Q

Which ring dam arrangement should be used for centrifugal purification?

🔍 Key Concepts

• Centrifugal purifier bowl geometry – how heavier water and lighter oil separate in a rotating bowl • Ring dam (gravity disc) diameter – how changing inside vs outside diameter affects the radial position of the oil–water interface • Oil loss vs water separation – what happens if the interface moves too far inward or outward

💭 Think About

• Picture the bowl in cross‑section: where do you want the oil–water interface to sit relative to the water outlet and the oil outlet so you don’t lose oil? • If you increase the ring diameter, does the oil–water interface move closer to the center or farther out toward the bowl wall? What does that do to oil loss? • Which combination (large/small, inside/outside diameter) keeps the interface just outside the water outlet, so only water discharges and oil stays inboard?

✅ Before You Answer

• Be clear on whether the ring dam is described by its inside diameter or outside diameter and how that relates to the flow path of separated water and oil • Think about the effect of a larger vs smaller diameter ring on the pressure balance and thus on the interface position • Verify which choice best prevents oil from reaching the water discharge while still allowing continuous water removal
