If the fuel filter, oil filter, air filter, hydraulic oil filter and various filters are too dirty, the filtering effect will be worse; how to use and maintain it properly can not only improve the filter The efficiency of the cleaner can also greatly extend the service life of the equipment.
First, the role of oil filter: filter impurities
Under normal circumstances, the various components in the engine are normally operated by the lubrication of the engine oil, but metal debris, dust entering, oxidized carbon deposits and some water vapor generated by the components during operation will continuously mix in In oil, a longer time will reduce the normal service life of the oil, and in severe cases may affect the normal operation of the engine.
Therefore, the role of the oil filter becomes apparent at this time. Simply put, the role of the oil filter is to filter most of the impurities in the oil, keep the standby oil clean, and extend its normal service life. In addition, the oil filter should also have strong filtering ability, low circulation resistance, and long life.
Composition of oil filter: housing filter
Simply put, the oil filter is mainly composed of filter paper and housing. Of course, there are auxiliary components such as seals, support springs, and bypass valves. These auxiliary components are not small. For example, the role of the bypass valve is that when the filter paper fails due to excessive impurities, the oil will pass through the bypass The valve flows into the engine for lubrication.
However, from the appearance we can only see the oil filter as a whole, filter paper, bypass valve and other parts can not be seen.
Third, the oil filter maintenance cycle: a vulnerable component
Under normal circumstances, the filter is included in the wearing parts. If it is not replaced for a long time, it may cause the loss of the function of the oil filter and eventually affect the engine operation.
Fourth, the method of distinguishing the advantages and disadvantages of oil filters:
1. Appearance: fine and rough appearance
Fake oil filters are rough on the surface of the casing, and the font is usually illegible. The factory logo font on the surface of the real oil filter is very clear, and the surface paint texture is very good. Careful friends can easily see the difference through comparison.
2, filter paper: the filtering ability
The fake oil filter has a relatively poor ability to filter impurities, which is mainly reflected in the filter paper. Too dense filter paper will affect the normal oil flow; and too loose filter paper will cause a large amount of unfiltered impurities to continue to flow randomly. Causes dry friction or excessive wear on engine internal parts.
3. Bypass valve: points of auxiliary function
The bypass valve is a device for emergency conveyer oil when the filter paper is blocked due to excessive impurities. However, the built-in bypass valve of most fake oil filters is not obvious, so when the filter paper fails, the oil cannot be delivered in time, which will cause some parts in the engine to dry friction.
4. Gaskets: points of sealing and oil leakage
Although the gasket looks a little inconspicuous, the seal between the parts depends on it. The material of the gasket in the fake oil filter is relatively poor, and it is likely to cause its sealing to fail under high temperature and high intensity work of the engine, and eventually lead to oil leakage.
There are many types of construction machinery parts. It is not easy to master the maintenance of the parts. During the construction process of the construction machinery, pay more attention to the operation of the equipment. If there are abnormal conditions, please stop the machine for inspection.
