電動車庫門由於安裝質量或受使用環境的影響,在運行過程中難免會發生問題而需要調整,在日常使用中經常存在這樣一種情況:小故障不處理變大故障,大故障不處理變成大維修工程,其費用也隨之而來由小費用變彌補的大費用再變成難以解決的大費用,從而導致整個車庫門的癱瘓。
捲閘王在這裡整理了通常的電動車庫門故障及維修方法。
維修電動車庫門首先要對車庫門結構有一定了解,其實很簡單,電動車庫門由門板,車庫門電機以及車庫門配件組成,電動翻板車庫門的運行方式是往上滑升的,結構稍微複雜點,以下捲閘王就來為大家介紹一下電動車庫門門體故障的維修方法:
故障一:門體單向運行
排查原因:
·行程開關損壞或行程開關線短路
·光電開關光路上有障礙物
·啟閉負載力調節沒有到位
維修方式:
·檢查行程開關及行程開關接線
·清除光電形狀光路上的障礙物
·重新調節啟閉負載力
故障二:門體衝過行程開關
排查原因:
·行程開關損壞或行程開關線斷路
維修方式:
·檢查行程開關及行程開關接線
故障三:門體運行噪音過大
排查原因:
·五金件安裝不牢固
·驅動裝置拉桿沒有位於門體中心線上
·門體運行導軌不平行
·合頁,滾輪處沒有取代潤滑油
維修方式:
·堅固五金件
·調節驅動裝置拉桿與門體中心線重合
·調節門體運行導軌相互平行
·在合頁,滾輪處覆潤滑油
故障四:驅動裝置正常運行,但門體不運行
排查原因:
·滑架上的離合器沒有復位
·啟閉負載力調節沒有到位
維修方式:
·復位離合器
·重新調節啟閉負載力
