Four Functions of Lubrication for Water Well Drilling Rig
- Reducing friction: The main function of oil lubrication, preventing direct metal contact to reduce friction resistance and wear loss
- Cooling and heat dissipation: Disperses heat from high-speed rotating parts to prevent temperature buildup and part burning
- Rust prevention: Grease application prolongs service life of metal parts exposed to rain and prevents rust
- Sealing blockage: Oil-immersed wool felt in sealing packing and bearing end covers effectively seals and prevents dust
