摘要
某型300MW机组汽轮机的旁路系统在运行时,旁路阀的阀瓣突然发生了断裂。通过反复试验和综合失效原因进行了分析,查明了阀瓣断裂的原因。为此,改进了阀瓣的加工工艺,并对阀瓣制造控制程序进行了优化。
When a 300 MW turbine bypass system was running, a clack of the bypass several tests and failure analysis, we found out the cause of the fracture. So we improve the program that controls clacks manufacturing. valve was fractured. After the process of the clack and
