摘要
阐述巴基斯坦某换流站消防水系统,消防管道地埋式、雨淋阀水喷雾流量大、管道压力高、消防泵动作紧密,对换流站稳压装置运行稳定有较高要求.分析造成稳压泵频繁动作的故障原因,采取更换稳压罐胶囊、分段隔离法确定地埋管道渗漏等处置措施,有效保障消防水系统稳定可靠运行.
Abstract
Elaborate the introduction of the fire water system of a converter station in Pakistan,it is known that the buried fire pipe,the rain valve water spray flow,high pipeline pressure,the fire pump action closely,and the stable operation of the voltage regulator of the converter station has a high requirement.Understand the working principle of the fire stabilizing pump and the influence caused by the frequent action of the pressure stabilizing pump,analyze the failure causes of the frequent action of the pressure stabilizing pump.By analyzing and handling the capsule damage of the pressure stabilizing tank,and using segmented isolation methods to determine the underground pipeline leakage and other disposal measures,and effectively ensure the stable and reliable operation of the fire water system.
