class="title">詳細說明</p><div id="rkmer2c" class="box"><p><p> (1)安裝傾角(θ)。安裝傾角指螺旋泵軸對水平面的夾角。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%。一般認為傾角在30°～40°為經(jīng)濟。 </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。實驗資料證明：螺旋泵的外徑較大時，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。對于一定直徑的螺旋泵，每增加一個葉片頭數(shù)，提升能力約增加20%。 </p> <p> (7)導(dǎo)程和螺距，廣州螺桿泵銷售公司，廣州螺桿泵銷售公司，廣州螺桿泵銷售公司。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?；n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 /> 單螺桿泵流量均勻壓力穩(wěn)定，低轉(zhuǎn)速時更為明顯.廣州螺桿泵銷售公司</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="廣州螺桿泵銷售公司,螺桿泵"

第三梯度是國內(nèi)企業(yè)產(chǎn)品。國內(nèi)螺桿泵企業(yè)在技術(shù)上和品牌上處于劣勢，只能通過壓低價格、提高服務(wù)質(zhì)量、減少交貨周期來贏得客戶，因而價格往往比進口螺桿泵要低20％－30％。 </p> <p> <br /> </p> <p> <br /> </p> <p> <br /> </p> <p> 從產(chǎn)品結(jié)構(gòu)來看，螺桿泵產(chǎn)品種類較多，規(guī)格復(fù)雜，價格跨度較大。加上一些中小企業(yè)以低廉的價格進行惡性競爭，擾亂了市場價格。一般而言，原材料等級越高、產(chǎn)品規(guī)格越高的螺桿泵價格更高。分種類而言，三螺桿泵結(jié)構(gòu)簡單，便于維修，價格也相對較低。雖然我國國內(nèi)的螺桿泵與國外專業(yè)公司相比還存在差距，但隨著我國螺桿泵科研力量的投入及應(yīng)用實踐的增多，螺桿泵未來發(fā)展趨勢是開發(fā)低轉(zhuǎn)速，長導(dǎo)程，傳動量部件材質(zhì)優(yōu)良，額定壽命長的產(chǎn)品替代原來傳統(tǒng)螺桿泵。

螺桿泵由于其結(jié)構(gòu)特點，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120攝氏度，如果采用高溫120攝氏度—350攝氏度時可定制。由于該二部件的特殊幾何開頭分別形成單獨的密封容腔。介質(zhì)由軸向均勻推行流動。內(nèi)部流速代低，容積保持不變。螺桿泵壓力穩(wěn)定，因而不會產(chǎn)品渦流和攪動。每級泵的輸出壓力為0.6MPa—1.2MPa，揚程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轉(zhuǎn)時間，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。 </p> <p> <br /> </p><p> <br /> </p> <p> <br /> </p>

</p> <p> （2）檢查各軸承的潤滑油是否充足，潤滑油是否變質(zhì)； </p> <p> <br /> </p> <p> （3）如果是***次使用或重新安裝的水螺桿泵，應(yīng)檢查水螺桿泵的轉(zhuǎn)動方向是否正確； </p> <p> <br /> </p> <p> （4）檢查吸液池及濾網(wǎng)上是否有雜物； </p> <p> <br /> </p> <p>

化學(xué)腐蝕是指金屬與干燥的氣體或非電解質(zhì)溶液產(chǎn)生化學(xué)作用而引起的腐蝕。化學(xué)腐蝕通常為干腐蝕，腐蝕速度相對較小。如碳鋼在鑄造、鍛造、熱處理過程中發(fā)生的高溫氧化以及鋁在無水乙醇中的腐蝕等均屬于此類腐蝕。實際上單純的化學(xué)腐蝕是相當(dāng)少的，一些干燥介質(zhì)中如混人水分常會由化學(xué)腐蝕轉(zhuǎn)化為電化學(xué)腐蝕。
