哪些方式能夠正確的使用消防排煙風機

1、消防排煙風機選用基本參數為工作溫度,風量,電動機大功率,噪聲,電動機大功率,傳動比及勵磁電。2、消防排煙風機的風量應按所須的風標值提不小于百分之十到百分之二十的頗具量。3、在化學物質溫度不過85℃的規范下可以長久性一切正常運行。4、消防排煙風機應保證:當運送化學物質溫度在280℃時要不斷工作上30min,并在化學物質溫度致冷至操作溫度時仍能不斷一切正常運作。5、消火栓系統沖裝排煙風機的標準氣壓值應按消火栓系統較不太好環城路進行計算,并保證在消防救援窗內余發電電壓40~50Pa。前解決室、合用前室、消防電梯前室、避難層等內部的余發電電壓25~30Pa。6、消防排煙風機在使用說明書中得出的工作中情況點一下的比壓級噪聲限定值應符合的規定。7、消火栓系統的風機宜單獨設置。消防排煙風機的位置宜處于排風系統區的排污管道或層。
