Electronic fuel pump system of large engine

Abstract

The invention discloses an electronic fuel pump system of a large engine. The electronic fuel pump system of the large engine comprises a supporting plate and a fixing block, wherein the supporting plate is an L-shaped plate, an annular baffle is fixed to the upper end of the bottom of the supporting plate, a supporting pad is glued to the upper end of the bottom of the supporting plate, and an electronic pump body is placed at the upper end of the supporting pad; and the side wall of the electronic pump body is connected with the side wall of the supporting plate through a plurality of connecting springs, a through groove is formed in the bottom of the supporting plate in a penetrating mode, the electronic pump body is connected with a control device, a limiting device is arranged in the fixing block, and the control device comprises a fuel outlet pipe fixed to the upper end of the electronic pump body. The electronic fuel pump system of the large engine has the following advantages: before the engine operates, normal circulation of a fuel way can be guaranteed by controlling operation of the electronic pump, and the situation that the engine cannot be started due to the fact that fuel cannot be pumped smoothly due to a low rotating speed of a fuel delivery pump in the starting stage of the engine can be avoided, so that normal operation of the engine can be guaranteed.

Description

technical field [0001] The invention relates to the technical field of engines, in particular to an electronic fuel pump system for large engines. Background technique [0002] An engine is a machine that can convert other forms of energy into mechanical energy, including internal combustion engines, external combustion engines, jet engines, electric motors, etc. For example, internal combustion engines usually convert chemical energy into mechanical energy. Engines are suitable for both power generating devices and It can refer to the entire machine including the power unit, mainly used in construction machinery, data centers, power generation, hotel and hospital backup power supply and other fields. The electric fuel pump continuously sucks the fuel out of the fuel tank to provide the fuel system with specified pressure and flow. a fuel oil device; [0003] In the start-up phase of traditional engines, the fuel pump often fails to pump fuel smoothly due to the low speed o...
