摘要
通过对华电吴江2×9E燃机项目中天然气间通风风机(88VL)系统在安装、调试中出现的、由于风机出力不足、出口风门打开后相应拐臂上升高度不够、外部行程开关动作不到位等引起的燃机跳闸问题进行详细分析,提出了改变风机外部行程开关安装方式、更改热工开关量控制接线等简单易行的技术改造方案,并在吴江1号燃机上成功实施。改造方案加快了电建安装速度、方便了设备调试、提高了燃机安全性,并得到燃机厂家技术人员的认可,且被燃机厂家应用于同类型燃机项目的安装调试。
Through the analysis on the gas turbine tripping caused by the insufficient output of the ventilation fan,the inadequate rising height of the crank arm of the fan outlet and the wrong position of the limited switch in the installation and debugging of the gas room ventilation fan （88VL） of Huadian Wujiang 2×9E Gas Turbine Project,certain simple and feasible innovative plans such as changing the installation mode of the fan external limit switch and the limit switch control wiring are proposed and implemented successfully on the Gas Turbine 1 of the project,which have speeded up the installation,made the equipment debugging more convenient and improved the security of the gas turbine.Therefore,these plans are accepted by the gas turbine manufacturer and applied in the installation and debugging of the gas turbines of the same type.
