       离心风机出现了动平衡不良的故障问题,是不是叶轮引起的?今天我们就这个问题展开说说,其实,造成离心风机动平衡不良的因素有很多,不能从单方面考虑,具体内容如下:

一、风机叶轮出现不平衡现象而造成的;风机在长期运行过程中,叶轮表面积聚大量的粉尘或异物、叶轮在运转期间出现了磨损或腐蚀情况、叶轮出现了松动现象及叶轮修补后没有做动平衡处理等;

二、风机轴承故障造成的;轴承出现了磨损或断裂、轴承箱的固定螺栓出现松动现象、轴承安装不到位(例如:联轴器未做对中处理)等;

三、风管系统或其他设备产生的震动,造成了离心风机动平衡不良的情况;

引起离心风机动平衡不良的因素有很多,所以我们不能只根据片面状态去判定,需要使用震动平衡仪去逐一排查,找到问题的根本所在,再进行处理解决。


The centrifugal fan has a problem of poor dynamic balance, is it caused by the impeller? Today we will talk about this problem. In fact, there are many factors that cause poor dynamic balance of centrifugal fans, which cannot be considered unilaterally. The specific contents are as follows:

1、 The fan impeller is unbalanced; During the long-term operation of the fan, a large amount of dust or foreign matter accumulates on the surface of the impeller, the impeller is worn or corroded during the operation, the impeller is loose, and the impeller is not balanced after repair;

2、 Caused by fan bearing failure; The bearing is worn or broken, the fixing bolts of the bearing box are loose, and the bearing is not installed properly (for example, the coupling is not aligned);

3、 Vibration generated by air duct system or other equipment causes poor dynamic balance of centrifugal fan;

There are many factors that cause poor dynamic balance of centrifugal fan, so we can't judge according to one-sided state only. We need to use a vibration balancer to check one by one, find the root of the problem, and then deal with it.
