SDS-12.5隧道射流風機安裝方法

更新時間:2020-06-04 瀏覽次數(shù):6514

SDS-12.5隧道射流風機效率明顯優(yōu)于常規(guī)軸流風機,隧道射流風機產(chǎn)品其各項性能指標及耐腐蝕性、耐高溫性、可靠性等技術(shù)要求*適應各類地鐵、隧道的使用,優(yōu)化系統(tǒng)工程配套設(shè)備產(chǎn)品。

隧道射流風機外殼由進口機床旋壓翻邊成形,既保證機殼的同軸度和強度,又保證葉片徑向間隙,表面噴塑處理,外形美觀且防腐性能優(yōu)良。

風機葉片、輪轂由高壓鑄造機鋁合金模壓成形,產(chǎn)品強度高、一致性好,保證良好的風機運轉(zhuǎn)平穩(wěn)性。風機配套全封閉鼠籠式電機,絕緣等級H級,防腐等級IP55,適應各種隧道環(huán)境的使用要求。

隧道射流風機分帶消聲器和不帶消聲器[進出口加集(散)流器]二種規(guī)格,又分單向射流風機(SDS)和可逆式(雙向)射流風機[SDS(R)]二種通風形式??赡媸缴淞黠L機在緊急狀態(tài)下的正反轉(zhuǎn)切換時間極為重要,SDS(R)可逆式射流風機有電子式和機械式二種切換方法,可以在30秒鐘內(nèi)正反轉(zhuǎn)切換到風機額定轉(zhuǎn)速。

SDS隧道射流風機規(guī)格從Ф630mm~Ф1600mm,ZUI大推力3500N,風量大小可以通過改變?nèi)~片數(shù)和葉片角度來滿足要求,對任一負載和工況均可選擇到合適的風機。

隧道射流風機一般懸掛在隧道頂部或兩側(cè),不占用交通面積,不需另外修建風道,土建造價低;隧道射流風機安裝容易,運行、維護簡單,是一種很經(jīng)濟的通風方式。隧道射流風機在安裝時一般有以下幾點注意事項:

1、風機的基礎(chǔ)要求水平、堅固,且基礎(chǔ)高度≥200mm.

2、風機與風管采用風機軟連接(柔性材料且不燃燒)連接,長度不宜小于200mm、管徑與風機進出口尺寸相同。為保證風機軟連接在系統(tǒng)運轉(zhuǎn)過程中不出現(xiàn)扭曲變形,應安裝的松緊適度。對于裝在風機吸入端的帆布軟管,可安裝稍緊些,防止風機運轉(zhuǎn)時被吸入,減少帆布軟管的截面尺寸。

3、隧道風機的鋼支架必須固定在混凝土基礎(chǔ)上,風機其鋼支架與基礎(chǔ)之間必須增加橡膠減振墊。全部風機及電動機組件都安裝在整塊的鋼支架上,鋼地架安裝在基礎(chǔ)頂部的減振墊上,減振墊用多孔型橡膠板。

4、隧道風機出口的管徑只能變大、不能變小,后出風口要安裝防蟲網(wǎng),偏向上出風時須增加風雨帽。
