Embodiment Construction

[0014] The present invention is a high-pressure flow environment-friendly integrated electric fuel pump integrated housing processing technology, the steps are as follows: a. Cold heading the material to obtain the integrated shell rough; b. Solid solution the integrated shell rough in step a. For processing, put the integrated shell rough blank into a high-temperature furnace at a temperature of 1150°C-1250°C, keep it warm for 1.5h-2h, and then put the integrated shell rough blank into water for express cooling; c. The rough blank of the integrated shell is subjected to precision machining, that is, the fuel pump placement cavity and the fuel inlet and outlet passages on it are processed by a drilling machine and a grinder, and the integrated shell blank is obtained; d. The rough blank of the integrated shell that has completed the precision machining is shot blast treatment; e, activate the integrated shell blank that has been shot blasted, the activation temperature is 200°C...

Abstract

The invention relates to a high-pressure flow environment-friendly integrated electric fuel pump, in particular to a processing technology of an integrated shell of the high-pressure flow environment-friendly integrated electric fuel pump. The technical scheme is as follows: the processing technology of the integrated shell of the high-pressure flow environment-friendly integrated electric fuel pump comprises the following steps: a, cold heading to obtain an integrated shell rough blank; b, carrying out solid solution treatment on the integrated shell rough blank in the step a; c, finishing the integrated shell rough blank; d, carrying out shot blasting treatment on the integrated shell rough blank; e, activating the integrated shell blank; f, performing non-metal element composite infiltration on the integrated shell blank; g, insulating the integrated shell blank; h, cooling the integrated shell blank; i, painting anti-corrosive primer to the surface of the integrated shell blank toform a primer film; and j, coating high-solid paint on the integrated shell blank to obtain a finished product. By adopting the scheme, the processing technology of the integrated shell of the high-pressure flow environment-friendly integrated electric fuel pump can improve the hardness and achieve good corrosion resistance.

Description

technical field [0001] The invention relates to a high-pressure flow environment-friendly integrated electric fuel pump, in particular to a processing technology for a high-pressure flow environment-friendly integrated electric fuel pump integrated housing. Background technique [0002] Fuel pump is a term in the auto parts industry. It is one of the basic components of EFI automobile fuel injection system. The function is to suck the fuel out of the fuel tank, pressurize it, and send it to the fuel supply pipe to connect with the fuel injector. [0003] In relatively special working conditions, in order to increase the pressure and flow of the fuel system, several fuel pumps are usually connected through plastic conduits. This method uses conduit connections. Not only is the connection process cumbersome, but also the conduits are prone to leakage. Its pressure is unstable. And the fuel pump needs to work continuously, otherwise its fuel supply pressure will be unstable....
