What kind of name would match that shape? • Trace the path from the disc stack outward and upward. Does label B appear to be part of the flow passage for the clarified liquid, or is it a structural piece protecting another component? • Ask yourself which option describes one part versus a group of parts. Does the illustration at B show multiple discrete items or one defined space?.

✅ Before You Answer

• Verify whether B encloses a volume where liquid could collect or simply marks a mechanical cover plate. • Confirm if there is any visible stack of thin rings at B; if not, reconsider choosing "set of regulating rings." • Eliminate answers that normally apply to sewage treatment/comminuting equipment or to the external pump casing, since this drawing is a purifier bowl cross‑section.
