🔍 Key Concepts

• Operation of a self-cleaning centrifugal purifier bowl during the sludge discharge cycle • Role of the operating medium that acts on the sliding bowl bottom / operating slides • Difference between process liquids (light phase, heavy phase) and the separate control medium used to move parts

💭 Think About

• Look at the lower part of the bowl in the illustration: which passages and chambers are connected to the operating mechanism that opens the sludge ports? • Ask yourself: during discharge, what fluid fills and empties these operating chambers to move the sliding bowl bottom? • Which of the listed fluids would be clean, readily available, and non-damaging if it leaked into the separated liquids or sludge?

✅ Before You Answer

• Identify the operating water/hydraulic chambers shown near the sliding bowl bottom in the cross‑section • Distinguish between the separated product flows (light and heavy phase outlets) and the fluid that powers the discharge mechanism • Verify which medium is typically supplied from ship’s services for bowl opening/closing on automatic self-cleaning purifiers
