How does anti-wear hydraulic oil play an anti-wear role?
Publish Time: 2025-01-09
Anti-wear hydraulic oil, as an important component of the hydraulic system, has multiple functions, among which the most critical is its anti-wear performance. This feature is of great significance for protecting the metal parts inside the hydraulic system, reducing wear, improving system efficiency and extending service life.
First of all, the base oil of anti-wear hydraulic oil usually uses high-quality mineral oil or synthetic oil, which itself has certain lubricating properties. However, the base oil alone is not enough to meet the complex and changing working conditions. Therefore, a variety of high-performance additives are added to anti-wear hydraulic oil, among which the most critical is anti-wear agent.
Anti-wear agent is a special chemical substance that can form a protective film on the metal surface. This protective film can effectively isolate the direct contact between metal parts, thereby reducing friction and wear. The formation mechanism of this protective film involves a variety of complex chemical reactions and physical adsorption processes. Under boundary lubrication conditions, anti-wear agent molecules can form a boundary film with different properties from the medium at the metal friction interface. This boundary film has low shear strength and good anti-wear performance, which can effectively prevent direct contact and wear between metals.
In addition, anti-wear hydraulic oil also contains antioxidants, anti-corrosion agents, anti-foaming agents and other additives, which can further improve the stability and service life of hydraulic oil. Antioxidants can prevent hydraulic oil from oxidative decomposition at high temperatures, generating harmful oxides and acidic substances, thereby maintaining the cleanliness and lubrication performance of hydraulic oil. Anti-corrosion agents can prevent hydraulic oil from corroding metal parts and protect the integrity of the system. Anti-foaming agents can reduce the generation of bubbles in hydraulic oil and improve the static pressure transmission efficiency and stability of the system.
In summary, anti-wear hydraulic oil can form a protective film on the metal surface by adding a variety of high-performance additives such as anti-wear agents, isolating direct contact between metal parts, thereby reducing friction and wear. At the same time, these additives can also improve the stability and service life of hydraulic oil and protect the integrity and performance of the system. Therefore, when selecting and using anti-wear hydraulic oil, its anti-wear performance and other comprehensive properties should be fully considered to ensure the normal operation and long-term stability of the hydraulic system.
