故障现象:血透机开机较长时间后不能达到正常所需温度,低温指示灯始终亮。故障分析:引起血透机低温报警的主要原因有以下几种;1血透机加热棒损坏。要判断加热棒是否损坏可测量加热棒电阻值,打开血透机后面板,找到接线端子ＴＢ2的5、6二脚,测得电阻值为14Ω则电热棒完好,如果电
Symptoms: The hemodialyzer cannot reach the normal required temperature after being turned on for a long time, and the low temperature indicator is always on. Failure Analysis: The main causes of low temperature alarm hemodialysis machines are the following; 1 Hemodialysis machine heating rod damage. To determine whether the heating rod is damaged, measure the resistance value of the heating rod, open the back panel of the hemodialysis machine, and find the feet 5 and 6 of the terminal TB2. The measured resistance value is 14Ω. Then the heating rod is in good condition.
