Abstract:

This paper introduces the vibration problem of high-pressure centrifugal water injection pumps in a residue hydrogenation unit and the treatment process, and compares two types of centrifugal water injection pumps from many aspects. Finite element analysis software is used for simulation analysis particularly in terms of wet rotor dynamics and hydraulics, and a corresponding improvement plan is put forward according to the analysis results, fundamentally solving the vibration problem of water injection pumps during actual operation and improving the reliability of high pressure centrifugal pumps during long period operation.
