離心泵的常見故障機解決辦法：故障四：離心泵流量不足（1）系統(tǒng)靜揚程增加。處理方法是檢查液體高度和系統(tǒng)壓力。（2）阻力損失增加。處理方法是檢查管路及止逆閥等障礙。（3）殼體和葉輪耐磨環(huán)磨損過大。處理方法是更換或修理耐磨環(huán)及葉輪。（4）其他部位漏液。處理方法是檢查軸封等部位。（5）泵葉輪堵塞、磨損，江西耐酸離心泵參數(shù)、腐蝕。處理方法是清洗、檢查、調(diào)換。故障五：離心泵揚程不夠（1）葉輪裝反（雙吸輪）。處理方法是檢查葉輪。（2）液體密度、粘度與設計條件不符。處理方法是檢查液體的性質(zhì)。（3）操作時流量太大。處理方法是減少流量。故障六：運行過程**耗過大（1）葉輪與耐磨環(huán)、葉輪與殼有磨檫。處理方法是檢查并修理。（2）液體密度增加。處理方法是檢查液體密度。（3）填料壓得太緊或干磨擦。處理方法是放松填料，檢查水封管。（4）軸承損壞。處理方法是檢查修理或更換軸承。故障七：發(fā)生氣縛現(xiàn)象氣縛主要是由于離心泵在啟動前未充滿液體，泵殼內(nèi)存在空氣，空氣密度小，所產(chǎn)生的離心力也很小，此時在吸入口所形成的真空度不足以將液體吸入泵內(nèi)，泵氣動后不能輸送液體的現(xiàn)象。原因分析：①啟動前，未進行灌泵排氣，致使空氣竄入泵殼，江西耐酸離心泵參數(shù)，江西耐酸離心泵參數(shù)。②殼體的密封不嚴，使空氣竄入。江蘇地區(qū)直銷離心泵——靖江市瑞鑫泵業(yè)有限公司。江西耐酸離心泵參數(shù)</p><div

這些原因包括：a.泵和電動機未對準——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)進行校準極為重要。(聯(lián)軸器通常可以比泵或電動機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(zhuǎn)不當——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，且由于流體動力學可能產(chǎn)生振動。旋轉(zhuǎn)應進行檢查并校正。(改變?nèi)嚯妱訖C的任意兩根導線，并在確認泵能以預期旋轉(zhuǎn)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(chǎn)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(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。江西耐酸離心泵參數(shù)</p><p
