Q

In a disk-type lubricating oil purifier, __________.

🔍 Key Concepts

• Disk-type lubricating oil purifier operation – how the bowl, water seal, and sludge discharge work • Water seal function – why sealing water is used and what happens if the seal is lost • Start-up procedure for a centrifugal purifier – order of supplying sealing water and oil

💭 Think About

• Think about what the water in a disk-type purifier is actually doing inside the bowl. Is it mainly for cooling, sealing, or lubrication? • What happens if the water seal is not maintained properly around the bowl ring gasket—would oil, water, or sludge go where it shouldn’t? • During start-up, which must come first to form the correct interfaces in the bowl: sealing water or oil feed?

✅ Before You Answer

• Identify the purpose of sealing water in a disk-type purifier (hint: it has more to do with a liquid ‘barrier’ than with cooling). • Consider whether all dirt and sludge could really be carried out automatically with cooling water in normal operation, or if it is collected somewhere. • Ask yourself if feeding sealing water before oil is necessary to establish the proper internal interfaces and water seal, or if that would be harmful.
