🔍 Key Concepts

• Function of operating water spaces in a self-cleaning centrifugal purifier bowl • How the sliding piston opens and closes the bowl during sludge discharge • Difference between liquid used for mechanical actuation of the bowl and liquids used for sealing, lubrication, or system pressure

💭 Think About

• Look carefully at where space J is located in relation to the sliding piston and bowl bottom—does it look like it acts on moving parts, on seals, or on bearings? • Ask yourself which liquid in a purifier is retained under the bowl during normal separation and what its purpose is in the discharge cycle. • Compare the location of space J to the oil/water interface and to the shaft bearings—are they in the same area or clearly separate?

✅ Before You Answer

• Verify whether space J is in direct contact with the sliding piston area or with any bearing surfaces. • Check if the pathway from J leads to the discharge ports / bowl closing mechanism, or to any oil seal area. • Confirm that the function you select matches normal operation (steady separation), not the moment of sludge discharge or starting sequence.
