B4-68防爆離心風機風量從600-240000立方米/小時,風壓250-3800帕斯卡,功率:0.55-220kw,低壓大風量,有普通型、防腐型、防爆型、高溫型4種規格。電機直聯、皮帶傳動等方式
.用途
B4-68型離心通風機一般用于工廠及大型建筑物的通風換氣,既可用作輸入氣體,亦可用作輸出氣體,本風機可輸送空氣或其它不自燃、不易爆、不揮發、對人體無害、對鋼材無腐蝕性之氣體,且氣體內不得有粘性物質,所含塵土及硬質顆粒物不大于150mg/m3,氣體溫度不得超80℃。
結構特征
B4-68型風機的№2.8~6A主要由葉輪、機殼、進風口等部分配電機直聯組成?!?.3~20除上述部分外還有傳動部分:
葉輪:由12片后傾機翼形葉片焊接于弧錐型的輪蓋與平板輪盤中間,均用鋼板制造,并經靜動平衡校正和超速運轉實驗,空氣性能良好,效率高,運轉平穩。
