Accumulator Technology. EN 3.000.18/04.21 1. HYDAC ACCUMULATOR TECHNOLOGY FLUID ENGINEERING EFFICIENCY VIA ENERGY MANAGEMENT.

HYDAC Accumulator Technology has many years’ experience in the research & development, design and production of hydraulic accumulators. All of HYDAC’S bladder, piston, diaphragm and metal bellows accumulators are part of an unbeatable product range which supports hydraulic systems in almost all sectors at a component or unit level.

The main applications of our accumulators are: z Energy storage z Emergency and safety functions z Damping of vibrations, fluctuations, pulsations (pulsation dampers), shocks (shock absorbers) and noise (silencers) z Suction flow stabilisation z Media separation z Volume and leakage oil adjustment z Weight equalisation z Energy recovery

Accumulators improve the performance of the entire system. Here are some of their advantages in more detail: z Improved functions z Increased service lives z Reductions in operating and maintenance costs z Reductions in pulsations and noise

On the one hand, this means greater safety and comfort for the operator and the machine. On the other hand, HYDAC accumulators enable efficient working in all applications. 2.

p0 ≤ 0.9 • p1 with a permitted pressure ratio of

p2 : p0 ≤ 4 : 1

For HYDAC low pressure accumulators, the following must also be taken into account:

Type SB40: p0 max = 20 bar

Type SB35H: p0 max = 10 bar

 ‚ ƒ Piston accumulators

p0,tmin ≥ 2 bar

 ‚ ƒ Diaphragm accumulators

a) Permitted pressure ratio: p2 : p0 Weld type: The pressure ratio of weld-type diaphragm accumulators is between 4 : 1 and 8 : 1, depending on the design – see catalogue section Diaphragm Accumulators, No. 3.100, section 3.1. Screw type: All sizes: 10 : 1 Other pressure ratios on request  ‚ ƒ b) p0 ≤ 0.9 • p1 Metal bellows accumulators (e.g. corrugated bellow version) The max. permitted or optimal pre-charge pressure of a metal bellows accumulator (with corrugated or diaphragm bellows) must be determined for each application and each design version by providing information on the particular operating conditions and consulting with HYDAC.

 ‚ ƒ The specified values are maximum values and must not be considered as referring to a prolonged load. The tolerable pressure ratio is influenced by the geometry, temperature, fluid, flow rate and gas losses caused by physical properties.  The accumulator is pre-charged with nitrogen. The separating element (piston, bladder, diaphragm, metal bellows) shuts off the fluid port. ‚ Temperature effects must be taken into account when choosing the minimum operating pressure. The minimum operating pressure

must also be higher than the gas pre-charge pressure (p1 > p0). This should prevent the separation element from striking the fluid port every time fluid is discharged. ƒ Once the max. operating pressure is reached, the effective volume ΔV is available in the accumulator:

p0 = pre-charge pressure V0 = effective gas volume t0 = pre-charge temperature

p1 = minimum operating pressure V1 = gas volume at p1 tmin = min. operating temperature p = maximum operating pressure V = gas volume at p t = max. operating temperature 2 2 2 max EN 3.000.18/04.21 17 9.2.

In 9.3.1 ASPlight order to obtain optimum utilisation of the ASPlight is an intelligent application accumulator volume, the following pre- which takes real gas behaviour into charge pressures are recommended: account It enables you to calculate 9.2.1 Recommended values all the necessary parameters such as For energy storage: pressure, volume and temperature in different units for gases such p = 0.9 • p 0,t max 1 as nitrogen or helium. Additional information fields help to evaluate For shock absorption: the result and determine the type of accumulator. p = 0.6 to 0.9 • p 0,t max m ASPlight is aimed at users who need (p = average operating pressure for m to determine the main accumulator free flow) parameters in a short space of time.

For pulsation damping: 9.3.2 p0-calculator The p -calculator is a simple p = 0.6 • p 0 0,t max m conversion tool for determining the (p = average operating pressure) m pre-charge pressure (p0) in the hydraulic or accumulator at a specific temperature. All that is needed is the reference p0,t max = 0.8 • p1 (for several operating pressures) pre-charge pressure and the current temperature of the hydraulic During operation, the separating element accumulator measured on the gas side.

The online tool display is optimised for both Since the volume of the gas increases as smartphones and desktops and is the temperature increases, the pre-charge available online around the clock. pressure must be determined at the The p -calculator offers reliability maximum operating temperature using the 0 recommended values. for the inspection and any required correction of the accumulator’s 9.2.2 Limits for gas pre-charge pre-charge pressure outside of the pressure reference temperature. See section 9.1. 9.3.3 Accu-MOUNT 9.2.3 Temperature effect With the Accu-MOUNT, the suitable So that the recommended pre-charge clamps, consoles and accumulator pressures can be maintained, even at mounting sets can be identified on the relatively high operating temperatures, basis of the accumulator designation, the p0 charge for charging and testing cold the part number or its characteristics. accumulators must be selected as follows: These accessories can then be added to the request list. tcharge + 273 p0, t charge = p0,t max • You can also find links to the t + 273 max corresponding product pages on our t = t (pre-charge temperature in °C) website and download 3D models, 0 charge brochures and other information. To take the temperature influence into account when sizing accumulators, The Accu-MOUNT can find the perfect p at t must be selected as follows: mounting equipment for HYDAC 0 0 hydraulic accumulators in an instant.
