In order to accurately evaluate theperformance state of the selfpriming pump under different conditions

andbetter balance the influence of selfpriming pump performance parameters on theperformance status of the overall pump system

this article takes a 8070Z modelselfpriming pump as the research object and a new Sugeno fuzzy quasisumoperator and fuzzy integral are proposed and applied to the new method of fuzzyprobability operation Firstly

the fuzzyprobability value of the performance state of the single water pump is obtainedby using this method. Then

the fuzzy comprehensive evaluation method is usedto effectively evaluate the evaluation set of the performance status of eachpump. Finally

the obtained fuzzy probability values are compared with thecomprehensive evaluation results

and the experimental results are veryconsistent

thereby verifying the reliability of the method

and overcomes thelimitations and ambiguities of the fuzzy comprehensive evaluation method inpractical applications
