EK-1100-ZLD型汽轮机是我国从美国引进的七套化肥装置的动力源。该机转子的叶片及拉金损坏事故,在该化肥装置机械事故中所占比例最大,造成损失最多,占42.5％。因此认真分析该机拉金及叶片损坏原因,找出预防措施,对于确保化肥厂长期安全运行有重大的现实意义。从多次叶片损坏事故看,断裂叶片均处 EK-1100-ZLD-type steam turbine is introduced from the United States seven sets of fertilizer plant power source. The blades of the rotor of the machine and the failure of pulling the gold caused the largest proportion of mechanical accidents in the chemical fertilizer plant, resulting in the largest loss, accounting for 42.5% of the total. Therefore, a careful analysis of the reasons for the damage of the machine and the damage of the leaves and the identification of precautionary measures are of great practical significance for ensuring the long-term safe operation of the fertilizer plant. From many blade damage accident, the rupture blades are everywhere
