一.概述
1.用途：HW混流泵為臥式，單級(jí)，單吸，渦殼式混流泵。適用于輸送清水或物理，化學(xué)性質(zhì)類似于水的其它液體。被輸送液體溫度不宜高于50度。廣泛用于農(nóng)田灌溉，工業(yè)和城市排水等多種場(chǎng)合。HW泵的性能范圍：流量90-9000m3/h 揚(yáng)程3.5-22m。
2. 特點(diǎn)：結(jié)構(gòu)簡(jiǎn)單，使用可靠，裝修方便，而且效率高，體型小，重量輕。jdhuiquan4.9
3. 傳動(dòng)方式：用直接傳動(dòng)和變速傳動(dòng)。常用動(dòng)力機(jī)是電動(dòng)機(jī)和柴油機(jī)。訂貨 時(shí)應(yīng)明確動(dòng)力機(jī)的型號(hào)，以便確定聯(lián)軸器和皮帶輪的型號(hào)
4.型號(hào)說(shuō)明：以150HW-8S例
150---------泵進(jìn)出口直徑mm
8------------設(shè)計(jì)揚(yáng)程 m
S------------變型代號(hào)

二.結(jié)構(gòu)和作用
1.HW型泵主要有泵蓋，葉輪，泵體，泵軸，軸套，及軸承體等主要零件組成。 泵蓋分別與泵體和進(jìn)水管相接。2.泵蓋平面與葉輪平面之間應(yīng)有適當(dāng)間隙。間隙過(guò)小會(huì)產(chǎn)生摩擦，間隙過(guò)大，會(huì)導(dǎo)致泵體內(nèi)的壓力水大量回流，是泵的效率降低。實(shí)際使用的適宜間隙為0.3-0.7mm，間隙可用增減紙墊厚度來(lái)調(diào)整。
3.軸套用以保護(hù)泵軸，磨損后應(yīng)及時(shí)更換。
1.泵體上端的螺孔，用于加灌引水或連接真空泵抽氣引水。
2.為擴(kuò)大泵的適用范圍，滿足用戶不同需求，可切割葉輪外徑或換用不同性能的葉輪。
