건설 기계 필터의 일반적인 문제를 매일 사용

Filter is an important part of construction machinery,which is including of oil filter, 연료 필터, 공기 정화기, 유압 오일 필터. Today we make a short introduction about the common problems which need to pay attention in daily using of construction machinery filter.

Common Problems Of 연료 필터:
1)Under what special circumstances, the oil filter element and fuel filter element need to be replaced?
Fuel filter is to remove iron oxide, dust and other magazines in the fuel, prevent the fuel system blockage, reduce mechanical wear, and ensure the stable operation of the engine.
정상적인 상황에서, the replacement cycle of engine fuel filter element is 250 hours for the first time and 500 hours thereafter. The specific replacement time should be flexibly mastered according to different fuel quality grades.When the pressure gauge of the filter element alarms or indicates that the pressure is abnormal, it is necessary to check whether the construction machinery filter has abnormal phenomenon. 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 abnormal phenomena. If so, it must be replaced.

2)Whether the 오일 필터 element filtration accuracy is higher, the better?
For an engine or equipment, an appropriate filter element filtration accuracy should achieve a balance between filtration efficiency and ash capacity. The use of high filtration accuracy of the construction machinery filter may shorten the service life of the filter element because of the low ash content of the construction machinery filter, thus increasing the risk of the oil filter element being blocked prematurely.

3)What is the difference between inferior oil, fuel filter and pure oil and fuel filter on equipment?
Pure oil and fuel filter can effectively protect equipment and extend the service life of other installations. Inferior oil and fuel filter can not protect equipment well, can not extend the service life of equipment, and will even worsen the service condition of equipment.

Common Problem Of 공기 정화기:
1)What is wearing down the engine?
There are three main forms of engine wear: corrosion wear, contact wear and abrasive wear. The results show that the abrasive wear of engine accounts for 60%-70% of the wear value. Engineering equipment usually works in very harsh environment. If there is no good filter element for protection, the cylinder and piston ring of the engine will wear out quickly. 그러므로, in order to improve the life of the engine, it is necessary to use the air filter element, fuel filter element and oil filter element with good filtering effect to reduce the abrasive wear of the engine.

2)What damage will maintenance cause to the engine if the air filter is damaged or not replaced in time?
Incorrect installation of the air filter element and failure to replace and maintain the air filter element in time will cause serious damage to your engine. The result is:Cylinder wear; Piston ring early wear; Insufficient equipment power; Increased maintenance costs; Serious will make the engine life greatly shortened, even scrapped.

Common Problem Of 유압 오일 필터:
1)Why does the quality of hydraulic oil filter element play a vital role in the performance of equipment?
For full hydraulic excavator hydraulic system throughout the excavator, it contains the main hydraulic oil tank, pump, control valve, the pipeline and perform a movement of oil cylinder, motor parts, such as the hydraulic components are by the precision machining, and they have higher request for the maintenance of hydraulic system, so the merits of the hydraulic oil filter is very important.

2)How to determine whether hydraulic components are damaged by regularly checking the replacement of hydraulic oil filter element?
When replacing the hydraulic oil filter element, please check whether there are metal particles or debris at the bottom of the construction machinery filter. If there are copper or iron chips, it indicates that the hydraulic pump, hydraulic motor or valve may be damaged or will be damaged. If there are rubber, it indicates that the hydraulic cylinder seal is damaged.
