垂直結(jié)合面泵：即結(jié)合面與軸心線相垂直。 </p> <p> 按泵軸位置來(lái)分類 </p> <p> 臥式泵：泵軸位于水平位置。 </p> <p> 立式泵：泵軸位于垂直位置。 </p> <p> 按葉輪出方式分類 </p> <p> 蝸殼泵：水從葉輪出來(lái)后，直接進(jìn)入具有螺旋線形狀的泵殼。 </p> <p> 導(dǎo)葉泵：水從葉輪出來(lái)后，進(jìn)入它外面設(shè)置的導(dǎo)葉，之后進(jìn)入下一級(jí)或流入出口管。 </p><p> 離心泵是利用葉輪旋轉(zhuǎn)而使水發(fā)生離心運(yùn)動(dòng)來(lái)工作的。水泵在啟動(dòng)前，必須使泵殼和吸水管內(nèi)充滿水，然后啟動(dòng)電機(jī)，使泵軸帶動(dòng)葉輪和水做高速旋轉(zhuǎn)運(yùn)動(dòng)，水發(fā)生離心運(yùn)動(dòng)，被甩向葉輪外緣，經(jīng)蝸形泵殼的流道流入水泵的壓水管路。 </p> <p> 離心泵的基本構(gòu)造是由六部分組成的分別是葉輪，泵體，泵軸，軸承，密封環(huán)，填料函。 </p> <p> 葉輪是離心泵的主要部分，它轉(zhuǎn)速高出力大，葉輪上的葉片又起到主要作用，葉輪在裝配前要通過(guò)靜平衡實(shí)驗(yàn)。葉輪上的內(nèi)外表面要求光滑，以減少水流的摩擦損失。江蘇口碑好離心泵——靖江市瑞鑫泵業(yè)有限公司。</p><div style="width:100%;text-align: center;"><img style="max-width:

它與允許吸上真空高度不能混為一談，水泵產(chǎn)品說(shuō)明書或銘牌上標(biāo)示的允許吸上真空高度是指水泵進(jìn)水口斷面上的真空值，而且是在1標(biāo)準(zhǔn)大氣壓下、水溫20℃情況下，進(jìn)行試驗(yàn)而測(cè)定得的。它并沒(méi)有考慮吸水管道配套以后的水流狀況。而水泵安裝高度應(yīng)該是允許吸上真空高度扣除了吸水管道損失揚(yáng)程以后，所剩下的那部分?jǐn)?shù)值，它要克服實(shí)際地形吸水高度。水泵安裝高度不能超過(guò)計(jì)算值，否則，離心泵將會(huì)抽不上水來(lái)。另外，影響計(jì)算值的大小是吸水管道的阻力損失揚(yáng)程，因此，宜采用zui短的管路布置，并盡量少裝彎頭等配件，也可考慮適當(dāng)配大一些口徑的水管，以減管內(nèi)流速。應(yīng)當(dāng)指出，管道離心泵安裝地點(diǎn)的高程和水溫不同于試驗(yàn)條件時(shí)，如當(dāng)?shù)睾０?00米以上或被抽水的水溫超過(guò)20℃，則計(jì)算值要進(jìn)行修正。即不同海拔高程處的大氣壓力和高于20℃水溫時(shí)的飽和蒸汽壓力。但是，水溫為20℃以下時(shí)，飽和蒸汽壓力可忽略不計(jì)。從管道安裝技術(shù)上，吸水管道要求有嚴(yán)格的密封性，不能漏氣、漏水，否則將會(huì)破壞離心泵進(jìn)水口處的真空度，使離心泵出水量減少，嚴(yán)重時(shí)甚至抽不上水來(lái)。因此，要認(rèn)真地做好管道的接口工作，保證管道連接的施工質(zhì)量。江蘇提供離心泵——靖江市瑞鑫泵業(yè)有限公司。無(wú)錫大型離心泵揚(yáng)程</p><p

h.機(jī)械容差——即使單個(gè)部件的容差值在生產(chǎn)商規(guī)范所規(guī)定的范圍內(nèi)，機(jī)械容差仍可引起機(jī)械內(nèi)的振動(dòng)。簡(jiǎn)言之，泵組裝的零件越多，(在其他條件相同的情況下)容差"累計(jì)"使機(jī)械產(chǎn)生振動(dòng)的風(fēng)險(xiǎn)越大。單個(gè)部件在檢查時(shí)可能在規(guī)范(通常為ASME/)允許的范圍內(nèi)。由于這樣一個(gè)事實(shí)的存在，即采用可能產(chǎn)生問(wèn)題的已加工部件查找并確定其他可能問(wèn)題，上述情況將變得更為復(fù)雜。精確度和垂直狀態(tài)的檢查將難于在實(shí)地準(zhǔn)確測(cè)量，但是這是確定問(wèn)題的途徑。i.在另一方面，如果容差直接涉及轉(zhuǎn)動(dòng)部件，則機(jī)械容差引起的振動(dòng)將易于診斷。"失圓"或"失方"的加工部件可能導(dǎo)致在其他部件內(nèi)出現(xiàn)束縛或磨削。參考下文"外部原因?qū)е抡駝?dòng)"中的內(nèi)容，區(qū)別機(jī)械容差與管道校準(zhǔn)問(wèn)題。j.機(jī)械松動(dòng)——為了便于討論，本文中的機(jī)械松動(dòng)*指螺母和螺栓沒(méi)有恰當(dāng)進(jìn)行緊固的情況。單獨(dú)的螺帽在裝配時(shí)可能沒(méi)有緊固或在運(yùn)輸和安裝過(guò)程中出現(xiàn)松動(dòng)。所有外部螺帽在運(yùn)輸和安裝時(shí)應(yīng)解開(kāi)。生產(chǎn)商每次就裝配提出建議時(shí)，所有外部螺帽應(yīng)緊固并在隨后進(jìn)行定期緊固(對(duì)于大多數(shù)機(jī)械，建議每年緊固一次)。內(nèi)部原因引起的振動(dòng)為了便于進(jìn)行論述，本文中"內(nèi)部原因"指機(jī)器內(nèi)部的原因，不論是在泵的外部或內(nèi)部。無(wú)錫大型離心泵揚(yáng)程</p><p
