2W.W密封型雙螺桿泵的優(yōu)點(diǎn)
1、輸送液體平穩(wěn)、無(wú)脈動(dòng)、無(wú)攪拌、振動(dòng)小、噪音低。
2、有很強(qiáng)的自吸性能，多相混輸時(shí)，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(dú)立潤(rùn)滑，可以輸送各種非潤(rùn)滑性介質(zhì)。
4、采用同步齒輪驅(qū)動(dòng)，二轉(zhuǎn)子之間不接觸，即使短時(shí)間空轉(zhuǎn)也無(wú)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(jī)械密封或波紋管機(jī)械密封，具有壽命長(zhǎng)、泄漏少、適用范圍廣的特點(diǎn)。
2W.W密封型雙螺桿泵性能范圍
1、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(dá)到106mm2/s
介質(zhì)粘度對(duì)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(yàn)不充分時(shí)，建議按下列粘度條件選擇轉(zhuǎn)速：
介質(zhì)粘度cSt 轉(zhuǎn)速r/min
＜400 1500
400 ～
1200～3600 750
對(duì)于粘度更高的介質(zhì)，所應(yīng)選用的轉(zhuǎn)速和驅(qū)動(dòng)電機(jī)功率，請(qǐng)與制造廠聯(lián)系。
