Filter element is the most important component of construction machinery. The quality of filter element affects the performance of construction machinery, as well as some maintenance knowledge, the function of oil filter is to filter the sludge in the engine, the impurity produced by the deterioration of the engine oil itself, to prevent the deterioration of the engine oil, and to minimize the wear and tear of the components in the process of running. In general, the engine oil filter replacement cycle for the first 50 hours of work to replace, after every 250 hours of work to replace. Frequently asked questions about oil and fuel filters 1. In what special circumstances, the need to replace the oil filter, fuel filter? Fuel filter is the fuel in the iron oxide, dust and other magazines to remove, prevent the fuel system plugging, reduce mechanical wear, to ensure the stable operation of the engine.
In general, the replacement cycle of the engine fuel filter for the first 250 hours to replace, after every 500 hours to replace, should be based on the fuel quality class different flexible replacement time. When the filter pressure gauge alarm or indication of abnormal pressure, need to check whether the filter is abnormal phenomenon, if so, must be changed. When the filter surface has leakage or rupture deformation phenomenon, need to check whether the filter is abnormal phenomenon, if there is, must be replaced. 2. Whether the oil filter element of the filter method as high as possible precision? For an engine or equipment, an appropriate construction machinery filter accuracy should be in the filter efficiency and ash capacity between a balance. If the filter element with high filtering precision 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 the oil filter element being blocked prematurely. 3. What is the difference between inferior engine oil, fuel filter element and pure engine oil, fuel filter element on equipment? Pure engine oil and fuel filter element can effectively protect equipment, extend the service life of other equipment, inferior engine oil and fuel filter element can not protect equipment well, can not extend the service life of equipment, it can even worsen the use of equipment. Four. What are the benefits of using high-quality oil and fuel filters for the machine? The use of high-quality oil, fuel filter can effectively extend the life of equipment, reduce maintenance costs, save money for users. 5. Is it not necessary to use high-quality filter element when the equipment has been out of warranty and has been in use for a long time? The equipped engine is more prone to wear and tear, causing the cylinder to pull. So older equipment needs high-quality filters to stabilize escalating wear and maintain engine performance. Otherwise, you'll have to spend a lot of money on repairs, or you'll have to scrap your engine in advance.
By using a pure filter, you can ensure that you spend the total operating costs (maintenance, repair, overhaul and depreciation of the total cost) , but also to extend the life of the engine. 6. Construction machinery filter as long as cheap, can be installed on the engine on the line? Many manufacturers of filter elements of construction machinery in China simply copy the original parts' geometric size and appearance, but pay little attention to the engineering standards that the filter elements of construction machinery should meet, you Don't even know what engineering standards are. In order to protect the engine system, if the performance of the filter element can not meet the technical requirements and lose the filtering effect, then the performance of the engine will be significantly reduced, and shorten the service life of the engine. These damages are recessive and will erupt when they accumulate to a certain extent. Just because there are no symptoms doesn't mean there isn't a problem. Once a problem is detected, it may be too late, so adhere to the use of high-quality and guaranteed pure construction machinery filter can be the engine for maximum protection. The air filter element is located in the intake system of the engine. Its main function is to remove harmful impurities from the air that will enter the cylinder to reduce the early wear of the cylinder, piston, piston ring, valve and valve seat, so as to ensure the normal operation and output power of the engine.
