Q

If a ship service air compressor operating in intermittent service were failing to unload, the __________.

🔍 Key Concepts

• Intermittent service for an air compressor (starts and stops based on receiver pressure) • What unloading means in a reciprocating air compressor (what changes between loaded and unloaded running) • Effect of a failure to unload on running time vs receiver pressure

💭 Think About

• Think about what should normally happen when the receiver reaches its set pressure and the compressor unloads—what changes in its operation? • If the unloading mechanism failed, what condition would remain on the compressor: is it still compressing air or just spinning freely? • How would continuous compression affect the pressure in the air receiver and the need for more or less lubrication?

✅ Before You Answer

• Be clear on the definition of unloaded vs loaded operation in a compressor (air flow vs no air flow). • Ask yourself whether a failure to unload would make the machine stop, run less, or run more often/longer. • Consider whether a failure to unload would more likely cause high receiver pressure (with safeties lifting) or low receiver pressure—and eliminate options that don’t fit that behavior.
