Q

Oil flowing through the sight glass in the line between the lube oil gravity tank and main sump indicates the __________.

🔍 Key Concepts

• Purpose of a lube oil gravity tank in relation to the main sump and pump suction • Normal direction of flow between gravity tank and main sump during proper operation • What condition would cause oil to move through the sight glass line unexpectedly or continuously

💭 Think About

• Think about when oil would actually travel from the gravity tank down toward the sump. Under what condition does the system "need" oil from above? • If the lube oil pump stops or a strainer clogs, what happens to flow and pressure in the system—does that make oil move through this particular line? • Would a completely full sump cause oil to be drawn from the gravity tank, or would it cause the opposite behavior?

✅ Before You Answer

• Identify the normal function of the gravity tank: is it a backup supply, a head-maintaining device, or an overflow tank? • Decide whether oil moving in this line indicates a demand for makeup oil or an excess of oil in the sump. • Mentally trace the flow path: gravity tank → sight glass line → sump. Under which option would this path actually be used?
