起動前，自吸離心泵首先起動時要向泵體內注入一定量的起動循環(huán)水；而離心泵每次起動時剛需將進水管內及泵體內同時注滿水，或者用輔助裝置對進水管進行抽氣。2)裝置上，自吸離心泵在進水管下端只裝濾網而無底閥；而離心泵在進水管下端必須裝底閥或者在出口處配有抽氣裝置。3)運行時，同樣性能參數的泵，浙江自吸泵廠商，一般自吸離心泵要比離心泵的效率低，汽蝕性能較差。氣液混合式自吸離心泵工作時必須完成三個過程：將葉輪內的氣體往復帶出葉輪；有效地進液分離；分離出來的水不斷地返回到葉輪中去重新工作。根據水和氣體混合的部位不同，浙江自吸泵廠商，氣液混合式自吸離心泵分為內混式和外混式，浙江自吸泵廠商。其中氣液分離室中的水回流到葉輪進口處，氣體和水在葉輪進口處混合的稱內混式自吸離心泵。氣液分離室中的水回流到葉輪出口處，氣體和水在葉輪外緣處混合的稱外混式自吸離心泵。 </p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="浙江自吸泵廠商"

停泵1、首先必須關閉吐出管路上的閘閥。2、使泵停止轉動。3、在寒冷季節(jié)，應將泵體內的儲液和軸承體冷卻室內的水放空，以防凍裂機件。該泵均采用軸向回液的泵體結構。泵體由吸入室、儲液室、渦卷室、回液孔、氣液分離室等組成，泵正常起動后，葉輪將吸入室所存的液體及吸入管路中的空氣一起吸入，并在葉輪內得以完全混合，在離心力的作用，液體夾帶著氣體向渦卷室外緣流動，在葉輪的外緣上形成有一定厚度的白色泡沫帶及高速旋轉液環(huán)。氣液混合體通過擴散管進入氣液分離室。此時，由于流速突然降低，較輕的氣體從混合氣液中被分離出來，氣體通過泵體吐口繼續(xù)上升排出。脫氣后的液體回到儲液室，并由回流孔再次進入葉輪，與葉輪內部從吸入管路中吸入的氣體再次混合，在高速旋轉的葉輪作用下，又流向葉輪外緣......。隨著這個過程周而復始的進行下去，吸入管路中的空氣不斷減少，直到吸盡氣體，完成自吸過程，泵便投入正常作業(yè)。 </p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="浙江自吸泵廠商"

自吸泵的自吸是指在吸入管內不需要充滿水（但泵體內必須有足夠的水）的情況下起動泵，有自動排除吸人管內氣體的功能，經短時間運轉后進入正常工作。自吸泵在初次起動前必須灌人足夠的水，以后起動時則由留在泵體內的水再次起動進入正常工作。自吸泵根據結構及工作原理分為以下幾類：氣液混合式（內混式、外混式）；水環(huán)式自吸泵；射流式（水射流、氣體射流）。幾種自吸泵的性能比較如下：內混式自吸泵的效率比較高、制造成本低、自吸時間長、自吸高度低于10米、使用壽命長。外混式自吸泵的效率較低、制造成本中等、自吸時間較短、自吸高度低于10米、使用壽命長。水環(huán)式自吸泵的泵效率高、制造成本高、自吸時間短、自吸高度低于10米、使用壽命較短。射流式自吸泵的泵效率低、制造成本高、自吸時間短、自吸高度可以高于10米、使用壽命長。
