Filter element is an important part of construction machinery, oil filter element, fuel filter element, air filter element and hydraulic filter element. Do you know their specific functions and maintenance points?
Oil filter element is to filter the sludge in the engine, the impurities produced by the deterioration of engine oil itself, prevent the deterioration of engine oil, and minimize the wear and tear of components in the operation process.
Fuel filter element removes magazines such as iron oxide and dust from fuel, prevents blockage of fuel system, reduces mechanical wear and ensures stable operation of engine.
Below are the problems that should be paid attention to in the daily use of construction machinery filter elements, as well as some maintenance knowledge!
1. Under what special circumstances, oil filter element and fuel filter element need to be replaced?
Generally speaking, the replacement cycle of engine oil filter element is 50 hours for the first work, and then 250 hours for each work; the replacement cycle of fuel filter element is 250 hours for the first work, and then 500 hours for each work. Specifically, the replacement time should be flexibly grasped according to the different fuel quality grades.
When the filter pressure gauge alarms or indicates that the pressure is abnormal, it is necessary to check whether the filter has abnormal phenomena, and if so, it must be changed.
When there is leakage or rupture deformation on the surface of the filter element, it is necessary to check whether the filter has any abnormal phenomena, and if so, it must be replaced.
2. Is the higher the accuracy of oil filter element, the better?
For an engine or equipment, an appropriate filter accuracy should achieve a balance between filtration efficiency and ash capacity.
If the filter element with high filtration accuracy is used, the service life of the filter element may be shortened because of the low ash content of the filter element, thus increasing the risk of premature blockage of the oil filter element.
3. What’s the difference between inferior oil and fuel filter element and pure oil and fuel filter element on equipment? Pure oil and fuel filter element can effectively protect equipment and prolong the service life of equipment. inferior oil and fuel filter element can’t protect equipment well, can’t prolong the service life of equipment, and even worsen the service condition of equipment.
4. What benefits can fuel filter element bring to the machine with high quality oil?
The use of high-quality oil and fuel filter can effectively prolong the life of equipment, reduce maintenance costs and save money for users.
5. Is it unnecessary to use high-quality excellent filter element when the equipment has passed the warranty period and has been in use for a long time?
The engine of old equipment is easier to wear and tear, resulting in cylinder pulling. Therefore, the old equipment needs high quality filter to stabilize the gradual upgrading of wear and maintain engine performance.
Otherwise, you will have to spend a lot of money on maintenance, or you will have to scrap your engine in advance. By using pure filter elements, you can ensure that the total operating costs (maintenance, maintenance, overhaul and depreciation) you spend are the lowest, and you can extend the life of the engine.
6. The filter element used does not bring any problems to the machine, so it is not necessary for users to buy high-quality?
The impact of inefficient and inferior filter elements on the engine may or may not be seen immediately. The engine seems to be running normally, but harmful impurities may have already entered the engine system, and have begun to cause engine parts corrosion, rust, wear and tear.
These damages are recessive and will erupt when accumulated to a certain extent. Although there are no signs now, it does not mean that the problem does not exist. Once a problem is found, it may be too late, so sticking to the use of high-quality and guaranteed pure filter elements can maximize the protection of the engine.
