基于灰色关联分析法的溶液泵振动分析
|
摘要
为探究某LNG工厂脱碳MDEA溶液泵振动联锁停机影响要因,对事件发生规律进行梳理,全面分析运行工况,指导下步整改。基于某次振动联锁实例,采用灰色关联分析法,丰富数据量,选取事件发生前后全过程运行数据进行分析。研究得出,温度、振动、仪表损坏等诱发机泵联锁的原因具有交叉性,既能单一触发联锁又能互相促进导致停泵。运用灰色关联分析法进行数学建模,能充分利用当前数据,根据不同工况灵活设定母因子与子因子,有效将模糊定性的联锁停机现象进行全数据式动态分析。量化问题诱发点,多快好省地指导现场故障排除,解决了因分析手段有限而导致的决策瓶颈,避免了盲目拆解泵体诱发的误工现象,在一定程度上降低了购买更换备件的经济风险,提升了技术管理水平。
In order to explore the main factors influencing the vibration interlock shutdown of a decarbonized lean fluid pump in a LNG plant,the occurrence law of the event has been sorted out by comprehensively analyzing the operating condition so as to guide the rectification in the next step. Based on an example of vibration interlock,the grey relational analysis method is adopted to enrich data volume and the whole process operation data before and after the event is selected for analysis. The results show that temperature,vibration,instrument damage and other causes of pump interlock are intersecting,which can not only trigger interlock but also promote each other to stop the pump. The grey relational analysis method is used for mathematical modeling to make full use of current data. According to different working conditions,the master factor and sub-factor are set flexibly,and the whole data dynamic analysis is carried out for the fuzzy qualitative interlock shutdown. Induction points have been quantified,and guidance for trouble-shooting at site has been conducted effectively to solve the bottle-neck effects due to limited analyzing methods and avoid blind pump dismantle. The economic risks of buying and replacing spare parts have been reduced and the technical management level has been improved to certain extent.
