Application for Fuzzy Mathematics Failure Diagnosis Technology about Chilly Water Set of Single Screw

Abstract

In this dissertation, first based on the characteristics of fuzzy mathematics, a common fault membership function value table about the Chilly Water Set of Screw is established through analysis of the reasons for failure. Then it adopts comprehensive fuzzy evaluation method to diagnosis fault of chiller and develops a dedicated procedure based on Fuzzy Mathematics. Finally, the paper gives an example of fuzzy diagnosis about the screw-chiller, which can be applied to find the reasons for failure fast.
