泵振动噪声大故障原因
故障原因：1)传动装置找正不良2)转子平衡不良3)底座没有填实或地脚螺栓松动4)基础不坚固5)轴弯曲6)轴承磨损7)泵流量太大，超出使用范围8)管路支承不稳9)泵吸入空气10)轴承缺油或油质不良
故障显示的现象：1)轴承处振动较明显，可用直尺和塞尺检查传动装置2)轴承处振动较大，并且横向振动大于上下振动3)底座振动很大，甚至周围地面也有振动4) 一般发生在大泵中，底座和周围地面有明显振动5)轴承处振动较明显，伴有电流增大，轴承发热的可能6)轴承处的噪声较大，并可能发热。对滚动轴承检查游院较大，审动量较大，对滑动轴承，轴有下沉现象7)出口压力低，电流大，进出管路尤其是阀门处有较大的喇明流水声，伴有管路跳动8)管路有较大振动，噪声9)阵发性发生振动噪声，伴有出口压力不稳，流量时大时小10)轴承发热 渣浆泵厂家

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
