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。 </p><p> 振動將加劇。如果缺點不是很嚴重，則調整基板和墊片可以進行糾正。直聯泵在進行維修之后常出現這種情況，這并非偶然現象。如果鑄鐵(優(yōu)先)或鋼沒有使用"底基層"，則使用所有螺紋埋于混凝土中的部件將電動機直接與地面相貼，在頂上使用螺母以緊固泵。由于這種裝置無法使用"后拉式結構"，通常需切削所有螺紋以便于移除泵的旋轉部件和電動機。這些螺紋很少更換，泵也不會直接與地面相接。振動和過早失效可能發(fā)生。c.系統(tǒng)共振——由于每一個系統(tǒng)都存在一些共振頻率，因此泵內的"可接受振動"將有可能導致系統(tǒng)頻率振動，放大共振頻率，從而加劇泵內的振動。這可能導致部件出現故障。與臨界轉速相似，需調整管道以解決這一問題。結論過量振動易于發(fā)現且能引起重大故障發(fā)生。確定振動產生的原因尤為重要，以便進行有效糾正。由于大多數振動產生的原因為外部原因或校準問題，因此應著重關注確定較長使用期限和較低壽命周期成本的調查。江蘇地區(qū)直銷離心泵——靖江市瑞鑫泵業(yè)有限公司。</p><div

src="https://tyunfile.71360.com/UploadFile/jjsrxby/637261023558720704/9336477.png"></div><p> 這些原因包括：a.泵和電動機未對準——這無可爭辯的是泵內產生振動的常見原因(其他原因，參考"外部原因引起的振動")。應該注意的是，按照泵生產商建議(而非聯軸器生產商的限制范圍)進行校準極為重要。(聯軸器通?？梢员缺没螂妱訖C承受的未校準值更大，但是負荷將傳送至泵或電動機。)b.旋轉不當——雖然在方向錯誤的情況下泵也將旋轉，但是流量和轉頭將減少，且由于流體動力學可能產生振動。旋轉應進行檢查并校正。(改變三相電動機的任意兩根導線，并在確認泵能以預期旋轉運行后檢查電動機上的標示牌以糾正單相電動機上的導線。)c.曲軸——曲軸可能由一些與場地有關的問題引起并能導致振動產生。通常情況下，曲軸將不相等負荷傳遞至軸承和閥座并引起過早磨損，即使在正常觀測實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確度或"擺度"相對較容易，因為框架形成了一個平臺，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，軸承也將出現磨損并因疲勞而出現故障。靖江市瑞鑫泵業(yè)有限公司——質量服務。臥式離心泵介質</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。江西防腐離心泵聯軸器</p><p
