Ortak hidrolik sıvılar
Hidrolik bağlantı elemanları, sistem içindeki hidrolik yağı veya sıvıyı sızdırmaz hale getirmek için kullanılır. Bu nedenle, bağlantı elemanları kullanılan sıvı ile uyumlu olmalıdır. Hidrolik sıvı, makinenin işini yapmasına izin veren sisteme enerji sağlar. Piyasada farklı tipte hidrolik ortamlar bulunmaktadır.
Petrol-bazlı sıvılar: 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.
Su-bazlı sıvılar: 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.
Sentetik-tabanlı sıvılar: 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.
