SH型大流量雙吸臥式排污泵
H型離心泵,供抽送清水或物理化學(xué)性質(zhì)類似于水的液體之用。被輸送液體溫度不得高于80℃。此泵站在電機(jī)尾部方向看,水泵為逆時針向旋轉(zhuǎn)。 雙吸泵作為離心泵的一種重要形式,因其具有揚(yáng)程高、流量大等特點(diǎn),在工程中得到廣泛應(yīng)用。這種泵型的葉輪實(shí)際上由兩個背靠背的葉輪組合而成,從葉輪流出的水流匯入一個蝸殼中。雙吸泵具有如下一些特點(diǎn):它相當(dāng)于兩個相同直徑的單吸葉輪同時工作,在同樣的葉輪外徑下流量可增大一倍;泵殼水平中開,檢查和維修方便,同時,雙吸泵進(jìn)出口在同一方向上且垂直于泵軸,利于泵和進(jìn)出水管的布置與安裝;雙吸泵的葉輪結(jié)構(gòu)對稱,沒有軸向力,運(yùn)行較平穩(wěn)。在我國黃河沿線地區(qū)提灌泵站流量較大、揚(yáng)程都較高,大多采用雙吸離心泵。南水北調(diào)中線惠南莊泵站也采用了雙吸泵進(jìn)行供水?!?/span>
一、單級雙吸離心泵結(jié)構(gòu)與特點(diǎn)
1. 結(jié)構(gòu)緊湊
外形美觀,穩(wěn)定性好,便于安裝。
2. 運(yùn)行平穩(wěn)
優(yōu)化設(shè)計的雙吸葉輪使軸向力減小到***低限度,且有優(yōu)異水力性能的葉型,并經(jīng)精密鑄造,泵殼內(nèi)表面及葉輪表面極其光華具有顯著的抗汽蝕性能和***率。
3. 軸承
軸承選用瑞典SKF及日本NSK軸承保證運(yùn)行平穩(wěn),噪音低,使用壽命長。
4. 軸 封
選用博格曼機(jī)械密封或填料密封。能保證8000小時運(yùn)行無泄漏。
5.與單級單吸離心泵比較:
雙側(cè)吸入 、流量大、效率高、 揚(yáng)程較高,體積較大?! ?/span>
二、單級雙吸離心泵應(yīng)用范圍:
主要適用于自來水廠、工廠,礦山,城市給水,大型水利工程,農(nóng)田灌溉和排澇,大型泵還可作熱電站循環(huán)泵用,用泵空調(diào)循環(huán)用水、建筑供水、灌溉、排水泵站、電站、工業(yè)供水系統(tǒng)、消防系統(tǒng)、船舶工業(yè)等輸送液體的場合。
