style="text-indent:25px">板式換熱器：很典型的間壁式換熱器，它在工業(yè)上的應(yīng)用有著悠久的歷史，而且至今仍在所有換熱器中占據(jù)主導(dǎo)地位。主體結(jié)構(gòu)由換熱板片以及板間的膠條組成。長期在市場占據(jù)主導(dǎo)地位，但是其體積大，換熱效率低，更換膠條價格昂貴（膠條的更換費用大約占整個過程的1/3-1/2）。主要應(yīng)用于液體-液體之間的換熱，行業(yè)內(nèi)常稱為水水換熱，其換熱效率在5000w/m2.K。為提高管外流體給熱系數(shù)，通常在殼體內(nèi)安裝一定數(shù)量的橫向折流檔板。折流檔板不僅可防止流體短路，增加流體速度，還迫使流體按規(guī)定路徑多次錯流通過管束，使湍動程度大為增加。常用的檔板有圓缺形和圓盤形兩種，前者應(yīng)用更為普遍。板式換熱將逐漸退出食品，飲料，制藥等衛(wèi)生級別高的行業(yè)。汕頭換熱器板式換熱器傳熱效率的樞紐是進步傳熱系數(shù)和對數(shù)均勻溫差。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="河源換熱器怎么樣,換熱器" src="https://tyunfile.71360.com/UploadFile/xinchen/637329939767607422/3058394.png"></div><p style="text-indent:25px">換熱器機組保養(yǎng)一般情況下不解體清洗，可以用水與介質(zhì)流動想反方向沖刷，這樣就可以沖出通道里面少量的泥沙沉積物。板式換熱器使用的時間長了板片就會有一定的沉積物，如果不清洗的話就會影響換熱效果，所以換熱設(shè)備應(yīng)根據(jù)實際情況定期須定期拆洗。以供暖領(lǐng)域為例：一般分為幾個階段，全新板式換熱器第１年供暖期結(jié)束清洗，看結(jié)垢情況，如果結(jié)垢層不太厚；以后分為每年2-3次，如果水質(zhì)惡劣，可以每月清洗一次。注意保護好橡膠密封墊。清洗換熱器做好選擇用甲酸清洗液，甲酸清洗液對板片的腐蝕性比較小，甲酸清洗液中在加入緩沖劑和表面活性劑，清洗效果更好，如果有條件建議用專業(yè)的換熱器板片清洗液。</p><p style="text-indent:25px">板式換熱器的特點：1、對數(shù)平均溫差大。2、占地面積小，結(jié)構(gòu)緊湊，清洗方便。3、重量輕，板片的厚度一般在0.4-0.7密碼。4、傳熱系數(shù)高，板片的波紋能使流體在較小的流速下產(chǎn)生湍流。5、可改變換熱面積或流程組合，增加或減少板片數(shù)量即可達到所需要的換熱面積，改變板片的排港列，可適用于不同的換熱器。換熱器外漏的原因是：①夾緊尺寸不到位、各處尺寸不均勻（各處尺寸偏差不應(yīng)大于3 mm）或夾緊螺栓松動。② 部分密封墊脫離密封槽，密封墊主密封面有臟物，密封墊損壞或板式換熱器密封墊片老化。③ 板片發(fā)生變形，組裝錯位引起跑墊。④在板片密封槽部位或二道密封區(qū)域有裂紋。實例：北京、青海和新疆等地的多個熱力站均采用飽和蒸汽作為一次側(cè)熱源供暖，由于蒸汽溫度較高，在設(shè)備運行初期系統(tǒng)不穩(wěn)定的情況下，橡膠密封墊在高溫下失效，引起蒸汽外漏。換熱器在保養(yǎng)的時候，如需更換密封墊，要先將板片用醋酸乙脂清洗干凈。</p><div

style="text-indent:25px">換熱器是一種傳熱效率高，熱損失小，結(jié)構(gòu)緊湊輕巧的新型高效換熱器裝備。主要組成部分是具有一定波紋形狀的金屬片疊裝而成。由于使用壽命時間長，性能優(yōu)越。換熱器被普遍地應(yīng)用于化學(xué)領(lǐng)域，食品領(lǐng)域，機械領(lǐng)域，醫(yī)藥領(lǐng)域。1、換熱器要注意使用環(huán)境的清潔。換熱器不宜在比較臟或者容易結(jié)垢的環(huán)境，操作時的溫度應(yīng)該控制在50℃左右。如果是未經(jīng)軟化的冷卻水作冷卻介質(zhì)時，應(yīng)該定期對板式冷卻器采取化學(xué)清洗或者拆洗！2、及時處理換熱器外漏情況。如果換熱器器發(fā)生外漏，及時找到外漏位置，重新裝配或者更換墊片和板片。3、換熱器的連接管路要適當(dāng)處理。換熱器的連接管路應(yīng)裝90°彎頭，可以避免管路的重量和熱脹冷縮的力直接作用在連接法蘭上。4、開機前將連接管內(nèi)的污水排除干凈開機前，打開泄水閥，將管路內(nèi)的積水和雜物排除，防止開機時發(fā)生水擊或者帶入污物。5、在連接管口處裝溫度計或者壓力表。在用蒸汽加熱時，汽凝水溫度應(yīng)只稍低于蒸汽溫度(以飽和計算)，若下降過大則說明器內(nèi)有積水，這會明顯降低它的傳熱性能。換熱器應(yīng)配有良好的汽凝水排除設(shè)備。板式換熱器除了在特殊情況下的檢修外，還應(yīng)進行定期的維修。汕頭換熱器</p><p
