An excessive pressure differential across a lube oil strainer could indicate __________.

🔍 Key Concepts

• Pressure differential across a strainer and what creates it • How flow restriction in a strainer or filter affects pressure before and after it • Which conditions would increase differential pressure vs. which would decrease or bypass it

💭 Think About

• Think about what happens to pressure on the upstream and downstream sides of a strainer when it starts to plug up. • Consider whether incorrect installation of elements would block flow more, less, or the same, and how that would show up on differential pressure. • Ask yourself what a relief valve stuck open would do to system pressure and whether that would raise or lower the differential across the strainer.

✅ Before You Answer

• For each choice, decide: does this condition increase restriction to flow through the strainer, or bypass/reduce it? • Visualize the pressure gauges on both sides of the strainer and how each condition would change their readings. • Eliminate any option where the condition would clearly reduce or eliminate pressure differential instead of increasing it.
