Filter is an important part of engineering machinery, oil filters, fuel filters, air filters, hydraulic filters, filters for the construction machinery you are aware of them and take care of your specific role it?


Xiao Bian collected daily use of construction machinery filter should pay attention to the issue, and some maintenance knowledge!


Role of the oil filter is to filter engine sludge, engine oil degradation arising from impurity itself, prevent the deterioration of the oil, to minimize wear of the components during operation of.


Under normal circumstances, the engine oil filter change intervals for the first 50 hours of the replacement, then every 250 hours of work to be replaced.


Oil, fuel filter FAQs


1. In what special circumstances, need to replace the oil filter, fuel filter?


Fuel filter is to iron oxide fuel, removal of dust and other magazines, to prevent clogging of the fuel system, reduce mechanical wear and ensure stable operation of the engine.


Under normal circumstances, the engine fuel filter replacement cycle for the first 250 hours of work to replace, then be replaced every 500 hours of work, flexibility should replace specific time depending on the fuel quality levels.


When the filter pressure gauge indicates the pressure alarm or not normal, you need to check whether there are anomalies filter, if any, must be changed.


When there is a leak or rupture of the filter surface deformations, you need to check whether there are anomalies filter, if any, must be replaced.


2. Are the oil filter filtration accuracy as high as possible?


For an engine or equipment, a proper filter filtering accuracy should achieve a balance between filtration efficiency and dust capacity.


Use high filtration precision filter, it may be because of low dust capacity cartridges and lead to shortened life of the filter, thereby increasing the risk of premature clogged oil filter.


3. The low-grade oil, fuel filters and pure oil, fuel filters and equipment to effect what is the difference?


Pure oil, fuel filter can effectively protect the equipment, prolonging the life of another, inferior oil, fuel filter can not be good protective equipment, can not extend the life of equipment, or even worsen the situation using the equipment.


4. Use high quality oil, fuel filter to give the machine What are the benefits?


Use high-quality oil, fuel filter can effectively extend the life of equipment, reduce maintenance costs, save money for users.


5. equipment warranty period, and the use of long-life, is not no need to use excellent quality filter?


To equip the engine easier to wear, resulting in pull-cylinder. So the old filter need quality equipment to stabilize the escalating wear sustain engine performance.


Otherwise, you will have spent large sums of money to carry out repairs, or if you have been forced to throw away your engine scrapped. By using pure filter, you can ensure that the total spent on operating costs (maintenance, repair, overhaul, and the depreciation of the total cost) minimum, but also extend the life of the engine.


6. As long as cheap filter, installed in the engine can be well above the line yet?


Many domestic manufacturers of filter will simply copy the original pieces mimic the geometry and appearance, while the filter should be achieved by engineering standards downplayed, or simply do not know what is engineering standards.


Filter designed to protect the engine system, if the filter performance can not meet the technical requirements of the filtering effect lost, then the performance of the engine will be significantly reduced, and to shorten the life of the engine.


For example, the life of diesel engines and engine damage will advance directly to the "eat" into the 110-230 grams of dust related. Therefore, the filter will make more inefficient inferior magazine into the engine system, resulting in engine overhaul in advance.


7. Use the filter does not cause any problems in the machine, so the user is not no need to buy more over the money to buy high-quality?


Inefficiencies caused by the poor quality of the filter to affect the engine, you may or will not see immediately. Engine seems to run fine, but harmful impurities may have already entered the engine system and starts causing corrosion of engine parts, rust, wear and so on.


These damages are hidden, when accumulated to a certain extent will explode. While it can not see the signs, but that does not mean the problem does not exist. Once there is a problem, it may be too late, so stick with quality guaranteed pure filter allows the engine to get maximum protection.


Air filter is located in the engine intake system, whose main role is to filter the air entering the cylinder to be harmful impurities, in order to reduce premature wear of the cylinder, pistons, piston rings, valves and valve seats, and thus for the normal operation of the engine, the output powered by guarantee.


Under normal circumstances, the air filter is used to replace the different models at different times, but when the air filter clogged indicator lights, outside air filter must be cleaned. If poor working conditions, should shorten the air inside and outside the filter replacement cycle.
