2W. W-type twin screw pump


 

2W. Structural features of W-type twin screw pump:




2W. W-type twin-screw pump adopts double suction structure. Both ends of the screw are in the same pressure chamber, and the axial force can be balanced by itself. The bearings at both ends are externally mounted and lubricated with lubricating oil (grease) separately, so they are not affected by the transmission medium. The two screws are driven by a pair of synchronous gears. There is no contact between the screw tooth surfaces, but a small gap is left. The impurities in the medium can not directly wear the screw tooth surface (except scouring).




Except for some small displacement pumps (below 2W. W4.0), the pump body is generally equipped with internal flow safety valve, which has a certain protective effect when the discharge pressure exceeds the rated value.




There are two inlet and outlet directions on the pump body: one is horizontal inlet and horizontal outlet; 2. Horizontal entry and vertical upward exit; Users can choose according to their own needs.

2W.W型雙螺桿泵性能范圍:

1、最高工作壓力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

<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,請與制造廠聯系。

2W.W型雙螺桿泵具有以下優點:

1、有很強的自吸性能,多相混輸時,含氣率不高于80%,含沙量不高于500g/m3。

2、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。

3、輸送液體平穩、無脈動、無攪拌、振動小、噪音低。

4、雙吸式結構,轉子上沒有軸向力。

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、外置軸承結構,采用獨立潤滑,可以輸送各種非潤滑性介質。

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。
