Example Embodiment
[0028] Example 1
[0029] like figure 1 As shown, a low-noise vortex fuel pump includes a fuel pump body and an oil intake assembly arranged at the oil inlet end of the fuel pump body, wherein the oil intake assembly includes a pump cover 1, an impeller 2 and an impeller seat 3 arranged in sequence from outside to inside ;
[0030] like figure 2 and image 3 As shown, the upper and lower end surfaces of the impeller 2 are oppositely provided with a plurality of arc-shaped blade groups 21. The arc-shaped blade group 21 includes an arc-shaped upper blade and a lower blade. The lower edge of the upper blade and the upper edge of the lower blade Fixed connection, the adjacent arc-shaped blade groups 21 form two arc-shaped channels in opposite directions, the fluid flows from the pump cover 1 through the arc-shaped channels on the impeller 2, and the interference is alleviated, and finally enters through the impeller seat. in the fuel pump body.
[0031] like figure 2 As sh...
