Hydraulic oil is an essential liquid medium in the hydraulic system. Its function is to transmit power, lubricate and protect hydraulic components. The quality of hydraulic oil directly affects the performance and reliability of the hydraulic system, so it is very necessary to understand the composition and functions of hydraulic oil.
The main components of hydraulic oil include mineral oil and chemical additives. Mineral oil is the main component of hydraulic oil, usually accounting for more than 80% of the total hydraulic oil. These mineral oils mainly come from by-products in the petroleum refining process, such as paraffin-based oils, naphthenic-based oils, etc. Chemical additives mainly include antioxidants, anti-wear agents, anti-foaming agents, etc. Their function is to improve the performance of hydraulic oil and improve the efficiency and reliability of the hydraulic system.
Hydraulic oil plays a very important role in the hydraulic system. First of all, hydraulic oil, as a medium for transmitting power, can transfer the energy of the hydraulic pump to the hydraulic cylinder or hydraulic motor to push the load to move. Secondly, hydraulic oil also plays a lubricating role, which can reduce friction and wear on the surface of hydraulic components and extend the service life of the hydraulic system. In addition, hydraulic oil also has an anti-rust effect, which can protect the surface of hydraulic components from oxidation and corrosion and maintain good working condition.
When choosing hydraulic oil, we need to comprehensively consider factors such as price, specification, and brand. First of all, price is an important consideration, and we need to choose hydraulic oil with high cost performance. Secondly, we need to select suitable hydraulic oil specifications according to the specific requirements of the hydraulic system, such as viscosity, flash point, etc. Finally, brand is also a factor that cannot be ignored. Some well-known brands of hydraulic oil have undergone strict quality control and testing, which can provide better performance and reliability guarantees.

When using hydraulic oil, we need to pay attention to the following things. First, keep the hydraulic system well ventilated to avoid deterioration and contamination of the hydraulic oil due to poor ventilation. Secondly, the hydraulic oil should be replaced regularly. It is generally recommended to replace it once every six months to a year to ensure the cleanliness and normal operation of the hydraulic system. In addition, avoid mixing different brands and types of hydraulic oil to avoid chemical reactions that may affect the performance of the hydraulic system. Finally, when replacing the hydraulic oil, thoroughly clean the tank, pipes and hydraulic components of the hydraulic system to avoid the impact of residues on the hydraulic oil and ensure the normal operation of the hydraulic system.
In short, understanding the composition of hydraulic oil and its functions is very important for the correct selection and use of hydraulic oil. When choosing hydraulic oil, we need to pay attention to factors such as price, specification, and brand. During use, we need to pay attention to things such as maintaining good ventilation and changing hydraulic oil regularly to ensure the performance and reliability of the hydraulic system.
