汽车油泵电子控制器的改进设计

Improved design of car's pump electronic controller

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.
