由于冷凝器在汽轮机组冷(静)、热(动)状态下参数变化较大,使汽轮机后汽缸受到竖直方向(上或下)的外力并变形,造成机组联轴器对中的破坏,影响机组的安全运行。本文分析了冷凝器与汽轮机刚性、挠性二种联接方式对机组对中的影响,同时结合施工实例介绍现场处理方法。 Because of the large variation of the parameters of the condenser in the cold (static) and thermal (dynamic) conditions of the steam turbine, the rear cylinder of the steam turbine is subjected to the external force in the vertical direction (up or down) and deformed, resulting in the damage to the coupling of the turbine, Affect the safe operation of the unit. This paper analyzes the influence of the rigid and flexible coupling modes of condenser and steam turbine on the unit alignment, and introduces the on-site treatment method combined with construction examples.
