Relying on China's core lubricating oil manufacturing technology, integrating optimization for heavy-load gear working conditions of petroleum exploitation and supporting equipment, and adopting internationally advanced additive formulas, we create high-quality heavy-load industrial gear oil suitable for global petroleum exploitation. The core technical highlights are as follows to ensure leading product performance and strong adaptability: High-Quality Base Oil Refining and Synthetic Technology: Ordinary types adopt hydrocracked base oil, which is refined through multiple precision processes to remove impurities, sulfur, nitrogen and other harmful substances, with high purity and stable viscosity index; low-temperature synthetic types adopt PAO synthetic base oil, which has excellent low-temperature fluidity and high-temperature oxidation resistance, laying a solid foundation for the core performance of gear oil. High-Efficiency Extreme Pressure and Anti-Wear Additive Formula Technology: Adopting sulfur-phosphorus composite extreme pressure and anti-wear additives, scientifically proportioned, it can quickly form a high-strength extreme pressure lubricating film under heavy-load and high-impact working conditions, effectively resisting tooth surface scuffing, pitting and wear, adapting to the continuous operation needs of heavy-load equipment such as petroleum drilling rig gearboxes, and reducing the equipment failure rate. Temperature Resistance, Anti-Aging and Low-Temperature Anti-Freezing Technology: Adding high-efficiency antioxidants and anti-aging agents to inhibit the oxidation reaction of gear oil at high temperatures, avoiding oil carbonization and thickening, and extending the service life of the oil; for severe cold working conditions in Russia, adding special low-temperature anti-freezing agents and fluidity improvers to optimize low-temperature fluidity, reduce the pour point to below -40℃, and ensure normal startup in extremely cold environments. Anti-Pollution and Anti-Emulsification Technology: Adopting composite detergent dispersants and anti-emulsifiers, which can quickly separate water, sand and other impurities mixed into the oil, prevent oil emulsification and deterioration, and keep the gear oil clean; at the same time, it improves the filterability of the oil, reduces the wear of the gear tooth surface by impurities, extends the service life of gears and equipment, and reduces operation and maintenance costs. Customized Formula Technology: According to the working condition differences of the Middle East, Russia and Tanzania, customized formulas are developed - the Middle East version strengthens high-temperature anti-thickening and anti-sand performance, the Russian version strengthens low-temperature anti-freezing and fluidity, and the Tanzania version strengthens water resistance, anti-pollution and cost performance, realizing precise adaptation of "one formula per region" and meeting the differentiated needs of different markets.
