At Sagroparts, you will find hydraulic accumulators for hydraulic systems used in agriculture, construction and machinery applications. Our range includes bladder accumulators in several sizes, pressure ratings and connection types, as well as charging kits for checking and adjusting pre-charge pressure. A hydraulic accumulator helps store energy, smooth pressure fluctuations and reduce stress on the hydraulic system during rapid load changes.
What is a hydraulic accumulator?
A hydraulic accumulator is a component used to store hydraulic energy under pressure. In a bladder accumulator, the hydraulic oil is separated from a compressible gas by a flexible bladder. As system pressure increases, the gas is compressed and energy is stored in the accumulator. When additional hydraulic power is required, the stored energy can be released back into the system.
Hydraulic accumulators are commonly used to absorb pressure shocks, reduce pulsations and stabilise pressure in hydraulic systems. They can also serve as an energy reserve during short-term load peaks.
Different sizes and pressure ratings
The right hydraulic accumulator depends on the design and operating conditions of the hydraulic system. Sagroparts offers bladder accumulators with different volumes, pre-charge pressures and maximum working pressures.
A smaller accumulator may be suitable for pressure equalisation and damping, while a larger volume may be required when more hydraulic energy needs to be stored. Always check the system pressure, required volume and connection type before selecting a model.
How to choose the right hydraulic accumulator
For the accumulator to operate correctly, it must be matched to the hydraulic system. Pay particular attention to:
Volume: Match the accumulator capacity to the amount of energy or oil volume the system needs to store.
Working pressure: Make sure the accumulator's maximum pressure rating is suitable for the system's highest operating pressure.
Pre-charge pressure: The pre-charge must be matched to the system's operating conditions and pressure range.
Connection: Check the thread type and size to ensure compatibility with the installation.
A correctly sized accumulator helps provide smoother operation and can reduce stress on other hydraulic components.
Inspection and maintenance of hydraulic accumulators
The pre-charge pressure should be checked regularly, as the correct gas pressure is essential for proper accumulator performance. A suitable charging kit can be used to measure and adjust the pressure when required.
Also inspect the accumulator and its connections for leaks or damage. Regular maintenance helps maintain a stable hydraulic system and supports a longer service life for both the accumulator and other hydraulic components.
