雙螺桿泵選型步驟：
雙螺桿泵和三螺桿泵單螺桿泵的選型步驟有所不同，
1.雙螺桿泵和三螺桿泵的區(qū)別就是雙螺桿泵能輸送各種具有流動(dòng)性的液體和沒(méi)有流動(dòng)性的固體，介質(zhì)潤(rùn)滑性的好壞對(duì)于雙螺桿泵來(lái)說(shuō)顯得就不是那么的重要，對(duì)輸送有腐蝕性的介質(zhì)我們將采用不銹鋼材質(zhì)為客戶訂制適合您現(xiàn)場(chǎng)使用產(chǎn)品，國(guó)產(chǎn)的三螺桿泵和雙螺桿泵相比就顯得比較嬌貴，三螺桿泵一般適合輸送各種潤(rùn)滑性良好無(wú)腐蝕性的介質(zhì)，對(duì)于輸送重油，柴油，等潤(rùn)滑性差的介質(zhì)三螺桿泵就要采用外置機(jī)械密封，盡管外置機(jī)械密封是避免了因?yàn)槟p而造成機(jī)械密封漏油的情況發(fā)生，但是避免不了螺桿與螺桿摩擦，長(zhǎng)期輸送潤(rùn)滑性差介質(zhì)，會(huì)使螺桿磨損 ，就會(huì)造成泵的壓力上不去，流量損失等，對(duì)三螺桿泵的使用壽命造成嚴(yán)重威脅。
2.雙螺桿泵輸送的流量范圍廣，從1 m3/h到8600 m3/h，而三螺桿泵的流量1m3/h到600m3/h，所以在許多油田上用大流量原油輸送泵和船舶上用主機(jī)潤(rùn)滑泵，貨油泵三螺桿泵很少被列入設(shè)計(jì)院選型范圍之內(nèi)。
3.雙螺桿泵能承受的溫度范圍廣，從~20°C到500°C，而三螺桿泵承受的溫度范圍~10°C到200°C。
4.雙螺桿泵的應(yīng)用行業(yè)廣：
雙吸雙螺桿泵、雙螺桿泵、高溫髙粘雙螺桿泵優(yōu)點(diǎn)
1、雙螺桿泵具有流量大，自吸能力好，噪聲低，壽命長(zhǎng)，配置形式多，適應(yīng)性廣。
2、有很強(qiáng)的自吸性能，多相混輸時(shí)，含氣率不高于60％，雙螺桿泵適用于具有潤(rùn)滑性無(wú)固體雜質(zhì)的各種油品的輸送，雙螺桿泵適用于不含固體雜質(zhì)的各種介質(zhì)的輸送包含各種油品化學(xué)品及高分子物料的輸送。
3、外置軸承結(jié)構(gòu)，采 用獨(dú)立潤(rùn)滑，允許輸送各種非潤(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(méi)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、適用范圍廣等特點(diǎn)。
雙螺桿泵、雙吸雙螺桿泵結(jié)構(gòu)特點(diǎn)
該型雙螺桿泵采用雙吸式結(jié)構(gòu)，螺桿兩端處于同一壓力腔中，軸向力可以自行平衡。兩端軸承采用外裝式，單獨(dú)采用潤(rùn)滑油（脂）潤(rùn)滑，因而不受輸送介質(zhì)的影響，兩螺桿間用一對(duì)同步齒輪驅(qū)動(dòng)，螺桿齒面間并不接觸，而留有一微小間隙，介質(zhì)中的雜質(zhì)并不能對(duì)螺桿齒面產(chǎn)生直接的磨損（除沖刷外）。
一般在泵體上都帶有內(nèi)流式安全閥，當(dāng)排放壓力超過(guò)額定值時(shí)，有一定保護(hù)作用。泵體上的進(jìn)出口方向有二種，一為水平出；二為水平進(jìn)，垂直向上出；用戶可根據(jù)自己需要選擇。
