The operation of loader is inseparable from many factors, among which hydraulic oil is one of them. Someone has fed back such a problem that the hydraulic oil of the loader turns black. Does this mean that the hydraulic oil is unqualified? In fact, the blackening of hydraulic oil really has a lot to do with its quality. It is rare to choose high-quality oil produced by regular manufacturers. The reasons for the blackening of the hydraulic oil of general loaders still need to be analyzed from the conditions in use:

一、高温影响

1、 High temperature effect

抗磨液压油长期处于一个高温环境中，会出现氧化失效，变黑、变稠的现象；油泥、积炭、漆膜等物质不断增加抗磨液压油的氧化，导致其油品变质，从而导致氧化出现变黑。

The anti-wear hydraulic oil is in a high temperature environment for a long time, which will lead to oxidation failure, blackening and thickening; Oil sludge, carbon deposit, paint film and other substances continuously increase the oxidation of anti-wear hydraulic oil, leading to deterioration of its oil products, resulting in oxidation blackening.

二、杂质

2、 Impurities

主要来源于空气中的水、尘埃、金属磨屑、粉尘等杂质进入油品、抗磨液压油受到污染。

It mainly comes from the contamination of water, dust, metal wear debris, dust and other impurities in the air into oil products and anti-wear hydraulic oil.

三、换油不干净

3、 Oil change is not clean

装载机在换油的时候是否将油箱中的液压油全部清空，并用新油循环系统之后，将油箱全部用棉布擦拭干净之后再加入新油。如果没等把油箱擦拭干净，就可能会存有大量的铁屑残留在油箱中，导致新油被重新污染而发黑。新机器，在设备磨合时，会产生大量铁屑残留在油箱中，也会导致新油被污染而发黑。

Whether the loader empties all the hydraulic oil in the oil tank when changing the oil, and after using the new oil circulation system, wipe all the oil tanks with cotton cloth before adding new oil. If the oil tank is not wiped clean, there may be a large amount of iron filings left in the oil tank, causing the new oil to be re polluted and blackened. When the new machine is running in, a large amount of iron filings will be left in the oil tank, which will also cause the new oil to be polluted and blackened.

四、液压系统设计不合理

4、 Unreasonable design of hydraulic system

装载机液压油变黑之后，如果替换了新的液压油使用一段时间又变黑了，除了排查元件是否有问题外，小编建议确认液压系统设计是否合理，如果设计不合理应该及时通过相应的技术进行补救。

After the hydraulic oil of the loader turns black, if it turns black again after being used for a period of time after being replaced with a new hydraulic oil, in addition to checking whether there is a problem with the components, the small editor suggested to confirm whether the design of the hydraulic system is reasonable. If the design is unreasonable, it should be remedied by the corresponding technology in a timely manner.

如果液压油变黑或有异味，这个时候就不能继续使用了，否则会导致压力上不去，而且液压系统使用变质的液压油，很可能会导致泵、阀、油缸等元件被损坏，得不偿失。

If the hydraulic oil turns black or has peculiar smell, it can't be used any more at this time, otherwise the pressure will not go up. Moreover, the use of deteriorated hydraulic oil in the hydraulic system may cause damage to the pump, valve, cylinder and other components, which is not worth the loss.

当装载机液压油油品变黑时，找出导致油品变黑的原因，建议直接更换油品，液压油的使用维护都非常重要，在使用液压油的时候，一定要按照油品厂家的建议来使用油品，而不是一味地追求低价。

When the hydraulic oil of the loader turns black, find out the cause of the oil turning black. It is recommended to replace the oil directly. The use and maintenance of the hydraulic oil are very important. When using the hydraulic oil, you must use the oil according to the recommendations of the oil manufacturer, rather than blindly pursuing low prices.
