来源:https://www.smxnykj.com/ 发布时间:日期:2022-07-13
1.润滑油的组成
1. Composition of lubricating oil
润滑油是由基础油、添加剂、染色剂三部分组成,基础油是润滑油的主要成分,决定者机油的基本性能,添加剂可弥补和改善基础油性能方面的不足,赋予某些新的性能。
Lubricating oil is composed of base oil, additives and colorants. Base oil is the main component of lubricating oil, which determines the basic performance of engine oil. Additives can make up for and improve the performance of base oil and give some new performance.
2、润滑油的作用
2. Function of lubricating oil
机油即发动机润滑油,发动机是汽车的心脏,发动机有许多相互摩擦运动的金属部件,这些部件运动速度快、环境差、工作温度可达400至600度,在这样恶劣的工况下,只有合格的润滑油才可降低发动机零件的磨损,延长其使用寿命。
Engine oil is the engine lubricating oil. The engine is the heart of the car. The engine has many metal parts that rub against each other. These parts move fast, the environment is poor, and the working temperature can reach 400 to 600 degrees. Under such bad conditions, only qualified lubricating oil can reduce the wear of engine parts and prolong their service life.
3、基础油的分类
3. Classification of base oil
1、矿物基础油
1. Mineral base oil
通过一系列物理、化学方法从原油当中加工并提取出来的。
Processed and extracted from crude oil through a series of physical and chemical methods.
2、合成技术基础油
2. Synthetic technology base oil
由矿物基础油和合成基础油通过精心的调配得到,它的性能高于矿物基础油但低于全合成基础油。
It is obtained by carefully mixing mineral base oil and synthetic base oil. Its performance is higher than that of mineral base oil but lower than that of fully synthetic base oil.
3、全合成基础油
3. Fully synthetic base oil
是通过复杂的物理和化学工艺,诸如分子结构重整及合成得到,生产成本更为昂贵,性能更为优越。
It is obtained through complex physical and chemical processes, such as molecular structure reforming and synthesis. The production cost is more expensive and the performance is more superior.
