🔍 Key Concepts

• Understand the difference between a pressure-feed system and a gravity-feed system for lubricating oil • Role of the lube oil reservoir/sump versus a gravity tank in a closed-loop system • Normal flow path of oil: from where it is pumped, through the bearings, and where it returns

💭 Think About

• Ask yourself: In a force-fed (pressure-feed) system, do the bearings receive oil directly under pump pressure, or mainly by gravity? • Think about which tank (reservoir/sump or gravity tank) is usually large, low in the system, and used to collect and store the bulk of the oil for recirculation. • Consider how a gravity tank is typically used: Is it the primary source the pump draws from, or a higher tank used for backup/emergency or head?

✅ Before You Answer

• Identify which option correctly has the pump suction taken from the main lube oil reservoir/sump, not from a small gravity tank. • Check which option shows the bearings receiving oil under pressure from the pump, not mainly by gravity feed. • Verify that the return oil goes back to the main reservoir/sump so the system can operate as a recirculating loop.

If the bearings of a piece of machinery are force-fed by a pressure-feed lubricating oil system, which statement is true?

The lube oil pump draws a suction on the lube oil gravity tank and discharges directly to the bearings. The return oil then gravity drains to the lube oil gravity tank.

The lube oil pump draws a suction on the lube oil reservoir/sump and discharges directly to the bearings. The return oil then gravity drains to the lube oil gravity tank which overflows to the lube oil reservoir/sump.

The lube oil pump draws a suction on the lube oil reservoir/sump and discharges directly to the bearings. The return oil then gravity drains to the lube oil reservoir/sump.

The lube oil pump draws a suction on the lube oil reservoir/sump and discharges to the lube oil gravity tank. The oil then gravity feeds the bearings and the return oil drains to the lube oil reservoir/sump.
