管道泵具有以下特點：1、管道泵結(jié)構(gòu)緊湊，機泵一體化，體積小。其立式結(jié)構(gòu)具有安裝占地面積小。運行平穩(wěn)，安裝無需調(diào)整。2、泵進出口設(shè)計成規(guī)格相同法蘭，且位于同一中心在線，可象閥門一樣直接安裝在管路上，且中心低，便于管道布置，安裝方便。3、泵與電機同軸，軸向尺寸短，使泵運行更加平穩(wěn)，噪音低。4、取消傳統(tǒng)軸封方式，避免了輸送介質(zhì)的外泄，因此具有完全無泄漏的特點。管道泵的作用管道離心泵是為管道增壓輸送，解決管道壓力過低而研制的新穎泵，比目前應(yīng)用臥式離心泵具有很大的優(yōu)越性。管道泵的優(yōu)越性主要體現(xiàn)在以下幾點：1．管道泵適用于高層建筑增壓送水、園林噴灌、冷卻塔上水、遠距離輸水、空調(diào)、制冷沖洗、浴室等冷；暖水循環(huán)加壓。使用溫度80℃以下。2．管道泵適用于采暖、鍋爐等行業(yè)的高溫?zé)崴鰤貉h(huán)。使用溫度150℃以下。3．管道泵適用于輸送食品、制藥、造酒、化工等行業(yè)的工藝流程中腐蝕性介質(zhì)，使用溫度80℃以下。4．管道泵適用于輸送無腐蝕性液體，有甲烷或煤礦井下固定設(shè)備I類及工廠IIA、IIB級，溫度組別為T1、T2、T3、T4組存在性混合物的其它工業(yè)場所。使用溫度80℃以下。5．管道泵適用于輸送化工、制藥、石油、食品、**等工業(yè)腐蝕性液體。</p><p>

這種由于泵內(nèi)存有空氣造成離心泵不能吸液的現(xiàn)象稱為氣縛現(xiàn)象，如圖1-16所示。因此，離心泵在啟動前必須將泵體和吸人管內(nèi)灌滿液體或抽出空氣。離心泵裝置安裝示意圖離心泵的氣蝕現(xiàn)象離心泵沒有自吸能力，所以在啟動離心泵前必須灌泵，為防止灌入泵殼內(nèi)的液體因重力流人低位槽內(nèi)，在泵吸人管路的入口處裝有止逆閥（底閥）。如果泵的位置低于槽內(nèi)液面，則啟動前無需人工灌泵，借助位差液體可自動流人泵內(nèi)。在生產(chǎn)中，有時雖灌泵，卻仍然存在不能吸液的現(xiàn)象，可能是由以下原因造成的。(1)吸人管路的連接法蘭不嚴密，漏人空氣。(2)灌而未滿，未排凈空氣，泵殼或管路中仍有空氣存在。(3)吸人管底閥失靈或關(guān)不嚴，灌液不滿。(4)吸人管底閥或濾網(wǎng)被堵塞。(5)吸入管底閥未打開或失靈等，可根據(jù)具體情況，可采取相應(yīng)的措施加以克服。如果水位比泵低很多建議選用自吸泵、常規(guī)的自吸泵產(chǎn)品自吸高度只有4-5米，如果超過5米在9米以內(nèi)的建議選用博禹泵業(yè)的：真空輔助高吸程自吸泵離心泵安裝方法，離心泵安裝注意事項一、離心泵安裝注意事項關(guān)鍵安裝技術(shù)管道離心泵的安裝技術(shù)關(guān)鍵在于確定離心泵安裝高度即吸程。這個高度是指水源水面到離心泵葉輪中心線的垂直距離。江蘇離心泵——靖江市瑞鑫泵業(yè)有限公司。徐州耐磨離心泵配件</p><p

H——Q往上移，工作點由M移至M1，流量由QM加大到QM1。若把泵的轉(zhuǎn)速降至n2，工作點移至M2，流量降至QM2。 </p> <p> 這種調(diào)節(jié)方法需要變速裝置或價格昂貴的變速原動機，且難以做到連續(xù)調(diào)節(jié)流量，故化工生產(chǎn)中很少采用。 </p> <p> 用閥門調(diào)節(jié)流量迅速方便，且流量可以連續(xù)變化，適合化工連續(xù)生產(chǎn)的特點。所以應(yīng)用十分廣。缺點是閥門關(guān)小時，阻力損失加大，能量消耗增多，很不經(jīng)濟。無錫大型離心泵流量</p><p
