摘要
为了对自吸泵在不同情况下的性能状态进行精准检测评估,更好地权衡自吸泵工作性能参数对水泵系统整体性能状态的影响。以一台80-70Z型号自吸水泵为研究对象,提出了一种新的Sugeno-模糊拟和算子及模糊积分,并将其应用于模糊概率运算的新方法。首先利用该方法得出单体水泵性能状态的模糊概率值;其次运用模糊综合评价法对各水泵的性能状态所属评价集进行有效评估;最后将所得的模糊概率值与综合评判结果进行比对,实验结果十分一致。从而验证了该方法的可靠性,并克服了模糊综合评判法在实际应用中的局限性和模糊性。
In order to accurately evaluate the performance state of the self-priming pump under different conditions,and better balance the influence of self-priming pump performance parameters on the performance status of the overall pump system,this article takes a 80-70Z model self-priming pump as the research object and a new Sugeno fuzzy quasi-sum operator and fuzzy integral are proposed and applied to the new method of fuzzy probability operation.Firstly,the fuzzy probability value of the performance state of the single water pump is obtained by using this method.Then,the fuzzy comprehensive evaluation method is used to effectively evaluate the evaluation set of the performance status of each pump.Finally,the obtained fuzzy probability values are compared with the comprehensive evaluation results,and the experimental results are very consistent,thereby verifying the reliability of the method,and overcomes the limitations and ambiguities of the fuzzy comprehensive evaluation method in practical applications.
