【摘要】 本课题基于Microsoft Access 2000建立“四管”爆漏案例数据库,包括电厂名称、锅炉号、锅炉型号、蒸发量、机组容量、累计运行时间、爆漏原因、爆漏部件、爆漏结果和技术分类等表单。数据库中收录了原华中电管局所属湖北、湖南、河南、江西四省共48个电厂1982～2002年间3179条锅炉“四管”爆漏事故案例。基于C/S模式开发电站锅炉“四管”爆漏管理系统,实现数据上报、查询、统计分析等功能;利用本系统各发电公司可及时了解掌握所辖电厂锅炉“四管”爆漏情况,各个电厂也可以利用本系统实现网络资源共享。利用该管理系统对原华中电管局所属电厂的锅炉“四管”爆漏事故案例按机组容量、爆漏部件、爆漏原因进行统计分析,归纳“四管”爆漏的主要原因,以及与运行工况、时间、部件的关系,找出“四管”爆漏的规律和主要失效原因,针对具体有代表性的电厂提出部件监督、检修及防护措施,以有效地减少“四管”爆漏次数,降低事故率,这对火力发电厂安全经济运行具有重要地现实意义。更多还原

【Abstract】 Designed the database and developped the system. based on the Microsoft Access 2000, we designed the power plant name、 boiler number、 boiler type、 evaporate rate 、 unit capacity、 total working time, failure reason, failure part, failure result and technique classify forms etc. We collected 3179 piece of Hubei, Hunan, Henna and Jiangxi province’ 48 power plants which belong to the central china electric power corporation from 1982~2002. We put them in order and input them. Based on the C/S model we developed the system. The system has the following functions: A client can hand over the new case by Internet, demanding and data statistics and analyzing. Using the system, the manager can kown the boiler "four tube" explosive leakage situation of the department well, the resources can be enjoyed together.we classify them for unit capacity, failure part and failure reason, analyze the main reason to "four tubes" failure, found the relation to work circumstance, total working time and failure part, bring forward the potential regular pattern and reason to reduce the possibility of "four tubes" failure repeatedly, to drop the failure frequency and get the unit efficiency increased.更多还原
