The Importance Of Oil For Hydraulic Pumps If the power component hydraulic pump is compared to the heart of hydraulic equipment, then the hydraulic oil is the blood of the entire system. It not only has a close relationship with the hydraulic pump, but also has a great impact on the entire hydraulic system and equipment. In the earliest hydraulic transmission systems, hydraulic pumps used water as a working medium. Due to the low water viscosity, lubrication performance, rusting metal, and easy evaporation, it severely restricted the development of hydraulic transmission. In 1906, people began to use spindle oil and turbine oil as working medium, and in the 1950s, special hydraulic oil and hydraulic rail oil were used. These oils are specifically blended with additives and have different properties such as anti-oxidation, defoaming, anti-climbing, and improved viscosity index. With the development of high-pressure, high-flow, low-noise, and long-life hydraulic pumps, anti-wear hydraulic oils appeared in the 1960s. Reasonable selection of hydraulic pump oil can not only give full play to the performance and efficiency of the equipment, prolong the service life of the hydraulic pump and the entire hydraulic pressure, but also save the maintenance cost of the hydraulic pump. At the same time, the oil change interval of the oil itself can be prolonged, thereby effectively purchasing funds for the oil.
