🔍 Key Concepts

• Centrifugal purifier operating as a separator and how the water seal works • The normal flow paths for clean oil discharge and water (and sludge) discharge • What happens when the water seal is lost inside the bowl

💭 Think About

• Visualize the internal bowl: when the seal is intact, where is the oil supposed to exit, and where is the water supposed to exit? • If the water seal is lost, which liquid (oil or water) will most easily escape through the wrong outlet, based on density and position? • Ask yourself: does losing the seal more likely cause water to get into the oil system, or oil to be discharged with the separated water?

✅ Before You Answer

• Review how a water seal is established at start-up in a centrifugal separator used for lube oil • Confirm which side (oil or water outlet) is at the larger radius and which is at the smaller radius in the bowl • Verify what typical casualty is described in manuals: which stream ends up in the other discharge when the seal breaks
