離心泵是一種葉片泵，依靠旋轉(zhuǎn)的葉輪在旋轉(zhuǎn)過程中，由于葉片和液體的相互作用，葉片將機(jī)械能傳給液體，使液體的壓力能增加，達(dá)到輸送液體的目的。離心泵的啟動要注意四點(diǎn)： </p> <p> 離心泵在一定轉(zhuǎn)速下所產(chǎn)生的揚(yáng)程有一限定值。工作點(diǎn)流量和軸功率取決于與泵連接的裝置系統(tǒng)的情況(位差、壓力差和管路損失)。揚(yáng)程隨流量而改變。 </p> <p> 工作穩(wěn)定，輸送連續(xù),流量和壓力無脈動。 </p> <p> 一般無自吸能力,需要將泵先灌滿液體或?qū)⒐苈烦槌烧婵蘸蟛拍荛_始工作。 </p> <p> 離心泵在排出管路閥門關(guān)閉狀態(tài)下啟動，旋渦泵和軸流泵在閥門全開狀態(tài)下啟動，以減少啟動功率。 </p><p> 使液體自動的流入泵的入口處。當(dāng)入口處的真空度達(dá)到一定程度時，即使在常溫下，入口處的液體也能汽化而產(chǎn)生氣泡，這些氣泡隨液體一起進(jìn)入葉輪。在離心力的作用下液體壓力逐漸升高，氣泡便凝結(jié)成液體而消失，此刻周圍液體迅速來補(bǔ)充，從而發(fā)生了猛烈的碰撞，瞬間產(chǎn)生很強(qiáng)的水錘現(xiàn)象，打擊葉輪表面，便產(chǎn)生機(jī)械腐蝕。一方面葉輪受到損害，同時發(fā)出響聲，泵有振動，流量減小，揚(yáng)程下降，效率降低等，這種現(xiàn)象叫氣蝕現(xiàn)象。離心泵的主要部件有哪些？.離心泵的主要部件有葉輪、泵體、軸、軸承、吸入室、壓出室、密封裝置和平衡裝置等。9、離心泵的葉輪有什么作用？離心泵的葉輪是對葉輪作功的部件。葉輪在泵體內(nèi)有泵軸的帶動下高速旋轉(zhuǎn)，使流過泵的液體獲得能量。也就是說通過葉輪的高速旋轉(zhuǎn)把機(jī)械能傳給液體，使液體才能獲得很高的動壓能。10、離心泵的葉輪是由哪些部件組成？離心泵的葉輪是由前輪板、后輪板、葉片和輪轂四部分組成的。它分為閉式葉輪、半開式葉輪和開式葉輪。11、離心泵的軸向力是怎樣產(chǎn)生的？（1）葉輪兩側(cè)的液體壓力不對稱o（2）液體從葉輪入口流到出口，因流體的流動方向由軸向變?yōu)閺较颍栽谌~輪上產(chǎn)生反作用力。<br>地區(qū)離心泵——靖江市瑞鑫泵業(yè)有限公司供應(yīng)商。</p><div
