Description

Parallel multistage fuel filter Technical Field The utility model relates to the technical field of fuel filtration, in particular to a parallel multistage fuel filter. Background With the continuous development of internal combustion engine technology, the fuel system has put higher demands on the cleanliness of fuel. The fuel is often mixed with impurities such as metal scraps, dust, moisture and the like, and if the impurities are not sufficiently filtered to enter the combustion chamber of the engine, the fuel injection device is blocked, the abrasion is aggravated, and even the performance of the engine is reduced or damaged. Therefore, the fuel filter is used as a key component for guaranteeing the cleanliness of a fuel system, the performance of the fuel filter is directly related to the stable operation and the service life of an engine, and the fuel filter has important application value and research significance. The utility model provides a parallel multistage fuel filter, which aims to optimize the traditional fuel filtering path, improve the overall filtering efficiency and meet the use requirement of a high-performance engine. The existing fuel filter generally adopts a single filter cartridge structure, and after fuel enters the filter shell through the oil inlet, the fuel intercepts and filters impurities through the filter material of the filter element and then outputs clean fuel through the oil outlet. In some constructions, the cartridge is secured in the center of the housing, and fuel is typically discharged from the exterior of the cartridge to the interior or from the interior to the exterior and then to the downstream system. Such structures generally have the advantages of compact size, convenient manufacture, and simple structure, and are widely used in conventional vehicles and low-power devices. However, when the existing fuel filter adopting the single filter cartridge structure is used for treating high-flow fuel or high-pollution fuel, the problems of lower filtering efficiency, easy blockage of the filter element and shortened service life exist, and particularly under continuous operation or complex working conditions, the single-stage filter element is difficult to simultaneously consider the filtering precision and the flow stability, so that part of impurities cannot be effectively trapped, the stability of a downstream fuel injection system and the working efficiency of an engine are influenced, and the improvement of the fuel filtering structure is needed to improve the filtering effect. Disclosure of utility model In order to overcome the defects, the utility model provides a parallel multistage fuel filter, which aims to solve the problem that the fuel filter has poor filtering efficiency through a single filter cartridge. In order to achieve the aim, the utility model adopts the following technical scheme that the parallel multistage fuel filter comprises a filter cartridge shell, wherein a connecting component is arranged on the outer wall of the filter cartridge shell, one end of the filter cartridge shell is fixedly connected with a top cover, and a pipeline component is arranged in the top cover; the pipeline assembly comprises an oil outlet pipe, one end of the oil outlet pipe is fixedly connected inside a top cover, a connecting pipe is fixedly connected inside the top cover, an oil inlet pipe is fixedly connected inside the connecting pipe, a plurality of filter cores are slidably connected inside a filter cartridge shell, a maintenance cover is arranged at the other end of the filter cartridge shell, and a sealing assembly is arranged between the maintenance cover and the filter cartridge shell. As a further description of the above technical solution: The connecting component comprises a fixing frame, one side of the fixing frame is fixedly connected to the outer wall of the filter cylinder shell, and the filter cylinder shell is symmetrically arranged and fixedly connected to one side of the fixing frame.
