摘要
介绍了某轮主机曲柄箱油雾浓度报警器的一种故障,该故障是因电路板上某一电容器断路所致.针对该故障当时的情况,利用运算放大器输入输出关系,采用由干电池产生一固定电压模拟输入信号的方法,使报警器恢复正常.
This paper introduces a fault of oil mist detector for certain main engine. This fault is resulted from turnoff of a capacitor in the printed circuit board. At that time, according to inputoutput relation of operational amplifier, a dry battery was used to produce a fixed voltage to simulate the input signal and then make the oil mist detector work normally.
