1982年9月水电部在我区呼市召开了全国汽轮机叶片安全讨论会,会议重点研究和交流了以1132型线的169毫米叶片断裂损坏原因以及改进的经验.与会者进一步明确了“169”叶片断裂主要是动强度不足.所采取的有效措施是用整圈松拉金结构以及降低蒸汽弯应力为主要目的的改型叶片等措施. In September 1982, the Ministry of Electricity and Hydroelectric Power held a steam turbine blade safety seminar in Hohhot, Hubei Province, focusing on the research and exchange of the cause of 169mm blade breakage damage and its improvement experience on 1132. The participants further clarified the “169” The blade rupture is mainly lack of dynamic strength, and the effective measures taken are the measures such as the modified blade whose main purpose is to reduce the steam bending stress by the whole circle of loose-pull gold structure.
