Vibration Analysis of Pumps Units Based on Fuzzy Matter-element

摘要

This paper analysises and evaluates vibration situation and gives the general procedure for vibration analysis of pumps units,which contain determination of each evaluation matter-element and comprehensive evaluation method based on matter-element.Evaluation matter-element is established by evaluation system of pumps vibration,aimed at a particular example.The factors affecting the vibration of the pump unit has three major factors of the mechanical,hydraulic,electrical,sub-factors of the three factors.According to the characteristics of the pump unit vibration and the current technical condition,the vibration is divided into five levels:most serious,more serious,normal,minor,and slight.The evaluation weight matter-element are established by using AHP,weight are determined by using the combination of AHP and entropy,finally comprehensive evaluation of pumps vibration performance is practiced.Thus,this evaluation is feasible and useful.
