1故障现象全血吸样量少、速度比正常时慢。2分析及检修该设备没有电路原理图,仅有系统管路流程图。首先仔细检查稀释部分外观管路看有否泄漏、渗漏或堵塞,发现旋转阀V1有微量渗漏液。拆开后清洗并更换内垫圈,漏液现象消除,但吸样速度仍无明显改善,故障依旧。接着利用仪
1 Failure phenomenon Whole blood has less sample and the speed is slower than normal. 2 Analysis and Maintenance The equipment does not have a circuit diagram, only the system piping flow chart. First of all, carefully inspect the dilute part of the appearance of the pipeline to see if there is leakage, leakage or blockage, found that the rotary valve V1 trace leakage. After the dismantling, the inner gasket was cleaned and replaced, and the leakage phenomenon was eliminated. However, the rate of aspirating the sample still did not improve significantly and the failure persisted. Then use the instrument
