富溶剂泵管线的应力分析

Stress Analysis of Hydrogenation Feeding Pump Pipeline

泵的配管设计具有特定要求,泵的进出口管嘴的受力和力矩要符合API610相关规定。因此泵管道的配管设计尤为重要。利用CAESARⅡ对汽油加氢装置中的富溶剂泵进出口管线进行一次二次应力分析、管嘴受力分析、管道系统固有频率分析,可得出结论:通过改变管道系统的走向,适当的设置限位或者固定支架,可以在保证管道系统柔性的前提下,减小管道系统位移对泵管嘴受力的影响,提高泵进出口管道系统的固有频率,防止产生共振,从而设计出合理的泵进出口管道设计方案。

Piping design in hydrogenation unit is unique.The stress and moment of force of nozzle of the pump needs to comply with API610.So,Piping design of rich solvent pump is very important.CAESARⅡwas used to analyze primary stress,secondary stress,nozzle stress,natural frequencies of rich solvent pump in hydrogenation process,the following conclusions were drawn,changing the direction of pipeline and setting limit or fixing support could increase flexibility of pipeline,increase natural frequencies of pipeline,reduce the force of nozzle of pump.
