🔍 Key Concepts

• Self-cleaning purifier bowl operation – how the sliding bowl bottom opens and then has to be re-closed after sludge discharge • Difference between process liquid lines (oil/water inlet and outlet) and the operating water lines that control opening/closing of the bowl • Flow path for closing water: where it must enter to build pressure under the sliding bowl bottom and start the closing sequence

💭 Think About

• From the illustration, which labeled connection is clearly positioned to admit water directly under or around the sliding bowl bottom, rather than into the separation chamber? • Which labeled item is least likely to be a simple casing or structural part, and most likely a line or port connected to the operating water control system for opening/closing? • Consider how the desludging cycle ends: after the bowl has opened to discharge sludge, what must happen hydraulically to move the sliding bottom back up, and through which port would that water have to be supplied?

✅ Before You Answer

• Identify which of F, P, Q, R is connected to the operating water space beneath the bowl, not to the main product/dirty oil circuit • Trace the mechanical linkage: the part that starts the closing sequence should cause water pressure to build below the sliding bowl bottom, so verify which label is in that location • Eliminate any labels that appear to be bowl shell, frame, or product outlet/inlet rather than a control-water connection
