生产中振动筛常见的4大故障以及处理方案
添加时间:2019-11-19

在生产实践中,掌握振动筛常见故障的诊断和处理方法,有利于及时发现设备隐患,从而进行有效维修处理;良好的设备维护保养也是保证设备处于良好技术状态,安全高效运行的保证。

振动筛的常见故障分析与处理

1.原矿筛分时达不到设计处理量

(1)如果是圆振动筛,最简单也是最常见的原因是筛子的倾角不够。实际应用中以20度倾角时最好,一般圆振动筛的倾角选取范围为16~20度。若倾角低于16度,就会发生筛上物走料不畅或物料向上滚动的现象。

2.轴承过热

由于轴承工作在重载,大离心力的工况下,所以发热较大。常由于选用了错误的轴承型号,缺少润滑和散热,轴承工作空间被污染等原因发生损坏主要的故障原因和维修方法如下:

4.声音异常现象或者噪声较大

如果振动筛在运行中产生声音异常现象,可能有3个原因:①轴承磨损;②筛网未压紧;③弹簧损坏。为此分别需要更换轴承,紧固各部位螺栓更换弹簧。一般在生产过程中,振动筛产生的噪声是不可避免的,但噪声太大对工作人员的身体会产生不利影响,为此可以采取以下措施降低噪声:

(1)筛箱侧板加约束阻尼层
