摘要
建立了电控单体泵的物理模型,实现了电路、磁路和机械系统的一维耦合仿真。获得了单体泵驱动电路的电流波形、拉杆行程曲线和泵端压力曲线。进行了试验对比,表明电流驱动的波形相近,最大打开电流为13 A,保持电流为5 A;拉杆的最大行程为0.8mm;控制脉宽为3ms时,拉杆在最大行程的作用时间为2.4ms;泵端压力的波形有差异,最大压力相差9 MPa,针阀落座过程中压力曲线偏差较大。
A one-dimensional physical model of electronic unit pump （EUP） was built. Electronic, magnetic and mechanic subsystem coupled simulation was carried out. EUP drive waveform, horizontal plunger displacement curve and pump outlet pressure curve were made. A test experiment was done to verify the simulation result. It shows that the maximum drive current is 13 A and maintenance current is 5 A; the maximum horizontal plunger displacement is 0.8 mm; the actual effective opening time is 2.4 ms at plunger control pulse of 3 ms; the maximum pump outlet pressure difference is 9 MPa. There exists an obvious difference in needle closing process.
