柯达洗片机显影加热的故障判断与维修

Judgment and Maintain for Break Down of Heating Develop with Kodak Develop Film Machine

柯达 M7B洗片机的显影加热系统由两部分组成 ,分别为显影温度控制电路和显影过温探测电路。由于洗片机需连续运行以及工作环境的恶劣 ,电路部分尤以显影温度控制部分的故障率较高。故障现象均相同 。

Developing heating system of Kodak develop film machine is constituted by two parts, which are temperature control electric circuit and developing temperature monitor electric circuit. Because develop film machine needs consecutive circulate and its work environment is bad, it has higher breakdown ratio in temperature control part, particularly in developing temperature control part. Above all, the breakdown's phenomenon is same; the breakdown's reason is different.
