Question 1 of 27070

A precharged bladder-type accumulator used in a hydraulic system, can be potentially dangerous if ______.

🔍 Key Concepts

• Bladder-type accumulator construction and operation (poppet, bladder, gas charge, hydraulic fluid side) • Safe charging practices for accumulators, including which gases are acceptable • What happens if mechanical parts fail while the accumulator is under normal working pressure

💭 Think About

• Think about which situation could cause a sudden, uncontrolled release of pressure or physical parts, rather than just normal wear or reduced performance. • Which of these options describes a condition that is actually standard practice versus one that would be a clear safety hazard? • Consider what happens when the pressure boundary between gas and fluid or between internal parts and the outside environment is unexpectedly lost.

✅ Before You Answer

• Identify which gas is normally used and considered safe for precharging hydraulic accumulators. • Consider whether fluid briefly touching internal components always equals a serious hazard, or may just reduce efficiency or damage parts over time. • Ask: in which option could there be a sudden, violent release of gas or parts at system pressure, posing immediate danger to personnel?
