Grey Fuzzy Evaluation on Technical Condition of Canned Motor Pump

It is difficult to assess the technical condition of the canned motor pump because of its various factors and insufficient monitor information.Considering the main failure modes and phenomena determined by FMEA,the condition monitoring is carried out correspondingly.Based on the condition monitoring results,the technical condition is comprehensively assessed by the grey fuzzy evaluation.The method gives a new approach to assess the technical condition of complicated equipments.A numerical example is given to demonstrate the rationality and applicability of the proposed method.
