Question 1 of 27070

Leaking valves in a low pressure, reciprocating, air compressor can result from __________.

🔍 Key Concepts

• How dust and foreign particles affect sealing surfaces in valves and pistons • What happens to valve seats and valve plates when they are repeatedly impacted at high speed or high pressure • The difference between a valve leaking (not sealing) and a valve being overloaded but still intact

💭 Think About

• Ask which condition is most likely to physically damage or wear the valve seating surfaces so that they no longer seal tightly • Consider whether high discharge pressure or high speed alone would make a valve leak, or just stress it within its design limits • Think about which option describes gradual mechanical wear of the valve sealing surfaces rather than an operating condition that might cause other kinds of failures

✅ Before You Answer

• Identify which choices describe operating conditions (pressure, speed, stroke) versus direct mechanical wear on sealing surfaces • Think about how dust and dirt behave when drawn into an intake and pass through valves and seats • Before selecting, be sure you can explain in your own words how your chosen factor would cause a valve to leak rather than break

Question 1 of 27070

Leaking valves in a low pressure, reciprocating, air compressor can result from __________.

excessive compressor discharge pressure

operating the compressor at excessive speed

uneven piston stroke in the compressor

abrasion by dust and dirt
