Problems solved by technology

For the copper parts of electrical connection, due to the existence of electrochemical corrosion, its service life is often affected, and it is difficult to meet the anti-corrosion requirements only by surface treatment technology
In recent years, carbon commutators with high scientific content have been used in the world to replace copper commutators to make methanol pumps, but such products are expensive, and it will take time to popularize them in large quantities.

Embodiment Construction

[0010] figure 1 Shown is an alcohol ether fuel pump, which includes a housing 4, a pump body and a motor in the housing 4, and a housing 2. The housing 2 is arranged outside the housing 4 and forms a jacket with the housing 4. The top of the housing 2 There is an oil outlet 13 connected with the fuel pipeline; the housing 4 is provided with a rubber pad 7, and the rubber pad 7 divides the housing 4 into two parts, the lower part is provided with a pump body, and the upper part is provided with a motor; Six through holes 12 are evenly distributed around the upper casing of the pump body, and the through holes 12 directly reach the oil outlet 13 through the jacket to form a fuel passage. The gap in the housing of the motor is set on the top of the rubber pad 7 and filled with cooling oil. The surface of the jacket between the inner shell and the outer shell, that is, the outer wall of the shell 4 and the inner wall of the outer shell 2, is coated with an alcohol-ether fuel-resi...

Abstract

The invention discloses an alcohol ether fuel pump comprising a shell, and a pump body and a motor which are arranged in the shell, and the motor is used for driving the pump body to work; the alcoholether fuel pump is characterized in that the alcohol ether fuel pump further comprises a housing arranged at the exterior of the shell, and a jacket is formed between the housing and the shell; the top of the housing is provided with a fuel outlet connected to a fuel pipeline; the shell is internally provided with a rubber pad, and the interior of the shell is divided into two parts by the rubberpad, wherein the lower part is provided with the pump body, and the upper part is provided with the motor; and a plurality of through holes are formed in the lower part of the rubber pad, the upper part of the pump body and the periphery of the housing, and the through holes get through the fuel outlet through the jacket so that a fuel channel is formed. The alcohol ether fuel pump is scientificand reasonable in structural design, and is not electrochemically corrosive to parts containing copper in the fuel pump; and the anticorrosion requirement of the fuel pump is met completely.

Description

technical field [0001] The invention belongs to the technical field of electric fuel pumps for automobile engines, in particular to a fuel pump suitable for alcohol-ether-containing fuels. Background technique [0002] The electric fuel pump is one of the key equipment of the automobile fuel supply system. The function of the fuel pump is to deliver the fuel stored in the fuel tank to the fuel pipeline of the injector. For the current fuel pump, there are many copper-containing parts in its internal structure, mainly the copper substrate of the commutator on the armature, the winding hook, the tail wire of the carbon brush, the connector of the electrical appliance, etc. For the copper parts of electrical connection, due to the existence of electrochemical corrosion, its service life is often affected, and it is difficult to meet the anti-corrosion requirements only by surface treatment technology. In recent years, carbon commutators with high scientific content have been u...
