Hydraulic is basically a subject dealing with the mechanical properties of liquids while hydraulic machines are the tools that enable fluid power to do work. Hydraulics is used for the generation, control and transmission of power through the use of pressurizing liquids also called hydraulic fluid. Hydraulic fluids, also called hydraulic liquids, are the medium by which power is transferred in hydraulic machinery. Common hydraulic fluids are based on mineral oil or water.Examples of equipment that might use hydraulic fluids include excavators, brakes, power steering systems, transmissions, backhoes, garbage trucks, aircraft flight control systems and industrial machinery. Mineral oil or liquid petroleum is a by-product in the distillation of petroleum to produce gasoline and other petroleum based products from crude oil. It is a transparent, colorless oil composed mainly of alkanes (typically 15 to 40 carbons) and cyclic paraffins, related to white petrolatum. It has a density of around 0.8 g/cm3. Mineral oil is a substance of relatively low value, and it is produced in very large quantities. Mineral oil is available in light and heavy grades, and can often be found in drug stores. In the late 1800s, the term "mineral oil" or "rock oil" was first used to describe the petroleum hydrocarbons and associated products that were produced from wells that tapped underground reservoirs. The term differentiated petroleum hydrocarbons produced from underground sources from other common oil sources at the time such as "palm" oil or "whale" oil. In today's petroleum exploration and production (e&p) business, the phrase "mineral oil" is most often used in legal documents to define and encompass all of the liquid hydrocarbon and gaseous products produced from wells drilled into underground petroleum-bearing reservoirs. There are three basic classes of refined mineral oils: paraffinic oils, based on n-alkanes, naphthenic oils, based on cycloalkanes, aromatic oils, based on aromatic hydrocarbons. Mineral oil is used in a variety of industrial/mechanical capacities as a non-conductive lubricant. Refined mineral oil is used as transformer oil. Electric space heaters sometimes use it as heat transfer oil, and it can be used generically as a coolant in electric components as it does not conduct electricity. Because it does not absorb water from the air, mineral oil can be used as an automotive, aviation, and bicycle brake fluid. There have been many liquids tested for use in hydraulic systems. Currently, liquids being used include mineral oil, water, phosphate ester, water-based ethylene glycol compounds, and silicone fluids. The three most common types of hydraulic liquids are petroleum-based, synthetic fire-resistant and water-based fire-resistant.
