[Abstract]:The fuel pump is the key component of auto fuel system, EFI (electronic fuel injection) is an important component in the system, the fuel pump performance affects the engine starting performance, operation state, emission etc. in energy saving and environmental protection has increasingly emphasized the automobile and operational flexibility, ride comfort, the safety of the passengers today, as the electric fuel pump is the important part of the engine, has a great influence on the performance of the engine. The problem of automobile fuel pump noise is one of the main factors affecting vehicle ride comfort, the noise of the fuel pump and fuel pump structure about the problem, to solve these problems, this paper researches on the fuel pump and noise oil pump efficiency, has important significance for design of automobile fuel pump structure technology.
In this paper, the PULSE Labshop software of Danish BK company and FLUENT numerical simulation software are used to study the fuel pump impeller units with different structures. The main research works are as follows:
(1) the noise test of the oil pump. The PULSE Labshop software of Denmark BK company was used to simulate the actual working condition in the semi anechoic room to measure the noise of the oil pump, and the factors causing the noise of the fuel pump of the complaint part were determined through geometric parameter test.
(2) the mechanism of the impeller noise is studied theoretically, and it is determined that the impeller structure is closely related to the rotating noise and the eddy noise.
(3) building three-dimensional simulation model of pump impeller unit; simulation analysis of fuel pump impeller unit with different structure by using CFD software FLUENT; analysis of different structure parameters of the fuel pump includes the number of blades were 9,18,47,54 four kinds of structural parameters of the flow field and noise power level distribution, and there were 90 leaf level degrees, 45 degrees, 30 degrees and three different blade distribution of flow field and noise sound power level distribution;
(4) the results of simulation analysis are analyzed. The simulation results show that the uniformity of velocity field distribution and the rotation noise value after vector synthesis should be taken into account in reasonable design of impeller angle of oil pump.
