還可以減少一次風(fēng)沿轉(zhuǎn)子的上下端面通過徑向間隙漏到二次風(fēng)的漏風(fēng)量；主要由扇形板和徑向密封片及間隙調(diào)整裝置等組成。軸向密封：空預(yù)器在轉(zhuǎn)子外圓周和機(jī)殼之間有較大的空間，如果不采取密封措施，空氣會漏到煙氣中去。為了減少空氣在轉(zhuǎn)子周圍沿其周向漏到煙氣區(qū)，故需裝設(shè)軸向密封裝置。軸向密封裝置由軸向密封片與軸向密封板組成。軸向密封片固定在轉(zhuǎn)子外圓管的徑向倉隔板上，從熱端到冷端，沿著整個轉(zhuǎn)子的高度（即軸向）裝設(shè)。可調(diào)軸向密封板裝于主支座板的內(nèi)側(cè)，與扇形板外側(cè)端相齊平，從熱端延伸到冷端。環(huán)向密封：包括轉(zhuǎn)子外周上、下端處的旁路密封（周向密封）和中心筒密封兩部分。旁路密封分為外環(huán)向密封和內(nèi)環(huán)向密封兩種。外環(huán)向密封是防止空氣通過轉(zhuǎn)子外圓筒的上、下端面漏入轉(zhuǎn)子外圓筒與外殼之間的空隙，再沿這個空隙漏向煙氣側(cè)。內(nèi)環(huán)向密封是防止空氣通過軸的上、下端面漏入煙氣通道，旁路密封主要由旁路密封片和T型鋼組成；中心筒密封片固定在轉(zhuǎn)子中心筒的熱端和冷端端板的圓周上，并隨轉(zhuǎn)子一起旋轉(zhuǎn)。密封片與固定在機(jī)殼的環(huán)形密封盤或密封蓋的凸緣之間保持一定的間隙。板式空氣預(yù)熱器分為蓄熱式和間壁式。安徽空氣預(yù)熱器哪家便宜</p><p

一般各自廠家根據(jù)自己的板型都有自己的選型軟件。國際上通用的軟件有HTRI，HTFS等。通用的計算軟件公開的很少，國內(nèi)一些網(wǎng)站如換熱支持網(wǎng)站提供了提供了板式換熱器的在線計算軟件，可供參考使用。板式換熱器常見故障編輯外漏主要表現(xiàn)為滲漏（量不大，水滴不連續(xù)）和泄漏（量較大，水滴連續(xù)）。外漏出現(xiàn)的主要部位為板片與板片之間的密封處、板片二道密封泄漏槽部位以及端部板片與壓緊板內(nèi)側(cè)。串液主要特征為壓力較高一側(cè)的介質(zhì)串入壓力較低一側(cè)的介質(zhì)中，系統(tǒng)中會出現(xiàn)壓力和溫度的異常。如果介質(zhì)具有腐蝕性，還可能導(dǎo)致板式換熱器密封墊片的腐蝕。串液通常發(fā)生在導(dǎo)流區(qū)域或者二道密封區(qū)域處。壓降大介質(zhì)進(jìn)、出口壓降超過設(shè)計要求，甚至高出設(shè)計值許多倍，嚴(yán)重影響系統(tǒng)對流量和溫度的要求。在供暖系統(tǒng)中，若熱側(cè)壓降過大，則一次側(cè)流量將嚴(yán)重不足，即熱源不夠，導(dǎo)致二次側(cè)出溫度不能滿足要求。供熱溫度不能滿足要求主要特征是出口溫度偏低，達(dá)不到設(shè)計要求。面積相同換熱量的板式換熱器*為管殼式換熱器的1/5。3、容易清洗拆裝方便：板式換熱器靠夾緊螺栓將夾固板板片夾緊，因此拆裝方便，隨時可以打開清洗，同時由于板面光潔，湍流程度高，不易結(jié)垢。海南供暖空氣預(yù)熱器</p><p
