Product description

Notes
CE oznaka za membranski spremnik > 1,0 l volumen plina
Radni tlak 100 do 350 bar; min. radni tlak mora biti 10 % iznad tlaka punjenja plina
max tlak punjenja plinom 130 bara
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
Spremnici tlaka isporučuju se iz skladišta nenapunjeni. Za punjenje N2 po želji kupca nastaju zasebni troškovi.
