摘　　要：某厂300 MW直接空冷机组抽真空系统运行中出现了许多影响系统设备的安全性和稳定性的问题。对抽真空设备和系统进行技术改造,增加一台套射汽抽气器+小水环真空泵的抽真空系统,并对空冷抽真空管路进行适当加粗改造。改造后显著提升了系统稳定性和经济效益,为同类型机组抽真空系统改造提供了借鉴。There are many problems affecting the safety and stability of the vacuum pumping system of 300 MW direct air cooling unit in a certain plant.The vacuum pumping equipment and system are reformed,a vacuum pumping system with a small water ring vacuum pump of the exhaust gas extractor is added,and the air-cooled vacuum tube road is by appropriate thickening.The system stability and economic benefit are improved significantly,which provides a reference for the transformation of vacuum pumping system of the same type of units.
