How to use lubricating oil correctly in automobile sheet metal processing?

In the automobile sheet metal processing industry, the use of lubricating oil is very important, because proper lubricating oil can make the machine use longer, lubricating oil during production can help better production, but it should be noted that the use of lubricating oil and lubricating methods, because improper use not only will not play a role may play the opposite role. As a result, we will take the lubrication of automobiles as an example to show you three major misconceptions in the use of lubricants.

Add as much lubricant as you can.

The amount of oil in lubricating oil should be controlled in the middle of the oil ruler, because if there is too much lubricating oil, it may flow out of the gap between cylinder and piston. The high temperature generated by the machine will form carbon deposit. When the carbon deposit is more and more, it will form a compression ratio with the engine. The tendency of violent vibration may occur over a long period of time, and the carbon deposit will remain in place for a long time. In high temperature environment, it may ignite and cause the machinery to be burned out.

Lubricants need to be replaced when they become black

The change of color does not mean that the quality of a certain oil has changed. This understanding is unscientific. For lubricants without static decomposition agent, the change of color is indeed a deterioration, but the lubricants used in automobiles are generally added with static decomposition agent. This static agent washes the film and black coke adhering to the piston and disperses them in the oil to reduce the formation of high-temperature deposits in the engine. Therefore, the color of the lubricating oil tends to turn black after a period of time, but the oil does not completely deteriorate at this time. We need to test and analyze the quality of the lubricating oil, and then come to the conclusion that we should not operate blindly.

Lubricants are often not replaced

This understanding is incorrect. First of all, the quality of lubricating oil will be affected by some oxidation and pollution for a long time. At this time, if we only add new lubricating oil, it will be polluted by old lubricating oil. After a long time, new lubricating oil will become poor quality lubricating oil. Therefore, it is necessary to change lubricating oil frequently, especially in sheet metal processing. Pay attention to this problem.
