Lubrication is the act and consequence of lubricating . East verb (lubricate), meanwhile, refers to the application of a substance to minimize friction that occurs when different elements come into contact .
Lubrication is very important in the field of mechanics . When there are two moving parts, the use of a lubricant facilitates the movement of the gear and reduces deterioration.
The lubricant must not be degraded and must have resistance to Pressure and at high temperatures. Lubrication can be achieved with liquid products (of greater or lesser viscosity) or with solid products. As for its origin, the lubricants are divided into synthetic , vegetables or minerals .
The internal combustion engines , like those used in cars, require lubrication. The vehicles In this framework, they have a lubrication system that reduces the wear of the different engine parts. A synthetic oil or mineral oil can be used as a lubricant.
In order for the engine to function properly and not be damaged, it is therefore essential to ensure its lubrication. That is why the level of oil of the car and replace said lubricant every certain amount of kilometers traveled to guarantee its effectiveness.
It is important to note that some phenomena are also considered forms of lubrication even if the human being intervenes in their developing . In the field of motorized transport, for example, the so-called aquaplaning Between a car and the road.
The phenomenon called aquaplaning, hydroplane or aquaplane It is a case in which a vehicle passes on a road covered with water at a certain speed and loses traction, in addition to the driver not control it Correctly. When this occurs on all wheels, the car acts as a sled impossible to control.
It is necessary to establish a difference between aquaplaning and a situation in which the water causes the lubrication of the friction between the vehicles and the pavement, something that happens after a slight precipitation, for example.
The vaginal lubrication , on the other hand, it is generated from flow It secretes the vagina. This lubrication helps the development of intercourse and protects the female sexual organ from infections .
If the vagina is not properly lubricated, the woman You may feel discomfort and pain during sex. The lack of lubrication also increases the risk of infection.
In short, lubrication causes a change in the relationship established between the two objects. If the lubricant was not applied, they would rub in a violent or harmful way for both. However, the presence of this substance results in a loss of space for them, however small: the lubricant film has a thickness that can not occupy the objects, and this can generate a slight widening of the system .
The science that is responsible for the study of lubrication is called tribology . It also includes friction and wear , since they are phenomena that are closely linked to lubrication.
The study of tribology focuses on solid surfaces that are in motion, where we can encompass the situations mentioned in the previous paragraphs, such as the advance of a vehicle on a road or the rubbing of the internal components of a machine .
The fields of knowledge necessary to understand these phenomena they are the technology of materials, physics and chemistry. In spite of them, even without any technical concept we can easily appreciate the differences that lubrication brings to a system, and the damages of not using it.
