As the liquid is pressurized, the hydraulic accumulators are treated like pressure vessel and must be designed for the max. operating overpressure considering the acceptance standards of the country of installation. In most hydraulic systems, hydro-pneumatic (gas-charged) accumulators with separator element are used. The difference between bladder, piston and diaphragm type accumulators lies in the type of separator element. Hydraulic accumulators essentially consist of a fluid section and a gas section with a gas-tight separator element. The fluid section has a connection to the hydraulic circuit. During the pressure increase, the gas is compressed and liquid accepted in the hydraulic accumulator. When the pressure decreases, the compressed gas expands and displaces the accumulated fluid into the circuit. Diaphragm type accumulator Diaphragm type accumulators consist of a pressure-resistant steel vessel (1) which most commonly has a spherical to cylindrical form. Inside the accumulator, there is the separator element, namely a diaphragm (2) made of an elastic, flexible material (elastomer) with the closing button (3) and the plug screw (4). They correspond to directive 97/23/EC.
