What is the difference between anti-wear hydraulic oil and engine oil

Anti wear hydraulic oil and engine oil have significant differences in function and scope of use. This article will explain the differences between anti-wear hydraulic oil and engine oil, and analyze their similarities and differences from different perspectives.

1. Definition and Function

Anti wear hydraulic oil is a special liquid working medium widely used in industrial and mechanical systems. It is mainly used for transmitting energy and controlling pressure. The anti-wear hydraulic oil requires good anti-corrosion, anti-oxidation, anti foam, rust prevention, anti-wear and other properties. It needs to withstand high pressure and high temperature, while also preventing oxidation and pollution to extend the service life of mechanical equipment.

Engine oil is a type of grease used to lubricate engine components. Its main platform and medium are internal combustion engines and diesel engines. The main function of engine oil is to reduce wear and friction, reduce heat loss of engine components, cool engine components, remove impurities inside the engine, and prevent corrosion inside the engine. The quality of engine oil determines the performance and lifespan of the engine.

2. Composition and properties

The base oil of anti-wear hydraulic oil is mineral oil, synthetic oil, etc., often supplemented with various additives such as friction agents, antioxidants, viscosity index improvers, etc. It needs to have stability under high temperature and high pressure, as well as excellent wear resistance, and can be used in high-pressure, high-speed, and low-temperature environments.

The base oil of engine oil is mineral oil and synthetic oil, with various additives added such as cleaning agents, viscosity index improvers, antioxidants, defoamers, etc. Engine oil needs to have excellent lubrication performance and reduce friction coefficient, while also preventing corrosion and wear inside the engine, maintaining stable viscosity and cleanliness.

3. Scope of use

Wear resistant hydraulic oil is used in hydraulic systems, precision machinery equipment, casting equipment, and equipment that requires prevention of coolant evaporation, lubrication system contamination, and corrosion. It is also used in equipment for industries such as aviation, military, and transportation.

Engine oil is used in internal combustion engines and diesel engines, as well as some industrial equipment. The service life and replacement cycle of engine oil are usually related to the engine service life and vehicle mileage. Using high-quality engine oil can extend the lifespan of the engine and improve its performance.

4. Summary

Anti wear hydraulic oil and engine oil have significant differences in function, composition, and scope of use. Anti wear hydraulic oil is mainly used for transmission and control of hydraulic systems and mechanical equipment, with excellent properties such as rust prevention, wear resistance, and oxidation resistance. Engine oil is used to lubricate engine components, including reducing wear and friction, cleaning impurities inside the engine, and preventing engine wear. When using, it is necessary to select suitable anti-wear hydraulic oil and machine oil according to different needs and conditions, and replace and maintain them according to requirements to maintain the normal operation of the equipment and extend its service life.
