Almindelige hydraulikvæsker
Hydrauliske fittings bruges til at forsegle den hydrauliske olie eller væske i systemet. Beslagene bør således være kompatible med den anvendte væske. Hydraulikvæske leverer energien til systemet, så maskinen kan udføre sit arbejde. Der findes forskellige typer hydrauliske medier på markedet.
Petroleums-baserede væsker: 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.
Vand-baserede væsker: 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.
Syntetisk-baserede væsker: 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.
