In the daily operation of many excavator users, oil is often added directly to the diesel engine to save costs. The reason why the excavator repair oil cannot be mixed with the risk factors will be described in detail below.
First, the mixture of new and old oils will reduce the performance of the old and new oils and cannot be mixed. There are many oxidizing substances in old oil. When the new oil is mixed with the old oil, the oxidation and deterioration rate of the new oil will increase, thus reducing the use effect and time of the new oil.
Secondly, when the oil is turbid, the oil grades of different brands cannot be mixed. Due to different brands and different numbers of chemical additives in the oil, these additives sometimes react chemically to reduce lubrication, and acid generating compounds aggravate the corrosion of engine components. Most dispersed oils now use sulfonate detergents, detergents and some oil dispersed salicylates. Sulfonates, salicylates and the use of other lubricants are incompatible, if the two lubricant mixtures will be layered, turbidity, deterioration of cleaning ability, etc.
Through the above two reasons, we can analyze the reasons why the excavator maintenance oil cannot be mixed. I believe you have understood the reasons why the excavator maintenance oil cannot be mixed. In addition to the problems caused by mixed use of excavator maintenance oil, the Mini Edition also reminds every excavator maintenance machine user to select the specified type of oil according to the requirements of the manual in daily use.
There are five main hazards after the excavator repairs the oil mixture: one is abnormal smoke in the exhaust pipe, such as black smoke or blue smoke. After the oil is mixed, the oil is likely to become thin, so it can be easily carried to the cylinder for combustion. This causes the engine to smoke. After mixing the engine oil, it may also make the cylinder seal loose and easy to make the engine smoke.
Accelerating the formation of oil sludge will reduce the heat dissipation effect of lubricating oil, make the engine easy to form high temperature, resulting in engine failure. Some oil sludge exists in the form of particles and solids, which accelerates the wear of the engine. Some mud will block the filter and oil path, which will easily lead to poor recovery of lubricating oil, and the engine will not be lubricated, with very serious consequences.
Discoloration of the mixed oil may cause the rod or piston seal to change, which may easily cause damage or discoloration of the piston rod or piston ring. If it is used for a long time, the piston rod or piston ring will be seriously worn and the service life of the engine will be affected.
After the piston ring is broken and mixed, the viscosity of the oil will change, not only smaller but also larger. When the viscosity of lubricating oil increases, the lubricating effect will decrease correspondingly, which may lead to the fracture of piston ring.
