style="text-indent:25px">過去很多發(fā)電廠加熱器上所用疏水裝置一般為：浮球式、氣動(dòng)式、電動(dòng)式，它們普遍存在調(diào)節(jié)卡澀、靈敏度不高，液位誤差率大等缺點(diǎn)，有的不得不改為手動(dòng)，則增大了操作人員勞動(dòng)強(qiáng)度，給設(shè)備的經(jīng)濟(jì)性、安全性帶來嚴(yán)重影響，有時(shí)發(fā)生失控現(xiàn)象給運(yùn)行人員造成誤操作，給機(jī)組安全運(yùn)行造成威脅，同時(shí)液位失控使機(jī)組安全經(jīng)濟(jì)運(yùn)行得不到保證。為了克服以上存在的問題，連云港廣潤機(jī)械設(shè)備有限公司特推出全自動(dòng)汽液兩相流疏水器，經(jīng)多年上百家單位推廣使用，深受客戶接受與好評(píng)。</p><p style="text-indent:25px">圓盤式蒸汽保溫型疏水閥疏水閥的工作原理和熱動(dòng)力式疏水閥相同，它在熱動(dòng)力式疏水閥的汽室外面增加一層外殼。外殼內(nèi)室和蒸汽管道相通，利用管道自身蒸汽對(duì)疏水閥的主汽室進(jìn)行保溫。使主汽室的溫度不易降溫，保持汽壓，疏水閥緊緊關(guān)閉。當(dāng)管線產(chǎn)生凝結(jié)水，疏水閥外殼降溫，疏水閥開始排水；在過熱蒸汽管線上如果沒有凝結(jié)水產(chǎn)生，疏水閥不會(huì)開啟，工作質(zhì)量高。閥體為合金鋼，閥心為硬質(zhì)合金，該閥比較高允許溫度為550℃，經(jīng)久耐用，使用壽命長，是高壓、高溫過熱蒸汽**疏水閥。疏水器的公稱壓力不能低于蒸汽使用設(shè)備的比較高工作壓力。</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(cè)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(chǎng)合， </p> <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(cè)量結(jié)果更精確。 </p> <p> 當(dāng)應(yīng)用差壓傳感器測(cè)量壓降時(shí)， </p> <p> 需用導(dǎo)壓管將測(cè)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在一維流動(dòng)的基礎(chǔ)上，為研究方便期間，根據(jù)流動(dòng)現(xiàn)象，通常有以下幾種主要的簡(jiǎn)化模型。連云港銷售汽液兩相流水位控制裝置報(bào)價(jià)</p><p
