Accumulator performance calculation
Suggested exercises and observations
1. Practice charging an accumulator under safely monitored, workshop conditions.
♦ Follow the manufacturer's instructions using the recommended charging kit.
Experiment 1: Accumulators nitrogen pressure will change with temperature.
Question 1: Is it necessary to use a conversion chart to ensure you set the correct gas pressure for the current ambient temperature?
Experiment 2: It is a legal requirement to include a drain down safety block on all storge accumulators.
Question 2: Must all accumulators include a safety block?
Experiment 3: Accumulators are considered pressure storage vessels and must, therefore, comply with EU's PED, US's ASME legislation.
Question 3: Is it OK to adjust the safety block relief valve?
