LO Week 18

A centrifugal separator is a rotating device used to purify lubrication oil by removing water and solid contaminants. It works on the principle of centrifugal force—heavier particles are forced outward, while lighter oil remains in the center.

• True

• False

Centrifugal Separators in Lube Oil Treatment

Benefits in the Lube Oil System:__________

• Removes free water that causes corrosion and microbial growth

• Extracts metal particles and carbon deposits

• Maintains viscosity and lubricating properties

• Reduces the need for frequent oil changes

• Protects engine components like bearings, crankshaft, and pistons
