Product description

Notes
Marchio CE-per accumulatore a membrana > 1,0 l volume del gas
Pressione d'esercizio da 100 a 350 bar; min. Pressione d'esercizio deve essere il 10 % maggiore della pressione di riempimento gas
Max. gas filling pressure 130 bar
To protect the diaphragm, the reservoir should never be completely emptied on the oil side.
Description
As liquids are practically incompressible, the compressibility of a gas (in this case nitrogen) is used in hydraulic accumulators to store energy.
A hydraulic accumulator consists of two chambers (liquid side and gas side), which are separated by a flexible, gas-tight element. The liquid side is connected to the hydraulic circuit of the system. When the pressure in the system rises, the accumulator is filled with oil and the gas is compressed. If the pressure drops, the stored pressurised liquid is forced back into the circuit by expansion of the compressed gas.
Ordering information
Gli accumulatori vengono forniti vuoti dal magazzino. Per un riempimento N2 su richiesta del cliente sono previsti costi a parte.
