电磁阀在线更换
摘要：上海90万吨烯烃工厂2005年5月投入商用运行，其控制阀附件-电磁阀使用的是VERSA低功耗直流电磁阀，2010年8月和10月连续发生两起事故，导致分离区域局部停车，严重影响生产和企业效益。通过多次讨论和分析，决定对这类电磁阀进行在线更换,从而达到消除隐患，确保生产的正常进行。电磁阀在线主要工作包括：方案讨论，风险评估，技术、材料、器具准备，在线更换，观察效果。通过近4个月的工作，,效果良好,电磁阀的风险得到有效的控制。

Abstract: Shanghai 900,000 tons of olefin plant in May 2005 commercial operation, the control valve accessories-electromagnetic valve is using VERSA low power consumption dc electromagnetic valve, in August 2010 and October continuously happen two accident, resulting in separate areas local parking, the serious influence production and enterprise benefit. After several times of discussion and analysis, decided to this kind of electromagnetic valve replacement online, so as to eliminate hidden dangers and ensure the normal production. Electromagnetic valve online main work include: the project discussion, risk assessment, technology, materials, appliances preparation, online replacement, observing effect. Through the nearly four months of work, now, has already been done. According to the current of the actual application, the effect is good, the risk of electromagnetic valve is effectively controlled.
