针对给粉机在运行过程中频繁掉闸的问题,通过对掉闸现象的记录、统计、分析,找出其掉闸的根本原因是煤质差,直接原因是变频器加速时间设置偏短;采用加强配煤管理和延长变频器加速时间的方法,提高了变频器的适应性,基本解决了给粉机频繁掉闸问题.
針對給粉機在運行過程中頻繁掉閘的問題,通過對掉閘現象的記錄、統計、分析,找齣其掉閘的根本原因是煤質差,直接原因是變頻器加速時間設置偏短;採用加彊配煤管理和延長變頻器加速時間的方法,提高瞭變頻器的適應性,基本解決瞭給粉機頻繁掉閘問題.

@@@@For the pulverized coal feeder trip continually in running, the underlying cause and the immediate cause of pulverized coal feeder trip is respectively coal characteristic bad and shorter setting of the frequency converter’s acceleration time by record and statistic and analysis. The problem of pulverized coal feeder trip continual y is substantial y solved by strengthening coal blending management and prolonging the frequency converter’s acceleration time.
