2W.W型雙螺桿泵通過(guò)泵體中主、從動(dòng)螺桿的相互嚙合,以及螺桿和泵體孔的配合,在泵體中形成一個(gè)個(gè)密封空腔,在螺桿轉(zhuǎn)動(dòng)時(shí),這些密封空腔連續(xù)向前移動(dòng),推動(dòng)密封腔中的液體到出口排出,實(shí)現(xiàn)輸送液體的目的。
雙螺桿泵優(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)。
3、外置軸承結(jié)構(gòu),采用潤(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、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)。
8、雙吸式結(jié)構(gòu),轉(zhuǎn)子上沒(méi)有軸向力。
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
