Pressure monitoring for hydraulic accumulators
The correct pre-charge pressure (p₀) is crucial for hydraulic accumulator performance and availability. Deviations can lead to energy losses, premature wear or even system downtime. With HYDAC's smart monitoring solutions, you can keep an eye on the pre-charge pressure – for maximum efficiency and process reliability.

The correct pre-charge pressure is key for a hydraulic accumulator's performance System performance starts with the right pre-charge pressure
The pre-charge pressure (p₀) in a hydraulic accumulator behaves in a similar way to the tyre pressure in a car: if it is too high or too low, system stability suffers. A correctly set p₀ – matched to the minimum system pressure, ambient temperature and intended use – is crucial for the accumulator's functioning, response behaviour and service life. Temperature-dependent changes in the volume of nitrogen require corresponding compensation during charging. An accumulator will only work efficiently and reliably protect the system against pressure surges, energy losses and premature wear if the pre-charge pressure is correct.
A p₀ which deviates from this jeopardises the system availability The correct pre-charge pressure protects against performance losses, wear and system failures
An incorrectly set pre-charge pressure impairs the hydraulic accumulator's functioning and has an impact on the entire system's performance and availability. If the accumulator can no longer reliably fulfil its task in the system, process stability suffers. This manifests itself in reduced part quality in the case of presses, for example, or in an overall increase in a system's energy requirements.
In the long term, an incorrect pre-charge pressure doesn't just lead to premature wear or destruction of the separation element in the accumulator. It also impairs the surrounding system components - and in the worst case scenario, even leads to machine downtime.
A precisely set hydraulic accumulator pre-charge pressure isn't just a technical detail. It's a decisive factor for error-free, reliable and economical system operation.
Examples consequences of the incorrect pre-charge pressure (p₀) in various applications
- Machine tools (accumulator charging function)
Poor performance → loss in productivity - Presses, test benches (performance support)
Higher energy consumption - Mobile machines (emergency functions: brakes, steering, suspension, etc.)
Impaired safety function, component fatigue, reduced comfort
