No matter what machine it is, it will be destroyed due to friction, which requires the use of lubricating oil to reduce friction. The purpose of lubrication is to maintain the equipment to increase the service life and reduce the repair rate. Lubrication has four functions for water well drilling tools. Today I will give you a detailed introduction:

　　1. Reduce friction: This is the main function of lubrication, avoiding direct contact with the metal surface of the transmission system parts, thereby reducing friction resistance and reducing wear consumption.

　　2. Cooling and heat dissipation: In high-speed rotating components, a lot of heat will be generated due to friction. If you don't try to dissipate the heat, it will heat up again and damage the parts.

　　3. Anti-rust protection: water well drilling tools are often exposed to the sun and rain when working outdoors, and the product is easy to rust. If you apply good lubricating oil on the surface, you can avoid rust and increase the service life.

　　4. Sealing blockage: The sealing packing and the end cover of the rolling bearing are equipped with wool felt, which is reasonably sealed and dustproof because of the oil immersion.
