摘　　要：在诱发机组振动的潜在因素中 ,与汽轮机相连接的蒸汽及油系统管道由于运行中高温热变形引起的对本体的推力是其中的重要方面。该文提出了研究管道推力对电站汽轮机安全运行影响的综合试验研究方法 ,并在现场机组故障诊断中得到了应用。图 2参Thrust forces, generated by thermal distortion of steam and oil pipings joined to steam turbines, during operation, and acting on the turbine proper, constitute important potential factors for inciting vibration of a set. The paper suggests a comprehensive test study method for exploring the influence of piping thrust forces on the operational safety steam turbines, which has been used in various on site failure diagnosis.
