määrdeõlides

Määrdeõlid are lubricating oils used in various mechanical applications. Their primary function is to reduce friction and wear between moving surfaces. This is achieved by forming a thin film of oil that separates the components, preventing direct contact and thus minimizing damage.

The composition of määrdeõlid can vary significantly depending on the intended use. They are typically derived from petroleum, synthetic base stocks, or vegetable oils. Additives are often incorporated to enhance specific properties, such as extreme pressure resistance, oxidation stability, viscosity control, and corrosion inhibition. These additives are crucial for ensuring the lubricant performs effectively under demanding conditions.

Common applications for määrdeõlid include internal combustion engines, gearboxes, hydraulic systems, turbines, and industrial machinery. In engines, they lubricate pistons, crankshafts, and other moving parts while also helping to cool the engine and clean away combustion byproducts. In industrial settings, they ensure the smooth operation of complex machinery, extending the lifespan of critical components. The selection of the appropriate määrdeõli is vital and depends on factors like operating temperature, pressure, speed, and the materials of the surfaces being lubricated. Proper maintenance and regular oil changes are also essential for maintaining the effectiveness of these lubricants.
