摘要
介绍了给水泵汽轮机电液控制调速系统(MEH)改造的具体情况及改造后运行过程中出现的不易挂闸故障。经过试验分析,找出了MEH系统故障的原因,给出了优化措施,解决了MEH改造中的问题。
The particular case of the micro electro hydraulic control system(MEH) reformation of the boiler feed pump turbine and the fault of difficulty in latch-on occurred in operation after the reformation were introduced.According to the experimental analysis,the reasons of the MEH system fault were found out,and the optimizing measures were given,the problems in MEH reformation were solved.
