class="title">詳細(xì)說明</p><div id="wo8xtpv" class="box"><p><p> 螺桿泵轉(zhuǎn)速的選擇： </p> <p> 螺桿泵由于其結(jié)構(gòu)特點(diǎn)，大部分使用在輸送較高粘度的液體及含有顆粒的液體，因此其轉(zhuǎn)數(shù)的選擇非常關(guān)鍵，螺桿泵零件少，結(jié)構(gòu)緊湊，體積小，維修簡單，螺桿泵轉(zhuǎn)子和定子是螺桿泵的易損件，結(jié)構(gòu)簡單，便于裝拆。是按迥轉(zhuǎn)嚙合容積式原理工作的新型泵種。主要工作部件是偏心螺桿（轉(zhuǎn)子）和固定的襯套（定子）。采用***無味的食用橡膠，工作溫度可達(dá)120攝氏度，如果采用高溫120攝氏度—350攝氏度時(shí)可定制。由于該二部件的特殊幾何開頭分別形成單獨(dú)的密封容腔。介質(zhì)由軸向均勻推行流動(dòng)。內(nèi)部流速代低，廣州螺桿泵誠邀品鑒，容積保持不變，廣州螺桿泵誠邀品鑒。螺桿泵壓力穩(wěn)定，因而不會(huì)產(chǎn)品渦流和攪動(dòng)。每級(jí)泵的輸出壓力為0.6MPa—1.2MPa，揚(yáng)程60m—120m（清水），自吸高度一般在3m以上。 </p> <p> 螺桿泵如何保持高效率 </p> <p> 如何保持螺桿泵高效率，螺桿泵的容量大于井的產(chǎn)量或泵吸入口處氣分離不好，一部分泵排量受氣干擾而損失，如果消除泵內(nèi)氣的干擾和控制泵的運(yùn)轉(zhuǎn)時(shí)間，使泵排量與流入井底的液量相匹配，就可以提高效率和降低成本，廣州螺桿泵誠邀品鑒。 </p> <p> <br />

src="http://tyunfile.71360.com/UploadFile/qunxun/637211876900478515/127892.jpg"></div><p> 與葉片泵相比較，螺旋泵具有以下優(yōu)點(diǎn)： </p> <p> ①轉(zhuǎn)速低(一般為20r/min～90r/min)，機(jī)械磨損小，不會(huì)發(fā)生汽蝕。 </p> <p> ②流道寬，可以輸送含有固體物的水。 </p> <p> ③泵體結(jié)構(gòu)是半開的，可以觀察到泵內(nèi)的運(yùn)行情況。 </p> <p> ④吸入側(cè)流態(tài)對(duì)水力性能影響甚微，對(duì)吸水池?zé)o特殊要求，基礎(chǔ)開挖深度小，水工建筑物施工簡單，土建費(fèi)用少。 </p> <p> 其缺點(diǎn)是： </p> <p> ①尺寸大，占地面積也大。 </p> <p> ②受機(jī)械加工條件限制，泵軸不能太長，因而揚(yáng)程較低，一般不超過10m。 </p> <p> ③吸水面、出水面高度變化不能太大，否則會(huì)影響工作效率，增加能耗。 </p> <p> <br /> 肇慶原裝螺桿泵特點(diǎn)是流量平穩(wěn)、壓力脈動(dòng)小、有一定自吸能力、噪聲低、效率高、壽命長、工作可靠。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="廣州螺桿泵誠邀品鑒,螺桿泵" src="http://tyunfile.71360.com/UploadFile/qunxun/637211876904726562/9106620.jpg"></div><p> 2、單螺桿泵的運(yùn)行 </p> <p> 螺桿泵必須按規(guī)定的方向工作，以產(chǎn)生一定的吸力和流量。在工作時(shí)，應(yīng)檢查壓力、溫度和機(jī)械密封。對(duì)于軸封，應(yīng)有輕微泄漏。如果泄漏量不超過20-30秒/滴，則認(rèn)為是正常的。