Recharge and Repair of Hydropneumatic Accumulators

Hydraulic Accumulators

Hydraulic accumulators are commonly used to compensate for leaks in hydraulic systems where maintaining constant pressure is necessary, as an energy reserve, as impulse dampers, or as volume compensators in case of thermal variations.

When choosing an accumulator, several factors need to be considered:

  • The maximum indicated pressure should never be exceeded, and considering possible temperature increases, the working pressure should be about 80% of the accumulator’s maximum operating pressure.
  • To ensure optimal operation of the hydraulic accumulator, the minimum working pressure should be approximately 10% higher than the pre-charge pressure of the accumulator.
  • The available oil volume should be analyzed on a case-by-case basis.
