1 EHV Ser ies: General Infor mation ladder ccumulators Operation of the OLER gas loaded bladder accumulator is based on the considerable di erence in compressibility between a gas and a liquid, enabling a large quantity of energy to be stored in an extremely compact form. is enables a liquid under pressure to be accumulated, stored and recovered at any time. Its special design allows the bladder (the strategic component) to compress the gas and usually form into three lobes in order for the accumulator to store, then to deliver the uid under pressure, as required. e OLER gas loaded accumulator is an essential component for the optimum operation of a hydraulic circuit. In hydraulic circuits, the accumulator enables: n energy reserve which is instantaneously available to the system ompensation of pressure uctuations and spikes. Pump pulsation dampening e accumulator comprises of a pressure vessel, a rubber bladder and an anti-extrusion system. Shell material options include alloyed steel, stainless steel, aluminium, titanium and composites. Various bladder materials available which are compatible with a range of uids and temperatures. Di erent anti-extrusion systems can be used for speci c applications ( uidport assembly for high pressure, grid for low pressure, or button). Taking into account the di erent needs of various applications, Olaer proposes di erent protections external and/ or internal: are metal, nickel plating, epoxy paint, PTE, Rilsan and phenolic coating. is extensive range enables us to o er accumulators operating from 50 to +150 with pressures of up to 1500 ar and capacities of up to 575 litres. s the market leader in bladder type accumulators, Olaer has participated in the development of the EN 14359:2006 standard, which speci es the material, design, manufacturing, tests, safety devices and documentation (including the instruction manual), for pressure accumulators and gas bottles for hydraulic applications. V0 = apacity in nitrogen of the accumulator V1 = Gas volume at the minimum hydraulic pressure V2 = Gas volume at the imum hydraulic pressure V = Returned and/ or stored volume of working uid between P1 and P2 P0 = Initial preload of the accumulator P1 = Gas pressure at the minimum hydraulic pressure P2 = Gas pressure at the imum hydraulic pressure - ladder in the Pre-charge position, which means that the accumulator only contains nitrogen. e anti-extrusion system closes the hydraulic ori ce which prevents the destruction of the bladder. In low pressure accumulators the bladder rests against the grid. - Position at the minimum operating pressure. ere must be a certain amount of uid between the bladder and the hydraulic ori ce, such that the anti-extrusion system does not close the hydraulic ori ce. - Position at the imum operating pressure. e volume di erence between the minimum and imum positions of the operating pressures represents the working uid quantity. 16 Parker HanniÀn
