Lubricating oil manufacturers' lubricants are a widely used product in the automotive industry. Using them not only prolongs the service life of automobiles, but also brings convenience to our lives. But sometimes we find that the lubricant becomes hard when using it, which affects our normal use. So what is the reason for the hardening of the lubricant?

The high temperature caused by excessive use of the equipment, or the high temperature caused by other reasons, will also make the lubricant hard. For whatever reason, heat can cause excessive loss of oil from the thickener, and can accelerate the oxidation of the oil, which will make the grease in the bearing hard.

Bearings with large radii and high speeds will generate high centrifugal forces and oil separation, which will cause the product to harden.

Automobile lubricating oil is a liquid or semi-solid lubricant used in various types of automobiles to reduce friction and protect machinery and processed parts. It mainly functions as lubrication, auxiliary cooling, rust prevention, cleaning, sealing and buffering. What are the effects of automotive lubricants.

Lubrication and wear reduction

When the engine is running, if some friction parts are not properly lubricated, dry friction will occur. Practice has proved that the heat generated by dry friction in a short period of time is sufficient to melt the metal, causing damage to the machine or even jamming.

Cooling down

Only a small part of the heat generated by the combustion of fuel in the engine is used for power output and friction resistance consumption and the driving of auxiliary mechanisms; most of the remaining heat of the lubricant manufacturers will be discharged by the engine in addition to the exhaust gas to the atmosphere The cooling medium takes part.

At the end of the compression stroke, the lubricating oil manufacturer started to burn the mixture, and the cylinder pressure rose sharply. At this time, the lubricating oil in the bearing clearance will alleviate the impact load on the piston, piston pin, connecting rod, crankshaft and other components, make the engine work smoothly, prevent direct metal contact, and reduce wear.
