High-durability automobile fuel filter

Abstract

The invention discloses a high-durability automobile fuel filter. The high-durability automobile fuel filter comprises a filter cavity and a steel plating shell, wherein the filter cavity is fixedly installed at the bottom of the steel plating shell through a first threaded interface, a first installation frame body and a second installation frame body are respectively embedded in the filter cavity, and a first filter screen and a second filter screen are respectively embedded in the first installation frame body and the second installation frame body. According to the filtering cavity provided by the invention, the pre-filtering effect of the filter is realized through the installation frame bodies and the filter screens, the filtering effect of the filter is ensured, so that the filter can be recycled, the operation cost is reduced, the durability of the filter is increased, the filtering performance of the filter is further enhanced through a filtering cotton sleeve by a filtering main body, more impurity particles accumulated in the filter after long-time operation are avoided or reduced, the entrance of large-particle impurities is effectively reduced, and the durability of the filter is improved.

Description

technical field [0001] The invention relates to the technical field of auto parts, in particular to a highly durable auto fuel filter. Background technique [0002] Fuel filter (Fuel filter) has three types: diesel filter (Diesel filter), gasoline filter (FuelFilter) and natural gas filter (Gas filter). Water and unclean matter, to ensure that the precise parts of the fuel system are free from wear and other damage; [0003] The fuel filter is connected in series on the pipeline between the fuel pump and the fuel inlet of the throttle body. The function of the fuel filter is to remove solid impurities such as iron oxide and dust contained in the fuel to prevent the fuel system from Blockage (especially fuel injectors), reduce mechanical wear, ensure stable engine operation, and improve reliability. The structure of the fuel injector is composed of an aluminum shell and a bracket with stainless steel inside. The bracket is equipped with high-efficiency filter paper. The fil...

Problems solved by technology

[0004] Although the existing patent (notification number: CN109854425A) discloses a kind of automobile fuel filter, comprises outer sealing ring, sealing ring mounting plate, filter element front cover, filter element, filter element rear end cover, leaf spring, housing, filter tube, Inner sealing ring and threaded cover plate, but in the process of realizing the present invention, the inventor finds that there are at least the following problems in the prior art that have not been solved;

[0005] The following defects still exist: 1. The overall structure of the filter is relatively simple, and the filtering performance is relatively simple, so it cannot better filter the impurities in the fuel, and after a long time of operation, it is easy to cause the molecules of the filter material to diffuse, making the fuel oil The impurities in the filter accumulate inside the filter mechanism, which reduces the filter effect and the life of the filter mechanism; Deformation occurs, which not only leads to the filtering effect of the filter, but also reduces the oil passing efficiency of the filter, cannot better guarantee and maintain the working form of the filter, and reduces the durability of the filter; 3. Basically, the filter can only perform one-time flow filtration operation, which not only increases the filtration load of the filter mechanism, but also increases the strain of the filter mechanism, and cannot better guarantee the filter after a long time of operation. quality, so this needs to be improved to address the above issues
