During the operation of a lube oil centrifuge, a thin emulsion interface occurs between the lube oil and seal. The position of this interface is determined by the __________.
• centrifugal separation of oil, water, and sludge in a purifier/clarifier • how the interface level (oil/water boundary) is physically controlled in a lube oil centrifuge bowl • the role of ring dams / gravity discs / discharge rings in setting where separated liquids leave the bowl
• In a centrifuge, what actually fixes the radial position of the oil–water interface: the amount of water you start with, or some fixed geometric feature of the bowl? • Which component among the options directly controls at what radius one liquid can overflow or discharge from the rotating bowl? • If you changed this component’s size, would the interface move inward or outward, and would that change separation quality?
• Identify which option refers to a fixed geometric dimension that determines overflow radius inside the bowl. • Distinguish between parts that affect capacity or efficiency (like number of disks) versus those that set liquid levels. • Verify which part in your engineering texts is described as controlling the gravity disc / ring dam diameter that sets interface position.
