萬州高品質防火閥價格

風機廣泛地應用于各個工業部門，一般講，離心式風機適用于小流量、高壓力的場所，而軸流式風機則常用于大流量、低壓力的情況，防火閥價格應根據不同的情況選有不同的風機分類。1鍋爐用風機,鍋爐用風機根據鍋爐的規格可選用離心式或軸流式。又按防火閥它的(de)作用(yong)分(fen)為鍋爐(lu)(lu)風(feng)(feng)機—向鍋爐(lu)(lu)內(nei)輸送空氣(qi)(qi)；鍋爐(lu)(lu)引風(feng)(feng)機把鍋爐(lu)(lu)內(nei)的(de)煙氣(qi)(qi)抽走。2通(tong)風(feng)(feng)換氣(qi)(qi)用(yong)風(feng)(feng)機,這類風(feng)(feng)機一般是供工廠及(ji)各種建筑物通(tong)風(feng)(feng)換氣(qi)(qi)及(ji)采暖通(tong)風(feng)(feng)用(yong)，要求(qiu)壓力不高，但噪聲要求(qiu)要低(di)，可采用(yong)離心式(shi)或軸流(liu)式(shi)風(feng)(feng)機。
