Abstract

The utility model relates to a novel vane of an electric fuel pump, wherein the vane teeth consist of two herringbone wings and are mounted between an inner ring and an outer ring at irregular interval; balancing holes are uniformly formed on the inner ring; and the included angle between the two herringbone wings ranges from 60 DEG to 120 DEG. The novel vane of the electric fuel pump has simple structure, reasonable design and low cost, can reduce liquid flow pulse, reduce the loss of the pressure of the pump oil during the rotating process of the vane, reduce the rotating speed of the electric fuel pump, and prolong the service life of the electric fuel pump.

Description

Electric fuel pump blade
Technical field
The utility model relates to a kind of electric fuel punp turbine pump blade, especially a kind ofly can reduce fluid pulse, increases the electric fuel pump blade of pump oil pressure.
Background technique
At present, in China's domestic electric fuel punp turbine pump blade structure, leaf-teeth are that homogeneous angular distributes, and flow area equates between leaf-teeth; In blade rotation, the pressure loss is bigger, and in the work of needs hyperbaric environment, its electric fuel punp needs rotating speed higher, and electric current is bigger, thereby influences the working life of electric fuel punp, has reduced working efficiency, has increased product cost.
Summary of the invention
The purpose of this utility model is to overcome the deficiency that exists in the above-mentioned technology, provides a kind of simple in structure, reasonable in design, with low cost, and can reduce fluid pulse, increases the electric fuel pump blade of pump oil pressure.
In order to achieve the above object, the technical solution adopted in the utility model is: leaf-teeth are made up of the both wings of " people " font, and unequal-interval is loaded between inner ring and the outer ring, evenly have equalizing orifice on the inner ring, and the two interplane angles of " people " font are 60 °~120 °.
The utility model has the advantages that:
Simple in structure, reasonable in design, with low cost, and can reduce fluid pulse, in the blade rotation process, reduced the loss of pump oil pressure, reduced the rotating speed of electric fuel punp, prolong the working life of electric fuel punp.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is a sectional view of the present utility model.
Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.
By Fig. 1-Fig. 2 as can be known, the utility model leaf-teeth 2 are made up of the both wings of " people " font, and unequal-interval is loaded between inner ring 3 and the outer ring 1, evenly have equalizing orifice 4 on the inner ring 3, and the two interplane angles of " people " font are 60 °~120 °.
Described leaf-teeth 2 are fitted between inner ring 3 and the outer ring 1.
The utility model in use, impeller is high speed rotating under rotor drives, and produces pressure difference in pump chamber, and drives fluid and suck from the electric fuel punp filler opening with certain pressure, oil outlet is discharged.Because leaf-teeth 2 are installed between inner ring 3 and the outer ring 1 by unequal-interval, and the two interplane adjustable angle of " people " font, can reduce fluid pulse like this, circulation area is inconsistent between blade, has increased the pump oil pressure.Equalizing orifice 4 has reduced the vibration that impeller produces in rotation process.

Claims (2)

1. electric fuel pump blade, comprise outer ring (1), leaf-teeth (2), inner ring (3) and equalizing orifice (4), it is characterized in that: leaf-teeth (2) are made up of the both wings of " people " font, and unequal-interval is loaded between inner ring (3) and outer ring (1), evenly have equalizing orifice (4) on the inner ring (3), the two interplane angles of " people " font are 60 °~120 °.
2. electric fuel pump blade according to claim 1 is characterized in that: described leaf-teeth (2) are fitted between inner ring (3) and outer ring (1).
