For enterprises engaged in mechanized construction, the technical condition of construction machinery is a direct factor determining whether normal operations can be maintained. For machinery utilizing hydraulic transmission, the proper functioning of the hydraulic system is a key indicator of its overall technical health. High-quality hydraulic fluid ensures the reliable operation of the hydraulic system, while proper maintenance is fundamental to that reliability.
Hydraulic fluid serves to transmit pressure and provide lubrication, cooling, and sealing within the system; improper selection of fluid is a primary cause of premature failure and reduced durability. Hydraulic fluid should be selected according to the specifications in the equipment's operation manual. If a substitute fluid must be used due to special circumstances, it should match the performance characteristics of the original specified fluid as closely as possible. Different brands or grades of hydraulic fluid must not be mixed, as this can trigger chemical reactions and alter fluid properties. Hydraulic fluid that is dark brown, milky white, or has an unusual odor indicates deterioration and must not be used.
