🔍 Key Concepts

• This is a self-cleaning centrifugal purifier used for fuel or lube oil separation • In such purifiers, dirty oil feed, seal water, light phase (clean oil), and heavy phase (water) each have distinct flow paths and outlet/ inlet positions • The light phase (oil) normally exits near the top through a paring disc, while the heavy phase (water) exits separately, and the feed usually comes up through the center

💭 Think About

• Look at the color inside port A and follow where that same color appears inside the bowl: does it lead into the disc stack, or away from it? • Compare the vertical level of A with where the light phase and heavy phase collect in the bowl: which phase (oil or water) is sitting higher in the bowl under centrifugal force? • Ask yourself which of the three horizontal connections (A, B, C) is likely to be an inlet versus outlets, based on whether their internal passages point into the machine or out from the paring discs

✅ Before You Answer

• Trace the internal passage from A all the way into the machine and see whether it connects to a paring disc (discharge) or to an inlet / water operating system • Identify where the dirty oil actually enters the rotating bowl (usually up through the spindle into the distributor) and see which external port lines up with that path • Notice that light oil (less dense) collects toward the center/top, while heavy water (more dense) collects toward the outside/bottom; match port A’s height to the likely phase it would carry if it is a discharge
