AI Technical Summary
Existing greases exhibit significantly reduced extreme pressure and anti-wear properties under 260℃ high-temperature conditions, failing to meet the high-temperature and high-pressure resistance requirements of hybrid drill bits and sealed mining roller cone drill bits.
The formulation of the compound multi-soap-based grease includes a high-temperature stable compound base fluid, an inert extreme pressure anti-wear additive, and a self-healing additive. The high-temperature extreme pressure wear resistance of the grease is improved by optimizing the preparation process.
In high-temperature environments of 200–260℃, the grease maintains good extreme pressure and wear resistance properties, preventing the drill bit bearings from losing their load-bearing capacity under high temperature and high pressure conditions. It is suitable for hybrid drill bits and sealed mining roller cone drill bits.
