Function, section
General information
Hydraulic accumulators are hydrostatic devices capable of storing a certain amount of energy in order to release it to the hydraulic system when needed.
Fluids only possess low compressibility; however, gases are highly compressible. The working principle of all gas-loaded hydraulic accumulators is based on this difference.
The difference between bladder and diaphragm type accumulators lies in the type of separator element. Hydraulic accumulators essentially consist of a fluid section and a gas section with a gas-tight separator element.
The fluid section has a connection to the hydraulic circuit.
If a higher liquid pressure is applied to a specific quantity of pressurized gas, the gas volume decreases as the liquid pressure increases, with the gas pressure increasing with the liquid pressure.
If the pressure of the fluid decreases, the fluid is pushed back into the hydraulic system by the expanding gas until the pressure is balanced again.
Bladder-type accumulator
Bladder-type accumulators consist of a seamless cylindrical pressure container (1) made of high-strength steel. An elastic bladder (2) mounted inside the container separates the accumulator into a gas side and a fluid side.
Via the gas valve (4), the bladder is filled with nitrogen up to the intended gas filling pressure p0.
The oil valve (3) located inside the oil port of the bladder-type accumulator closes if the pressure on the gas side is higher compared to the fluid side. This prevents the bladder from entering the oil channel and being destroyed.
When the minimum operating pressure is reached, a small fluid volume (approx. 10% of the hydraulic accumulator's nominal volume) should remain between the bladder and the oil valve in order to prevent the bladder from hitting the valve during each expansion process.
The gas valve (4) consists of sealing cap (4.1), gas valve insert (4.2), gas prefill valve body (4.3), and O-ring (4.4). These parts can be replaced individually.
The type cap (7) includes the technical data and features of the hydraulic accumulator.

Calculation
Pressures
The following pressures are of decisive importance for the calculation of an accumulator:
p0 Gas filling pressure at room temperature and empty fluid chamber
p0 (t) Gas filling pressure at operating temperature
p0 (tmax) Gas filling pressure at maximum operating temperature
p1 Minimum operating pressure
p2 Maximum operating pressure
In order to achieve the best utilization of the accumulator volume possible as well as a long life cycle, compliance with the following values is recommended:
p0 (tmax) ~ 0.9 × p1 (1)
The highest hydraulic pressure should not exceed four times the filling pressure, as otherwise too much stress will be put on the elasticity of the bladder, resulting in too great a compression change with strong gas heating:
p2 ≦ 4 × p0 (2)
The life cycle of the accumulator bladder is the higher the smaller the difference between p1 and p2 is. However, the operating ratio of the maximum accumulator capacity will also be reduced accordingly.
Oil volume
According to the pressures p0 … p2, the gas volumes V0 … V2 will result.
In this process, V0 simultaneously is the nominal volume of the accumulator.
The available oil volume ΔV corresponds to the difference of the gas volumes V1 and V2:
ΔV ≦ V1 – V2 (3)
The gas volume variable within a pressure differential is determined by the following equations:
For an isothermal state change of gases, i.e. when the change of the gas cushion happens so slowly as to leave sufficient time for a complete thermal exchange between the nitrogen and its environment, therefore keeping the temperature constant, the following applies:p0 × V0 = p1 × V1 = p2 × V2 (4.1) For an adiabatic state change, i.e. a quick change of the gas cushion accompanied by a temperature change of the nitrogen, the following applies:p0 × Vχ0 = p1 × Vχ1 = p2 × Vχ2 (4.2)
χ = ratio of the specific gas heats (adiabatic exponent), for nitrogen = 1.4
In practice, state changes rather follow adiabatic laws. Often charging is isothermal and discharge is adiabatic.
Considering the equations (1) and (2), ΔV is between 50% and 70% of the nominal accumulator volume. The following applies as a guiding principle:
V0 = 1.5 … 3 × ΔV (5)
Calculation diagram
For graphic determination, the formulas (4.1) and (4.2) are converted into diagrams. Depending on the task, the available oil volume, the accumulator size or the pressures can be determined.
Correction factor Ki and Ka
The equations (4.1) and (4.2) apply to ideal gases only.
The behavior of real gases, however, will show considerable variation at operating pressures above 200 bar which will have to be accounted for by correction factors. These can be taken from the following diagrams.
The correction factors the ideal sampling volume ΔV is to be multiplied with lie within a range of 0.6 … 1.
Application of the calculation diagrams
Isothermal state changes p0 = 1 … 90 bar
Isothermal state changes p0 = 100 … 300 bar
Adiabatic state changes p0 = 1 … 90 bar
Adiabatic state changes p0 = 100 … 300 bar
Applications
Various applications exist for hydro-pneumatic accumulators:
▶ Energy storage in order to save pump drive power in intermittent operation systems.
▶ Energy reserve for emergencies, e.g. upon failure of the hydraulic pump.
▶ Compensation of leakage losses.
▶ Impact and vibration absorption in case of periodic vibrations.
▶ Volume compensation in case of pressure and temperature changes.
Mode of operation
Fluids are almost incompressible and therefore cannot store pressure energy. Hydro-pneumatic Rexroth accumulators use the compressibility of a gas for fluid storage. Exclusively use nitrogen of cleanliness class 4.0!

Project planning information
Bladder-type accumulators have to be safely and permanently fastened to the machine or system using mounting elements. The fastening is intended to keep the oil port tension-free. Particularly, no tension forces or static or dynamic inertia forces should be applied to the oil port.
Thermal expansion of the supporting structure and vibrations originating from the environment should be considered in the selection of suitable mounting points.

Important notices
Intended use
Rexroth bladder-type accumulators type HAB..-6X are intended for the set-up of hydraulic drive systems in stationary mechanical engineering and plant construction.
In mobile applications or applications in which acceleration forces are applied to the bladder-type accumulator during intended use, its use is permitted only following release by the competent Rexroth product manager. Please contact technical sales for this.
Rexroth bladder-type accumulators type HAB..-6X are not intended for private use.
Safety instructions for hydraulic accumulators
For the hydraulic accumulator type HAB..-6X, observe the operating instructions 50171-B. The machine end-user will have sole responsibility for compliance.
General notices for hydraulic accumulators in hydraulic system can be found in ISO 4413.
Keep all documents included in the delivery in a safe place; they will be required by the expert in recurring tests.
Legal provisions
Hydraulic accumulators are pressure vessels and subject to the application national provisions and/or regulations valid at the place of installation.
In Germany, the Ordinance on Industrial Safety and Health (BetrSichV) applies.
Special regulations are to be observed in shipbuilding, aircraft construction, mining, etc.
Authorized persons
According to Ordinance on Industrial Safety and Health (BetrSichV), only authorized persons may carry out tests.
Authorized persons are such persons having obtained the required expert knowledge through professional training, experience and recent professional activity.
Safety equipment
Notice:
Hydraulic accumulators have to be secured against operation outside of the admissible limits according to Pressure Equipment Directive 2014/68/EU.
In order not to exceed the maximum operating pressure, we recommend the use of an accumulator shut-off block type ABZSS according to data sheet 50131.
