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 the proper application of lubricating oil to the machine can make it use longer. The application of lubricating oil during production can help better production, but it should be noted that the application method and lubrication method of lubricating oil, because improper use will not work and may have the opposite effect, Let's take automobile lubrication as an example to introduce you to the three misunderstandings in the use of lubricating oil.

Add as much lubricant as you can

The amount of lubricating oil should be controlled in the middle of the oil dipstick, because if there is too much lubricating oil, it may flow out of the gap between the cylinder and the piston, and carbon deposits will be formed through the high temperature emitted by the machine. When these carbon deposits are more and more, they will form a compression ratio with the engine. After a long time, they may have a tendency to vibrate violently, and these carbon deposits may be ignited in a high temperature environment for a long time, Cause the machine to burn out.

The lubricating oil needs to be replaced when it turns black

The change of color does not mean that the quality of a certain oil has changed. This understanding is unscientific. For lubricants without detergent, the blackening of color is indeed a sign of deterioration, but lubricants used in automobiles are generally added with detergent. This kind of tranquilizer washes the rubber film and black carbon deposit adhered to the piston and disperses them in the oil to reduce the generation of high-temperature sediment of the engine. Therefore, the color of the lubricating oil is easy to turn black after being used for a period of time, but the oil is not completely deteriorated at this time. We need to test and analyze the quality of the lubricating oil, and then draw a conclusion. Do not operate blindly.

The lubricating oil does not need to be changed frequently

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