1、什么叫立式離心泵？立式離心泵的泵軸是水平安裝的。這種泵的結(jié)構(gòu)緊湊，占地面積小，轉(zhuǎn)速小，體積小。吸入口、排出口都是橫向設(shè)置的。本車間沒有立式離心泵。2、什么叫臥式離心泵？臥式離心泵的泵軸式水平安裝的。他的支撐腳落在地面或者支架上，泵軸通過聯(lián)軸節(jié)與電動機(jī)或減速機(jī)連接，這樣維護(hù)、檢修都在地面上工作，所以比較方便3、什么叫單級離心泵？在泵軸上裝兩個或兩個以上葉輪的離心泵叫多級離心泵4、什么叫雙吸泵？液體從葉輪兩側(cè)進(jìn)入泵體的泵叫雙吸泵。液體加給雙吸泵的軸向推力小，上海工業(yè)離心泵價格。生產(chǎn)能力大的泵多為雙吸泵。本車間的G-110A/B熱油泵為雙吸泵。離心泵的工作原理是什么？離心泵在啟動前，先向泵體內(nèi)充滿被輸送的液體，葉輪在泵軸的帶動下轉(zhuǎn)動時產(chǎn)生離心力，液體由葉輪中心被甩到葉輪以外，這時葉輪中心產(chǎn)生負(fù)壓，液體從泵的吸入口流向葉輪中心，泵軸不停地旋轉(zhuǎn)，葉輪不停地吸如何排出液體。離心泵有什么優(yōu)點？離心泵可與電動機(jī)直接相連，轉(zhuǎn)速高，一般為1450r/min或2900r/min，運行平穩(wěn)，流量均勻，壓力波動不大，構(gòu)造簡單，操作方便，效率比較高等，上海工業(yè)離心泵價格。什么叫離心泵的氣蝕現(xiàn)象？離心泵葉輪在高速旋轉(zhuǎn)時產(chǎn)生離心力，上海工業(yè)離心泵價格，使泵入口處產(chǎn)生低于大氣壓的真空度。<br>江蘇地區(qū)離心泵供應(yīng)商——靖江市瑞鑫泵業(yè)有限公司。上海工業(yè)離心泵價格</p><div

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?，所以在葉輪上產(chǎn)生反作用力。<br>靖江市瑞鑫泵業(yè)有限公司——歡迎您的來電。上海工業(yè)離心泵價格</p><p

將需要增加NPSH或排空現(xiàn)有系統(tǒng)內(nèi)的攜入空氣。c.腐蝕和沖蝕——雖然腐蝕和沖蝕問題極易被視為"內(nèi)部問題"，但是其根源在于為泵的抽送能力選擇材料時的不當(dāng)。腐蝕或沖蝕產(chǎn)生的損壞可能毀壞葉輪或頸環(huán)，導(dǎo)致機(jī)械的振動超出限度。需分析泵的抽送能力才能解決這一問題。即使受沙礫沖蝕較厲害，仍需按照步驟更換材料以根除問題或延長MTBF。d.葉輪的不平衡——按照ISO標(biāo)準(zhǔn)1940/1，葉輪應(yīng)該切割到大運行速度時的恰當(dāng)直徑并實現(xiàn)動態(tài)平衡()，該平衡級允許轉(zhuǎn)速為1800時每盎司泵輪重量產(chǎn)生(轉(zhuǎn)速為3600時為)。如果在現(xiàn)有泵上切割葉輪，按照標(biāo)準(zhǔn)平衡葉輪時出現(xiàn)初始故障或重新平衡失敗將導(dǎo)致振動超出可接受的范圍。這一點在各種大、小機(jī)械上均很重要，因為已建立的標(biāo)準(zhǔn)考慮了機(jī)械的總質(zhì)量以及葉輪對振動產(chǎn)生的影響。的解決方法是拆掉葉輪重新進(jìn)行平衡。e.電動機(jī)轉(zhuǎn)動元件的不平衡——這是一種少見的制造缺點。有關(guān)電動機(jī)平衡測試要求請見美國電氣制造業(yè)協(xié)會(NEMA)的標(biāo)準(zhǔn)MG-12007第1節(jié)第7部分。通常情況下，被確定為電動機(jī)轉(zhuǎn)子不平衡(通過斷開電動機(jī)并由其自行運轉(zhuǎn))的問題實際上是曲軸或軸承故障問題，該內(nèi)容已在本文其他部分進(jìn)行討論。電動機(jī)旋轉(zhuǎn)部分的不平衡實際上在啟動時。上海工業(yè)離心泵價格</p><p
