秦二厂装卸料机典型故障分析与改进

Typical Fault Analysis and Improvements of the PMC in Qinshan Phase Ⅱ

秦二厂3、4号机组采用PLC可编程控制器进行装卸料机的逻辑控制,1、2号机组也于2014年按3、4号机组控制方式完成了原装卸料机控制系统的升级改造。本文选取安装调试、历次大修装卸料机维护过程中遇到的典型故障为例,通过理论分析和操作试验等方法对这些故障进行处理。随着现场工作的开展,成功解决了这些典型故障,并对其今后的维护与改进提出了建议。通过本文的论述,希望能对其它在建核电厂或已投入运行的核电厂和设计单位有一定的借鉴和指导意义。

The PMC of Qinshan Unit 3＆4 used PLC control system, and Qinshan Unit 1＆2 renewed it＇ s control system in 2014.This paper will focus on the typical faults in the PMC, which were handled by theoretical analysis and operation tests. With carrying out the work at the site, we have solved these typical faults successfully, and provided solutions to maintenance of the PMC. We hope that this paper will have important reference value and guidance significance for the other nuclear power plants and designing institutions.
