Analysis of electromagnetic force and power loss characteristics on high-speed solenoid valve of electric-controlled booster pump

In order to further study the electromagnetic force and energy consumption characteristics of the solenoid valve of the electronic-controlled booster pump, a 3D static magnetic field simulation model of the high-speed solenoid valve of the electronic-controlled booster pump was established by using the finite element method, and the accuracy of the model was verified by the experimental data. Through numerical simulation analysis, the characteristics of the electromagnetic force and power loss of the solenoid valve of the electric-controlled booster pump were studied by driving current and structural parameters (the number of coil turns, magnetic pole′s radius, working air gap), and the weight influence of each parameter on the electromagnetic force and power loss of the solenoid valve was obtained and the quantitative analysis was made. The results show that the influence of the radius of major and vice magnetic poles on electromagnetic force accounts for 38.15%, followed by the driving current which accounts for 31.08%, the number of coil turns which accounts for 17.06%, and the working air gap which accounts for 13.71%. From the perspective of power loss, the ratio of driving current, coil turns, radius of major and vice poles and working air gap of electric-controlled booster pump solenoid valve were analyzed. The ratio of coil turns(54.85%) is the highest, followed by the driving current(44.99%), and the minimum ratio of the radius of major and vice magnetic poles and working air gap is only 0.16%.
