摘要
本文简单介绍了几种不同结构型式的用于600MW以上超临界火力发电机组锅炉给水泵,从动平衡特性、轴向力平衡系统特性、产生的轴向力、汽蚀性能、抵抗热变形能力、芯包安装更换等几个方面进行了详细的比较说明。通过对比分析,为用户的实际需求及锅炉给水泵的国产化提供参考。
This paper briefly introduces several different types of feed water pumps used in supercritical thermal power units above 600 MW. Detailed comparisons are made in the aspects of dynamic balance characteristics, axial force balance system characteristics, generated axial force, cavitation performance, thermal deformation resistance and core package installation and replacement. Through comparative analysis, it can provide reference for the actual needs of users and the localization of boiler feed pump.
