Bladder Accumulator
Summary
Modern hydraulic machinery needs to respond quickly to changing operating conditions. A hydraulic circuit may require a high flow rate for a few seconds, experience pressure fluctuations during valve operation, or need stored energy for a backup function.
An accumulator provides a solution by storing hydraulic energy and releasing it when required. When properly selected, it can complement the hydraulic pump and help improve the reliability and performance of the complete system.
What Is an Accumulator in a Hydraulic System?A hydraulic accumulator is a pressure vessel designed to store hydraulic fluid under pressure. In gas-charged designs, compressed nitrogen is used to store the energy.
When the hydraulic pump produces more flow than the system immediately requires, some of the fluid can enter the accumulator. The increasing hydraulic pressure compresses the nitrogen.
When the system subsequently requires more flow, the compressed nitrogen expands and forces hydraulic fluid back into the circuit.
This charging and discharging process allows the accumulator to respond to changes in hydraulic demand.
Where Are Hydraulic Accumulators Used?Hydraulic accumulators are found in many industrial and mobile hydraulic applications. Their function depends on the way they are integrated into the circuit.
