一、S型單級雙吸離心泵的應(yīng)用范圍：
S型單級雙吸離心泵的零件用不銹鋼板壓制，經(jīng)激光焊接而成，并有多種牌號的不銹鋼可供選用，因而S型離心泵的用途十分廣泛，主要適用于輸送各種潔凈水及輕腐蝕液體，可用于住宅供水及增壓、工業(yè)鍋爐給水、空調(diào)系統(tǒng)循環(huán)體會水、水處理和反滲透系統(tǒng)、食品工業(yè)、醫(yī)藥工業(yè)用水等。
二、S型單級雙吸離心泵的工作條件：
流量范圍：0.8m3/h~120 m3/h;
揚程范圍：5.6m~330m;
溫度范圍：-20℃~120℃;
輸送液體種類：各種清潔水及輕腐蝕液體;
離心泵泵腔承壓：≤4.0MPa。
三、S型單級雙吸離心泵的結(jié)構(gòu)特點：
1. 結(jié)構(gòu)緊湊 外形美觀，穩(wěn)定性好，便于安裝。
2. 運行平穩(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，離心泵泵殼內(nèi)表面及葉輪表面具有抗汽蝕性能。
3. 軸承選用SKF及NSK軸承保證運行平穩(wěn)，噪音低，使用壽命長。
4. 軸封選用機械密封或填料密封。能保證8000小時運行無泄漏。
5. 離心泵安裝形式 裝配時不需調(diào)整，可根據(jù)現(xiàn)場使用條件。分立式或臥式安裝。
6. 加裝自吸裝置，可實現(xiàn)自動吸水，即不需安裝底閥，不需真空泵，不需倒灌，離心泵可以啟動。
