装载机液压油发黑从油品上分析，使用不合格的油品，非标油品，引起油品发黑。这种情况在注意选择到正规厂家生产的高品质油时很少会出现。一般的装载机液压油发黑的原因还是需要从使用中的情况来分析：

The loader hydraulic oil is blackened. According to the analysis of oil products, unqualified oil products and non-standard oil products are used, resulting in oil blackening. This situation rarely occurs when we pay attention to the selection of high-quality oil produced by regular manufacturers. The reason for the blackening of hydraulic oil of general loader still needs to be analyzed from the situation in use:

装载机液压油发黑的原因

Causes of blackening of loader hydraulic oil

一、高温影响。抗磨液压油长期处在高温环境中，会氧化失效，出现变黑、变稠的现象；积炭、油泥、漆膜等物质的增加；抗磨液压油氧化,油品变质，从而导致氧化变黑。

1、 High temperature effects. When the anti-wear hydraulic oil is in high temperature environment for a long time, it will oxidize and become black and thick; Increase of carbon deposit, oil sludge, paint film and other substances; Oxidation of anti-wear hydraulic oil and deterioration of oil, resulting in oxidation and blackening.

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

2、 Impurities. It mainly comes from the dust, water, metal wear debris, dust and other impurities in the air, which enter the oil and anti-wear hydraulic oil and are polluted.

三、换油不干净。装载机换油时是否将油箱中的液压油全部清空，并用新油循环循环系统后，将油箱全部用棉布擦拭干净后再加新油，如果没有，就可能有大量铁屑残留在油箱中，也会导致新油被污染而发黑。由于是新机器，在设备磨合时会产生大量的铁屑，不知你换油的时候是否将油箱中的液压油全部清空，并用新油循环循环系统后，将油箱全部用棉布擦拭干净后再加新油，如果没有，就可能有大量铁屑残留在油箱中，也会导致新油被污染而发黑。

3、 The oil change is not clean. Whether the hydraulic oil in the oil tank is completely emptied during the oil change of the loader, and after using the new oil circulation system, wipe all the oil tank with cotton cloth and add new oil. If not, a large amount of iron filings may remain in the oil tank, which will also cause the new oil to be polluted and blackened. As it is a new machine, a large amount of iron filings will be generated during the running in of the equipment. I wonder whether you empty all the hydraulic oil in the oil tank when changing the oil, and after using the new oil circulation system, wipe all the oil tank with cotton cloth and add new oil. If not, a large amount of iron filings may remain in the oil tank, which will also lead to the pollution and blackening of the new oil.

四、液压系统设计不合理。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之外，小编建议确认液压系统设计是否合理，如不合理及时通过相应的技术补救。

4、 The design of hydraulic system is unreasonable. After the hydraulic oil of the loader turns black, if the new hydraulic oil is replaced and turns black again after a period of use, in addition to checking whether there are problems with the components, the Xiaobian suggests to confirm whether the design of the hydraulic system is reasonable. If it is unreasonable, it should be remedied in time through corresponding technology.
