机型:德国Fresenius A2008C型 故障现象一:透析、热消毒时正常。冲洗时流量不足。调整冲洗流量控制电位器变化不大,影响冲洗。 故障分析:影响流量有流量控制电路和水路管道阻塞两种原因。透析、热消毒流量正常,根据水路流向量分析,水路阻塞可能性小。故障出在流量控制电路。 检修:冲洗流量控制电路由LP194齿轮泵控制和LP276逻辑电路两块电路板组成。检修
Model: Fresenius A2008C, Germany Symptom 1: Normal dialysis and thermal disinfection. Insufficient flow during flushing. Adjusting the flushing flow control potentiometer does not change much and affects flushing. Fault analysis: There are two reasons that affect flow: flow control circuit and water pipeline obstruction. The dialysis and thermal disinfection flow rate is normal. According to the waterway flow vector analysis, the waterway blockage is less likely. The fault is in the flow control circuit. Maintenance: The flushing flow control circuit consists of LP194 gear pump control and LP276 logic circuit consisting of two circuit boards. Overhaul
