Bežné hydraulické kvapaliny
Hydraulické armatúry sa používajú na utesnenie hydraulického oleja alebo kvapaliny v systéme. Preto by armatúry mali byť kompatibilné s použitou kvapalinou. Hydraulická kvapalina dodáva energiu systému a umožňuje stroju vykonávať svoju prácu. Na trhu sú rôzne typy hydraulických médií.
Kvapaliny na{0}}ropnej báze: 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.
Tekutiny na-vodnej báze: 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.
Kvapaliny na báze syntetických{0}}základov: 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.
