A precharged bladder-type accumulator used in a hydraulic system, can be potentially dangerous if _______________.
AI Explanation
The correct answer is D) the charging valve stem breaks while at normal working pressure.
A precharged bladder-type accumulator can be potentially dangerous if the charging valve stem breaks while at normal working pressure. This is because the high-pressure inert gas (typically nitrogen) within the accumulator will rapidly escape, potentially causing the accumulator to become a dangerous projectile.
The other options are incorrect because: A) the bladder contacting the poppet is not inherently dangerous, B) exposure of the inert gas to hydraulic oil is not a safety concern, and C) using dry nitrogen as the inert gas is a common and safe practice.
