4 4 HAB Bladder-type accumulat Function, sectional drawing Standard ASME models Fluids are hardly compressible, whereas gases feature high compressibility. The operating principle of all gas-loaded hydraulic accumulats is based on this difference. Hydraulic accumulats basically consist of a fluid and a gas section with a gas-tight separating element. The fluid section is connected to the hydraulic circuit. When a certain amount of pressurized gas is pressurized to a higher fluid pressure, the gas volume decreases as the fluid pressure rises. When the fluid pressure falls, the fluid is pressed back into the hydraulic system through expansion of the gas until the pressure is again balanced. Bladder-type accumulat Bladder-type accumulats consist of a seamless cylindrical pressure vessel (1) made of high-tensile steel. The accumulat is subdivided into a gas and a fluid side by an elastic bladder (2) mounted in the interi of the vessel. The bladder is charged with nitrogen to the specified gas charge pressure p 0 by means of gas valve (4). 4 5 When the fluid is pressed into the accumulat, the gas in the bladder is compressed and hence the pressure increases. The gas volume reduces and on the fluid side, the fluid can flow into the accumulat. As soon as the pressure on the fluid side falls below the gas pressure, the accumulat is emptied. Fluid pt assembly (3) is provided in the oil pt of the bladder-type accumulat and closes when the pressure on the gas side is higher than on the fluid side. This prevents draining of the bladder into the oil channel and thus the bladder from being destroyed. MNR: SIZE: Gallon MAWP: 4 FD: WARNING:MAINTENANCE BY TRAINED PERSONNEL ONLY. 1.

7 Bladder-type accumulat HAB 7 Sizing calculations The majity of applications use accumulats to ste energy f intermittent duty cycles to provide a source of emergency power. In either case, the problem is determining the optimum size and precharge of the accumulat. Accumulat sizing is based on the gas charge. The change in gas volume and pressure determines the amount of liquid that can be added withdrawn. However, unlike mechanical springs, compressing a gas tends to heat it, raising the pressure above what would be expected from compression alone. Expanding a gas tends to cool it, reducing the pressure below that caused by expansion alone. Either of these effects can substantially affect accumulat sizing. Expansion ( compression) of a gas resulting in a change of gas temperature produces adiabatic expansion. When an accumulat is discharged rapidly, there is not enough time f sufficient heat transfer through the accumulat walls and adiabatic expansion occurs. If the expansion ( compression) occurs slowly, there is sufficient time f heat to be added ( subtracted) by the accumulat wall to maintain a constant gas temperature and isothermal expansion occurs. The median of these two states of expansion can be partially adiabatic. When carrying out the calculations f an accumulat, the following pressures are of primary imptance: p 0 = Gas pre-charge pressure at room temperature and with liquid chamber drained p 1 = Minimum operating pressure p 2 = Maximum operating pressure The following relationships apply: the gas pre-charge pressure is to be slightly lower than the minimum hydraulic pressure so that the bladder does not continually contact the oil valve (wear). p p 1 (1) The maximum hydraulic pressure is not to exceed 4 times the pre-charge pressure; otherwise, the elasticity of the bladder diaphragm will be adversely affected. Also, excessive changes in pressure result in considerable heating of the gas. Reducing the pressure differential between p1 and p2 increases bladder service life. On the other hand, it must be taken into account that a lower pressure differential also reduces the utilization of available stage capacity. Bladder-type accumulats p 2 4 p 0 (2) Oil volumes The gas volumes V 0 V 2 crespond to the pressures p 0 p 2. Here, V 0 is the rated volume of the accumulat. The available oil volume V cresponds to the difference between the oil volume V1 and V2. b) F adiabatic change of state of gases, the following fmula applies: p 0 V no = p 1 V n1 = p 2 V n2 (4.2) V = V 2 V 1 (3) The variable gas volume f a given pressure difference is determined accding to the following equations: a) F isothermal change of state of gases, the following equation applies: p 0 V o = p 1 V 1 = p 2 V 2 (4.1) The isothermal equation is used when the change in the gas volume takes place so slowly that there is sufficient time f the complete exchange of heat to take place between the nitrogen and its surroundings. The result is a constant temperature. n = relationship of the specific heats of the gas (adiabatic component); n = 1.4 f nitrogen. The equation f adiabatic change of state is used when the change in the gas volume takes place so rapidly that the temperature of the nitrogen also changes. In most cases the changes of state tend to follow the adiabatic rather than the isothermal laws. It is often the case that the charge takes place isothermally and the discharge adiabatically. Considering the equations (1) and (2), V is about 50 to 70% of the rated accumulat volume. The following fmula can act as a guideline f sizing accumulats: V 0 = x V (5) RA 50175, edition: , Bosch Rexroth Cp.

8 8 HAB Bladder-type accumulat Sizing calculations Calculation diagrams The fmula (4.1) and (4.2) are converted into diagrams on page 9 f graphic calculation purposes. Depending on the type of problem, the available oil volume, the accumulat size the pressures can be determined. Crection facts K i and K a The fmula (4.1) and (4.2) apply to ideal gases only. In practice, at pressures above 200 bar (2900 PSI), the behavi of real gases deviates markedly from that of the ideal gases. This makes it necessary to use crection facts. These are to be taken from the following diagrams. The crection facts, with which the ideal discharge volume V must be multiplied, are in the range of Adiabatic Isothermal real = real = ideal K A ideal K i K a P 2 = 200 bar K i 0.8 P 2 = 200 bar P 2 = 300 bar 0.8 P 2 = 400 bar 0.7 P 2 = 400 bar P 2 = 300 bar P 1 /P P 1 /P 2 Using the diagrams With the pre-charge pressure (p 0 ) and the minimum and maximum system pressures (p 1 and p 2 ) known, the available volume can be determined from the charts. Vertical lines are drawn from p 1 and p 2 to intersect the appropriate pre-charge curve. From the points of intersection, hizontal lines are then drawn to the left axis. Here V 1 and V 2 can be determined f the various sizes of accumulats. The difference between these values is the available volume. Similarly, pressures can be determined if the volume is known.
