What is a lubricant and important points about them

A lubricant is a substance that is used to reduce the amount of friction between moving and fixed surfaces, such as oils Grace and etc. If we want to define psychoanalysis in a simple way, it is called a method that is used to prevent friction and wear of moving surfaces that are placed on top of each other. What is expected from a psychoanalyzer is that, in addition to reducing friction and ease of movement of machine parts, it is possible to reduce Energy consumption should also protect against corrosion, wear and rust. In general, its most important tasks are: preventing stress and impact, moving pollutants, transmitting hydraulic power, and sealing moving parts.   \ n

Types of lubricants models

Lubricants are generally divided into two major categories, automotive and industrial, which has its own industry sub-branch, which is classified into three major categories of oils and greases and special models, of course these materials It can also be divided in terms of state, if we want to tell you about them in terms of state, we must mention four categories of gas, liquid, grease, and solid, each of which has a series of characteristics that we would like to explain to you.

Liquid lubricants

Liquid lubricants are the first category of psychoanalysts that we want to introduce to you. In the following, there are a series of tips and steps about them. First of all, you should know that the most important of them are oils, which themselves are divided into two large categories of synthetic and mineral oils. These models are the most common and most used models of lubricants. Both of them are considered to be a kind of petroleum derivatives, with the difference that edible mineral oils perform a series of operations on crude oil and a chemical reaction is produced, while a more controlled chemical reaction is used to produce synthetic oil, which is why the price of synthetic oils is higher than mineral oils. It is higher and in general, mineral oils are produced more than synthetic oils due to the many uses they have in the production of these materials, of course, the capabilities of synthetic oils are much higher than a mineral base oil due to the special reactions that are carried out on them, because perfectly suitable oils synthetically produced and cannot be extracted in education, of course, except for synthetic oils and oils whose main source is crude oil, there is also another type of oil that is obtained from animals, fish and plants, which is called natural oils. The use of these oils as psychoanalysts has been widely used in the past. but currently crude oil is the main source of their production, one of the characteristics of natural oils is biological decomposition and their effects, and in this respect they are better than synthetic and mineral oils, but they cannot be stored for a long time and their production cost is also is high.

Gas lubrication

Gas lubrication is like air and helium liquid vapor, which has very high or low speed in cases of very high or low temperatures and in materials where nuclear radiation are used. One of the most important characteristics about them is that their viscosity does not change with temperature change, therefore they are considered powerful materials that are used in a large part of the industry. In addition, since gases are light liquids, their weight can be ignored. This issue causes their flow to remain uniform and simple at very high speeds, this river is used in bearings at very high speeds, and gas banks have low friction, they do not have impurities, and they do not overflow, so they are used in the food and pharmaceutical industries.
