生產中振動篩常見的4大故障以及處理方案
添加時間:2019-11-19

在生產實踐中,掌握振動篩常見故障的診斷和處理方法,有利于及時發現設備隱患,從而進行有效維修處理五百万彩票网;良好的設備維護保養也是保證設備處于良好技術狀態,安全高效運行的保證。

振動篩的常見故障分析與處理

1.原礦篩分時達不到設計處理量

(1)如果是圓振動篩,最簡單也是最常見的原因是篩子的傾角不夠。實際應用中以20度傾角時最好,一般圓振動篩的傾角選取范圍為16~20度。若傾角低于16度,就會發生篩上物走料不暢或物料向上滾動的現象。

2.軸承過熱

由于軸承工作在重載,大離心力的工況下,所以發熱較大。常由于選用了錯誤的軸承型號,缺少潤滑和散熱,軸承工作空間被污染等原因發生損壞主要的故障原因和維修方法如下:

4.聲音異常現象或者噪聲較大

如果振動篩五百万彩票网在運行中產生聲音異常現象,可能有3個原因:①軸承磨損;②篩網未壓緊;③彈簧損壞。為此分別需要更換軸承,緊固各部位螺栓更換彈簧。一般在生產過程中,振動篩產生的噪聲是不可避免的,但噪聲太大對工作人員的身體會產生不利影響,為此可以采取以下措施降低噪聲:

(1)篩箱側板加約束阻尼層
