油品分类
Classification of oil products
矿物油（一次加氢、脱蜡、蒸馏等工艺称为I类基础油；二次工艺称为II类；的是三次工艺称为III类，国内称为半合成油，国外还是归类成矿物油。真正的半合成油应是III类基础油添加20%以上的合成酯，才能称为我们所说半合成油。
Mineral oil (primary hydrogenation, dewaxing, distillation and other processes known as class I base oil; secondary process known as class II; the best is the third process known as class III, known as semi-synthetic oil at home, or classification of mineral oil abroad. Real semi-synthetic oil should be class III base oil added more than 20% synthetic ester, can be called what we call semi-synthetic oil.
合成油（聚α-烯烃类简称PAO，酯类合成油简称POE，醚类合成油简称PAG等）
Synthetic oils (polyalpha alkenes referred to as PAO, ester synthetic oils referred to as POE, ethers, synthetic oils referred to as PAG, etc.)
润滑油产品的组成：基础油及添加剂（抗氧化剂、抗乳化剂、防锈剂、消泡剂、黏度改进剂、分散剂、抗高温酯等）调和而成产品。
Composition of lubricating oil products: base oil and additives (antioxidants, anti-emulsifiers, rust inhibitors, defoamers, viscosity improvers, dispersants, high-temperature esters, etc.) blended products.
空压机油在空压机中的作用
The function of air compressor oil in air compressor
冷却：空压机在工作的时候会产生大量的热量，油品就起到了散热的作用。
Cooling: air compressor will generate a lot of heat when working, and oil will play a role of heat dissipation.
润滑：油品在金属表面等于形成了一层保护膜减少磨损，46号比32号油的油膜更厚，特别是冷启动时更能保护金属表面。
Lubrication: Oil on the metal surface is equivalent to the formation of a protective film to reduce wear and tear, 46 than 32 oil film thicker, especially when cold start metal surface protection.
密封：螺杆主机压缩腔内润滑油可以减少泄漏。
Sealing: screw main compression chamber lubricants can reduce leakage.
降声：降低主机运行时的噪音。
Drop noise: reduce the noise of the host when running.
空压机油使用周期
Service life of air compressor oil
空压机油的使用寿命大多是由其本身基础油类别决定的。
The service life of air compressor oil is mostly determined by its own base oil category.
空压机油生产厂商设定的使用周期一般为空压机标准工况（洁净的空气、运行温度在95度以内、空压机正常运行等），恶劣的工况会缩短油品的寿命。
Air compressor oil manufacturer set the use cycle is generally air compressor standard operating conditions (clean air, operating temperature within 95 degrees, normal operation of air compressor, etc.), poor working conditions will shorten the life of oil products.
在售后市场必须了解空压机的用油历史，如果以前的油品出现过问题或使用的不是正规的油品，请一定进行妥善处理。因为劣质的油品氧化物会残留在机器内，严重的影响新油的使用寿命。
In the after-sales market must understand the history of air compressor oil, if the previous oil problems or use is not a regular brand of oil, please be sure to properly handle. Because poor quality oil oxides will remain in the machine, seriously affecting the life of new oil.
I believe that after reading the introduction of this article, the Jinan air compressor http://www.jnkbjx.com will also have their own understanding of the future for such problems can be well solved.
