class="title">詳細(xì)說明</p><div id="utqszli" class="box"><p><p style="text-indent:25px">以下是小編整理的板式換熱器產(chǎn)品選用要點供大家參考 ⒈ 板式換熱器選用控制參數(shù)為換熱器材質(zhì)、工作壓力、設(shè)計溫度等。 ⒉ 選用換熱器時，應(yīng)盡量使換熱系數(shù)小的一側(cè)得到大的流速，并且盡量使兩流體換熱面兩側(cè)的換熱系數(shù)相等或相近，提高傳熱系數(shù)。經(jīng)換熱器加熱的流體溫度應(yīng)比換熱器出口壓力下的飽和溫度低10℃，深圳換熱器定制，且應(yīng)低于二次水所用水泵的工作溫度。 ⒊ 含有泥沙臟物的流體宜經(jīng)過過濾后進(jìn)入換熱器。 ⒋ 選用板式換熱器時，溫差較小側(cè)流體的接口處流速不宜過大，深圳換熱器定制，應(yīng)能滿足壓力降的要求。 ⒌ 對于流量大允許壓力降小的情況應(yīng)選用阻力小的板型，反之，選用阻力大的板型。 ⒍ 根據(jù)流體壓力和溫度情況選用可拆卸式或電焊式。 ⒎ 不宜選用單板面積太小的板片，深圳換熱器定制，以免板片數(shù)量過多，板間流速偏小，降低傳熱系數(shù)。 ⒏ 板式換熱器的換熱介質(zhì)不宜為蒸汽。換熱器的保養(yǎng)和維修都要進(jìn)行拆卸檢查。深圳換熱器定制</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="深圳換熱器定制,換熱器" src="https://tyunfile.71360.com/UploadFile/xinchen/637329939763076172/3005646.png"></div><p style="text-indent:25px">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。板片加厚，能進(jìn)步換熱器的承壓能力。該方式應(yīng)采用逆流布置，使冷介質(zhì)出換熱器的溫度較高，保證換熱器出口合流后的冷介質(zhì)溫度能達(dá)到設(shè)計要求。板換式換熱器的效能是一個綜合經(jīng)濟(jì)效益題目，應(yīng)通過技術(shù)經(jīng)濟(jì)比較后確定。采用對稱型或非對稱型、單流程或多流程板換式換熱器，均可設(shè)置換熱器旁通管，但應(yīng)經(jīng)具體的熱力計算。在知足換熱器承壓能力的條件下，應(yīng)盡量選用較小的板片厚度。多流程組合泛起混合流型，均勻傳熱溫差稍低。深圳換熱器定制由于板式換熱器的應(yīng)用領(lǐng)域不斷擴(kuò)大，對于不同的介質(zhì)和工藝有不同的耐溫、耐壓和耐腐蝕的要求。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="深圳換熱器定制,換熱器" src="https://tyunfile.71360.com/UploadFile/xinchen/637329939770224609/9531857.png"></div><p style="text-indent:25px">板式換熱器的型號以板片的型號來展示，每種型號的板片有一定的換熱面積和傳熱特性。每臺換熱器所用板片的數(shù)量視所需的總面積而定，變化幅度可以很大。換熱器的框架長度則按安裝板片的需要，每種型號均有幾個不同長度的等級。板式換熱器的板片是垂直放置的，物料從上方入，下方出；或從下方入，上方出；冷和熱的物料安排成反方向流動，以取得較大的有效溫度差，達(dá)到較高的效率。如果用蒸汽加熱，應(yīng)從上方進(jìn)汽，下方排出凝縮水，被加熱的物料則從下方入，上方出。板式換熱器通常用單程的工作方式，這對板片和連接管路的布置是較有利的。在大多數(shù)情況下，適當(dāng)?shù)剡x擇板片的型式和參數(shù)，可以用單程達(dá)到所需的熱交換參數(shù)。但在某些特殊情況下，也可用雙程或四程的方式(但絕不需要象管式加熱器那樣用很多程)。</p><p style="text-indent:25px">板式換熱器是往清洗槽內(nèi)注水直至傳熱片被完全淹沒。加入適量清洗劑,開始循環(huán)清洗。按照化學(xué)清洗工藝,在循環(huán)過程中,每隔1ｈ要檢測一次清洗槽內(nèi)清洗劑的濃度,使清洗劑的濃度始終保持在0.10～0.15ｍｏｌ/Ｌ安全有效的范圍內(nèi),并根據(jù)測量數(shù)據(jù)添加清洗劑。清洗前期,反應(yīng)比較劇烈,有大量泡沫出現(xiàn),可噴灑消泡劑消泡,同時清洗液濃度下降較快,清洗液濃度可適當(dāng)高一點兒。當(dāng)清洗劑的濃度連續(xù)2ｈ內(nèi)不變化或變化量極小,同時觀察到傳熱片表面水垢明顯減少,用塑料刷子輕輕一刷就可刷掉,此時可視為到清洗終點?；瘜W(xué)清洗結(jié)束后,逐片取出傳熱片,用清洗機(jī)將傳熱片兩面的余垢掃除,必要時用塑料刷協(xié)助刷洗。清洗過程中清洗機(jī)壓力不要太高,以490～588ｋＰａ為宜,水柱不要與傳熱片垂直,應(yīng)有一定夾角,以免將傳熱片損壞。同時還應(yīng)注意傳熱片的順序和傳熱片上的密封墊的安全。換熱器是將熱流體的部分熱量傳遞給冷流體的設(shè)備。</p><div

style="text-indent:25px">換熱器的優(yōu)點有：板式換熱器的板厚*為0.4-0.8 mm，殼管式換熱器的管厚為2.0-2.5 mm。管殼式換熱器比板式換熱器框架重得多。板式換熱器一般只占管殼重量的1/5左右。價格低。板式換熱器材料相同，換熱面積相同，價格比管殼式換熱器低40%~60%。制作方便。板式換熱器的傳熱板經(jīng)過沖壓加工，具有很高的標(biāo)準(zhǔn)化程度，可大批量生產(chǎn)。管殼式換熱器通常是手工制造的。容易清洗?？蚣馨迨綋Q熱器只要松開壓力螺栓，就可以松開板式換熱器管束，拆下板式換熱器進(jìn)行機(jī)械清洗。這對于需要經(jīng)常清洗的設(shè)備的換熱過程非常方便。熱損失小。在板式換熱器中，只有換熱板的殼板暴露在大氣中，熱損失可以忽略不計，不需要采取保溫措施。板式換熱器具有結(jié)構(gòu)緊湊，換熱效率高，安裝方便，占地面積小，維護(hù)成本低等諸多優(yōu)點。惠州換熱器怎么選</p><p
