Diesel filter element is one of the important components to ensure the oil quality of diesel engine. High quality diesel filters can effectively block the dust and moisture entrained in diesel, and can effectively prolong the service life of fuel injection pumps, diesel nozzles and other filter elements. Therefore, it is very important for the engine to replace the diesel filter element in time. This article will introduce the function of diesel filter element and the importance and precautions of replacing diesel filter element in time. For reference only.
1. Function of diesel filter element
Diesel filter element is one of the important components to ensure the fuel quality of excavator engine. It is to protect the engine fuel injection pump, injector, cylinder liner, piston ring, etc. by filtering out harmful particles and moisture in the engine fuel system, so as to reduce wear and avoid problems such as blockage. It can be said that the diesel filter element plays a vital role in the high-pressure common rail engine.
2. Importance and precautions of replacing diesel filter element
1) The diesel filter element is to remove the iron oxide, dust and other magazines in the diesel, prevent the diesel system from blocking, reduce mechanical wear and ensure the stable operation of the engine.
2) Generally, the replacement cycle of engine diesel filter element is 250 hours after the first operation, and then every 500 hours after that.
3) When the filter element pressure gauge gives an alarm or indicates abnormal pressure, it is necessary to check whether the filter is abnormal. If yes, it must be replaced.
4) When there is leakage or cracking deformation on the surface of the filter element, it is necessary to check whether the filter is abnormal. If yes, it must be replaced.
