空压机润滑油为什么会变黑？

1、氧化：

1. Oxidation:

空压机润滑油在高温和金属催化下与空气以及氮氧化物和硫化物产生氧化反应，生成醇、醛、酮、酸及含氧不溶物。

Under high temperature and metal catalysis, air compressor lubricating oil reacts with air, nitrogen oxides and sulfides to produce alcohols, aldehydes, ketones, acids and oxygen-containing insoluble substances.

2、分解：

2. Decomposition:

高温下长链的烃类分解成小分子烃化物及气体。

Long chain hydrocarbons decompose into small molecules and gases at high temperature.

3、乳化：

3. Emulsification:

由于被吸入的空气含有水分，从而使本来不能混合在一起的“油”和“水”两种液体混合在一起，长时间使用又未更换油的情况下，其中一种液体离散为许多微粒分散于另一种液体中，成为乳状物，被乳化的空气压缩机油品的润滑效果降低。

Because the inhaled air contains water, the "oil" and "water" which can not be mixed together are mixed together. When the oil is used for a long time without changing the oil, one of the liquid is dispersed into many particles and dispersed in the other liquid, which becomes emulsion. The lubricating effect of the emulsified air compressor oil is reduced.

空气压缩机润滑油高温产生故障：

High temperature fault of air compressor lubricating oil:

1.机械内部铁屑

1. Scrap iron inside the machine

2.吸入空气有微粒

2. There are particles in inhaled air

3.周围环境污染(化学药品等)

3. Environmental pollution (chemicals, etc.)

空压机润滑油变黑的原因：

Causes of blackening of air compressor lubricating oil:

1.添加剂遇热

1. The additive is heated

2.清洗出原本或工作时产生的积炭

2. Clean out the original or working carbon deposit

3.分散剂过多

3. Too much dispersant

4.积碳

4. Carbon deposition

5.变质

5. Deterioration

6.混入杂质

6. Mixed impurities

7.机器磨损过度，金属屑进入

7. The machine is worn excessively and the metal chips enter

以上的种种原因，都是产生空压机润滑油变黑的原因，我们要随时提高警惕，并严格做到：

The above reasons are all the reasons for the blackening of air compressor lubricating oil. We should be vigilant at any time and strictly:

1.确保添加的空压机油与正在使用的空压机油一致，严防两种油品混用，致使机油结焦卡死主机。

1. Ensure that the added air compressor oil is consistent with the air compressor oil in use, and strictly prevent the mixing of the two kinds of oil products, causing the engine oil coking and blocking.

2.不定期检查空压机内油品的使用情况，定期做好保养更换工作。

2. Check the use of oil in the air compressor irregularly, and do a good job of maintenance and replacement regularly.

3.经常性的清理空气滤芯的灰尘颗粒，视工况做好保养更换工作，使空气滤芯能有效过滤掉空气中的粉尘杂质。

3. Regularly clean the dust particles of the air filter element, and do a good job of maintenance and replacement according to the working conditions, so that the air filter element can effectively filter out the dust impurities in the air.

4.有周期的做好风冷冷却器的清洁工作，确保冷却器的冷却效果。

4. Clean the air-cooled cooler periodically to ensure the cooling effect of the cooler.
