摘要
简单介绍了上海石化某装置的一台离心式风机在运行中出现异常噪声和振动大的故障情况,经过现场的测振,通过轴承故障频率公式计算和分析后,确定故障部位为轴承外圈滚道。经过检修后风机运行平稳,轴承特征故障频率大幅下降。
This paper briefly introduces the vibration fault and abnormal noise problem of a centrifugal blower in a plant of SINOPEC Shanghai. Through measuring the vibration on site and analyzing formula of the bearing's frequency of failure,it is determined that the fault is in the outer ring raceway of the bearing.After maintenance, the centrifugal blower can run smoothly and the frequency of failure of the bearing has dramatically dropped.
