The great wall's super-low-temperature hydraulic fluids, combined with high-composite viscosity indices of deep precision with hydrogen base oils and a selection of a variety of functional additives, have been combined with international technology-level production processes, and the product is better at the low-temperature performance than hv low-temperature hydraulic fluids, especially for off-site machinery in harsh winter areas. This product is divided into 32 and 46 plates according to their 40°c kinetic viscosity. Great wall lubricant l-h s ultra-low-temperature hydraulic fluid
Performance characteristics
• full substitution of hm, hv and imported low-temperature hydraulic oil products abroad at higher value
• high- and low-temperature performance, with low-temperature start-up, low-temperature mobility and high-temperature protection, compared to hm and hvs, effectively prolongs the useful life of the oil
• excellence in viscerality, shearing stability, oxidation, and small changes in viscosity, making hydraulic system work more stable
• excellence in grinding and rust resistance, preservation and effective protection of equipment
• good foam resistance, air release and emulsion
Adaptation of excellent seals to prevent leakage of oil。
