中文摘要 | 由中鋼自行研發的設備振動線上監視診斷系統,於鋼板工場兩年半的使用期間 內,多次偵測到設備異常狀況,使現場維修人員得以適時採取因應措施,化解了設備劣化、 導致損毀的危機,不但避免了相當可觀的意外停機損失,同時也延長了設備的使用壽命,其 所獲致的效益估計每年達 2000 萬元。本文介紹此系統於使用期間內,所偵測到之設備振動 變化歷程,並在諸多成功的診斷案例中,針對其中 6 項, 分析其振動訊號及頻譜特徵,以 說明線上監診系統的準確性,以及其對現場從事設備狀況預知保養的重要貢獻。 |
英文摘要 | An on-line vibration monitoring and diagnosis system for machinery was developed at China Steel Corporation on its own. During its two-and-a-half- year application period in the Plate Mill, this system has successfully detected many abnormal conditions of facilities. The maintenance personnel were thus able to take appropriate actions well in time to eliminate the facility deterioration and the hazard of machine failures. Great losses due to accidental breakdowns have been avoided consequently. The service life of facilities has also been prolonged. The achieved benefit was estimated to be around 615, 000.-US $annually. This article describes the vibration histories of the feed rolls of a rolling mill and analyzes the characteristics of the vibration signals and the frequency spectra for 6 real cases. These cases confirm the accuracy and reliability of this system and manifest its precious contribution to the practice of predictive maintenance in the field. |
