The strong vibration of reciprocating pump in oil transportation station pipeline system will seriously affect the safe running of the equipment and pipeline. And the resonance between pipe and equipment will cause more severe damage. Therefore before the formal operation of station, not only static stress analysis, but also modal analysis and vibration analysis are necessary for the reciprocating pump pipeline system. The analysis method using CAESAR II software pipeline system for numerical simulation of the reciprocating pump XX pump station can provide reference for designers and can be used to determine the type and location of pipeline constraints and consequently reduce vibration damage.
