Gängige Hydraulikflüssigkeiten
Hydraulikarmaturen werden verwendet, um das Hydrauliköl oder die Hydraulikflüssigkeit innerhalb des Systems abzudichten. Daher sollten die Fittings mit dem verwendeten Fluid kompatibel sein. Hydraulikflüssigkeit liefert die Energie an das System, damit die Maschine ihre Arbeit verrichten kann. Es gibt verschiedene Arten von Hydraulikmedien auf dem Markt.
Flüssigkeiten auf Erdöl-basis: Petroleum or mineral-based fluid is the most used hydraulic fluid. Additives in such fluids provide protection from rust and oxidation, wear and tear, corrosion, and extreme pressure. These fluids are generally high quality, low cost, and widely available.
Flüssigkeiten auf Wasser-basis: These fluids have high water content, so, they are used for fire-resistance. They are available as water-in-oil emulsions, oil-in-water emulsions, and water-glycol blends. They are more expensive than petroleum-based fluids and have lower wear resistance.
Flüssigkeiten auf synthetischer -Basis: These fluids are man-made and provide advantages like fire-resistance, lower friction, and thermal stability. They are ideal to use in high-temperature and high-pressure applications due to their excellent lubricating property. However, they are more expensive than petroleum-based fluids and maybe slightly toxic.
