全自動汽液兩相流疏水器的原理：該新型全自動汽液兩相流疏水器，基于“汽、液兩相流”工作原理，自動調(diào)節(jié)加熱器出口疏水流量，從而達(dá)到更為穩(wěn)定的液位，基本原理為：疏水由閥體進(jìn)入閥腔，相變管根據(jù)液位高低采集汽相、液相信號直接進(jìn)入閥腔，與疏水混合后流經(jīng)特定設(shè)計的喉部。當(dāng)液位上升時，汽相信號減少，因而疏水量增加，當(dāng)液位下降時，汽相信號增加，減少喉部有效通流面積，疏水流量降低，達(dá)到有效阻礙疏水的目的，疏水水位則又慢慢升至正常水位。

時產(chǎn)生的壓降一般由三部分組成，即摩擦阻力壓降、重位壓降、加速壓降，管道系統(tǒng)出現(xiàn)閥門、孔 </p> <p> 板等管件時，還需測量局部壓降。目前，常用差壓計或傳感器來測量兩相流壓降。 </p> <p> <br /> </p> <p> 兩相流學(xué)科還處于半經(jīng)驗(yàn)半理論階段， </p> <p>
