Aiming at the diaphragm bolthole crack in LP casing of turbine under normal operating conditions in some power plant,modeling-based computational analysis is made of the bolthole.
针对某电厂汽轮机低压缸隔板螺栓孔在正常运行工况下开裂的问题,对该隔板螺栓孔进行了建模计算分析,通过应力计算,指出隔板螺栓孔开裂的主要原因为设计和选材不合理,导致运行过程中因受动静碰摩等引起的振动异常所带来的持续的交变应力变化而使隔板在应力集中处产生裂纹。
补充资料：肠系膜裂孔疝
肠系膜裂孔疝
mesenteric hernia
小肠穿过肠系膜孔而形成的疝，属腹内疝。严格讲其不能称为疝，因不具有疝囊。可为先天性，也可为创伤后或手术后遗留，小肠穿过系膜孔后容易发生狭窄或扭转，临床症状为急性机械性肠梗阻的表现。与粘连带所致的梗阻相似。诊断只能在手术时证实。治疗为手术复位并闭合肠系膜孔。
