摘要
通过对联锁逻辑程序、SIS输出继电器回路、电气控制回路的详细分析,以在人机界面中加入软按钮的方法,解决现场操作柱缺少主泵/辅泵转换开关的设计缺陷,满足了工艺要求,节约了成本、时间。
Analyze in detail the interlocking logic program, SIS output relay circuit and the electrical control circuit. Add the soft buttons on the man-machine interface to solve the design defect of the main pump/auxiliary pump transfer switch which is lack in the on-site operation column. The revamping meets the process requirements, saves cost and time.
