Product description

Notes
Marcação CE para acumulador de membrana > 1,0 l volume de gás
Pressão operacional 100 até 350 bar / pressão operacional mín. deve ficar 10 % acima da pressão de enchimento de gás
Pressão máxima de enchimento de gás 130 bar
Para proteger o diafragma, o acumulador nunca deve ser totalmente drenado no lado do óleo.
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
Os acumuladores são fornecidos de stock sem enchimento. O enchimento N2 a pedido do cliente tem custos adicionais.
