| Abstract: | Based on the analysis of the water shortage caused by feed pump switching in boiler steam drum, the main reason of the fault is ascertained to be mal-operation, while the non-return valve and electric gate valve also present fault. In this paper, it points out correct operation steps and attentions that should be paid to switch feed pump, and suggestions are given for the choosing of electric gate valve controlling element and the design of feed pump entrance pipe. |
