Notes for changing diesel filter element

Dirty diesel filter not only reduces filtration efficiency, but also increases filtration resistance, resulting in insufficient oil supply and accelerating wear of precision parts: when paper filter element is used, it should be replaced regularly, and attention should be paid to the connection between both ends of the filter element and filter shell and cover

Face seal. Prevent the diesel oil from entering the filter element directly from both ends without filtration, or the diesel oil from leaking out. Air seeps in. Diesel filter element maintenance:

Diesel filter paper filter element, every 250 hours of work, should be cleaned in clean diesel. The filter life is about 500 hours. The service life of filter element is closely related to the cleanliness of fuel. When the surface of the filter element is dirty or the filter paper is deformed, it should be replaced in advance. When cleaning the filter element, a soft brush can be used to gently brush away the appearance of dirt in the cleaning diesel oil; In order to avoid dirt into the inner cavity, should be in advance with rubber or cork at both ends of the hole tightly blocked. Pay special attention to the reliable sealing of the end face and the wrong connection of the inlet and outlet tubing on the filter seat when installing the filter element, otherwise the filtering effect will be lost.

The function of the fuel filter is to filter out the harmful particles and water in the engine fuel gas system, so as to protect the nozzle of the diesel injection pump, the cylinder liner of the combustion cylinder, piston ring, etc., to reduce wear and avoid blockage.

The working pressure and the temperature of resistance to diesel oil are lower than that of the oil filter. But the requirement of filtration efficiency is higher than oil filter. The filter element of the diesel filter is mostly made of filter paper, but also of felt or polymer material. In addition to mechanical impurities in diesel oil filter, there is an important function is to filter water. The existence of water does great harm to the diesel engine oil supply system, such as corrosion, wear and jam. It can even worsen the combustion process of diesel in the combustion cylinder. The lower part of the filter is provided with a settling chamber. When water accumulates to a certain amount, the valve should be opened to discharge water. Sharf monorail crane diesel engine has two stages of diesel filter element, the first is the coarse filter, filter out impurities and water. The second stage is the fine filter, which can remove impurities of 5 cm and above to protect the diesel engine combustion system.
