If there is a sudden drop in the capacity of a reciprocating air compressor, you should check for __________.

🔍 Key Concepts

• Volumetric efficiency of a reciprocating air compressor • Effects of leakage past pistons and valves on delivered air volume • Difference between a fault that changes capacity/volume vs. one that affects pressure control or speed

💭 Think About

• Which of these faults would cause air to leak back or not be drawn in properly, so that the same number of strokes moves less usable air? • Which option is more likely to cause a gradual or sudden drop in delivered volume at roughly the same running conditions, rather than changing set pressure or cut‑in/cut‑out behavior? • For each choice, ask: does this mainly affect air quantity per stroke, machine speed, or control of starting/stopping at a set pressure?

✅ Before You Answer

• Identify which options directly lower air delivery per stroke (volumetric efficiency) rather than just pressure setting or switching. • Consider whether excessive speed would usually increase or decrease capacity in the short term, ignoring long‑term wear. • Distinguish between a defect in the compressor internals (that move/compress air) and a defect in the pressure control system (that just turns the compressor on or off).
