class="title">詳細(xì)說明</p><div id="hf9djx7" 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(rèn)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)，佛山螺桿泵生產(chǎn)廠商，提升能力約增加20%。 </p> <p> (7)導(dǎo)程和螺距，佛山螺桿泵生產(chǎn)廠商。螺旋葉片環(huán)繞泵軸螺旋上升360°所經(jīng)軸向距離，佛山螺桿泵生產(chǎn)廠商，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 />

式中，Gv為容積效力，％；Qin為額外壓力點規(guī)則轉(zhuǎn)速下的體積流量，m3÷h；Qon為零壓力點規(guī)則轉(zhuǎn)速下的體積流量，m3÷h。 </p> <p> 對螺桿泵實踐排量提出了明白的判斷方式和盤算公式。 </p> <p> 肯定了容積效力準(zhǔn)確的盤算公式，倡議各廠家實驗用測試順序盤算公式嚴(yán)厲遵照請求編寫。倡議展開螺桿泵實踐泵腔體積與泵型標(biāo)注幾何排量偏向的檢測與鉆研，對定轉(zhuǎn)子配合尺寸進(jìn)行嚴(yán)厲檢測，給出一個許可的偏向規(guī)模和質(zhì)量判斷方式。關(guān)于螺桿泵容積效力偏向發(fā)生起因之一的流量測試問題，倡議驗證流量測量值，在測試流程中串聯(lián)一個流量計進(jìn)行流量對照。 </p> <p> 倡議在螺桿泵性能檢測中對實踐排量和容積效力兩特征能參數(shù)進(jìn)行**檢測，并用文中給出的方式和公式進(jìn)行判斷。污水提升器污水提升泵污水提升裝置污水提升器 </p> <p> <br /> 東莞螺桿泵聯(lián)系人要求輸送壓力穩(wěn)定，介質(zhì)固有結(jié)構(gòu)不受破壞時，選用單螺桿泵輸送**為理想。</p><div

1、應(yīng)進(jìn)行聲波液面測定，確定產(chǎn)液面與泵吸入口的相對深度。若液面高于泵吸入口，那么井不可能以比較大產(chǎn)量開采。如果是氣干擾影響產(chǎn)率，則液面高于泵吸入口；若是抽量過大導(dǎo)致低產(chǎn)，則液面應(yīng)在泵吸入口處或附近。 </p> <p> 2、測定泵充滿系數(shù)百分率，應(yīng)用綜合數(shù)據(jù)采集系統(tǒng)可同時獲得馬達(dá)功率和示功數(shù)據(jù)。主要用途之一是診斷泵是怎樣運行的和分析井下問題。應(yīng)用生產(chǎn)液面測量結(jié)合示功圖可了解井是否以比較大產(chǎn)量生產(chǎn)、液柱高度是否高于泵吸入口深度、螺桿泵是否不完全充滿和游離氣是否沿套管環(huán)空向上運移。

經(jīng)過***檢查，確認(rèn)一切正常后，才可作啟動的準(zhǔn)備工作。應(yīng)有以下幾項工作。 </p> <p> <br /> </p> <p> <br /> </p> <p> <br /> </p> <p> （1）關(guān)閉排水管路上的閥門，以降低啟動電流； </p> <p> <br /> </p> <p> <br /> </p> <p> <br /> </p> <p> （2）打開放氣旋塞，向水螺桿泵內(nèi)灌水，同時用手轉(zhuǎn)動聯(lián)軸器，使葉輪內(nèi)殘存的空氣盡可能排出，直至放氣旋塞有水冒出時，再將其關(guān)閉； </p> <p> <br /> </p> <p> <br /> </p> <p> <br /> </p> <p> （3）大型水螺桿泵用真空螺桿泵抽氣灌水時，應(yīng)關(guān)閉放氣旋塞及真空表和壓力表的旋塞，以保護(hù)儀表的準(zhǔn)確性。 3.啟動 </p> <p> <br /> </p> <p> <br /> </p> <p> <br /> </p> <p> 完成以上準(zhǔn)備工作后，便可啟動螺桿泵。啟動后待水螺桿泵轉(zhuǎn)速穩(wěn)定，電流表指針擺動到指定位置，這時再把真空表及壓力表的旋塞打開，并慢慢開啟出口閥門，水螺桿泵進(jìn)人正常運行。與此同時還應(yīng)將水封管的閥門打開。 </p> <p> <br /> </p> <p> <br /> </p> <p> <br /> </p> <p> 螺桿泵啟動后空轉(zhuǎn)時間不能太長，通常以2～4min為限，如果時間過長，水的溫度就會升高，可能導(dǎo)致汽蝕現(xiàn)象或其他不良后果。 </p> <p> <br /> </p> <p> <br /> </p> <p> <br /> </p> <p> <br /> 將吸入室中的液體封入其中，并自吸入室沿螺桿軸向連續(xù)地推移至排出端。</p><div
