IL公司生产的“MCA全自动微量生化分析仪”结构复杂,给维修带来一定困难。据悉,目前国内各大中医院共有数十台该种仪器,利用率不到50％。因此交流维修经验有一定的普遍意义。故障现象当仪器进入分析测试状态时,转盘一直不停地高速旋转,仅当按面板上的Stop键时才停止。整机的自动分析测试中止。故障分析输入维修磁带,测试转盘速度,发现在加温时(In-cubate)转盘速度RPM高达4000RPM,超过正常值的40倍,因此可确定故障为转盘速度失控。马达逻辑电路控制参看维修资料。
IL company’s “MCA automatic micro-biochemical analyzer,” the complexity of the structure, to bring some maintenance difficulties. It is reported that, at present, there are dozens of these kinds of instruments in various major hospitals in China, with a utilization rate of less than 50%. Therefore, exchange and maintenance experience has some general significance. Symptom When the instrument into the analysis test state, the turntable has been constantly rotating at high speed, only when pressing the Stop button on the panel to stop. Automatic analysis of the machine stop testing. Failure Analysis Enter the maintenance tape to test the turntable speed and found that the turntable speed RPM is up to 4000 RPM in the in-cubate, which is more than 40 times the normal value, so it can be determined that the failure is the turntable speed is out of control. Motor logic control see maintenance information.
