Basic Principles of Lubricating Oil
The history of human use of lubricating oil can be traced back to the early days of human civilization, but its true significance began in the 18th century when the world's first lubricating oil factory was established in Balakan, Russia, introducing the world's first drop of mineral-based lubricating oil. With technological advancements, modern lubricating oils are now widely available, meeting the needs of people's production and daily life.
Fundamental principles of lubricating oil
The fundamental principles of lubricating oil are friction, wear, and lubrication. When two contacting surfaces move relative to each other, friction and wear occur. Lubrication is the method to reduce friction and wear.
The losses caused by friction and wear are significant. In terms of friction alone, about half of the world's energy is consumed. Simply by using lubricating oil to reduce friction, the transportation, power generation, machinery, and steam turbine industries alone can save 10% of energy. One can imagine the immeasurable losses caused by wear.
Therefore, lubrication involves adding a lubricant between relatively moving surfaces to reduce frictional resistance, save energy, and reduce surface wear. It also extends the service life of equipment. For example, in the cutting industry, using suitable cutting oil can effectively improve cutting process quality and protect the cutting tools.
In the 1960s, the British scientist Jost formally proposed defining friction, wear, and lubrication as tribology, marking the beginning of formal research in this field.
Therefore, a correct understanding of friction, wear, and lubrication is crucial for the proper use of lubricating oils.
