摘　　要：针对600 MW机组凝汽器复合真空泵抽气系统建立数学模型,进行了喷水冷却优化,并分析了喷水冷却器减温水质量流量对泵组功耗的影响。结果表明:采用喷水冷却器冷却时应尽量降低混合气体温度并且避免蒸汽发生冷凝,可降低泵组功耗。To optimize the water-jet cooling effectiveness in an extraction system for the composite vacuum pump of a 600 MW unit condenser,a mathematical model was established for the extraction system,while an analysis was conducted on the effects of water-jet flow on the power consumption of the pump set.When the water-jet cooler is applied,the temperature of mixed gas should be cooled down as much as possible to prevent the steam from condensation,thus reducing the power consumption of the pump set.
