style="text-indent:25px">提高板式換熱器傳熱系數(shù)的方式主要有以下幾點(diǎn)：1、提高換熱器板片的表面?zhèn)鳠嵯禂?shù)。由于換熱器的波紋能使流體在較小的流速下產(chǎn)生湍流，因此能獲得較高的表面?zhèn)鳠嵯禂?shù)，表面?zhèn)鳠嵯禂?shù)與板片波紋的幾何結(jié)構(gòu)及介質(zhì)的流動(dòng)狀態(tài)有關(guān)。板片的波形包括人字形、平直形、球形等。一般來說，波紋斷面形狀為三角形的人字形板片具有較高的表面?zhèn)鳠嵯禂?shù)，且波紋的夾角越大，板間流道內(nèi)介質(zhì)流速越高，表面?zhèn)鳠嵯禂?shù)越大。2、減小板式換熱器污垢層熱阻，容積式換熱器批發(fā)報(bào)價(jià)。減小板式換熱器的污垢層熱阻的關(guān)鍵是防止板片結(jié)垢。板片結(jié)垢厚度為1mm時(shí)，傳熱系數(shù)降低約10%。因此，要注意監(jiān)測換熱器冷熱兩端的水質(zhì)，容積式換熱器批發(fā)報(bào)價(jià)，容積式換熱器批發(fā)報(bào)價(jià)，防止板片結(jié)垢，并防止水中雜物附著在板片上。如果水中有黏性雜物，應(yīng)采用**過濾器進(jìn)行處理。板式換熱器是液—液、液—汽進(jìn)行熱交換的理想設(shè)備。容積式換熱器批發(fā)報(bào)價(jià)</p><div

kcal/㎡.h.℃)，因而在同一條件下所需傳熱面積較小。２、重量輕，傳熱面薄，耗用金屬量少，每㎡加熱面只約8kg，*為管式加熱器的1/3～1/4。３、體積小，為緊密型設(shè)備，特別適用于空間有限的場合。４、物料通過時(shí)間短，內(nèi)部死角少，衛(wèi)生條件好，很適合食品工業(yè)應(yīng)用。５、設(shè)備規(guī)范(尺寸)的幅度很大，每件換熱元件(板片)的尺寸，小的可到0.03㎡，大的可達(dá)2㎡以上；每臺設(shè)備的換熱面積，小的可到0.5㎡，大的可達(dá)1000㎡以上。同時(shí)，可以根據(jù)需要增加或減少板片的數(shù)量以改變其加熱面積,或改變工作條件,靈活性大。６、可使用較低溫度的熱源，回收低溫?zé)嵩粗械臒崮?，達(dá)到節(jié)約能源的目的?；葜輷Q熱器供應(yīng)商板式換熱器傳熱效率的樞紐是進(jìn)步傳熱系數(shù)和對數(shù)均勻溫差。</p><div

src="https://tyunfile.71360.com/UploadFile/xinchen/637329939974287109/9287117.png"></div><p style="text-indent:25px">板式換熱器的墊片在使用時(shí)如果發(fā)生滲漏、斷裂、老化等現(xiàn)象，要及時(shí)更換。更換應(yīng)按以下順序進(jìn)行。 1、拆下廢舊墊片。注意拆卸時(shí)，不得使墊片槽內(nèi)有劃痕。 2、用**、**或其它酮類溶劑，去除墊片槽內(nèi)的殘膠。 3、用干凈的布或者是棉紗擦凈墊片槽和墊片。 4、將粘接劑均勻地涂在墊片槽內(nèi)。 5、把干凈的新墊片貼在板上。 6、貼好墊片的板片要放在平坦、陰涼、通風(fēng)的地方自然干固4h后才可安裝使用。對于介質(zhì)流量和壓力變化較大、而且又是多程組合、長期使用的板式換熱器，容易發(fā)生板片錯(cuò)位現(xiàn)象。板片錯(cuò)位后，有時(shí)很快就出現(xiàn)外漏；有些雖然不是立即發(fā)生外漏，但卻是發(fā)生滲漏的一種隱患，所以都必須及時(shí)處理。</p><p style="text-indent:25px">換熱器日常維護(hù)的六個(gè)注意事項(xiàng)：1、換熱器調(diào)節(jié)需要讓專業(yè)的人來負(fù)責(zé)，嚴(yán)格按照說明書步驟規(guī)則運(yùn)行。2、換熱器的上下導(dǎo)桿及螺栓盡可能的多加潤滑油潤滑。3、在清洗的時(shí)候，也讓專門的人檢查一下其他的部分，確認(rèn)傳熱片和膠墊圈是否粘合，密封墊是否完好等等。4、時(shí)刻注意密封墊的情況，如果有脫膠的情況需要立即更換密封墊，避免造成事故。5、壓緊板片的時(shí)候，要記錄壓緊的刻度位置，避免壓緊過度，導(dǎo)致壽命減短。6、運(yùn)作完之后要放置一段時(shí)間，并將換熱器內(nèi)的水清理干凈。后期再校正就可以了。提高換熱器對數(shù)平均溫差的方法為盡可能采用逆流或接近逆流的混合流型。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="容積式換熱器批發(fā)報(bào)價(jià),換熱器"

style="text-indent:25px">水垢是由于水中含有鈣鎂鹽類，部分鈣鎂鹽類的溶解度隨著溫度的升高而下降，析出的結(jié)晶鹽聚集附著在板片上形成水垢。水垢導(dǎo)熱性差，附著在板片上勢必會影響板片的換熱效果。若長時(shí)間得不到有效的清理，越積越多的水垢將減小流通截面（如圖中板片的波紋面），加大流通阻力，嚴(yán)重時(shí)甚至堵塞流通截面。因此，定期清洗水垢是保證板換換熱效果的基礎(chǔ)。目前較常用的清洗方法是化學(xué)清洗殺菌法。在清洗時(shí)，加入化學(xué)劑和殺菌劑，讓板片上的水垢，浮銹，細(xì)菌等與試劑發(fā)生化學(xué)反應(yīng)清洗后排除，還原板片光潔表面。此外，在日常維護(hù)方面，可以適當(dāng)加入緩蝕阻垢劑，防止鈣鎂離子結(jié)晶沉淀。條件好的可以采用磁化及離子棒防垢處理，鈉離子交換處理等方法。換熱器的保養(yǎng)和維修都要進(jìn)行拆卸檢查。容積式換熱器批發(fā)報(bào)價(jià)</p><p

style="text-indent:25px">板式換熱器的特點(diǎn)是傳熱系數(shù)高。由于不同的波紋板是反向的，形成復(fù)雜的通道，使波紋板之間的流體在三維旋轉(zhuǎn)流中流動(dòng)，在較低雷諾數(shù)（一般Re=50-200）下可產(chǎn)生湍流，因此傳熱系數(shù)較高，一般考慮紅色為管殼式的3-5倍。板式換熱器對數(shù)平均溫差大，末端溫差小。在管殼式換熱器中，管程和管程分別有兩種流體流動(dòng)。一般來說，它們是橫流的，且對數(shù)平均溫差修正系數(shù)很小。大多數(shù)板式換熱器都是平行或逆流流動(dòng)，修正系數(shù)一般在0.95左右。此外，板式換熱器中的冷熱流體流動(dòng)與換熱器中的冷熱流體流動(dòng)是平行的。熱表面和無旁路使板式換熱器端部溫差小，對水的傳熱可小于1℃，而管殼式換熱器一般為5℃。容積式換熱器批發(fā)報(bào)價(jià)</p><p
