2W.W密封型雙螺桿泵

2W.W密封型雙螺桿泵的優點
   1、輸送液體平穩、無脈動、無攪拌、振動小、噪音低。
   2、有的自吸性能,多相混輸時,含氣率不高于80%,含沙量不高于500g/m3.
   3、外置軸承結構,采用獨立潤滑,可以輸送各種非潤滑性介質。
   4、采用同步齒輪驅動,二轉子之間不接觸,即使短時間空轉也無妨。
   5、泵體帶有加熱套,可以輸送各種清潔或含有固體小顆粒的低粘度或高粘度介質(一般顆粒直徑小于0.12-0.2mm)
   6、正確的選用材料,甚至可以輸送很多有腐蝕性的介質。
   7、雙吸式結構,轉子上沒有軸向力。
   8、軸端采用機械密封或波紋管機械密封,具有壽命長、泄漏少、適用范圍廣的特點。
 
2W.W密封型雙螺桿泵性能范圍
   1、   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,為泵能在較   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
  <400 1500
  400 ~1200  1000
  1200~3600  750
  對于粘度   高的介質,所應選用的轉速和驅動電機功率,請與制造廠聯系。
