Product description

Notes
Обозначение CE за мембранни хидроакумулатори >1,0 л обем на газ
Работно налягане от 100 до 350 бара, минималното работно налягане трябва да е с 10 % по-високо от налягането на пълнене с газ
максимално налягане на пълнене с газ 130 бара
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
Хидроакумулаторите се доставят от склада не напълнени. За пълнеж N2 по желание на клиента се начисляват допълнителни разходи.
