Filter commonly used maintenance knowledge
The filter element is the most important part of the construction machinery. The quality of the filter element affects the performance of the construction machinery. We have collected the problems that should be noticed in the daily use of the construction machinery filter element, as well as some maintenance knowledge!
Filter element is an important part of the construction machinery, oil filter, fuel filter, air filter, hydraulic filter, for these engineering machinery filter you understand their specific role and maintenance points?
The function of the oil filter is to filter the sludge in the engine. The engine oil itself degrades the generated impurities, prevents the oil from deteriorating, and minimizes the wear of various components during operation.
Under normal circumstances, the engine oil filter replacement cycle is changed for the first 50 hours, and then every 250 hours for replacement.
1. Under what special circumstances, need to replace the oil filter, fuel filter?
The fuel filter removes iron oxide, dust and other magazines from the fuel to prevent clogging of the fuel system, reduce mechanical wear and ensure the stable operation of the engine.
Under normal circumstances, the engine fuel filter replacement cycle for the first time 250 hours to replace the replacement, then every 500 hours for replacement, the specific should be based on the quality of the fuel level to grasp the replacement time.
When the filter pressure gauge alarms or indicates that the pressure is abnormal, it is necessary to check the filter for any abnormalities. If so, it must be changed.
When the surface of the filter element is leaking or cracked, it is necessary to check the filter for any abnormalities. If so, it must be replaced.
2. Is the filter method of the oil filter better?
For an engine or equipment, an appropriate filter element filtering accuracy should achieve a balance between filtration efficiency and ash content.
The use of filters with too high a filtration accuracy may result in a shortened service life of the filter elements due to the low capacity of the filter elements, thereby increasing the risk of premature plugging of the oil filter elements.
3. What is the difference between the role of inferior oil, fuel filter and pure oil, fuel filter on equipment?
Pure oil and fuel filter can effectively protect the equipment, extend the service life of the assembly, poor quality oil, fuel filter can not be a good protection equipment, can not extend the service life of the equipment, or even worsen the use of the equipment.
4. Using high-quality engine oil, fuel filter can bring any benefits to the machine?
The use of high-quality oil and fuel filter elements can effectively extend the life of equipment, reduce maintenance costs, and save money for users.
5. Is it necessary to use high-quality and excellent filter cartridges after the warranty period is long and the service life is long?
The equipped engine is more likely to wear and cause cylinder pull. Therefore, the old equipment needs high-quality filter elements to stabilize gradual wear and tear and maintain engine performance.
Otherwise, you will have to spend a lot of money on repairs, or you may have to throw away your engine in advance. By using a genuine filter cartridge, you can ensure the lowest total operating costs (total costs for maintenance, repairs, overhaul, and depreciation) and extend the life of the engine.
6. As long as the filter cartridge is cheap, can it be mounted on the engine safely?
Many filter manufacturers in China will simply copy the geometric dimensions and appearance of the original parts, but they will not pay attention to the engineering standards that should be achieved by the filter elements, and they may not even know what the contents of the engineering standards are.
When the filter element is designed to protect the engine system, if the performance of the filter element does not meet the technical requirements and the filter effect is lost, the performance of the engine will be significantly reduced and the service life of the engine will be shortened.
For example, the life of a diesel engine is directly related to 110-230 grams of dust that is “eaten” in advance of engine damage. Therefore, inefficient filter cartridges will cause more magazines to enter the engine system, leading to an overhaul of the engine.
7. The filter used does not bring any problems to the machine, so is it unnecessary for the user to buy more money to buy quality?
The impact of an inefficient filter on the engine may not be immediately visible to you. The engine seems to be operating normally, but harmful impurities may have already entered the engine system and begin to cause corrosion, rust, and wear of the engine parts.
These damages are recessive and will erupt at a certain degree of accumulation. Although you can't see the symptoms now, it does not mean that the problem does not exist. If problems are found, it may be too late, so insist on the use of high-quality, certified, genuine filter cartridges to maximize engine protection.
The air filter is located in the engine's air intake system. Its main function is to filter out the harmful impurities in 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 normal operation and output of the engine. Power supply guarantee.
Under normal circumstances, different models use different air filter replacement time, but when the air filter plug indicator lights up, the air filter must be cleaned. If the working environment is harsh, the replacement cycle of the air inside and outside the filter element should be shortened.
