针对进口大型汽轮机蒸汽入口管道荷载过大造成机器报警停车的问题,通过对整个管系的热应力计算和支吊架设计的系统研究,详细分析了不合理的支吊架设计和安装对机组接口荷载的不利影响,通过优化设计使管系设计合理,运行安全可靠;并提出了正确进行高压蒸汽管线支吊架设计和安装的建议。 Aiming at the problem that the machine is shut down when the load of imported large-scale steam turbine steam inlet pipe is too large, through the systematic study on the thermal stress calculation and the hanger design of the whole pipe system, the unreasonable hanger design and installation are analyzed in detail. The adverse effect of load, the design of the piping system is reasonable and the operation is safe and reliable through the optimized design; and the suggestion of correctly designing and installing the high-pressure steam pipeline hanger is put forward.
