P1V1n = P3V3n = P2V2nV3Gas Volume at P3V2Gas Volume at P2V1Gas Volume at P1Volume calculation formulas will change depending on the application. For applications, please refer to page 10.For dynaclean calculation, please refer to page 123, Dynaclean.For other application calculations, please contact us.The accumulator charges and discharges the fluid by the compression and expansion of gas.Gas volume calculation is calculated basically by Boyle's law, which shows the relationship between pressure and volume of gas.● Basic Calculation TermsMaximum Working PressureMaximum pressure of the hydraulic pressure sourceMaximum pressure accumulated in the accumulatorMinimum Working PressureMinimum pressure required to run the actuatorMinimum pressure to be discharged from the accumulatorGas Charging PressureThe pressure of nitrogen gas contained within the bladderRequired Oil Volume To Be Discharged From (Charged In) AccumulatorV2 minus V3 difference is the oil volume discharged from (charged in) the accumulator.Polytropic ExponentGas is affected by the heat in the compression and expansion.The actual gas change is called the polytropic change, and in calculation it is used as the polytropic exponent.* For the pressure to be used in the calculation, convert to absolute pressure. Absolute pressure (MPa · abs) = Gauge pressure (MPa · G) + 0.1013(MPa・abs)(MPa・abs)(MPa・abs)(L)(L)(L)(L)Nitrogen gas compressionNitrogen gasFluidFluidNitrogen gas expansionFluid19nP3P2P1VwApplicationEnergy ConservationEmergency OperationLeakage CompensationTemperature CompensationCounterbalanceShock AbsorberPulsation DampeningShock-absorbingOil tank dustproofCalculation FormulaEnergy Storage (1-3-1)Pulsation Dampening (1-3-2)Shock-absorbing (1-3-3)Dynaclean1.
