Q

A cloudy or milky appearing lube oil sample, taken from the main lubricating oil system could be caused by __________.

🔍 Key Concepts

• water contamination in lube oil and how it appears in a sample • how cooling water leaks or operating conditions can let water into the lube oil system • the role of gland sealing steam on turbines and how improper amounts can affect lube oil

💭 Think About

• If lube oil looks cloudy or milky, what physical change has likely occurred in the oil? Think about oil and water mixing. • Which of the options would most likely allow water to enter the lube oil system and form an emulsion? • How would too much or too little cooling water to the lube oil cooler influence the possibility of a leak and water getting into the oil?

✅ Before You Answer

• Identify which choices are directly related to water getting into the lube oil versus just changing its temperature. • Consider how gland sealing steam could introduce condensate (water) into lube oil if not properly controlled. • Ask yourself: which condition would most likely increase the driving force or opportunity for water to leak from the cooling side or steam side into the oil side?
