摘要：
The vibration response of the reciprocating bilge pump was analyzed using traditional vibration monitoring methods. The analysis indicates vibration response of some measuring points increased, while some decreased. The analysis reveals the difficulty of distinguishing the location of fault, due to changes of the vibration response. This paper proposes to analyze fault in depth by adopting a load identification method. It is easy to distinguish the normal state and fault state in respect of the characteristics of the excitation source by stripping the influence of transmission path. The results demonstrate accurately that the meshing wear of worm gear resulted in bilge pump fault and this approach can be used as future reference for fault diagnosis of other mechanical equipment.
