CC—180型自动血球计数器是日本东亚公司近年推出的较新式产品。它由7个设定程序支持,可同时测量包括血小板在内的8个项目。该机在使用一段时间后,有时会出现按下“count”键后,探头不进样,或进样正常,CRT 显示“00”。通过检查,我们发现这种故障大都是由于控制样品通道通,断的电磁阀线圈断电后,衔铁落不下来,以致将通道胶管顶住,从而造成管路不通。进一步分析发现,衔铁落不下来多是由于以下原因造成的:电磁阀的阀体上盖,使用一段时间后积下了微量剩磁,对衔铁有一定的吸
CC-180 automatic blood cell counter is Japan’s East Asian companies introduced in recent years, newer products. It is supported by seven setup programs that can measure up to eight items including platelets simultaneously. After the machine is used for a period of time, sometimes the “count” key is pressed, the probe does not inject or the injection is normal, and the CRT displays “00”. Through inspection, we found that most of this failure is due to the control of the sample channel, the solenoid valve coil is off, the armature can not fall down, so that the channel hose to withstand, resulting in pipeline unreasonable. Further analysis found that the armature can not fall down mostly due to the following reasons: Solenoid valve body cover, the use of a period of time after the product of a small amount of residual magnetism, the armature has a certain degree of suction
