Q

The rubber bladder or separator bag installed in a hydraulic accumulator should only be filled with __________.

🔍 Key Concepts

• Hydraulic accumulators and the purpose of the bladder/separator • Properties of different gases under pressure (oxygen, nitrogen, hydrogen, water vapor) • Fire and explosion hazards when gases contact oil under high pressure

💭 Think About

• Which of these choices will not react dangerously with hydraulic oil when highly compressed? • Which gas is commonly used as an inert charging gas in many industrial pressure systems? • What would happen if oil and a highly reactive gas mixed under high pressure and temperature inside an accumulator?

✅ Before You Answer

• Verify which gas is considered inert and non‑reactive in this context • Eliminate any gas that is combustible or supports combustion when mixed with oil under pressure • Remember that the bladder gas must be dry to avoid internal corrosion or freezing issues
