Antiwear additives in hydraulic fluids are typically zinc dialkyldithiophosphate (ZDDP) compounds. These additives form a protective film on metal surfaces, reducing friction and preventing wear.
Antiwear additives in hydraulic oils: types and effects
Hydraulic oil is a liquid medium widely used in industry and manufacturing. It transmits power in a closed system and drives the movement of various machinery and equipment. However, hydraulic oil is affected by friction and wear during use, which can lead to reduced performance or even damage to the equipment. To solve this problem, many anti-wear additives are added to hydraulic oil to extend the service life of the equipment. This article will introduce in detail the common anti-wear additives in hydraulic oil and their functions.
Topic 1: Introduction to hydraulic oil
Hydraulic oil is a liquid medium commonly used in hydraulic systems to transmit power, lubricate and cool. Hydraulic oil has properties such as high pressure carrying capacity, good lubrication properties, good oxidation resistance and low viscosity. Hydraulic oil can be divided into many types according to its use, such as industrial hydraulic oil, machine tool hydraulic oil, aviation hydraulic oil, etc.
Topic 2: Overview of Antiwear Additives
Anti-wear additive is a special additive added to hydraulic oil. Its main function is to reduce friction and wear and improve the efficiency and life of the hydraulic system. Antiwear additives are generally divided into three types: lubricants, extreme pressure agents, and solid lubricants. The main function of the lubricant is to form a lubricating film on the friction surface to reduce the friction coefficient; the extreme pressure agent forms a chemical reaction under high pressure and high temperature to generate solid substances, reducing the direct contact of the friction surface; the solid lubricant is By forming a solid lubricating film on the friction surface, friction and wear are reduced.
Topic 3: The role of anti-wear additives in hydraulic oil
Adding anti-wear additives to hydraulic oil can significantly improve the efficiency and life of your hydraulic system. Its main functions are as follows:
Reduce friction and wear: Anti-wear additives can form a lubricating film on the friction surface, reducing the friction coefficient and reducing wear between hydraulic components.
Improve hydraulic efficiency: Anti-wear additives can increase the efficiency of hydraulic systems by reducing frictional resistance between hydraulic components.
Extended equipment life: By reducing friction and wear, anti-wear additives can significantly extend the life of hydraulic equipment.
Prevent hydraulic oil from oxidizing: Some anti-wear additives have antioxidant properties that can prevent hydraulic oil from oxidizing and deteriorating during use.
Anti-wear additives in hydraulic oil play an important role in improving the efficiency and life of hydraulic systems. This article introduces the basic knowledge of hydraulic oil, the types of anti-wear additives and their role in hydraulic oil. I hope that through the introduction of this article, readers can have a deeper understanding of the role of anti-wear additives in hydraulic oil.
