   防爆軸流風機的主要故障及原因
  1、防爆軸流風機振動劇烈
 ?、亠L機軸與電機軸不平行、皮帶輪錯位
 ?、跈C殼或進風口與葉輪摩擦
 ?、刍A的鉚釘松動或葉輪變形
 ?、苋~輪鉚釘松動或葉輪變形
 ?、萑~輪軸盤孔與軸配合松動
 ?、奕~片有積灰、污垢、磨蝕或軸彎曲使轉子失衡
 ?、唢L機進、出口管道安裝不良、產生共振
 ?、鄼C殼與支架、軸承座與支架、軸承座與軸承蓋等聯接螺栓松動
  2、軸承溫升過高
 ?、佥S承座振動劇烈
 ?、跐櫥瑒┱扯炔粚ψ冑|或含有異物,潤滑劑填充不足或過多
 ?、蹪L動軸承損壞或軸承彎曲,軸承內環或外環配合公差過松或過緊
  3、電機電流過大或溫升過高
 ?、匍_車時進風口管道未關嚴
 ?、诒凰蜌怏w中含有粘性物質
 ?、壑鬏S轉速超過額定值
 ?、茌S承箱振動劇烈
 ?、蓦姍C輸入電壓過低或電流缺項
  4、防爆軸流風機皮帶跳動或滑下:
  皮帶磨損、拉長時期過松或兩皮帶輪槽彼此不在同一中心線上。
