封严环的不平衡量及配合关系对低压系统振动的影响分析
|
摘要
为研究低压系统振动的影响因素,通过结构平面简化和数据统计,分析盘间封严环不平衡量、盘间封严环与低压一级涡轮盘配合间隙值等因素对低压系统振动的影响,提出盘间封严环的不平衡量越大则低压系统振动的可能性越大、盘间封严环与低压一级涡轮盘配合间隙值越大则低压系统振动的可能性越大。因此,控制盘间封严环不平衡量和盘间封严环与低压一级涡轮盘的配合间隙值是控制低压系统振动的有效措施。
In order to study factors affecting the vibration of low pressure system, through structural plane simplification and statistical analysis, the influence of the unbalance between the disc seal ring, the gap between the disc seal ring and the low pressure turbine disk on the vibration of the low pressure system was analyzed. It is proposed that the greater imbalance of disc seal ring, the greater possibility of the vibration of the low pressure system, and the greater clearance between the seal ring and the low pressure first turbine disk, the greater the possibility of the vibration of the low pressure system. Therefore, it is an effective measure to control the vibration of the low pressure system by controlling the unbalance between the disc seal ring and the gap between the disc seal ring and the low-pressure first level turbine disk.
