Arc tingia wheel electricity spouts fuel pump

(B /) the utility model discloses an arc tingia wheel electricity spouts fuel pump, including the impeller, the impeller has the blade that the circumference was laid, its characterized in that: the blade is converted into the V type in the impeller shaft direction, the blade surface of blade is designed for the cambered surface, is equipped with the lath between the bottom of adjacent blade, and blade V type book is connected at the lath both ends, and the height of lath is the half the of blade height, the right side terminal surface of impeller leans on the hole position to set up annular shallow slot, circumference equipartition pore and bump in the annular shallow slot region, and pore and bump are crisscross to be set up, and the top surface of bump maintains an equal level with the right side terminal surface height of impeller. The utility model discloses comparing the car fuel pump impeller of traditional linear type blade, having the advantage that increases the oil pump flow, reduces oil pump operating current and noise, oil groove and oil groove hole are not established to impeller both sides terminal surface simultaneously, and simple structure reduces impeller both sides terminal surface loss of pressure, improves the pump internal efficiency.
