🔍 Key Concepts

• Centrifugal purification principles for lube oil and how density differences separate oil, water, and sludge • Effect of temperature and viscosity on lube oil flow and separation efficiency • What happens to water in oil at temperatures well below its boiling point in a purifier heater

💭 Think About

• Think about how preheating changes the lube oil’s viscosity and how that would affect separation in a centrifuge bowl rotating at high speed. • Ask yourself: Is the purpose of the heater to change the mechanical parts of the machine, the properties of the oil, or the state of the contaminants? • Consider what temperature lube oil heaters typically run at and whether that is enough to actually boil water out of the oil.

✅ Before You Answer

• Verify which choice directly improves the separation of oil, water, and solids by changing the oil’s properties (not the machine’s parts). • Check whether lube oil purifier heaters are normally hot enough to boil water (212°F / 100°C) or just warm the oil to lower viscosity. • Eliminate any answers that focus on effects that are secondary or incidental, rather than the main reason designers always include a preheater before the centrifuge.
