● 結構形式
一般采用機械密封。泵通過爪型聯軸器由電動機驅動。從主軸外伸端向泵年,為順時針旋轉。
● 材 質
主、從螺桿16MnCrS5,40Cr,45,38CrMoALA
泵體:HT200,QT450-10,ZCuSn10Pl,ZG270-500
● 雙螺桿泵性能范圍
1、zui高工作壓力4.0MPa
2、流量范圍 1~1000m3/h
3、溫度范圍-20~120℃
4、介質粘度 1~3000mm2/s,降低轉速可達到106mm2/s
介質粘度對雙螺桿泵性能影響較大,泵的名義排量是指在特定粘度條件下的排量,為保證泵能在較高效率下工作,在試驗不充分時,建議按下列粘度條件選擇轉速:
介質粘度cSt 轉速r/min 2Ga.2Gb.2Ga91-35雙螺桿泵
<400 1500
400 ~1200 1000
1200~3600 750
對于粘度更高的介質,所應選用的轉速和驅動電機功率,請與制造廠.
