中文摘要 | 本研究開發出一套軋延機進給輥狀況監視診斷系統。其原理係線上偵測進給輥之振動訊號,並將此訊號先利用前端控制器進行訊號處理及數位化,然後透過網路線,將其傳送至辦公室電腦。電腦即根據量測訊號之大小和頻率特徵以及儲存於其中之振動診斷法則,自動判斷並顯示進給輥之劣化狀況以及可能之異常原因。系統之功能包括顯示進給輥狀況、異常原因分析、顯示振動波形、頻譜以及包絡線頻譜和雜訊分析等。在研究過程中,經由長期量測進給輥的軸承振動,並比對設備狀況與振動訊號特徵之關係,找出了進給輥各種劣化狀況 (包括傳動齒磨耗、軸承座鬆動以及軸承磨耗等 ) 之振動特徵, 進而確立了進給輥狀況之振動診斷法則。在測試設備損壞拆解後,由觀察到的損壞及磨耗情形,驗證了此診斷法則的正確性。本系統上線使用後,成功地偵測到進給輥傳動軸螺栓鬆脫及軸承磨耗破損等異常狀況,避免了設備突然故障所可能造成的重大損失。此外,本系統對於延長進給輥之使用壽命,降低維護成本,亦提供了相當大的幫助。本文描述所開發出來的進給輥振動診斷法則,以及監視診斷系統之功能。 |
英文摘要 | A condition monitoring and diagnosis system that provides early warnings regarding machine malfunctions has been developed for feed rolls so as to avoid major losses resulting from unexpected shutdown. This system measures bearing vibration signals of feed rolls on-line and judges the feed roll conditions automatiocally according to the diagnosis rules stored in the computer. The feed roll conditions and a possible fault diagnosis along with the vibration wave forms, frequency spectra and envelop spectra, etc. are displayed on the computer screen. The diagnosis rules have been derived based on the results of long-term vibration measurements on two feed rolls of the plate mill at China Steel Corporation. These rules have been proved by many case studies to be very effective and reliable. This system offers valuable assistance for condition-based maintenance of feed rolls. It also helps in prolonging the machine service life, enhancing the product quality and reducing the cost as well. |
