Research on mixing and testing VG 22 hydraulic oil for use in military technical vehicles

Abstract

The paper presents the results of research on the formulation and performance evaluation of VKX.AU hydraulic oil with a viscosity grade of VG 22, developed based on an improved formulation aimed at enhancing transmission efficiency and equipment reliability under specific military operating conditions. The product was blended from high-quality refined base oils combined with a specialized additive package, including a pour point depressant, antioxidant, anti-wear agent, and rust inhibitor, ensuring physicochemical stability and long-term durability. Test results show that the formulated VKX.AU hydraulic oil meets the quality standards equivalent to the imported product specified in TU 38.1011232–89, with several superior properties such as enhanced anti-wear, anti-rust, and demulsifying performance. In addition, the blended oil demonstrated good compatibility with sealing materials used in the hydraulic system of the 105 mm artillery.
