汽液兩相流自調(diào)節(jié)液位控制器是基于流體力學(xué)理論和控制原理，利用汽液兩相流的流動(dòng)特性設(shè)計(jì)的一種全新概念的液位控制器，屬自力式智能調(diào)節(jié)，需消耗少量的汽（約為排水量的1-2%）作為執(zhí)行機(jī)構(gòu)的驅(qū)動(dòng)源。該控制器連接系統(tǒng)如圖所示。調(diào)節(jié)器的作用是控制出口水量，相當(dāng)于自動(dòng)調(diào)節(jié)系統(tǒng)中的執(zhí)行機(jī)構(gòu)。其調(diào)節(jié)原理是：當(dāng)加熱器的水位升高時(shí)，信號(hào)管內(nèi)的水位隨之上升，導(dǎo)致發(fā)送的調(diào)節(jié)汽量減少，因而流過調(diào)節(jié)器中兩相流的汽量減少、水量增加，加熱器的水位隨之下降。反之亦然。由此實(shí)現(xiàn)了加熱器水位的自動(dòng)控制。 </p> 氣液兩相的流速并不相等，只有在高含氣量或者是很小含氣量時(shí)兩相流速才相等。連云港哪里有銷售疏水器廠家</p><p style="text-indent:25px">疏水器的作用是阻止蒸汽通過，而把凝液排出去，起汽液分離作用，保持運(yùn)行蒸汽管中不帶水。連云港凝汽器除氧補(bǔ)水裝置價(jià)格</p><p> 壓降， </p> <p>
