中文摘要 | 泵浦振動檢測的目的有三:(1)由振動的檢測作為產品改善的參考(2)作為泵浦交貨時的驗收依據(3)由振動檢測的結果作為預 知保養的準則,本文首先針對量測設備及使用範圍加以介紹,並對時域及頻域的轉換,以及固定頻寬和固定百分比頻寬加以說明,並列出振動 劣度判斷,以及馬達、葉片不平衡,軸不對心、共振,軸承故障,水力造成的振動,空蝕,回流,擾流等振動現象加以說明。 |
英文摘要 | There are three main purposes for pump's vibration test. (一) use the vibration test result as the guide for product improvement. (二) in the purchase project use the test result as the criterion whether to accept or reject the pumps. (三) use for the predictive maintenance program. The article presents first the brief description of the principle and application of the test equipment, then the differences between time domain and frequency domain signal, the constant bandwidth from the constant percent bandwidth. Finally the vibration Severity, and the vibration phenomenon of motor, blade unbalance, misalignment, resonance, bearing defect, hydraulic force, cavitation, recirculation, turbulence. are included. |
