style="color:#0066cc">旋渦泵</span>的作業流量最小可到0.05L/s或更??；流量大的可達12L/s，所以能夠在某些場所取代離心泵。當比轉速Ns趕過40時，因其遵守遠遠低于離心泵，相同一般較少利用。</span></span></span></p> <p><span style="font-size:17px"><span style="color:#222222"><span style="color:#ffffff"><span style="background-color:#ff4c00"><strong><span style="font-size:14px"><span style="color:#0066cc">旋渦泵</span>的優點</span></strong></span></span></span></span></p> <p><span style="font-size:17px"><span style="color:#222222"><span style="font-size:14px">1.比轉速低。</span></span></span></p> <p><span style="font-size:17px"><span style="color:#222222"><span style="font-size:14px">2.結構簡略、重量輕、體積小、制作和修理方便。體積小、重量輕的特色在船只設備中具有極大的優越性。與同樣尺度、轉數相同的離心泵比較，其揚程高2-4倍。與相同揚程的容積泵比較，其尺度要小、結構也簡略。</span></span></span></p> <p><span style="font-size:17px"><span style="color:#222222"><span style="font-size:14px">3.開式漩渦泵有自吸能力；</span></span></span></p> <p><span style="font-size:17px"><span style="color:#222222"><span style="font-size:14px">4.H-Q曲線陡降，在小流量范圍內可取得較高壓頭，因而，對體系中的壓力動搖不靈敏。 </span></span></span></p> <p><span style="font-size:17px"><span style="color:#222222"><span style="font-size:14px">5.某些<span

style="color:#0066cc">旋渦泵</span>不能用來抽送粘性較大的介質。因跟著液體粘性的添加，泵的揚程和功率會急劇下降，介質的粘度限制在114厘沲(15°E)之內。</span></span></span></p> <p><span style="font-size:17px"><span style="color:#222222"><span

style="font-size:17px"><span style="color:#222222"><span style="font-size:14px">5.抽送的介質只限于純潔的液體。當液體中含有固體顆粒時，就會因磨損引起軸向和徑向的空隙增大而下降泵的功能或導致<span

style="font-size:14px">4、用作移動式和固定式的消防泵、船只的供水泵以及用于增壓和抽送補給水等。</span></span></span></p> <p><span style="font-size:17px"><span style="color:#222222"><span style="color:#ffffff"><span style="background-color:#ff4c00"><strong><span style="font-size:14px"><span style="color:#0066cc">旋渦泵</span>的作業原理</span></strong></span></span></span></span></p> <p><span style="font-size:17px"><span style="color:#222222"><span style="font-size:14px">主要由葉輪、泵體和泵蓋組成。葉輪是一個圓盤，圓周上的葉片呈放射狀均勻排列。泵體和葉輪間構成環形流道，吸進口和排出口均在葉輪的外圓周處。吸進口與排出口之間有隔板，由此將吸進口和排出口隔離開。</span></span></span></p> <p><span style="font-size:17px"><span style="color:#222222"><span style="font-size:14px">泵內的液體分為兩部分：葉片間的液體和流道內的液體。當葉輪旋轉時，在離心力的作用下，葉輪內液體的圓周速度大于流道內液體的圓周速度，又因為自吸進口至排出口液體跟著葉輪行進，這兩種運動的組成結果，就使液體發生與葉輪轉向相同的“縱向旋渦”。因而得到<span style="color:#0066cc">旋渦泵</span>之名。需要特別指出的是，液體質點在泵體流道內的圓周速度小于葉輪的圓周速度。</span></span></span></p> <p><span style="font-size:17px"><span style="color:#222222"><span style="font-size:14px">在縱向旋渦過程中，液體質點多次進入葉輪葉片間，經過葉輪葉片把能量傳遞給流道內的液體質點。液體質點每經過一次葉片，就取得一次能量。這也是相同葉輪外徑情況下，<span style="color:#0066cc">旋渦泵</span>比其它葉片泵揚程高的原因。并不是一切液體質點都經過葉輪,跟著流量的添加，“環形活動”削弱。當流量為零時，“環形活動”最強，揚程最高。因為流道內液體是經過液體撞擊而傳遞能量。一起也造成較大撞擊丟失，因而<span style="color:#0066cc">旋渦泵</span>的功率比較低。</span></span></span>旋渦泵|旋渦泵廠家|旋渦泵價格|旋渦泵選型|杭州旋渦泵|浙江旋渦泵|旋渦泵用途</p> <p> </p> </div> </div> </div> <div class="prev_next"> <ul> <li><p><a
