離心泵的工作原理,離心泵的結(jié)構(gòu)特點(diǎn)一、離心泵的結(jié)構(gòu)特點(diǎn)離心泵的結(jié)構(gòu)特點(diǎn)為：在一個蝸殼形的泵殼內(nèi)，安裝了一個可以快速旋轉(zhuǎn)的葉輪，在葉輪上有2～8片葉片。泵殼上有兩個接口，通向葉輪中心的是進(jìn)口，與吸人管路相接；在泵殼的切線方同的為出口，與排出管路相連接，如圖1-12所示。離心泵的主要工作部件是葉輪。其次是吸液室、泵體（泵殼）、泵蓋、軸封裝置（凄《及填料壓蓋或機(jī)械密封）、軸向力平衡裝置、軸承、聯(lián)軸器、托架、壓出室等。當(dāng)葉輪蓬i時，南京耐磨離心泵廠家，南京耐磨離心泵廠家，液體就能連續(xù)不斷地從吸入口吸人，從排出口排出，并使液體產(chǎn)生壓力而排送到高處：離心泵的結(jié)構(gòu)及組成常用離心泵類產(chǎn)品有如下：IS單級單吸離心泵ISG型立式單級管道離心泵ISW型直聯(lián)式單級臥式離心泵QDL不銹鋼高揚(yáng)程多級離心泵IH型化工**不銹鋼離心泵IHF耐酸襯氟化工離心泵二、離心泵的工作原理圖1-13所示為離心泵的工作原理示意圖，南京耐磨離心泵廠家。圖1-14所示為用雨天雨傘旋轉(zhuǎn)甩出傘面上的水來演示離心泵的工作原理。在啟動前，要先使液體從漏斗將泵殼與吸入管路內(nèi)灌滿。當(dāng)葉輪飛快旋轉(zhuǎn)時，葉輪內(nèi)的液體在葉輪內(nèi)葉片的推動下也跟著旋轉(zhuǎn)起來，從而使液體獲得了離心力，并沿著葉片流道從葉輪的中心往外運(yùn)動。江蘇銷售離心泵——靖江市瑞鑫泵業(yè)有限公司。南京耐磨離心泵廠家</p><div

這些原因包括：a.泵和電動機(jī)未對準(zhǔn)——這無可爭辯的是泵內(nèi)產(chǎn)生振動的常見原因(其他原因，參考"外部原因引起的振動")。應(yīng)該注意的是，按照泵生產(chǎn)商建議(而非聯(lián)軸器生產(chǎn)商的限制范圍)進(jìn)行校準(zhǔn)極為重要。(聯(lián)軸器通常可以比泵或電動機(jī)承受的未校準(zhǔn)值更大，但是負(fù)荷將傳送至泵或電動機(jī)。)b.旋轉(zhuǎn)不當(dāng)——雖然在方向錯誤的情況下泵也將旋轉(zhuǎn)，但是流量和轉(zhuǎn)頭將減少，且由于流體動力學(xué)可能產(chǎn)生振動。旋轉(zhuǎn)應(yīng)進(jìn)行檢查并校正。(改變?nèi)嚯妱訖C(jī)的任意兩根導(dǎo)線，并在確認(rèn)泵能以預(yù)期旋轉(zhuǎn)運(yùn)行后檢查電動機(jī)上的標(biāo)示牌以糾正單相電動機(jī)上的導(dǎo)線。)c.曲軸——曲軸可能由一些與場地有關(guān)的問題引起并能導(dǎo)致振動產(chǎn)生。通常情況下，曲軸將不相等負(fù)荷傳遞至軸承和閥座并引起過早磨損，即使在正常觀測實(shí)踐條件下這種磨損水平不足以被檢測到。誠然，在底腳固定框架式泵上檢查軸的準(zhǔn)確度或"擺度"相對較容易，因?yàn)榭蚣苄纬闪艘粋€平臺，便于檢查。所有故障部件的檢查通常將顯示引起故障的原因，包括在閥座和軸承內(nèi)的故障原因。d.軸承磨損/故障——正如其他討論所示，潤滑不足或潤滑不當(dāng)可以加速軸承磨損并引起振動。但是即使是在"完好"條件下，軸承也將出現(xiàn)磨損并因疲勞而出現(xiàn)故障。</p><p> 離心泵操作時應(yīng)注意以下幾點(diǎn)： </p> <p> ①禁止無水運(yùn)行，不要調(diào)節(jié)吸入口來降低排量，禁止在過低的流量下運(yùn)行； </p> <p> ②監(jiān)控運(yùn)行過程，徹底阻止填料箱泄漏，更換填料箱時要用新填料； </p> <p> ③確保機(jī)械密封有充分沖洗的水流，水冷軸承禁止使用過量水流； </p> <p> ④潤滑劑不要使用過多； </p> <p> ⑤按推薦的周期進(jìn)行檢查。建立運(yùn)行記錄，包括運(yùn)行小時數(shù)，填料的調(diào)整和更換，添加潤滑劑及其他維護(hù)措施和時間。對離心泵抽吸和排放壓力，流量，輸入功率，洗液和軸承的溫度以及振動情況都應(yīng)該定期測量記錄。 </p> <p> ⑥離心泵的主機(jī)是依靠大氣壓將低處的水抽到高處的，而大氣壓**多只能支持約10.3m的水柱，所以離心泵的主機(jī)離開水面12米無法工作。 </p> <p> <br /> </p> <br /> <p> <br /> 江蘇地區(qū)專業(yè)離心泵——靖江市瑞鑫泵業(yè)有限公司。</p><div style="width:100%;text-align: center;"><img

離心泵的特性曲線是泵本身固有的特性，它與外界使用情況無關(guān)。但是，一旦泵被安排在一定的管路系統(tǒng)中工作時，其實(shí)際工作情況就不僅與離心泵本身的特性有關(guān)，而且還取決于管路的工作特性。所以，要選好和用好離心泵，就還要同時考慮到管路的特性。 </p> <p> 在特定管路中輸送液體時，管路所需壓頭He隨著流量Qe的平方而變化。將此關(guān)系繪在坐標(biāo)紙上即為相應(yīng)管路特性曲線。 </p> <p> 若將離心泵的特性曲線與其所在管路特性曲線繪于同一坐標(biāo)紙上，如上圖所示，此兩線交點(diǎn)M稱為泵的工作點(diǎn)。選泵時，要求工作點(diǎn)所對應(yīng)的流量和壓頭既能滿足管路系統(tǒng)的要求，又正好是離心泵所提供的，即Q = Qe，H = He。江蘇地區(qū)質(zhì)量離心泵——靖江市瑞鑫泵業(yè)有限公司。南京耐磨離心泵廠家</p><p
