How much do lubricants function?

Lubrication is the use of a lubricant to reduce (or control) friction or other forms of surface-destroying action between two friction surfaces, thereby reducing friction. As two different surfaces come into contact, they rub against each other and have the following consequences: wear, noise, high temperatures. This can be reduced if we add a lubricant between the two. Lubricant is also one of the lubricants, which creates a film of oil on the surface of the machine. The lubricant is also one of the lubricants, which creates a film of oil on the surface of the parts, and between the two parts in contact with each other. This makes activities between the two easier, smoother and faster, and greatly reduces the damage caused by friction; therefore, it is important to choose the right lubricant if you want your engine to achieve optimal lubrication.

What is the main function of the lubricant?

(1) Control friction: adding lubricant between friction surfaces to form a lubricating film, reducing direct metal contact between friction surfaces, thus reducing the coefficient of friction, reducing frictional resistance and reducing power consumption.

(2) Reduce wear and tear: friction between the surface with a certain strength of the lubricating film, can support the load, to avoid or reduce the direct contact of the metal surface, which can reduce the contact surface of the plastic deformation, melting and welding, shortening and then bonding and other degrees of adhesion wear.

(3) cooling: lubricants can reduce the coefficient of friction, reduce frictional heat generation.

(4) sealing isolation: lubricants, especially grease covering the friction surface or other metal surfaces. Can isolate water, moisture and other harmful substances and metal contact, thereby reducing corrosion and wear, prevent rust, protect the metal surface.

(5) reduce vibration: lubricants can shock vibration of mechanical energy into hydraulic energy, play a role in slowing down the impact, noise absorption.