如果螺桿泵在工作中產(chǎn)生噪聲，則經(jīng)常是由于油溫度低、油粘度高、油中空氣、耦合損失和泵的過度磨損造成的。 </p> <p> <br /> </p> <p> 3、單螺桿泵停車 </p> <p> 螺桿泵停止后，首先關(guān)閉排氣停止閥，關(guān)閉泵后關(guān)閉吸入截止閥。由于螺桿長度大，剛性差，螺桿泵容易產(chǎn)生彎曲，造成異常工作，軸系統(tǒng)的連接必須良好，中間工作比較好是在安裝和定位后進(jìn)行，避免管路連接。應(yīng)引起變形，連接管應(yīng)**固定，盡可能減少泵的連接等，另外，備用螺絲比較好在存放期間懸掛和固定，以避免因放置不均勻引起的變形。 </p> <p> <br /> </p> <p> <br /> </p><p> <br /> </p> <p> <br /> </p> <p> <br /> </p> <p> <br /> </p> <p> 3.水泵不出水： </p> <p> <br /> </p> <p> 產(chǎn)生原因：泵體和吸水管沒灌滿引水；動(dòng)水位低于水泵濾水管；吸水管破裂等。螺桿泵因其有可變量輸送、自吸能力強(qiáng)、可逆轉(zhuǎn)、能輸送含固體顆粒的液體等特點(diǎn)，在污水處理廠中，***地被使用在輸送水、濕污泥和絮凝劑藥液方面。螺桿泵選用應(yīng)遵循經(jīng)濟(jì)、合理、可靠的原則。如果在設(shè)計(jì)選型方面考慮不周，會(huì)給以后的使用、管理、維修帶來麻煩，所以選用一臺(tái)按生產(chǎn)實(shí)際需要，合理可靠的螺桿泵既能保證生產(chǎn)順利進(jìn)行，又可降低修理成本。

(1)安裝傾角(θ)。安裝傾角指螺旋泵軸對(duì)水平面的夾角。它直接影響泵的效率和流量。據(jù)有關(guān)資料介紹，傾角每增加一度，效率大約降低3%。一般認(rèn)為傾角在30°～40°為經(jīng)濟(jì)。 </p> <p> (2)間隙。間隙指螺旋葉片與外殼之間的間隙。間隙越小，水漏損失就越小，泵的效率就越高。 </p> <p> (3)轉(zhuǎn)速(n)。螺旋泵的轉(zhuǎn)速較慢，一般為20～80 r/min。實(shí)驗(yàn)資料證明：螺旋泵的外徑較大時(shí)，轉(zhuǎn)速宜減小。 </p> <p> (4)提升高度(H)。螺旋泵只有提升高度，而沒有壓水高度。它的提升高度一般為3～8 m。 </p> <p> (5)螺旋葉片直徑(D)。泵的葉片直徑越大，其效率越高，螺旋泵的葉片直徑與泵軸直徑的比較好比例為2:1。 </p> <p> (6)頭數(shù)(Z)。頭數(shù)指螺旋葉片的片數(shù)，一般為1～4片。它們相隔一定的間距環(huán)繞泵軸螺旋上升。頭數(shù)越多，泵效率也越高。對(duì)于一定直徑的螺旋泵，每增加一個(gè)葉片頭數(shù)，提升能力約增加20%。 </p> <p> (7)導(dǎo)程和螺距。螺旋葉片環(huán)繞泵軸螺旋上升360°所經(jīng)軸向距離，即為一個(gè)導(dǎo)程λ。螺距S和導(dǎo)程λ的關(guān)系如下： </p> <p> <br /> </p> <p> (8)流量(Q)和軸功率(N)。流量可按下式計(jì)算： </p> <p> <br /> </p> <p> 軸功率為 </p> <p> <br /> </p> <p> 式中：D為葉片外徑(m)；d為泵軸直徑(m)；S為螺距(m)；α為提水?dāng)嗝媛剩籲為轉(zhuǎn)速(r/min)；η為泵的效率(%)；ρ為所提升的液體密度(kg/m3)；Q為流量(m3/s)；H為提升高度(m)。 </p> <p> <br /> 無效的泵運(yùn)轉(zhuǎn)常是氣干擾造成的，可通過聲波液面測量和示功圖進(jìn)行診斷。梅州螺桿泵誠信為本</p><p
