故障现象 电导率低报警不停。接上透析液测试仪测量电导率 ,表针在低 (大约 - 3% )处抖动。分析检修 一般发生电导率低的故障 ,有以下 3种可能(1)透析浓缩液桶与主机连接不好 ,有气泡吸入。(2 )电路中Ｆ2保险丝烧毁。(3)比例泵故障。前两种故障比较直观 ,经观察、测量并无问
Symptoms Low conductivity alarms stop. Connect the dialysate tester to measure the conductivity and the hands will dither at a low (about - 3%). Analysis and maintenance Generally, there is a failure with low conductivity. The following three possibilities are possible. (1) The dialysis concentrate barrel is not connected to the host well, and there is a bubble inhalation. (2) The F2 fuse in the circuit is burned. (3) Proportional pump failure. The first two kinds of faults are more intuitive and no observations or measurements are made.
