故障现象:接通电源与反渗水,旋钮置于清洗位后,绿指示灯亮,电导度指示灯闪烁性地低报警;垮膜压(TMP)、动脉压、静脉压指示针偏向负方向,并且不可调;旋钮置于透析位时,血漏报警,血漏旋钮不可调,透析液旁路,打开电脑开关,所有电脑面板指示灯都亮,数字显示七段都亮,但亮度比正常时暗,并伴有警报声。 故障分析:根据故障现象,考虑其原因:1.几个问题的巧合现象,如:电路接触不好,有误报警等情况。2.单纯性的电路问题。
Symptom: After turning on the power supply and reverse osmosis water, the knob is placed in the cleaning position, the green indicator light is on, the conductance indicator light flashes low alarm; the declamping membrane pressure (TMP), arterial pressure, and venous pressure indicate that the needle is biased to the negative direction, and Not adjustable; when the knob is placed in the dialysis position, the blood leak alarm, the blood leak knob is not adjustable, the dialysate bypass, turn on the computer switch, all computer panel lights are on, the digital display seven segments are bright, but the brightness is darker than normal Accompanied by an alarm sound. Failure analysis: According to the phenomenon of failure, consider the reasons: 1. Coincidence of several issues, such as: circuit contact is not good, false alarms and other conditions. 2. Simple circuit problems.
