如果在运行挖掘机时出现类似于排气管冒黑烟或者蓝烟、油泥现象严重、活塞环出现断裂、活塞与缸筒磨损严重等问题，那可能就是机油混用产生的后果了，下面来简单分析一番。
If there is similar to black smoke or blue smoke from the exhaust pipe, serious oil mud phenomenon, piston ring fracture, piston and cylinder wear and other problems in the operation of the excavator, it may be the consequence of oil mixing, here is a simple analysis.
挖掘机机油为什么不能混用？新旧机油不能混用，在旧机油内含有大量的氧化性物质，当新机油和旧机油混合后，新机油的氧化变质速度会增加，从而减少新机油的使用效果和使用时间。不同、不同标号的机油不能混用；由于不同、不同标号机油里的化学添加剂不同，这些化学添加剂有时会起反应，降低润滑效果，产生酸碱化合物加剧发动机零件的腐蚀。
Why can't excavator oil be mixed? Old and new oil can not be mixed, in the old oil contains a lot of oxidizing substances, when the new oil and the old oil mixed, the oxidation deterioration rate of the new oil will increase, so as to reduce the use effect and use time of the new oil. Different brands, different grades of oil can not be mixed; Due to different brands, different grades of oil in the chemical additives are different, these chemical additives sometimes react, reduce the lubrication effect, produce acid and alkali compounds aggravate the corrosion of engine parts.
华体会国际 租赁人员提醒大家，同类产品除了尽量避免新旧油混用之外，原则上可以混用，因为他们结构差不多，如果质量有高低，混用后就相当于低质量油，这样其实会造成浪费。如果因为需要调整油品黏度而采用其他油品混合，所选择油品必须是同产品，涉及到具体油品的话会比较，需要对它有相当的了解。
The leasing personnel of the extended arm excavator remind you that in addition to avoiding the mixing of new and old oil, similar products can be mixed in principle, because they have similar structure. If the quality is high and low, the mixture is equivalent to low quality oil, which will actually cause waste. If you need to adjust the viscosity of oil and use other oil mixture, the selected oil must be the same brand products, when it comes to specific oil will be more professional, need to have a considerable understanding of it.
对于不同类的机油，如果知道两种将要对混的油品都是不含添加剂或其中一个是不含添加剂，再或者两种机油都加添加剂但相互不起反应的，此时一般也可以混用。一般情况下，矿物油之间也可以混用，而矿物油和半合成油之间可混用得比较多。需要注意的是全合成油和矿物油之间的混合要慎重，如果不太了解的话，尽量还是避免混用。
For different types of oil, if you know that two kinds of oil will be mixed without additives or one of them does not contain additives, or two kinds of oil with additives but do not react with each other, this time can generally be mixed. Under normal circumstances, mineral oil can also be mixed between, and mineral oil and semi-synthetic oil can be mixed more. It is important to be careful when mixing synthetic and mineral oils, and avoid mixing them if you are not familiar with them.
所以才说，挖掘机添机油的混用行为不可取！以上内容便是原因了，如果你没有十分把握的话，不要将油品进行混用，否则一旦挖掘机出现问题，就追悔莫及了。更多问题您可来网站

So it is said that the mixed use of excavator oil is not desirable! The above is the reason. If you are not very sure, do not mix the oil, otherwise once the excavator has problems, it will be too late to regret. For more information, please visit www.wondgo.com.
