判斷輸送機 故障的竅門
Pulisher:admin  Time:2012/8/29 8:12:26  Click:4816
根據(jù)減速器的運轉(zhuǎn)聲音判斷其工作狀態(tài)用耳靠近輸送機的減速器聽或用一個改錐觸哉減速器外殼上,用耳貼靠在木把上聽減速器齒輪及軸承的運轉(zhuǎn)聲音,減速器正常的運轉(zhuǎn)聲音是比較平衡的,當聽到周期性異響,說明減速器齒輪的牙齒變形造成齒隙變小或齒間夾雜金屬異物;當在減速器軸承處聽到頻繁不規(guī)則的異響,說明軸承架損壞或珠粒損壞;當感覺到減速器遺常振動,說明齒輪整個嚙合不好或地腳螺栓松動。出現(xiàn)異常情況必須及時處理。

  檢查托輥組的運行狀況

  (1)在皮帶輸送機運轉(zhuǎn)時,觀察上、下托輥及緩沖托輥是否靈活

  (2)調(diào)心托輥、立輥和回轉(zhuǎn)部位,在輸送帶跑偏時,是否轉(zhuǎn)動靈活。

  (3)各托輥間及托輥與中間架間是否有卡阻物。

  (4)各托輥有無損壞、異響,是否缺油。

  (5)有無缺輥。

  (6)各托輥與輸送帶是否接觸良好。

  3、根據(jù)運轉(zhuǎn)電流判斷帶式輸送機的負荷情況

  在額定電流及額定電流以下帶式輸送機運轉(zhuǎn)時,證明帶式輸送機在額定負荷下運轉(zhuǎn),帶式輸送機工作正常;當電流超過額定值,說明帶式輸送機超載運行;當電流突然上升,大大超過額定電流,可能有卡阻物卡住輸送帶,因立即停機檢查。
