Q

The three-wing device used in the tubular bowl purifier, is held in place and forced to rotate at bowl speed by the __________.

🔍 Key Concepts

• Tubular bowl purifier construction – how internal components are mounted and driven • Function of a three-wing (spreader) device – what it must do during operation • Difference between parts that locate/center a component and parts that transmit rotational drive

💭 Think About

• Which part of the bowl or its fittings is most likely designed to physically drive another component, not just guide it? • What type of connection is best for transmitting full bowl speed to a relatively small internal part without slipping? • Think about maintenance: which part would a technician expect to check for shear, wear, or damage if the three‑wing device stopped rotating with the bowl?

✅ Before You Answer

• Identify which choice clearly provides positive mechanical drive (not just friction or light spring pressure). • Ask yourself which option would most reliably make the three‑wing device rotate exactly at bowl speed. • Consider which component would normally be a hardened drive element in rotating machinery (pin vs grooves vs springs).
