Why does the excavator engine change the oil frequently?
1, the oil and other goods are the same as the corresponding warranty period, when the use of time to a certain limit, the performance will change, the oil once the deterioration will cause a lower lubrication, resulting in mechanical parts wear.
2, when the motive is running for a long time, the internal oil will produce a lot of impurities. As time goes on, the running time is long, the impurities in the oil will increase, and the wear speed of the mechanical parts will be accelerated.
3, oil running at high temperature will cause chemical reaction, which will affect the performance of the machine itself.
What are the effects of not changing the oil?
1, resulting in the reduction of oil pressure
A. oil storage is too small, resulting in the phenomenon of engine oil or less oil.
B. oil has a lot of impurities, serious deterioration occurs, resulting in the increase of oil viscosity, thereby affecting the oil intake and pumping.
C. does not change the oil on time, it also brings the problem of high oil pressure. And too high oil pressure will cause premature damage to the gasoline filter, causing carbon deposition in the engine cylinder. It will also reduce the life of the engine.
2, lead to oil pressure rise
A. when the season changes, the corresponding performance oil is not replaced, resulting in the oil can not adapt to the temperature environment and produce a lot of viscosity.
B. oil deterioration results in gel formation, resulting in reduced oil fluidity.
3, filter cartridge or oil channel blockage
When the high pressure of uncombustible gas, acid, water, sulfur and nitrogen in the room enters the oil of the crankcase with the gap between the piston ring and the cylinder wall, it is mixed with the metal powder produced by the wear and tear of the parts and forms the mud every day.
4. Sediment deposition
When the oil is not replaced for a long time, the oil will produce a large amount of mud in a long time, which will seriously affect the engine's lubricating degree and even cause the filter and oil holes to clog, so that the wear degree of each component of the engine is increased.
5. High water temperature
A. when the temperature of the mechanical water is too high, it will directly affect the deformation and even damage between the cylinder head and the cylinder body. Once such a fault occurs, it will directly affect the normal use of the whole machine.
B. in the daily replacement of oil at the same time, the oil filter element must be replaced at the same time, do not just replace the oil and ignore the existence of the oil filter element. Because the old machine filter will directly affect the quality of the new oil, if only the oil is replaced and the oil filter core is ignored, the effect of the new oil can not be achieved.
C. oil category replacement should change with the season. For example, the oil in the winter must be thinner in summer and more viscous in summer. If the oil is mixed, it will not help the formation of oil film of the oil itself, which will aggravate the wear of its parts.
