閉式和半閉式葉輪在運(yùn)轉(zhuǎn)時，離開葉輪的一部分高壓液體可漏入葉輪與泵殼之間的空腔中，因葉輪前側(cè)液體吸入口處壓強(qiáng)低，故液體作用于葉輪前、后側(cè)的壓力不等，便產(chǎn)生了指向葉輪吸入口側(cè)的軸向推力。 </p> <p> <br /> </p> <p> <br /> </p> <p> 該力推動葉輪向吸入口側(cè)移動，引起葉輪和泵殼接觸處的摩損，嚴(yán)重時造成泵的振動，破壞泵的正常操作。在葉輪后蓋板上鉆若干個小孔，可減少葉輪兩側(cè)的壓力差，從而減輕了軸向推力的不利影響，但同時也降低了泵的效率。這些小孔稱為平衡孔。新疆自吸耐腐蝕離心泵批發(fā)價(jià)格耐腐蝕離心泵哪家質(zhì)量優(yōu)，瑞鑫值得信賴，期待您的來電！</p><div

利用離心力輸水的想法**早出現(xiàn)在列奧納多·達(dá)芬奇所作的草圖中。1689年，法國物理學(xué)家帕潘發(fā)明了四葉片葉輪的蝸殼離心泵。但更接近于現(xiàn)代離心泵的，則是1818年在美國出現(xiàn)的具有徑向直葉片、半開式雙吸葉輪和蝸殼的所謂馬薩諸塞泵。1851～1875年，帶有導(dǎo)葉的多級離心泵相繼被發(fā)明，使得發(fā)展高揚(yáng)程離心泵成為可能。 </p> <p> 盡管早在1754年，瑞士數(shù)學(xué)家歐拉就提出了葉輪式水力機(jī)械的基本方程式，奠定了離心泵設(shè)計(jì)的理論基礎(chǔ)，但直到19世紀(jì)末，高速電動機(jī)的發(fā)明使離心泵獲得理想動力源之后，它的優(yōu)越性才得以充分發(fā)揮。在英國的雷諾和德國的普夫萊德雷爾等許多學(xué)者的理論研究和實(shí)踐的基礎(chǔ)上，離心泵的效率**提高，它的性能范圍和使用領(lǐng)域也日益擴(kuò)大，已成為現(xiàn)代應(yīng)用**廣、產(chǎn)量比較大的泵。

需要強(qiáng)調(diào)指出的是，若在離心泵啟動前沒向泵殼內(nèi)灌滿被輸送的液體，由于空氣密度低，葉輪旋轉(zhuǎn)后產(chǎn)生的離心力小，葉輪中心區(qū)不足以形成吸入貯槽內(nèi)液體的低壓，因而雖啟動離心泵也不能輸送液體。這表明離心泵無自吸能力，此現(xiàn)象稱為氣縛。 </p> <p> 吸入管路安裝單向底閥是為了防止啟動前灌入泵殼內(nèi)的液體從殼內(nèi)流出?？諝鈴奈牍艿肋M(jìn)到泵殼中都會造成氣縛。 </p> <p> <p> 按其機(jī)械結(jié)構(gòu)可分為閉式、半閉式和開式三種 </p> <p> 閉式葉輪適用于輸送清潔液體；半閉式和開式葉輪適用于輸送含有固體顆粒的懸浮液，這類泵的效率低。 </p>
