所有的水泵和旋轉(zhuǎn)機(jī)械都會(huì)產(chǎn)生振動(dòng)。振動(dòng)的產(chǎn)生是無(wú)法避免的，也不是泵本身的問(wèn)題：經(jīng)設(shè)計(jì)者(以及電動(dòng)機(jī)設(shè)計(jì)者)設(shè)計(jì)的泵能承受正常限度內(nèi)的振動(dòng)。這些振動(dòng)限度隨泵的類型、安裝配置、供電要求、旋轉(zhuǎn)速度以及泵送的液體等的差異而發(fā)生變化。水力資源協(xié)會(huì)出版了美國(guó)國(guó)家標(biāo)準(zhǔn)協(xié)會(huì)(ANSI)所采用的一整套標(biāo)準(zhǔn)，其內(nèi)容涵蓋了振動(dòng)動(dòng)力學(xué)、測(cè)量標(biāo)準(zhǔn)以及允許限度。該標(biāo)準(zhǔn)為ANSI/。通常情況下，如不造成明顯問(wèn)題大部分的振動(dòng)都忽略不計(jì)(但不建議忽略)。過(guò)度振動(dòng)可能導(dǎo)致噪音過(guò)大、設(shè)備損壞以及過(guò)早疲勞失效。近幾年內(nèi)開(kāi)發(fā)的BAC網(wǎng)絡(luò)、SCADA系統(tǒng)以及建筑管理系統(tǒng)和生產(chǎn)商設(shè)計(jì)和開(kāi)發(fā)的系統(tǒng)已頻繁用于測(cè)量和記錄泵內(nèi)的振動(dòng)。確立基準(zhǔn)參考值、確定限度以及將振動(dòng)測(cè)量值并入預(yù)防性維修計(jì)劃等，通常將在振動(dòng)引起重大故障或其他無(wú)法預(yù)知的后果之前保證泵的正常服務(wù)。但是振動(dòng)本身并不是"根本性問(wèn)題"：振動(dòng)由泵內(nèi)部或系統(tǒng)內(nèi)部的某個(gè)部件引起。水泵振動(dòng)產(chǎn)生的三大原因1.誤用、設(shè)計(jì)或制造引起的振動(dòng)2.內(nèi)部原因引起的振動(dòng)3.外部原因引起的振動(dòng)由上述任一類原因引起的振動(dòng)通常將導(dǎo)致其加劇達(dá)到一個(gè)將導(dǎo)致另一原因下出現(xiàn)故障的水平。誤用、設(shè)計(jì)或制造引起的振動(dòng)目前這一類原因?yàn)樯僖?jiàn)。</p><p> 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(shū)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。江蘇地區(qū)訂制離心泵——靖江市瑞鑫泵業(yè)有限公司。</p><div
