摘要
针对现有汽车油泵电子控制器不足,提出了改进设计的方案。改进后的新型汽车油泵控制器的特征:油泵在供油时的电磁铁振幅大、油流量大;在油压达到设定值时,由磁场检测电路命令电磁铁停止运动,电路关断彻底,油压维持时间长;电磁铁运动控制容易、功率管发热小、电路节能高效,特别适用于汽车电子油泵及其他泵类控制。
This article presents programs designed to improve the existing auto pump electronic controller.The characteristics of new car pump controller:The electromagnet amplitude and oil flow is large in oil pump when oil supply time;when the hydraulic pressure reaches the set value,the magnetic-field detection circuit commands the solenoid to stop motion,Circuit shut down completely,hydraulic maintain a long time;the electromagnet movement control is easy,power tube heat is small,energy-saving of electric circuit is efficient,especially suitable for the fuel pump and pump control.
