Inspection and maintenance of hydraulic station accumulator
BOP Accumulator Requirements & Inspections
When hydraulic oil is forced into the accumulator by a small volume, high-pressure pump, the nitrogen is compressed, storing potential energy. When the BOP''s are activated the pressured oil is released, either
Guidelines for Understanding and Maintaining
A hydraulic accumulator is used for one of two purposes: either to add volume to the system at a very fast rate or to absorb shock. Which function it will perform depends upon its pre-charge. If the accumulator is to be used to

6 FAQs about [Inspection and maintenance of hydraulic station accumulator]
Do hydraulic accumulators need to be inspected?
Yes, hydraulic accumulators need to be inspected. For example, the correct gas pre-charge pressure must be maintained for proper functioning and optimum service life. Additionally, periodic inspection, testing, and certification may be required by law, as accumulators are considered pressure vessels.
How to maintain a hydraulic accumulator?
A hydraulic accumulator functions as a source of pressurized fluid. Conversely, when the pressure falls off, the accumulator supplies oil to the hydraulic system. Using common sense for a good maintenance. Think before act is the most important step but the one most overlooked. When talking about Hydraulic always try to work in a clean environment.
What should I do if my hydraulic accumulator fails?
Replace the hydraulic fluid if necessary. Operating Pressure: Monitor the operating pressure of the accumulator to ensure it is within the recommended range. Excessive pressure can strain the accumulator and lead to premature failure. Adjust the pressure as needed.
What does a hydraulic accumulator do?
A hydraulic accumulator is used for one of two purposes: to increase the system’s volume at a very high pace or to absorb stress. Its precharge determines the function it will carry out. If the accumulator is utilised to add volume to the system, its precharge must be slightly below the maximum system pressure to allow oil to enter.
What triggers an inspection of a hydraulic accumulator?
Inspection of a hydraulic accumulator may be required at predetermined intervals (i.e. every two, five or 10 years) or when a certain percentage of usable design life is deemed to have been reached. This particularly applies to hydraulic accumulators which have relatively large volumes and operate at high working pressures.
What is the importance of accumulator maintenance?
Never overpressure any accumulator during precharge or operation as the vessel could explode. As this procedure implied safety measures must be carried out by skilled person. Maintenance is the first step to eliminate malfunction and breakdowns in the hydraulic system. Hydraulic cylinder used for spooling device part of LARS system.
