1、風機的用途
G4- 68、Y4- 68型離心通引風機均系1982年風機行業聯合設計的系列產品,它適用于火力發電廠中230t/h以下蒸汽鍋爐的通、引風系統。在無其它特殊要求時,G4 - 68型亦可用以礦井通風及一般通風。兩型風機均具有高效率、低噪聲、高強度等優點。
通風機輸送的介質為空氣,溫度不得超過80℃。引風機輸送的介質為煙氣、溫度不得超過250C。
在引風機前,必須加裝除塵效率不低于85%的除塵裝置,降低進入風機的煙氣含塵量,以利于提高風機的使用壽命通風機與引風機均為單吸入進氣,有№8、9、10、 11.2. 12.5、14、16共七個機號。
2、風機的結構
略
3、風機的型式
每種風機均可制成右旋轉或左旋轉兩種型式,從電機一端正視風機, 葉輪按順時針方向旋轉的,稱為右旋風機,以“右"表示:葉輪按逆時針旋轉的,稱為左旋風機以“左”表示。
風機的出口位置以機殼的出風口角度表示,“左”、“右”均可制成0°、45°、90°、135°、180°、 225°共六種角度。
4、風機性能表
性能表中性能均指調節葉片為全開0°時。
風機性能條件為:
通風機按氣體溫度t =20℃氣體密度p=1.2 kg/m3 大氣壓力P= 101325 Pa。
引風機按氣體溫度t= 140℃氣體密度p=0.85 kg/m3 大氣壓力P=101225Pa。
