Märkävoitelussa

Märkävoitelussa, meaning "wet lubrication" in Finnish, refers to a lubrication method where a liquid lubricant is applied to a surface or component. This technique is used in various applications to reduce friction, wear, and heat between moving parts. The lubricant can be oil-based, water-based, or synthetic, chosen based on the specific operating conditions and materials involved.

In wet lubrication systems, the lubricant is often circulated or continuously supplied to the contact area. This can be achieved through methods like oil baths, splash lubrication, or forced circulation systems. The presence of a liquid film between the surfaces prevents direct metal-to-metal contact, thereby minimizing abrasive wear and extending the lifespan of the components. This method is particularly effective in high-speed or high-load applications where friction can generate significant heat.

Common examples of wet lubrication include the engine oil system in vehicles, which lubricates the crankshaft, pistons, and other internal components. It is also used in gearboxes, bearings, and hydraulic systems. The effectiveness of wet lubrication depends on factors such as lubricant viscosity, temperature, pressure, and the cleanliness of the system. Contamination of the lubricant can reduce its effectiveness and potentially cause damage. Regular maintenance and lubricant changes are crucial for optimal performance and longevity of the lubricated components.
