Online Vibration Condition Monitoring of Gas Circulation Fans in Hardening Process

摘要

Vibration analysis and the Shock Pulse Method (SPM) are two of the most popular condition monitoring techniques used in Condition-Based Maintenancern(CBM) policy, especially for rotating equipment. To illustrate the extent to which advanced CBM techniques (in this case, vibration analysis and SPM) arernapplicable and cost effective in a manufacturing company, a pilot project was followed in real time. The pilot project was performed at a largernmanufacturing site in Sweden. The purpose of the project was to implement online condition monitoring of five critical gas circulation fans in the hardeningrnprocess of the manufacturing company. This paper presents some of the main findings of the online condition monitoring of the fans for a period of threernyears. Consequently, based on the empirical data, the company was able to gain great profit due to preventing production losses by preventing breakdownsrnof the fans.
