汽液兩相流自動(dòng)控制裝置，產(chǎn)品詳情；新型汽液兩相流自動(dòng)調(diào)節(jié)裝置是我公司近年來研究推廣的一種節(jié)能降耗新技術(shù)產(chǎn)品。該項(xiàng)技術(shù)針對目前電廠上普遍存在的液位控制難題，經(jīng)過多年理論研究和工業(yè)性試驗(yàn)開發(fā)出的科研成果，普遍適用于電廠的各類熱交換器的液位控制。 </p> <p> 該產(chǎn)品同目前工業(yè)上普遍使用的液位調(diào)節(jié)系統(tǒng)相比，摒除了一般機(jī)械運(yùn)動(dòng)部件和電氣控制元件。其基于“汽液兩相流原理”，自調(diào)解容器出口液體的流量，從而達(dá)到相對穩(wěn)定的液位。！ </p><p style="text-indent:25px">氣液兩相流可以增加氣液兩相的接觸面積，提高氣液之間的傳熱傳質(zhì)效率。旋流對促進(jìn)天然氣水合物的形成和確保天然氣水合物漿液的流動(dòng)安全具有重要的實(shí)際應(yīng)用價(jià)值。實(shí)驗(yàn)部分由有機(jī)玻璃管制成，實(shí)驗(yàn)介質(zhì)為空氣和水。根據(jù)高清攝像機(jī)和氣液界面的整體特征，將水平管中氣液兩相渦旋流的流動(dòng)方式進(jìn)行了劃分。研究了水平管中氣液兩相回旋流的流型圖。研究了流速和葉片參數(shù)對壓降的影響。建立了兩種氣液兩相旋流的壓降模型。均相和分裂相壓降模型對旋流氣泡流，旋流分散流，旋流環(huán)形流和旋流分層流具有良好的預(yù)測，預(yù)測誤差帶不大于20％。疏水器的比較高工作溫度根據(jù)蒸汽使用設(shè)備所使用的蒸汽來確定，選擇時(shí)應(yīng)不低于使用蒸汽的溫度。</p><div

減來得到壓降；二是利用差壓傳感器來獲得壓降。 </p> <p> <br /> </p> <p> 第一種方式主要有電容式和壓電式壓力傳感器， </p> <p> 電子設(shè)備將兩壓力傳感器輸入的電信號(hào)相減即 </p> <p> 可換算得兩測壓點(diǎn)之間的壓降。 </p> <p> 適用于需要快速時(shí)間響應(yīng)的場合， </p> <p> 但是有明顯的缺點(diǎn)， </p> <p> 將兩個(gè)** </p> <p> 測出的電信號(hào)再進(jìn)行相減會(huì)引起誤差增大。 </p> <p> 使用此法時(shí)應(yīng)對兩個(gè)壓力傳感器進(jìn)行校準(zhǔn)， </p> <p> 力求使輸出 </p> <p> 信號(hào)能較精確地變換成所需測定的壓降。 </p> <p> 第二種方式主要有磁阻式差壓傳感器和應(yīng)變儀式差壓傳感 </p> <p> 器。 </p> <p> 差壓傳感器可以克服上一種方式的缺點(diǎn)。由于差壓傳感器傳遞壓降時(shí)，膜片位移很小， </p> <p> 因而導(dǎo) </p> <p> 壓管中流體流動(dòng)量較小時(shí)， </p> <p> 氣泡不易進(jìn)入導(dǎo)壓管， </p> <p> 測量結(jié)果更精確。 </p> <p> 當(dāng)應(yīng)用差壓傳感器測量壓降時(shí)， </p> <p> 需用導(dǎo)壓管將測壓點(diǎn)和差壓傳感器連接，此時(shí)導(dǎo)壓管中也要全部充滿液體隨著兩相流以一混合速度流動(dòng)時(shí)，氣相向前或向后相對于這個(gè)混合速度有一個(gè)漂移速度。連云港哪里有生產(chǎn)汽液兩相流水位控制裝置廠家</p><p
