摘　　要：介绍了某钢厂超高压燃气发电站调试时出现的给水再循环管路振动大、噪声大的现象。通过现场观察及分析计算,采取了将原设计安装的单孔多级节流孔板替换为多孔多级节流孔板的措施,并加固再循环管路支架,彻底解决上述问题。The phenomenon of excessive vibration and noise in the water feeding recirculating pipes during commissioning of an ultra-high pressure gas power generating station is introduced. Through on-site observation and analytical analysis, we adopted the measure of replace the original single-pattern multi-stage reducing orifice with multi-pattern multi-stage reducing orifice, which completely solved the above problem.
