What is lubricating oil and what is the definition of lubricating oil

Lubricating oil is made from base oil and additives in strict proportions. The main additives are: anti-wear agents, antioxidants, cleaning and dispersing agents, etc.

The type of lubricant.

1 Automotive lubricants.

2 Industrial lubricants.

Machinery oil (high-speed lubricating oil), loom oil, spindle oil, rail oil, rolling oil, gas turbine oil, compressor oil, refrigeration oil, cylinder oil, marine oil, gear oil, pressure gear oil, axle oil, instrument oil, vacuum pump oil.

I want to say that this lubricating oil additive really does not need to add, a bit of a snake to add a feeling, I have used it a few times before, there is no effect, it is better to change the high-quality engine oil to the real, now it is the use of G T magic red engine oil, the base oil of the four types of PAO has good high temperature resistance and anti-recession ability, long-term maintenance, and the addition of esters, the power burst is enough, the driving experience is much better than the previous oil, the oil is durable for 15,000 kilometers, and the maintenance is more cost-effective than before.

Additives have been used before, the effect is not very obvious, a small stick to dozens of hundreds, I feel that the cost performance is not very high, now are using G T magic red oil, four types of PAO base oil long-lasting and durable, as well as the addition of esters, the power burst is enough, the driving experience is much better than the previous oil, the oil is 15,000 kilometers a change, maintenance is not more cost-effective than using additives?

1.Adhesion is different: when the friction part is at rest, the grease retains its original shape and does not automatically lose due to gravity, nor does it slip on the vertical surface and drip out of the gap.

This feature is ideal for friction areas that often stop, start, or do not start, where it is difficult to replenish grease materials (such as those of overhead cranes), and where openings or seals are poor.

2.Different temperature ranges: Greases operate over a wider temperature range than oils.

For example, a typical lithium-based grease can be used in the temperature range of -20 120, and a general calcium-based or lithium-based grease can also be used in a temperature range of -20 60 or -20 120. The temperature range of a certain brand of lubricant is much narrower.

3.Different pressure resistance: the adsorption capacity of grease on the metal surface is much greater than that of lubricating oil, which can form a relatively strong oil film and bear relatively high working loads.

This is the result of the high number of polar substances in the oils and fats. In addition, as a base grease, when polar additives are added, the susceptibility is better than that of lubricating oil.

Different classifications: lubricants are divided into paraffin-based, intermediate-based, and naphthenic base oils.

Lubricants are divided into oily liquid lubricants, greasy semi-solid greases, and solid lubricants. Different functions: lubricating oil mainly plays the role of lubrication, auxiliary cooling, rust prevention, cleaning, sealing and buffering, etc., and lubricant is a lubricating medium used to reduce the frictional resistance of the friction pair and slow down its wear.

Different characteristics: Lubricant is a lubricating product based on grease, while lubricant is water-soluble. <

Explanation of lubricating oil (1) [lubricating oil] oil used as a lubricant (such as petroleum distillation or fatty oil) (2) [lubricant] This type of substance placed between the moving parts of machinery. Also known as grease explains in detail the oily liquid that is applied to the surface of moving parts such as machine bearings. There are celebrations to reduce friction, avoid heat, and prevent machine wear.

It is generally the product of fractionated petroleum, but it is also refined from animal and vegetable oils. It is also called lubricating oil. Word decomposition Explanation of moist run (runpeisun) ù not dry, moderately wet and dry:

3. Network Explanation.

Lubricating oil (mechanical engineering term) Lubricating oil is a liquid or semi-solid lubricant used in various types of automobiles and mechanical equipment to reduce friction and protect machinery and processed parts, mainly playing the role of lubrication, auxiliary cooling, rust prevention, cleaning, sealing and cushioning (ROAB). As long as it is applied between two objects in relative motion, and can reduce the friction and wear caused by the contact between two objects, it is lubricating oil.
