电动门维修归纳故障的大致部位或范围：根据故障的表现形式，推断造成故障的各种可能原因，并将故障可能发生部位逐渐缩小到一定的范围。其中尤其要善于运用"优选法"原理，分析整个电路包含几个单元电路，进而分析故障可能出在哪一个或哪几定网站建设  伺服液位仪  防撞墙模具 唐山护栏  钢纤维 天津除甲醛  保定铝型材个单元电路。总之，对各单元电路在整个电路系统中所担负的特有功能了解得越透彻，就越能减少检修中的盲目性，从而极大提高检修的工作效率。
The maintenance of the electric door summarizes the general parts or scope of the fault: according to the manifestation of the fault, infer various possible causes of the fault, and gradually reduce the possible parts of the fault to a certain range. In particular, we should be good at using the principle of "optimization method" to analyze the whole circuit including several unit circuits, and then analyze which one or several unit circuits the fault may occur. In a word, the more thorough understanding of the unique functions of each unit circuit in the whole circuit system, the less blindness in maintenance, and thus greatly improve the efficiency of maintenan
