Product description

Notes
CE-mark for diaphragm accumulators > 1.0 l gas volume
Working pressure 100 to 350 bar; min. working pressure must be 10% above gas charge pressure
Max. gas filling pressure 130 bar
To protect the diaphragm, the reservoir should never be completely emptied on the oil side.
Description
Da Flüssigkeiten praktisch inkompressibel sind, wird in hydraulischen Druckspeichern die Kompressibilität eines Gases (hier Stickstoff) zur Speicherung von Energie verwendet.
Ein hydraulischer Druckspeicher besteht aus zwei Kammern (Flüssigkeitsseite und Gasseite), welche durch ein flexibles, gasdichtes Element getrennt sind. Die Flüssigkeitsseite ist mit dem hydraulischen Kreislauf der Anlage verbunden. Bei einem Druckanstieg in der Anlage wird der Speicher mit Öl gefüllt und das Gas komprimiert. Bei einem Druckabfall wird die gespeicherte Druckflüssigkeit durch Expansion des komprimierten Gases in den Kreislauf zurückgedrängt.
Ordering information
Pressure accumulators are available uncharged ex-warehouse. Additional costs apply upon customer request for N2-charging.
If required, please include counter nut HK MS M33 - 15 in your order.
