Embodiment Construction

[0040] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, but not as a limitation of the present invention.

[0041] like figure 2 , image 3 As shown, a fuel pump assembly capable of absorbing iron-containing impurities includes a fuel tank (not shown in the figure), a fuel storage barrel 1 disposed in the fuel tank, and a fuel pump 11 disposed in the fuel storage barrel 1 A filter (not shown in the figure) is arranged at the bottom of the fuel pump 11, and a dust collection box 2 is arranged at the lower end of the outer wall of the oil storage barrel 1.

[0042] In the embodiment of the present invention, a filter is provided at the bottom of the fuel pump 11 to remove fine impurities in part of the fuel, and a debris box 2 is provided at the lower end of the outer wall of the fuel tank 1 . Since the density of iron-containing impurities is heavier than that of fuel, they are generally deposited a...

Abstract

The invention discloses a fuel pump assembly capable of absorbing iron-containing impurities, comprising a fuel tank; an oil storage tank, the oil storage tank is arranged in the fuel tank; Inside the oil storage barrel; a filter, the filter is arranged at the bottom of the fuel pump; and a debris collection box is arranged at the lower end of the outer wall of the oil storage barrel. The invention absorbs the impurities in the fuel tank through the magnet, can improve the cleanliness of the fuel, prevents hard particles containing iron from entering the oil storage tank, thereby protecting the fuel pump body and increasing the service life of the fuel pump.

Description

technical field [0001] The invention relates to a fuel pump assembly, in particular to a fuel pump assembly capable of absorbing iron-containing impurities. Background technique [0002] The fuel system is an important part of the vehicle chassis, and its function is to store and deliver fuel. The fuel pump draws fuel from the fuel tank, and sends the fuel to the fuel injector in the engine compartment through the delivery pipeline, and the fuel injector injects the fuel under a certain pressure into the combustion chamber for combustion. The cleanliness of the fuel will greatly affect the fuel pump and some other peripheral parts. [0003] The sources of impurities in fuel oil come from two aspects. One is from the fuel itself. Since most of the fuel oil is transported in metal turnover containers, metal impurities may be mixed in due to corrosion and other reasons. The other is the impurities in the fuel tank itself, especially For iron fuel tanks (compared to plastic fu...
