這種由于泵內存有空氣造成離心泵不能吸液的現象稱為氣縛現象，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，為防止灌入泵殼內的液體因重力流人低位槽內，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。在生產中，有時雖灌泵，卻仍然存在不能吸液的現象，江西工業(yè)離心泵聯軸器，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，江西工業(yè)離心泵聯軸器。(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不嚴，灌液不滿。(4)吸人管底閥或濾網被堵塞。(5)吸入管底閥未打開或失靈等，可根據具體情況，可采取相應的措施加以克服。如果水位比泵低很多建議選用自吸泵、常規(guī)的自吸泵產品自吸高度只有4-5米，如果超過5米在9米以內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鍵安裝技術管道離心泵的安裝技術關鍵在于確定離心泵安裝高度即吸程，江西工業(yè)離心泵聯軸器。這個高度是指水源水面到離心泵葉輪中心線的垂直距離。江蘇地區(qū)進口離心泵——靖江市瑞鑫泵業(yè)有限公司。江西工業(yè)離心泵聯軸器</p><div

離心泵的工作原理,離心泵的結構特點一、離心泵的結構特點離心泵的結構特點為：在一個蝸殼形的泵殼內，安裝了一個可以快速旋轉的葉輪，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《及填料壓蓋或機械密封）、軸向力平衡裝置、軸承、聯軸器、托架、壓出室等。當葉輪蓬i時，液體就能連續(xù)不斷地從吸入口吸人，從排出口排出，并使液體產生壓力而排送到高處：離心泵的結構及組成常用離心泵類產品有如下：IS單級單吸離心泵ISG型立式單級管道離心泵ISW型直聯式單級臥式離心泵QDL不銹鋼高揚程多級離心泵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。圖1-14所示為用雨天雨傘旋轉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灌滿。當葉輪飛快旋轉時，葉輪內的液體在葉輪內葉片的推動下也跟著旋轉起來，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動。無錫防腐離心泵功率江蘇地區(qū)直銷離心泵——靖江市瑞鑫泵業(yè)有限公司。</p><div

泵不吸水故障分析：吸入閥有雜物或未打開，或吸入管堵塞管路系統(tǒng)密封性差從軸封處吸入空氣灌泵系統(tǒng)故障解決方法：打開吸入閥，排除雜物，疏通吸入管。檢察管路，尤其分段試壓連接法蘭處，堵漏。更換軸封，壓緊填料密封檢查及維修灌泵系統(tǒng)02泵不能啟動故障分析：原動機發(fā)生故障（包括電源）；泵卡??；填料函壓得太緊；排出閥門未關。解決方法：檢查電源及原動機情況；再次盤車確定聯軸器情況；放松填料；管進出口閥門，再次啟動。03泵不排液故障分析：灌泵不足（或泵內氣體未排凈）；泵轉向不對；泵轉速太低；濾網、吸入管堵塞；吸入高度太高，或吸入口液體供給不足，造成吸入真空。解決方法：重新灌泵；再次確定泵的旋轉方向；檢查電機空轉轉速，檢查減速器的減速比，確定泵轉速是否符合設計轉速；清洗濾網，疏通吸入管；調整吸入口管線，高于泵的入口，調整泵的上部供液系統(tǒng)，保證介質供應充分。</p><p> 它與允許吸上真空高度不能混為一談，水泵產品說明書或銘牌上標示的允許吸上真空高度是指水泵進水口斷面上的真空值，而且是在1標準大氣壓下、水溫20℃情況下，進行試驗而測定得的。它并沒有考慮吸水管道配套以后的水流狀況。而水泵安裝高度應該是允許吸上真空高度扣除了吸水管道損失揚程以后，所剩下的那部分數值，它要克服實際地形吸水高度。水泵安裝高度不能超過計算值，否則，離心泵將會抽不上水來。另外，影響計算值的大小是吸水管道的阻力損失揚程，因此，宜采用zui短的管路布置，并盡量少裝彎頭等配件，也可考慮適當配大一些口徑的水管，以減管內流速。應當指出，管道離心泵安裝地點的高程和水溫不同于試驗條件時，如當地海拔300米以上或被抽水的水溫超過20℃，則計算值要進行修正。即不同海拔高程處的大氣壓力和高于20℃水溫時的飽和蒸汽壓力。但是，水溫為20℃以下時，飽和蒸汽壓力可忽略不計。從管道安裝技術上，吸水管道要求有嚴格的密封性，不能漏氣、漏水，否則將會破壞離心泵進水口處的真空度，使離心泵出水量減少，嚴重時甚至抽不上水來。因此，要認真地做好管道的接口工作，保證管道連接的施工質量。江蘇地區(qū)口碑好離心泵生產廠家——靖江市瑞鑫泵業(yè)有限公司。</p><div

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。但是，一旦泵被安排在一定的管路系統(tǒng)中工作時，其實際工作情況就不僅與離心泵本身的特性有關，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。將此關系繪在坐標紙上即為相應管路特性曲線。 </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紙上，如上圖所示，此兩線交點M稱為泵的工作點。選泵時，要求工作點所對應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)定制離心泵——靖江市瑞鑫泵業(yè)有限公司。江西工業(yè)離心泵聯軸器</p><p

將需要增加NPSH或排空現有系統(tǒng)內的攜入空氣。c.腐蝕和沖蝕——雖然腐蝕和沖蝕問題極易被視為"內部問題"，但是其根源在于為泵的抽送能力選擇材料時的不當。腐蝕或沖蝕產生的損壞可能毀壞葉輪或頸環(huán)，導致機械的振動超出限度。需分析泵的抽送能力才能解決這一問題。即使受沙礫沖蝕較厲害，仍需按照步驟更換材料以根除問題或延長MTBF。d.葉輪的不平衡——按照ISO標準1940/1，葉輪應該切割到大運行速度時的恰當直徑并實現動態(tài)平衡()，該平衡級允許轉速為1800時每盎司泵輪重量產生(轉速為3600時為)。如果在現有泵上切割葉輪，按照標準平衡葉輪時出現初始故障或重新平衡失敗將導致振動超出可接受的范圍。這一點在各種大、小機械上均很重要，因為已建立的標準考慮了機械的總質量以及葉輪對振動產生的影響。的解決方法是拆掉葉輪重新進行平衡。e.電動機轉動元件的不平衡——這是一種少見的制造缺點。有關電動機平衡測試要求請見美國電氣制造業(yè)協(xié)會(NEMA)的標準MG-12007第1節(jié)第7部分。通常情況下，被確定為電動機轉子不平衡(通過斷開電動機并由其自行運轉)的問題實際上是曲軸或軸承故障問題，該內容已在本文其他部分進行討論。電動機旋轉部分的不平衡實際上在啟動時。江西工業(yè)離心泵聯軸器</p><p
