How to determine the working pressure of an accumulator

The determination of the working pressure of an accumulator involves multiple factors, depending on the application scenario, the working requirements of the hydraulic system, and the type of accumulator. The following are some main steps and considerations for determining the working pressure of an accumulator:
Choose the appropriate type of accumulator: Different types of accumulators have different working pressure ranges and characteristics. For example, the pressure range of gas spring accumulators is usually between 5MPa and 35MPa, while the pressure range of hydraulic accumulators may be wider. Select the appropriate type of accumulator according to the requirements of the hydraulic system.
Calculate the volume of the accumulator: Based on the flow demand and working cycle of the hydraulic system, calculate the required volume of the accumulator. This helps determine the energy reserve that the accumulator can provide during operation.
Consider safety factors: When determining work pressure, safety factors also need to be considered. For example, in order to prevent system overload or accidents, appropriate pressure limits and safety valves should be installed.
Reference manufacturer’s advice: Accumulator manufacturers usually provide detailed information about working pressure, usage conditions, and maintenance recommendations. When determining work pressure, reference should be made to the manufacturer’s recommendations and ensure compliance with relevant standards and specifications.
Actual testing and adjustment: After determining the initial work pressure, actual testing and adjustment are required. By observing the performance of the accumulator during operation and the overall operation of the hydraulic system, necessary adjustments and optimizations are made to the working pressure.
Please note that the above steps and considerations only provide a basic framework, and the specific determination process may vary depending on the application scenario and the complexity of the hydraulic system.
