Which of the following problems will occur if a manually cleaned disk-type centrifugal lube oil purifier contains insufficient sealing water prior to admitting oil flow to the bowl?
• Function of sealing water in a disk-type centrifugal purifier • Relationship between light phase (oil) and heavy phase (water/solids) discharge ports • What happens in the bowl if the water seal is not established before oil admission
• Think about why sealing water is introduced into the bowl before the oil. What physical separation inside the bowl is it creating? • If there is not enough water, what phase (oil or water) will occupy the space near the heavy phase discharge? How would that affect where the oil goes? • Which of the listed problems directly relates to an incorrect interface position between oil and water in the bowl rather than temperature or centrifugal force issues?
• Verify how a proper water seal keeps oil from reaching the heavy phase discharge ports. • Check which option describes a flow-path error (where the oil ends up) rather than a change in oil quality or temperature. • Confirm that the centrifugal force and bowl speed are essentially unchanged by the amount of sealing water; only the interface location is affected.
