WR—Ⅱ型微波治癌机是对恶性肿瘤进行控温热效应治疗和对多种疾病进行热效应理疗的新型医疗仪器。该机利用微机控制,能自动记录测温数据,绘制测温曲线,存储治疗档案,使用方便,在我国大中型医院得到广泛应用。 故障现象 加高压无微波输出,同时PC机监视器信号完全丢失,出现“白屏”。 分析检修 把PC机从机器上脱离,单独供电操作,工作正常。说明升高压时监视器上信号突然消失,是由于主机其他电路故障引起。
The WR-II type microwave cancer treatment machine is a new type of medical instrument that controls the thermal effects of malignant tumors and performs thermal effects therapy on various diseases. The machine uses microcomputer control, can automatically record temperature data, draw temperature curves, store treatment files, easy to use, widely used in large and medium-sized hospitals in China. Symptoms High voltage and no microwave output are added. At the same time, the PC monitor signal is completely lost and a “white screen” appears. Analysis and maintenance The PC is detached from the machine, and the power supply is operated independently. It is working normally. The signal on the monitor suddenly disappears when the voltage is increased, which is caused by the failure of other circuits in the host.
