Machine oil is a kind of lubricating oil used to lubricate mechanical parts, also known as engine oil. It is made of a series of specific chemical substances, which can reduce friction and wear and extend the service life of mechanical parts.

mechanical oil is usually mixed with base oil and additives. The base oil is a product of refining petroleum and may be a mineral oil, a synthetic oil or a bio-oil. Additives are specific chemical substances used to increase the performance and additional functions of mechanical oil. For example, additives can increase the high temperature resistance of mechanical oil, protect components from oxidation and corrosion, clean the engine, reduce the formation of engine deposits, etc. The role of

mechanical oil in mechanical equipment is mainly to reduce the friction between components and prevent wear and corrosion of components. In the moving parts, the machine oil is compressed and squeezed out, forming a lubricating film, reducing the friction and wear of the metal. If the moving parts are not lubricated with mechanical oil, it will cause premature wear and failure of the machine, and even cause failure.

In addition to lubrication, mechanical oil can also reduce the temperature of mechanical equipment by taking part of the heat. For example, in an engine, mechanical oil not only acts as a lubricant, but also reduces the temperature of the engine by carrying part of the heat to keep the engine running stable.

machine oil is divided into many types, including special machine oil and general machine oil for different machines and equipment. General mechanical oil is suitable for a variety of machines and equipment, such as lubricating air compressors, engines, bearings, pumps and gears. The special mechanical oil is designed to meet a specific friction pair or working conditions, such as industrial hydraulic oil, locomotive lubricating oil, aircraft lubricating oil, etc. When

choose mechanical oil, it is necessary to consider the environment and use requirements of the machine and equipment to determine the appropriate mechanical oil grade and type. The use of improper machine oil may cause problems such as degradation of machine performance and damage to parts.

In general, mechanical oil plays a very important role in mechanical equipment, which can extend the service life of mechanical parts and improve the performance and efficiency of the machine. Therefore, the selection of suitable mechanical oil and regular replacement and maintenance is the key to maintain the healthy and stable operation of mechanical equipment.
