Preliminary exploration: Fault diagnosis of the circulating-water heat exchangers based on sound sensor and non-destructive testing technique

Abstract

A heat exchanger is a piece of equipment built for efficient heat transfer from one medium to another, which is very important to petrochemical enterprises. Since heat system often uses industrial circulating water as cooling water, the heat exchanger is prone to scale, clogging and leakage, resulting in sub-standard products and even serious economic… (More)
