First, what are the serious consequences of Ten field excavator not changing oil on time?
1, not timely replacement of oil will also lead to high oil pressure. Too high oil pressure can cause the fuel filter to fail prematurely and lead to carbon buildup in the engine cylinders. It also shortens the life of the engine.
Failure to replace the oil in the cylinder can lead to the following problems resulting in increased oil pressure:
Oil viscosity is too high (such as summer oil can not replace winter oil); Oil deterioration and gelation lead to lower oil fluidity; The filter or oil line is blocked.
2. Failure to replace the oil in time will lead to low oil pressure failure. The most immediate consequence of low oil pressure is that it can lead to semi-dry or dry friction between various components. The engine has obvious abnormal noise, which can cause combustion in severe cases.
Failure to change the oil in time can lead to the following problems resulting in a drop in oil pressure: the oil storage is too small, resulting in no lubrication or reduced oil volume in the lubrication system; Dirty or sticky oil allows the pump to effectively suck in and pump oil. If the oil is thin or the engine temperature is high and the engine oil is thin, it will leak from the friction gap of the engine.
3, not timely replacement of oil will also cause too much sludge. Sludge is usually formed by high pressure unburned gases in the combustion chamber, acid, moisture, sulfur and nitrogen oxides entering the crankcase oil through the gap between the piston ring and the cylinder wall, which is then mixed with the resulting metal powder. Parts wear out. Together, it slowly builds up and forms sludge.
There's too much sludge. Failure to change the oil in time can lead to an increase in sludge, resulting in clogging of filters and oil holes, making engine lubrication difficult and increasing engine wear.
4, not timely oil change. The most serious consequence is the wear and tear of various mechanical components of the engine, such as pistons and cylinders. Once the piston and cylinder problems, the machine needs to be overhauled, and every owner does not want to see an overhaul.
5, serious cylinder wear
Lack of oil, oil and too much sludge in oil can cause severe wear on cylinders and pistons. If the oil is not changed in time, these problems will basically occur, so it is very necessary to change the oil on time.
Small hydraulic excavator engine needs to change the oil, this is very necessary, we should remember.
Second, the necessity of replacing the oil of the small excavator
1. Many people only know that the engine of a small excavator will often cause problems, but they do not know that the oil needs to be replaced in time. This oil has a shelf life. When time is long, performance degrades, leading to accelerated wear of mechanically worn parts.
2, when the engine oil runs at high temperature in the engine, its physical and chemical properties will change, and the mechanical properties will also change.
3, the engine runs for a long time, the impurities in the oil increase, which increases the wear rate of the mechanical parts.
