Abstract

The invention provides a novel two-stage fuel filtering system. The novel two-stage fuel filtering system comprises a coarse filter assembly, a fuel delivery pump and a fine filter assembly, wherein the coarse filter assembly comprises a hand pump filter base and a coarse filter tank body which are mutually connected, the hand pump filter base is used for sucking and pumping fuel in a fuel tank into a pipeline, and the coarse filter tank body is used for filtering out impurities and air in the fuel for the first time; the fuel delivery pump is connected with a coarse filter fuel inlet of the coarse filter assembly, and used for pumping and pressing the fuel in the pipeline; and the fine filter assembly comprises a fine filter base and a fine filter tank body and is used for filtering the fuel output from the fuel delivery pump for the second time, the fine filter base and the fine filter tank body are connected, a fuel inlet of the fine filter assembly is connected with the fuel delivery pump, and a fuel outlet of the fine filter assembly is connected with an engine fuel jet device. The novel two-stage fuel filtering system is reasonable in arrangement and compact in structure, effectively prevents gas in the fuel from entering an engine, and accordingly, avoids the phenomenon of insufficient fuel supply caused by the fact that lots of gas enters the engine, and therefore, the engine is prevented from generating insufficient power or even stop due to the problems.

Description

technical field [0001] The present invention relates to the field of fuel filter systems, more specifically, to a novel two-stage fuel filter system. Background technique [0002] Most of the current fuel filter systems use a structure in which the coarse filter tank, the fuel delivery pump, and the fine filter tank are connected in series. The coarse filter tank is arranged at the front end of the oil transfer pump, and is mainly used for filtering larger particles and water, preventing large particles from wearing out the oil transfer pump, which is beneficial to protect the oil transfer pump. The fine filter tank is arranged at the rear end of the oil delivery pump, mainly filtering smaller particles. As the emission requirements become higher and higher, the quality of oil products is getting better and better, and the filtration accuracy of the filter materials of the coarse filter tank and the fine filter tank is getting higher and higher, which makes the air permeabi...
