ISO 5596:1999 pdf free.Hydraulic fluid power — Gas-loaded accumulators with separator — Ranges of pressures and volumes and characteristic quantities.
Introduction of ISO 5596:
In hydraulic fluid power systems, power is transmitted and controlled through a liquid under pressure within an enclosed circuit.
Gas-loaded accumulators are components that are able to store and return energy in accordance with the principle of compressibility of gases.
ISO 5596 specifies the characteristic performance quantities required for defining, designing, and testing gas-loaded accumulators with separator, which are used in hydraulic fluid power systems.
It also defines ranges of pressures and volumes for these accumulators.
4 Applications
4.1 Energy storage
The gas-loaded accumulator stores hydraulic fluid under pressure during a period of low energy demand from the circuit in which it is mounted. The stored hydraulic fluid is then returned to the circuit to supplement or replace the pump discharge temporarily or to ensure emergency operation.
4.2 Pulse or surge damping
The gas-loaded accumulator absorbs hydraulic fluid to reduce pressure peaks and returns hydraulic fluid to compensate for pressure drops. The accumulator thus reduces the amplitude of pressure oscillations in the circuit in which it is mounted.
4.3 Thermal compensation
The gas-loaded accumulator absorbs volume changes resulting from changes in the temperature of the hydraulic fluid contained in an isolated part of the circuit.
6 Ranges of pressures and volumes
6.1 Nominal pressure range, P4
6,3 (63)— 10(100)— 16 (160)—20 (200)—25 (250)—31,5 (315) —40 (400)—50 (500)—63 (630)
Pressures are expressed in megapascals, with the equivalent value in bars in parentheses.
For special applications that require lower or higher pressures, use pressures corresponding to the R 10 series of preferred numbers (see ISO 3).
6.2 Nominal volume range, V
0,25—0,4—0,5–0,63—1,0—1,6—2,5—4,0—6,3—10—16—20—25—32—40—50—63—100—160—200
Volumes are expressed in litres.
For special applications that require smaller or larger volumes, use volumes corresponding to the A 10 series of preferred numbers (see ISO 3).
