它與允許吸上真空高度不能混為一談，水泵產(chǎn)品說明書或銘牌上標(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)而測定得的。它并沒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計(jì)算值，否則，離心泵將會抽不上水來。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，如當(dāng)?shù)睾０?00米以上或被抽水的水溫超過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℃水溫時的飽和蒸汽壓力。但是，水溫為20℃以下時，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)重時甚至抽不上水來。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。蘇州污水離心泵揚(yáng)程離心泵廠家供應(yīng)就找靖江市瑞鑫泵業(yè)有限公司。</p><div
