Description

Technical Field

[0001] The utility model relates to the technical field of fuel filter elements, in particular to a fuel filter element with high efficiency filtration. Background Art

[0002] At present, most of the automotive engines are internal combustion engines, mainly using gasoline and diesel fuel. As a fuel, there must be certain requirements for the quality and cleanliness of the oil. Due to the refining and processing reasons, the finished fuel will definitely contain a certain amount of impurities, water and colloid. The function of the fuel filter is to filter out these impurities and water in the fuel and provide clean fuel for the engine. Since there are three precision parts in the diesel engine supply system, the cleanliness of the diesel is required to be high, and the colloid content in the diesel is high. If these colloids and impurities are not filtered out and enter the injection pump, it is easy to accelerate the wear of the precision parts, easy to clog, and reduce the life of the engine. At the same time, if the water, colloid, etc. in the fuel enter the cylinder, the combustible mixture will burn poorly and the power of the engine will decrease. A key component of the fuel filter for filtering colloids and impurities is the fuel filter element. The filtering effect of the fuel filter element represents the filtering effect of the entire fuel filter. Therefore, the design of the fuel filter element structure is crucial.

[0003] The existing fuel filter element has a good effect of filtering impurities, colloids and moisture, but there are still some problems: the main problem is that the fuel filter element is a consumable and needs to be replaced with a new one after a certain period of use, otherwise the filtering effect will be very poor, the filter paper has a low service life and is replaced frequently, but the hydrophobic net has a long service life and can be used for a long time with a low replacement frequency, while the filter paper and the hydrophobic net in the prior art are made into an integral structure. If the filter paper needs to be replaced, the entire fuel filter element assembly can only be replaced together with the hydrophobic net, which causes waste to the hydrophobic net and other structures and has a high cost of use.
