雙螺桿泵
雙螺桿泵的優(yōu)點
1、輸送液體平穩(wěn)、無脈動、無攪拌、振動小、噪音低。
2、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.
3、外置軸承結(jié)構(gòu),采用獨立潤滑,可以輸送各種非潤滑性介質(zhì)。
4、采用同步齒輪驅(qū)動,二轉(zhuǎn)子之間不接觸,即使短時間空轉(zhuǎn)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(zhì)(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(zhì)。
7、雙吸式結(jié)構(gòu),轉(zhuǎn)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。
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(zhì)粘度 1~3000mm2/s,降低轉(zhuǎn)速可達到106mm2/s
介質(zhì)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(zhuǎn)速:

如需要選用其它材料時,請與制造廠協(xié)商。
選用泵應(yīng)考慮的主要事項
1、介質(zhì)的潤滑性,清潔度、腐蝕性。
2、介質(zhì)的粘度,溫度。
3、介質(zhì)進、出口壓力,安裝高度。
4、使用場合的防爆要求。
5、訂貨時請注明規(guī)格、型號、設(shè)計使用壓力、轉(zhuǎn)速、介質(zhì)粘度、溫度、電機防爆級別、介質(zhì)名稱。
如:2W.W5.0-64-J-1,1.0MPa,980r/min,
介質(zhì):粘度: 500cSt,80℃,EXd2BT4
介質(zhì):重質(zhì)燃料油。
希望選擇時留有一定的富裕量,以確何安全可靠。
