德國VERDERAIR雙膜泵工作原理及特性
德國VERDERAIR雙膜泵的工作原理
雙隔膜是一種容積式泵，利用兩個前后往復(fù)運動的柔性隔板，形成一個臨時室，兩者都吸入并排出流體通過泵。隔膜用作空氣和液體之間的分隔壁。
*筆
德國VERDERAIR兩個隔膜通過軸通過空氣閥所在的中心部分連接。空氣閥的目的是將壓縮空氣引導(dǎo)到*個隔膜的背面，使其遠離中心部分。*個隔膜導(dǎo)致沖程將液體移出泵。同時隔膜二號正在進行吸氣沖程。隔膜二號后面的空氣被推到大氣中，使大氣壓力將液體推到吸入側(cè)。吸入球閥被推離其座位，允許流體流過球閥進入液體室。
第二筆
當(dāng)加壓隔膜*號已經(jīng)到達其行程結(jié)束時，空氣的運動通過空氣閥從隔膜的*個到第二個隔膜的后面切換。壓縮空氣將光圈二號離開中心塊，導(dǎo)致隔膜1被拉向中心塊。在泵室二號中，排放球閥被推離其座位，而在第1泵的泵室中則出現(xiàn)相反的情況。在行程完成后，空氣閥將空氣再次引導(dǎo)到*個隔膜的后面，并重新開始循環(huán)。

在哪里可以使用雙面膠膜？
隔膜泵是許多行業(yè)的常見場所。有大量的建筑材料可以產(chǎn)生令人迷惑的數(shù)量的配置，以適應(yīng)困難的流體，例如
腐蝕性化學(xué)品
揮發(fā)性溶劑
粘稠粘稠液體
剪切敏感的食品和制藥產(chǎn)品
臟水和磨料漿
較小的固體
奶油，凝膠和油
除液體處理性能外，還可以為ATEX區(qū)域，EC1935 / 2004，F(xiàn)DA和3A衛(wèi)生應(yīng)用AODD泵，以及其他行業(yè)合規(guī)措施。

為什么使用空氣操作的膠膜泵？
德國VERDERAIR AODD泵是一個多功能的主力，使跨越不同行業(yè)的用戶可以將單個泵類型標(biāo)準(zhǔn)化，用于處理各種流體。只要有壓縮空氣供應(yīng)，泵可以安裝在需要的地方，如果情況發(fā)生變化，可以在工廠內(nèi)移動并輕松切換到其他操作。無論流體被處理是否需要溫和的泵送動作，化學(xué)或物理上是積極的，正位移AODD泵提供了一種和低維護的解決方案。
A double diaphragm is a positive displacement pump which utilises two flexible diaphragms that reciprocate back and forth, creating a temporary chamber, which both draws in and expels fluid through the pump. The diaphragms work as a separation wall between the air and the liquid.
The first stroke
The two diaphragms that are connected by a shaft through the centre section where the air valve is located. The purpose of the air valve is to direct the compressed air to the back of diaphragm number one causing it to move away from the centre section. The number one diaphragm causes a press stroke moving liquid out of the pump. At the same time diaphragm number two is performing a suction stroke. The air behind diaphragm number two is being pushed out to the atmosphere causing atmospheric pressure to push the liquid to the suction side. The suction ball valve is pushed away off its seat allowing the fluid to flow past the ball valve into the liquid chamber.
The second stroke
When the pressurised diaphragm number one has reached the end of its stroke, the movement of the air is switched from diaphragm number one to the back of diaphragm number two by the air valve. The compressed air pushes diaphragm number two away from the centre block resulting in diaphragm number one being pulled toward the centre block. In pump chamber number two the discharge ball valve is pushed off its seat, whilst in pump chamber number one the opposite occurs. Upon completion of the stroke the air valve leads the air again to the back of diaphragm number one and restarts the cycle.
