離心泵的常見(jiàn)故障機(jī)解決辦法：故障四：離心泵流量不足（1）系統(tǒng)靜揚(yáng)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(guò)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、腐蝕。處理方法是清洗、檢查、調(diào)換。故障五：離心泵揚(yáng)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(shè)計(jì)條件不符。處理方法是檢查液體的性質(zhì)。（3）操作時(shí)流量太大。處理方法是減少流量。故障六：運(yùn)行過(guò)程**耗過(guò)大（1）葉輪與耐磨環(huán)、葉輪與殼有磨檫，上海耐堿離心泵臥式。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，上海耐堿離心泵臥式，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(dòng)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(shí)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(dòng)后不能輸送液體的現(xiàn)象。原因分析：①啟動(dòng)前，未進(jìn)行灌泵排氣，致使空氣竄入泵殼。②殼體的密封不嚴(yán)，使空氣竄入，上海耐堿離心泵臥式。離心泵廠家，歡迎您的來(lái)電咨詢——靖江市瑞鑫泵業(yè)有限公司。上海耐堿離心泵臥式</p><div

改變離心泵出口管線上的閥門開(kāi)關(guān)，其實(shí)質(zhì)是改變管路特性曲線。如下圖所示，當(dāng)閥門關(guān)小時(shí)，管路的局部阻力加大，管路特性曲線變陡，工作點(diǎn)由M移至M1，流量由QM減小到QM1。當(dāng)閥門開(kāi)大時(shí)，管路阻力減小，管路特性曲線變得平坦一些，工作點(diǎn)移至M2，流量加大到QM2。 </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(diǎn)。所以應(yīng)用十分廣。缺點(diǎn)是閥門關(guān)小時(shí)，阻力損失加大，能量消耗增多，很不經(jīng)濟(jì)。常州管道離心泵效率江蘇地區(qū)口碑好離心泵生產(chǎn)廠家——靖江市瑞鑫泵業(yè)有限公司。</p><div
