During the operation of mechanical equipment, friction generates a large amount of heat. Without the protection of lubricating oil, friction between mechanical parts can lead to increased wear and even damage to the equipment. The main function of lubricating oil is to form a lubricating film between mechanical parts, reducing friction and reducing wear. By using lubricants, it is possible to effectively extend the service life of mechanical equipment, reduce the frequency of maintenance and replacement of parts, and save maintenance costs.

Another important role of lubricants is to improve the efficiency of mechanical equipment. Lubricants can reduce frictional resistance between mechanical parts, making mechanical equipment operate more smoothly. Compared to using no lubricant, using lubricant can reduce energy consumption and improve work efficiency. According to statistics, the use of lubricants can reduce the energy consumption of mechanical equipment by more than 10 %, greatly saving energy resources.

During use, lubricating oil will gradually age and produce harmful substances. If the lubricating oil is not replaced in time, these harmful substances will pollute the environment. Regular replacement of lubricating oil is very important. Choosing high-quality lubricants can also reduce the production of harmful substances and protect the environment.

The role of lubricants in mechanical equipment cannot be underestimated, as they can reduce wear and tear, extend service life, improve work efficiency, reduce energy consumption, and protect the environment. When using mechanical equipment, we should pay attention to replacing the lubricating oil regularly and choose high-quality lubricating oil. Only in this way can we better protect mechanical equipment, extend its service life, and contribute to environmental protection.
