[0002] Lubrication is an important part of tribology research. It is a technical measure to improve the friction state of the friction pair to reduce friction resistance and slow down wear. Lubrication is generally achieved through lubricants. Making full use of modern lubrication technology can significantly improve the performance and life of the machine and reduce energy consumption.

[0003] The lubricator is a device used to control the delivery and distribution of lubricating oil.
