制氢吸附器全尺寸疲劳试验系统开发

Development of Full-Scale Fatigue Test System for Hydrogen Absorber

针对一台服役期满的石化制氢装置吸附器,根据技术参数和试验现场条件,采用容积填充法减少吸附器有效容积约60%,通过理论计算,得到了吸附器疲劳试验容积增量约为81L,开发了全尺寸疲劳试验系统。调试和应变测试结果表明,吸附器在试验条件下的疲劳周期和受力状况与服役工况基本一致。

For a petrochemical hydrogen production unit adsorber which has completed its service,according to the technical parameters and the conditions of the test site,volume filling method was used to reduce about 60% of the effective volume of the absorber,the volume increment of fatigue test which is about 81 L was calculated by theoretical formula,and the full-scale fatigue test system was developed.The results of adjustment and strain test show that the fatigue period and stress state of the absorber under the test conditions are basically the same as the service conditions.
