Embodiment Construction

[0015] The present invention is described in further detail now in conjunction with accompanying drawing. These drawings are all simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, so they only show the configurations related to the present invention.

[0016] see Figure 2 to Figure 4 , the vane 100 of a DC electric fuel pump shown in the figure is a cuboid structure, the front side 130 of the cuboid structure is arranged with ribs 110 at intervals, and oil drain grooves 120 are arranged between the ribs 110 . The thickness A1 of the cuboid structure is greater than 1 mm, and the distance B1 between the top of the rib 110 and the top 140 of the cuboid structure is greater than 1 mm.

[0017] see figure 1 , the vane 100 is disposed in the slot 210 of the vane pump rotor 200 , and the vane 100 can reciprocate in the slot 210 . When the rotor 200 rotates, the blade 100 is always in contact with the inner wal...

Abstract

The invention discloses a blade of a direct-current electric gasoline pump. The blade is in a cuboid structure, rib strips are distributed on the front side of the cuboid structure, and oil discharging grooves are formed among the rib strips; the blade is characterized in that the thickness of the solid cuboid is greater than 1 mm, and the distance from the top end of each rib strip to the top end of the cuboid is greater than 0.1 mm. The thickness of the blade ensures that a blade main cutting edge has high abrasion resistance capability, and only when the blade main cutting edge is abraded unitl the position of the rib strips, the rib strips are contacted with the cylindrical inner side face of a pump body; by using the structre above, the service life of the blade is prolonged and the inner leakage of a blade pump is reduced.

Description

technical field [0001] The invention relates to the field of engineering machinery refueling, in particular to blades of DC electric refueling pumps. Background technique [0002] At present, the blades of the existing DC electric fuel pump have the following two structural modes: [0003] The first structure mode is: the blade is made of a solid cuboid. Ribs are arranged on the front of the cuboid, and oil drain grooves are arranged between the ribs. The top of the rib is flush with the top of the cuboid. Since the position of the contact line between the main cutting edge and the inner surface of the cylinder of the pump body is constantly changing, when the rib contacts the inner surface of the cylinder of the pump body, the oil discharge groove will form a leak point. If the distance between the top of the rib and the top of the cuboid is too close, the rib will contact the inner surface of the cylinder of the pump body to cause leakage when the cuboid is worn. [00...
