🔍 Key Concepts

• Alignment marks on centrifuge bowl components must form a straight radial line when properly reassembled • On Alfa‑Laval MAPX separators, the alignment line has a specific position relative to the rectangular discharge ports to keep the bowl in balance • Incorrect alignment (marks not in one line, or in the wrong place vs. the ports) can cause imbalance and poor separation

💭 Think About

• Look at each figure and ask: do all visible punch marks lie on the same straight radial line, or are one or more shifted around the circumference? • Once you find the figure where the marks line up, check where that line falls compared with the rectangular discharge slots: is it centered on a slot or between two slots? Which does the manufacturer specify? • Which figures clearly show a situation that would create uneven weight distribution around the bowl (marks misaligned with each other or oddly placed vs. the ports)?

✅ Before You Answer

• Confirm that the correct choice shows all alignment marks present and in one straight radial line from inner to outer piece • Verify whether that radial line is in the proper spot relative to a discharge opening (exactly in line with a slot, or between two slots—recall the manufacturer’s instruction) • Eliminate any option where any mark is missing, doubled where it shouldn’t be, or circumferentially offset from the others
