泵振動噪聲大故障原因
故障原因：1)傳動裝置找正不良2)轉(zhuǎn)子平衡不良3)底座沒有填實(shí)或地腳螺栓松動4)基礎(chǔ)不堅(jiān)固5)軸彎曲6)軸承磨損7)泵流量太大，超出使用范圍8)管路支承不穩(wěn)9)泵吸入空氣10)軸承缺油或油質(zhì)不良
故障顯示的現(xiàn)象：1)軸承處振動較明顯，可用直尺和塞尺檢查傳動裝置2)軸承處振動較大，并且橫向振動大于上下振動3)底座振動很大，甚至周圍地面也有振動4) 一般發(fā)生在大泵中，底座和周圍地面有明顯振動5)軸承處振動較明顯，伴有電流增大，軸承發(fā)熱的可能6)軸承處的噪聲較大，并可能發(fā)熱。對滾動軸承檢查游院較大，審動量較大，對滑動軸承，軸有下沉現(xiàn)象7)出口壓力低，電流大，進(jìn)出管路尤其是閥門處有較大的喇明流水聲，伴有管路跳動8)管路有較大振動，噪聲9)陣發(fā)性發(fā)生振動噪聲，伴有出口壓力不穩(wěn)，流量時(shí)大時(shí)小10)軸承發(fā)熱 渣漿泵廠家
Causes of pump vibration and noise
Fault cause: 1) poor alignment of transmission device; 2) poor balance of rotor; 3) no filling of base or loosening of anchor bolt; 4) weak foundation; 5) bending of shaft; 6) wear of bearing; 7) too large pump flow, out of service range; 8) unstable pipeline support; 9) air intake of pump; 10) lack of oil or poor oil quality of bearing
Fault display: 1) the vibration at the bearing is obvious. Use a ruler and feeler gauge to check the transmission device. 2) the vibration at the bearing is large, and the lateral vibration is larger than the vibration at the upper and lower parts. 3) the vibration at the base is large, even the vibration at the surrounding ground. 4) generally, the vibration at the base and the surrounding ground is obvious. 5) the vibration at the bearing is obvious, accompanied by the increase of current and the possibility of bearing heating. 6) the shaft The bearing is noisy and may be hot. For the rolling bearing, the inspection shows that the traveling block is large and the review momentum is large. For the sliding bearing, the shaft has sinking phenomenon. 7) the outlet pressure is low and the current is large, and there is a large sound of Lamang running water in and out of the pipeline, especially at the valve, accompanied by the pipeline runout. 8) the pipeline has a large vibration and noise. 9) the vibration noise occurs intermittently, accompanied by the outlet pressure is unstable, and the flow is large and small. 10) the bearing hot slag pump manufacturer
